INSTALLATION
The gas stove is shipped with a flexible connector that has a 1/2” NPT female connection. The gas supply
piping should have a separate gas shutoff valve and a 1/8” NPT plugged tapping upstream of the valve. The
stove and its main control valve must be disconnected from the gas supply piping system during any pres-
sure testing of that system at test pressures in excess of 1/2 psi (3.5 kPa). The stove must be isolated from
the gas supply piping system by closing the main control valve during any pressure testing of the gas supply
system at test pressures equal to or less than 1/2 psi (3.5 kPa). After the gas supply has been connected, use
a commercial gas leak detector or apply a soapy water solution to all the fittings to check for gas leaks.
Never use a flame to test for leaks.
REQUIREMENTS FOR THE COMMONWEALTH OF MASSACHUSETTS
This product must be installed by a licensed plumber or gas fitter when installed within the Com-
monwealth of Massachusetts. If this appliance is installed in a dwelling, building or structure used in
whole or in part for residential purposes and the installation includes a horizontal vent termination
that is less than seven (7) feet above the finished grade in the area of the venting, including but not
limited to decks and porches, a hard-wired carbon monoxide detector with an alarm and battery
back-up must be installed on the floor level of the dwelling, building or structure where the appli-
ance is to be installed.
Additionally, a hard-wired or battery operated carbon monoxide detector with an alarm must be in-
stalled on each additional level of the dwelling, building or structure served by the appliance. It shall
be the responsibility of the property owner to secure the services of qualified licensed professionals
for the installation of hard-wired carbon monoxide detectors.
In the event that the horizontally vented appliance is installed in a crawl space or attic, the hard-
wired carbon monoxide detector with alarm and battery back-up may be installed on the next adja-
cent floor level.
In the event that this requirement cannot be met at the time of completion of the installation of the
appliance, the owner shall have a period of thirty (30) days to comply with the requirement. How-
ever, during said thirty (30) day period, a battery operated carbon monoxide detector with alarm
must be installed.
Each carbon monoxide detector as required in accordance with the above provisions must comply
with NFPA 720 and be ANSI/UL 2034 and IAS certified.
In addition when the stove is horizontally vented and the vent termination is less than seven (7) feet
above finished grade a metal or plastic identification plate must be permanently mounted to the exte-
rior of the building at a minimum height of eight (8) feet above grade directly in line with the ex-
haust vent terminal. The sign shall read, in print size no less than one-half (1/2) inch in size, “GAS
VENT DIRECTLY BELOW. KEEP CLEAR OF ALL OBSTRUCTIONS”.
A COPY OF THESE INSTRUCTIONS PLUS ALL VENTING INSTRUCTIONS WHICH IN-
CLUDE PARTS LISTS, AND/OR ALL VENTING DESIGN INSTRUCTIONS MUST REMAIN
WITH THE STOVE AT THE COMPLETION OF THE INSTALLATION.
ATTENTION INSTALLERS: Mark below which venting system was used in the installation. These
instructions must remain with the GABO Installation & Operation Manual.

direct venting components. For specific installation requirements, fol-
low the installation instructions included by the venting manufacturer with the venting system components
you have chosen. The total vent length may not exceed 36 feet, including vertical rise and horizontal run.
The vent lengths are measured from the stove, not the floor. The minimum vertical vent rise when using a
vertical vent termination is 10 feet. The minimum vertical rise required when using a horizontal vent termi-
nation is 2 feet. The maximum allowed horizontal vent run is 12 feet when the venting includes at least 5
feet of vertical rise. The maximum allowed horizontal vent run for vertical rises of less than 5 feet is shown
in the venting charts. No more than three elbows may be used in any installation. The venting charts are
set up for installations that use no elbows or that include the use of one elbow. For the second or third el-
bows that are included in the installation, add 4 feet to the actual horizontal run for each elbow to determine
the equivalent horizontal run for the installation.
The venting charts allow a simple way to determine the recommended initial settings for both the air inlet
restrictor and the exhaust baffle. These settings have been determined by extensive testing and will be a
good starting point while setting up the stove. Small adjustments from these settings may be needed to ac-
count for specific installation variables. Please see the instructions on pages 19 & 20 for information on
how to adjust the restrictors.
The numbers (1-7) designate the position of the air inlet restrictor. The higher the number, the greater the
restriction. There is a position indicator line on the adjuster handle. When ½ or ¾ is added to the number
designation, this indicates that the position is halfway or three-quarters between adjacent numbers. Use the
long lines which represent the halfway position between the numbers as a guide. The letters (A-F) indicate
the position of the exhaust baffle. The higher the letter, the greater the restriction. Use the top edge of the
adjuster handle as the position indicator. When +, ⅛, ¼, ⅜, ½,
⅝, ¾ or ⅞ is added to the letter designation,
this indicates that the position is fractionally between adjacent letters. For example, E ⅞ is halfway be-
tween E ¾ and F. Use the lines between the letters as a guide. F ⅛ is the first line past F. If F + corre-
sponds to your recommended settings, this is halfway between F and F ⅛. Note: Although some of the rec-
ommended settings represent only small incremental differences on the setting indicators, the change in the
actual air inlet restrictor or exhaust baffle position is significant.
To use the charts, determine the horizontal run length and vertical rise length (in feet) for your installation.
If more than one elbow is used, add 4 feet to the actual horizontal run length for each additional elbow to
calculate the equivalent horizontal run for the chart. Note: Remember that a maximum of three elbows is
allowed. Select the venting chart for the fuel type (Natural Gas or Propane (LP) Gas) and find the box on
the chart that corresponds to the vertical rise and actual horizontal run (or equivalent horizontal run, if two
or three elbows are used) and read the settings for the inlet air restrictor (1-7) and exhaust baffle (A-F⅛).
Examples are shown page 9. Use these as a guide for your particular installation.
Note: The GABO is shipped from the factory with inlet air restrictor and exhaust baffle set for 2 feet of
vertical rise and 1 foot of horizontal run and for natural gas.
The GABO is shipped with a Simpson DuraVent GS
®
starter section that is specifically designed for the
GABO. Regardless of the venting brand you chose, you must use the DuraVent starter section that was
provided with your stove. All of the venting brands listed for use with the GABO are compatible with the
provided starter section. For venting system installation details, refer to the instructions provided with the
venting system you have chosen. Each brand has specific installation requirements that must be followed to
insure a safe and functional venting system for your GABO.

VENTING
PLEASE NOTE: If your specific venting configuration falls in a box in the venting charts (on pages 10 &
11) that is above the dotted line ( ), you must use one of the approved direct vent venting systems
that utilizes a stainless steel inner liner. This requirement is part of the ANSI standards and is based on test-
ing conducted to determine where the exhaust gas temperature drops to the point where condensation might
occur in the vent pipe. The standards require the use of corrosion resistant liner materials if that specific
total vent length is exceeded.
REAR VENTING DIRECTLY THROUGH THE WALL TO A STANDARD HORIZONTAL
VENT TERMINATION
The Gabo Gas Stove can be vented in rear exit with up to 18” of horizontal pipe (and no vertical pipe) util-
izing a standard horizontal vent termination. However, in order for the stove to operate properly, the gas
input rate to the stove must be reduced by down-sizing the main fuel orifice that came installed in the
stove. The replacement orifices for this purpose are shipped with the stove or are available from your
RAIS dealer. The Gabo is shipped from the factory set up to burn natural gas. If you are burning natural
gas, replace the standard orifice with the #39 orifice following the instructions on page 23. If you will be
burning propane, install the #53 orifice when the fuel conversion is done. Refer to pages 23 & 24.
For either fuel, the inlet air restrictor and exhaust outlet baffle should be set at their full open positions to
minimize flow resistance. This corresponds to a setting of 1 for the air inlet setting and A for the exhaust
baffle setting. Please note: It is highly recommended that a 14” snorkel vent termination be used for this
type of installation. Including a 14” snorkel can reduce the variability in performance that can occur due
to the low draft associated with this type of installation.
Also note: If a 36” snorkel vent termination is used, the gas input rate to the stove does not have to be re-
duced. To determine the appropriate air inlet restrictor and exhaust baffle settings if using a 36” snorkel,
refer to the venting chart settings on pages 10 & 11 for your fuel type and use 3’ for the vertical rise. Use
the horizontal run that corresponds most closely to your installation. For up to 12” of horizontal run, use
the 1’ box. For 12” to 18” of horizontal run, use the 2’ box. Some fine-tuning from these settings may be
desirable. Please refer to page 20 for additional information.

controller. Connect the two
wires from the optional
thermostat or controller to the
terminal block located under the
bottom left of the firebox. The
wires may go to either terminal.
Caution: Label all wires prior
to disconnection when servicing
the controls. Wiring errors can
cause improper and dangerous
operation. Verify proper
operation after servicing.

ASSEMBLY
UNPACKING AND PLACING THE GABO
By now, you will have removed the shipping carton from the base pallet. The GABO is shipped in a spe-
cially designed shipping carton Cut the strapping that secures the stove to the pallet and remove the
wooden cribbing from the top of the stove. Remove the plastic bag that covers the stove. Remove the
package of logs and accessories that is packed in the space under the stove and set aside. Lift the stove up
and off the pallet. The best place to lift is at the base of firebox. Note: The stove front and the glass
frame/glass assembly have to be removed in order to install the logs. Removing them now will reduce the
weight and make it easier to lift the stove. Remove transit packing material from between the stove front
and the louver and then remove the stove front by lifting it straight up to disengage the keyhole slots from
the pins that secure it to the sides. Once it is disengaged, you can move the front away from the stove body.
Set the front aside with the back side down to protect the outer surface.
With the stove front removed and set aside, remove the glass panel and frame assembly. The latches are
located at the top of the door frame. Lift the latch handles up and disengage the latch rods from the slots in
the glass frame. Lift the glass and frame assembly up and off the stove and set aside in a safe place. Re-
move any packing material from inside the firebox. See the two illustrations below.
The GABO is equipped with leveling bolts to make it easier to install
the stove on an irregular surface. The leveling bolts are shipped in the
accessory box that was packed in the space under the firebox. Once you have unpacked the leveling bolts,
install them in the base plate of the stove. This will require a helper as the stove must be tipped up on the
base, first to one side and then the other to allow the leveling bolts to be screwed in from the bottom. For
right now, be sure all four leveling bolts are screwed in all the way. They can be adjusted later. See the
illustration below for leveling bolt locations.
Move the GABO to location where it will be installed. Using as little adjustment as possible for each level-
ing bolt, adjust them as needed to get the stove as level as possible
both side to side and front to back.
Once the GABO is in its final location, remove the transit tape
from the relief door. The relief door can be identified by the five
vertical ribs on its top surface and is located directly adjacent to the
glass frame latches on the top of the firebox. This tape must be re-
moved to insure proper operation of the relief door.
Also, remove the tie wrap that secures the control access panel dur-
ing shipping. It is located on the right side of the panel and can be
cut with a knife or scissors.
The GABO Gas Stove is shipped from the factory equipped to burn
natural gas. If you will be burning propane (LP) gas you must con-
vert the stove by replacing the burner orifice and valve regulator and
adjusting the pilot fuel selector plate and primary burner air setting.
This should be done before the stove is set up. Follow the instruc-
tions on pages 23 & 24.

Place the right cross log next. Use the recessed
area at the front right corner of the burner top that
corresponds to the shape of the base of the cross
log. Place the charred end of the log in the recess
and guide the alignment pin hole in the underside
of the log onto the rear alignment pin in the arch
log.
The adjacent illustration shows the proper positions
for the first two logs.
ASSEMBLY
LOGS AND EMBERS
Carefully unpack each of the three logs and the em-
ber chunk from the log and accessory box. The logs
and ember chunk are somewhat fragile and will not
survive being dropped from any significant height.
If you haven’t already done so, remove any protec-
tive cover material from the top of the burner.
Each of the three logs is unique and must be placed
in a precise location on top of the burner. The burner
and log system is designed to facilitate correct place-
ment of the logs. Flat recessed areas on the burner
top are keyed to each of the main logs. See the adja-
cent illustration.
Place the arched log first. There is recessed area in
the left front corner of the burner top as well as right
rear corner. The charred area on the log faces the
front of the stove. When correctly positioned, the
log will sit firmly in place without tipping or rock-
ing.
The arched log has two sockets for the ceramic pins
that are included with the log set. These pins locate
the left and right cross logs. Place the pins in the
sockets. Refer to the illustration below.
16
ASSEMBLY
Place the left cross log next. Use the raised platform
at the left rear corner of the burner top to support the
end of the cross log. The split charred end of the log
faces toward the front. Place the pin socket over the
front alignment pin hole in the arch log. You may
have to wiggle the arch log and right cross log to get
the pin socket to drop over the alignment pin. See
the adjacent illustration.
When correctly placed, the logs and ember chunk will look like the illustration below.
Finally, place the ember chunk with the non-
charred end in the corresponding recess in the
burner top per the adjacent illustration. It has a
specific position and orientation and will not rock
when in the proper position.

ASSEMBLY
After the logs and embers have been placed, the next
step is to replace the glass panel and frame. Carefully
pick up the glass and glass frame assembly by grasping
the sides of the frame and using your thumbs and fingers
to hold the glass in place within the gasket and frame.
With the glass frame (and glass) at a slight angle
(leaving room for your fingers between the frame and
the firebox) insert the bottom edge of the frame into the
frame retainers located on the bottom front of the fire-
box. Take care to center the frame from left to right.
Once the bottom edge is in place, move your fingers out
of the way and press the top of the frame against the fire-
box while pushing down to be sure the frame is fully en-
gaged in the frame retainers. Hold the frame in place
with one hand and engage the two glass frame latches by lifting and aligning latch pins into the slots in the
top of the frame. Push the latch handles back and down until they are parallel with the top of the firebox,
similar to the action of a ski boot buckle. See the adjacent illustration.
Top or Rear Vent
The GABO has provisions for either top or rear venting but is shipped from the factory set-up for top vent-
ing. The rear position is sealed with a special cover plate. If your installation requires rear-venting, you
will need to reverse the positions of the starter sec-
tion and the cover plate.
First, remove the top plate of the stove by unscrew-
ing the four decorative top retaining bolts. With the
bolts removed, lift the top up and off the stove body
and set aside.
Remove the four screws that secure the vent starter
section flange to the firebox top and remove the
starter. There are two ceramic fiber gaskets that seal
the starter to the stove. These gaskets are very im-
portant! Take care in handling these gaskets as they
will be re-used. They are somewhat fragile and will
tear if handled roughly. See the adjacent illustration.
Next, remove the stove back plate from the stove.
First remove the two screws at the top of the back
that secure the back plate to the back plate bracket.
Next lift the back plate up to disengage it from the
three slots in the stove base plate. While taking care
not to pull on the wiring harness, rotate the back
plate away from the back of the stove. Refer to the
illustration on page 18. Next break out the rear exit
cover plate from the rear plate.
Remove the vent cover plate from the rear of the stove following the same procedure as the starter again
taking care with the gaskets. Install the cover plate on the top vent opening by reversing the removal proce-
dure. Be sure that the inner and outer gaskets are in their proper positions.

ASSEMBLY
Install and tighten the four screws.
Finally, install the vent starter section in the rear
vent position. Again, make sure that the inner and
outer gaskets are in their proper positions and in-
stall and tighten the four screws.
Replace the stove back plate by aligning the rear
vent cut-out over the vent starter pipe. Next align
the three tabs on the bottom of the back plate with
the corresponding slots in the stove base plate. If
the fit is tight, work from one side to the other, en-
gaging the tabs sequentially. Once the tabs are en-
gaged, re-install the two fasteners that secure the
top of the back plate.
Reinstall the top plate using the four decorative fas-
teners.
A filler plate is provided for the vent cut-out in the
top plate. The filler plate is located in the acces-
sory box that was included with the stove. Once
you have re-installed the top plate, simply drop the
filler plate in place.
PRIMARY AIR ADJUSTER
Your GABO gas stove was shipped from the factory equipped for use with natural gas and the primary
burner air adjuster was set at the factory at the recommended position fully closed position for that fuel.
However, it is a good idea to confirm that the position is correctly set. The fully-closed position corre-
sponds to the adjuster screw turned in fully.
If you will be using propane (LPG) for your
installation, please see the instructions for fuel
conversion on pages 23 & 24 of this manual.
This includes instructions for the proper set-
ting for the primary air adjuster. See the illus-
tration below for the location of the primary
air adjuster screw.
Making small adjustments to the primary air
setting will let you adjust the way the flames
look for your particular installation. See the
reference to primary air adjustment in the sec-
tions on page 20 that explains fine-tuning.
GAS CONNECTION
The GABO is shipped from the factory with a flexible gas connector that has a 1/2” NPT female connec-
tion. The gas supply piping should have a separate gas shut-off valve and a 1/8” NPT plugged tapping up-
stream of the valve. The GABO and its inlet regulator and main burner valve must be disconnected from
the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psi
(3.5kPa). The GABO must be isolated from the gas supply piping system by closing the main control valve
during any pressure testing of the gas supply system at test pressures equal to or less than 1/2 psi (3.5kPa).
After the gas supply has been connected, use a commercial gas leak detector or apply a soapy water solu-
tion to all the fittings to check for gas leaks. Never use a flame to test for leaks.

AIR INLET AND EXHAUST OUTLET RESTRICTORS
The GABO is equipped with externally adjustable restrictors for both the inlet air and the exhaust outlet.
This makes it possible to fine tune the direct vent system for the specific conditions of your installation.
The recommended settings are keyed to the specific details of your venting configuration.
To access the restrictor adjustment guide plates, you must first remove the front air louver from the stove.
To do this, first loosen the four decorative fasteners that secure the stove top. These do not have to be fully
removed but must be loose enough that the front of the top can be lifted up slightly. The louver assembly is
held in place by pins that are keyed to special slots in the sides of the stove. Grasp the louver assembly
firmly. Note: The louver is quite heavy so get a good grip on it. Pull the louver forward and lift the louver
up until it disengages from its retainer pins. The stove top may have to lifted slightly to allow room for the
louver to disengage from the stove. Having a second person lift the front edge of the top may be helpful
since the top is quite heavy. Once the louver disengages, slide it forward to remove it and set it aside. This
will now give you access to the restrictor guide plates and locking wingnuts.

You will now see the two guide plates. The guide plates have a pointer that corresponds to a number scale
for the air adjustment and letter scale for the exhaust adjustment. These are the letters and numbers that are
referenced in the venting charts on pages 10 and 11 and shown in detail in the examples shown on pages 8
and 9. To change the setting, loosen the guide plate locking wingnuts. Next rotate each guide plate to the
recommended setting for your installation shown in the appropriate venting chart for natural gas or for pro-
pane (LP) gas. Once the settings are correct, tighten the locking wingnuts.

Fine-Tuning
The recommended settings found in the vent charts on pages 10 & 11 and the default primary air settings have been
optimized based on extensive testing, however, additional adjustments may be required to accommodate specific in-
stallation circumstances. For example, a north wall installation may require slightly different settings than a south
wall.
Fine-tuning can be accomplished with the stove installed and operating. Please take care not to burn yourself on any
of the hot surfaces. Always wear gloves and other protective equipment.
The stove front and louver should still be removed at this point allowing the two adjuster mechanisms to be accessed.
The settings for each can be adjusted from the recommended settings while you are watching the fire in the stove.
It is important that the fine-tune adjustments are made only after the stove is thoroughly heated so allow the stove to
burn for at least 20-30 minutes at high fire
while observing the flame.
The type of adjustments that you might try are somewhat dependent on the type of fuel that is being used. When
burning natural gas, flames that are too short or too blue will be the most common observation. When burning pro-
pane, flames that are too long and too sooty will be most common. Each situation requires different actions.
If you are burning natural gas and observe that the flames are short and blue:
First, check the position of the primary burner air adjuster. The adjuster screw is located on the bottom of the fire-
box near the valve. For natural gas, the primary air adjuster should be in the fully-closed position. If it is not, loosen
the adjuster screw locknut and turn the adjuster screw in until it stops. If the appearance of the fire does not change,
you may need to adjust the air inlet restrictor. Be careful as the stove surfaces are HOT!
Loosen the air inlet restrictor indicator plate locking wingnut and move the setting up in ¼ increments. For example,
move the setting from 2 ¾ to 3. Tighten the locking wingnut and observe the flames. Repeat the process until the
flames become taller and more luminescent. However, no more than one full increment of adjustment should be
made. If the flames are still too short and blue, next adjust the exhaust baffle setting.
Loosen the exhaust baffle indicator plate locking wingnut and move the setting up in ¼ increments. For example,
move from a setting of D to a setting of D ¼. Repeat the process until the flames become taller and more lumines-
cent. However, no more than one full increment of adjustment should be made. If no change in the flame appearance
is noted after that, there may be an installation problem. Consult with a RAIS representative.
If you are burning propane and observe that the flames are tall and sooty:
First, check the position of the primary burner air adjuster. For propane, the primary air adjuster should be in the
fully-open position. If it is not, loosen the adjuster screw locknut and back out the adjuster screw until it stops.
If the appearance of the flame does not change, you may need to adjust the exhaust baffle. This can be done with the
stove operating but again, be careful as the stove surfaces are HOT!
Loosen the exhaust baffle indicator plate locking wingnut and move the setting down by ¼ increments. For example,
move from a setting of E ½ to a setting of E ¼. Tighten the locking wingnut and observe the flames. Repeat the proc-
ess until flame tips shorten and become lighter in color. However, no more than one full increment of adjustment
should be made. If the flames are still too tall and sooty, next adjust the air inlet restrictor setting.
Loosen the air inlet restrictor indicator plate locking wingnut and move the setting down in ¼ increments. For exam-
ple, move the setting from 2 ¾ to 2 ½. Tighten the locking wingnut and observe the flames. Repeat the process until
the flames become shorter and more lighter. However, no more than one full increment of adjustment should be
made. If no change in the flame appearance is noted after that, there may be an installation problem. Consult with a
RAIS representative.
Once all adjustments are made, make sure the air inlet and exhaust baffle adjuster plate locking wingnuts are tight.
If an adjustment was made to the primary burner air, tighten the locknut on the adjustment screw to lock in the new
setting. Shut off the stove and let it cool down.
Reinstall the Louver
Replace the air louver by aligning the slots on the louver end plates with the louver pins on the stove sides. You may
need to lift the top slightly to get “up-and-over” the pins. The louver will drop into place when in the proper position.
Tighten the four decorative top fasteners.
Reinstall the Stove Front
To reinstall the stove front, align the four attachment slots on the door edges with the pins on the stove sides. Push the
front in and down to its final position.
