CAUTION
The gas supply shall be shut OFF prior to discon-
necting the electrical power, before proceeding with
the conversion.
ATTENTION
Avant d’effecteur la conversion, coupez d’abord

IMPORTANT
The burner orifice provided in this kit are only for use at
elevations of 0 to 2,000 feet (610 M) in the USA and 0 to
4,500 feet (0-1372 M) in Canada. At higher elevations
the BTU input must be de-rated by 4% for every 1,000
feet (305 M) to maintain the proper ratio of gas to air. If
the installer must convert the unit to adjust for varying
altitudes, a deration information sticker must be filled
out by the installer and adhered to the appliance at the
time of the conversion. Contact your local gas supplier
for deration requirements for your area.
GAS CONVERSION INSTRUCTIONS
IMPORTANT NOTE: When installing gas components use pipe joint com-
pound or Teflon tape on all pipe fittings before installing (ensure pro-
pane resistant compounds are used, do not use pipe joint compounds
on flare fittings).
Step 1. TURN OFF THE GAS SUPPLY TO THE FIREPLACE and disconnect
power supply at the circuit breaker. Ensure fireplace is cold.
Step 2. Remove the burner pan from the fireplace to enable conversion
access. See installation manual if necessary.
Step 3. Disconnect the flex line at the main burner orifice. Then
remove the orifice and flared fitting from the orifice. Re-tape the
flared fitting with the new OAS-LP orifice per Table 2. Ensure to use
gas rated Teflon tape around the threads or pipe compound. Check for
leaks after conversion is complete.

Step 4. Locate the gas regulator on the opposite side of the valve box.
Using a regular size flat bladed screwdriver remove the aluminum cap and
washer from the regulator. See Figure 2.

Step 5. On the underneath side of the aluminum cap is a plastic stem. Us-
ing a 6mm wrench remove the stem, unscrew the stem (counter-clockwise
), turn it over and install the opposite end back into the cap. See
Figure 4.
GENERAL INFORMATION
Gas conversion kits are available to adapt the fireplace from the
use of one type of gas to the use of another. These kits contain all
the necessary components needed to complete the task including
labeling that must be affixed to ensure safe operation.

The gas type is determined with the arrow pointing at the aluminum cap
as seen in Figures 4 and 5.

CAUTION: ENSURE THE ALUMINUM CAP IS INSTALLED WITH
THE PLASTIC STEM SEATED COMPLETELY INTO THE CAP AND
THE METAL WASHER IS INSTALLED WITH THE ALUMINUM CAP.
Step 6. Secure the aluminum cap with a screwdriver.
Step 7. On the end of the burner pan where the pilot is located (see Figure
6), remove the four (4) 1/4” hex head screws securing the metal pilot box.
Two screws are located inside the burner pan, one on each side of the ig-
niter box screen mesh hood and the other two are securing a metal tab on
each side of the pilot box. See Figure 6 for screw locations.

Step 8. Once the pilot box is loosen and exposes the pilot assem-
bly then proceed to removing the pilot hood.
The pilot hood will lift straight up and out of the pilot assembly af-
ter removing the wire clip with a small screwdriver or needle-nose
pliers. See Figure 7.

Step 9. Insert a small flat bladed screwdriver into the slot of the brass
orifice inside the pilot assembly and turn clockwise until it stops
(approximately 2 full revolutions). See Figure 8.
Figure 8 - Shows Slot Inside Pilot Orifice
Once the orifice has been converted to LP then re-install the pilot
hood, ensure the clip is in place (if removed) and mount the metal
pilot box back into place ins the same manner you removed it from
the burner pan. See Figure 6 as a reference.

NOTE: Figures 51 and 52 provide a visual reference of the pilot
orifice from Natural gas to LP gas through the vent hole of the pilot
assembly.
Step 10. Look for the low rate set screw in the gas valve box.
There is a cutout (window) area that allows access to the low rate
set screw. Figure 10 shows the side view of the burner pan and a
close-up detail.
Figure 10 - Detailed Location of Low Rate Set Screw
Step 11. Remove the low rate set screw with a flat bladed screw-
driver turning the screw counter-clockwise . The set screw
has a rubber “O” ring on the outer portion of the screw, as a result
the screw will rotate only 3-4 revolutions and not unscrew any far-
ther.
NOTE: If you drop the low rate screw inside the valve area you can
retrieve it through the access door of the valve box.

Step 12. Remove the low rate set screw using a small pair of nee-
dle-nose pliers. Grab the outer edge of the screw and pull outward.
Step 13. Insert the correct new low rate screw from Table 3 with
the needle-nose pliers. Secure the new low rate set screw (clock-
wise ) with screwdriver until it is tight and now longer spins.
CAUTION: DO NOT REMOVE OR LOOSEN THE SMALL SET
SCREWS ON EACH SIDE OF THE V-WIRE. THESE ARE PRES-
SURE TEST PORTS. IF THESE ARE LOOSENED THEY MUST BE
RE-TIGHTENED TO ENSURE NO GAS LEAKS OCCUR.
Step 14. Ensure you test the burner pan after it is installed into the
fireplace. Turn on gas supply and test for gas leaks, using a gas leak
test solution—also known as bubble leak solution.
NOTE: Using a soapy water solution is an effective leak test
solution but it is not recommended, because the soap residue that
is left on the pipes/fittings can result in corrosion over time.
A. Light the fireplace (refer to the lighting instructions label on the
appliance).
B. Brush all joints and connections with the gas leak test solution
to check for leaks. If bubbles are formed, or gas odor is
detected, turn off the appliance. Either tighten or refasten the
leaking connection, and then retest as described above.
C. When the gas lines are tested and leak free, rinse off the leak
testing solution.
WARNING
Never use an open flame to check for leaks.
Step 15. Fill out the label “This fireplace has been converted to LP
gas” and affix it to the blank area on the rating plate.
Step 16. Conversion is now complete.

Figure 11 - Proper Flame Height
Proper Flame Height
Proper flame height (Figure 11) should be
at the top edge of glass windshield (peak-
ing above at times) while on HI setting.
The LO setting will be at least half of the
height of HI or maybe lower. There can be
a variance in flame height between Natural
gas and Liquid Propane (LP) gas models.
