INSTALLING GAS CONVERSION KITS
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
l’alimentation en gaz, ensuite, coupez l’alimentation
electrique.
1. Disconnect power supply at the circuit breaker. Ensure fire-
place is cold.
2. TURN OFF THE GAS SUPPLY TO THE FIREPLACE AND DIS-
CONNECT THE FLEX LINE AT THE ELBOW FITTING ON THE
REGULATOR INLET (SEE FIGURE 3).
3. Remove the barrier, facade, and glass door per instruction in the
Installation and Operation Manual.
4. Open the lower control compartment door.
5. (Traditional Models) Remove the logs per instruction in the
Installation and Operation Manual. If necessary, remove the log
grate. Exercise care so as not to break the logs.
6. (Contemporary Models) Remove the glass media from firebox.
7. Perform the following conversion instructions:
Figure 1
Figure 2
Step 2. Remove the low-rate orifice from the valve and replace with the
orifice supplied in kit. See Figure 2.
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. Remove Burner assembly and replace the main burner orifice sup-
plied in this kit. Refer to Table 5 on Page 5 for verification of proper main
burner orifice size supplied in kit.

the burner assembly into its position and secure the trapezoidal plate with
the two screws previously removed.
Step 8. Reinstall the baffle with the two baffle securing screws.

WARNING
Never use an open flame to check for leaks.
Step 9. Reinstall the log set (Traditional Models) or glass media (Contem-
porary Models). See log set installation or glass media installation and
door Assembly installation in the installation and operation manual.
Step 10. Reinstall the glass door.
Step 11. 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 in the control
compartment).
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.

Step 12. Adjust the burner air shutter per instructions in the Installation
and Operation manuals and Table 2 and Figures 6 and 7.
CAUTION: The air shutter should never be set so as to make the tips of
the flames sooty or create sooting on the viewing glass, logs, or media.
If soot begins to form after burning, the air shutter should be opened
gradually until the sooting condition stops. Gas quality and gas pres-
sure may vary, which can affect the burning characteristics of the ap-
pliance.
Figure 8 - Pilot Flame Appearance
Step 13. Relight the main burner. The lighting instructions can be found on
the lighting label in the control compartment. Verify proper burner ignition
and operation (Figure 7).
Inspect the pilot system for proper flame. The pilot flame should engulf the
flame sensor (Figure 8).
Using a manometer, test the inlet and manifold gas pressures (Tables 3–4,
Page 6). The inlet pressure is tested at elbow fitting removable plug and
the outlet pressure is tested at gas valve outlet test port (see Figures 12
and 13 on Page 7).
Always test pressures with the valve regulator control at the highest
setting.
