High Altitude Conversions
For high altitude installations in the United States, refer to the
American Gas Association guidelines for the gas designed
appliances derating method. For elevations above 2,000 ft
(610 m), input ratings are to be reduced by 4% for each 1,000
ft (305 m) above sea level.
When the appliance is installed at elevations above 4,500 ft
(1,372 m), the certified high altitude rating shall be reduced at
the rate of 4% for each additional 1,000 ft (305 m). Refer also
to CSA-B149.1 Natural Gas and Propane Installation Code,
local authorities, or codes which have jurisdiction in your area
regarding the derate guidelines.
CAUTION: The gas supply shall be shut off prior to
disconnecting the electrical power, before proceeding with
the conversion.
A. Prepare the Fireplace
Step 1: Remove the safety barrier and glass frame assembly.
Step 2: Remove the log set.
Step 3: Remove the burner assembly.
Refer to the installation manual for more information.
B. Replace Burner Orifice
Step 1: Remove the existing orifice cap.
Step 2: Replace with the orifice cap included with this kit.
Tighten cap securely. The sizes are stamped on the
orifices.

C. Convert Pilot Assembly
Step 1: Remove the spring holding the pilot hood in place. Then
pull the pilot hood directly up from the pilot bracket.
Step 2: Insert a
key-way, then turn counter-clockwise to remove the
injector from the injector journal.
Step 3: Install the injector from the kit into injector journal.
Place the hex key into the end of the injector and turn
clockwise until a recommended torque of 9 lb-in. (1.0
Nm) is achieved. Propane injectors have a groove
around the top, NG injectors do not. The size is
stamped on the pilot injector.
Step 4: Align the tab on the base of the pilot hood with the slot
in side of pilot journal, then push the hood directly down
into the pilot bracket. The pilot hood must sit square for
proper operation.
Step 5: Push the previously removed spring onto the barrel seat.

Follow the stepper motor pressure regulator instruction sheet
included with this conversion kit to convert the gas valve.
E. Complete the Conversion
Step 1: Adjust the venturi. Loosen the screw, then adjust the
cap to the correct setting. Re-tighten the screw. See
Table 2.
Step 2: Reinstall all components previously removed. Refer to
