LP Conversion Procedure
1. Disconnect power to the unit and shut off the gas
supply.
2. Remove window frame assembly.
3. Carefully remove the logs & lava rock material.
4. Remove the screws that are holding the burner
housing in place.
5. Remove the burner housing assembly. Depending
on the model of the appliance you may have to
loosen the pilot bracket retaining screw/nut to allow
the pilot and bracket assembly to tilt and give
enough clearance to remove the burner housing
assembly.
6. Remove the main burner orifice and replace it with
the orifice supplied in the conversion kit.
7. Gently lift off the pilot hood from the pilot. (Do not
remove the spring clip holding the hood in place).
Using a correctly sized Allen key unscrew the
exposed orifice. Insert the new orifice supplied in
the kit, do not over tighten the orifice. Replace the
pilot hood ensuring the index tab aligns with the
notch on the hood.
8. The Honeywell valve (Fig. 41) fitted to this unit is
suitable for use with LP or Natural Gas. It is con-
verted to the required gas application by the instal-
lation of a color coded “conversion screw”.
a) Using a suitable small screwdriver lift out the
central regulator cap from the “Hi/Lo” knob on
the valve.
b) Unscrew the exposed conversion screw.
c) Insert the new color coded conversion screw. Do
not over-tighten the screw, it must be finger tight.
d) Refit the regulator cap.
e) Mount conversion label supplied with conver-
sion screw to valve in a visible position.
Fuel Conversion Instructions
8. Reassemble the fireplace in the reverse order,
except for the window frame assembly. Leave this
off until after the unit has been checked for leaks
and the gas supply has been bled.
9. After bleeding the gas line and checking for leaks
with a soap solution, replace the window frame
assembly. Fire up the unit, check for flame impinge-
ment on the logs, adjusting them if necessary.
Check the manifold and supply pressures against
the appliance specifications.
Air Shutter Setting
The air shutter is factory set at 50% open for natural
gas (or if converting back to natural gas).
The air shutter setting for propane gas is fully open
when field converted.

The procedure for converting from one
gas to another is the same regardless of
the initial gas used. The only variation is
in the orifice-sizes and component part
numbers.
NOTE: When converting this unit to LP, keep all parts
removed in case you need to convert back to natural
gas.
