Fuel Conversion Instructions

The conversion of this appliance from one
gas to another must be carried out by an
authorized service provider.
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 clear-
ance to remove the burner housing assembly.
6. Remove the main burner orifice and replace it with
the orifice supplied in the conversion kit.
7. SIT top Convertible Pilot
Gently lift off the pilot hood from the pilot. (Do not
remove the spring clip holding the hood in place).
Using a 5/32" 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. PSE Pilot
Using a suitable wrench on the hexagonal body
unscrew the pilot hood assembly from the pilot, do
not twist the hood itself. Remove the orifice and
replace it with the new orifice supplied in the kit. Refit
the pilot hood assembly. Do not over-tighten the pilot
hood. The hood must return to its original alignment.
Take care not to damage the thermocouple, thermo-
pile or igniter.
9. SIT 820 NOVA Gas Control Valve (Fig. 49)
a. Using a Torx T20 or slotted screwdriver, remove
and save the three pressure regulator mounting
screws (A), pressure regulator tower (B) and
diaphram (C).
b. Ensure the rubber gasket (D) is properly posi-
tioned and install the new HI/LO pressure regula-
tor to the valve using the new screws (E) supplied
with the kit. Tighten screws securely. (Reference
torque - 25 in.LB)
c. Install the enclosed identification label (F) to the
valve body where it can be easily seen.
Honeywell Gas Control Valve (Fig. 50)
The Honeywell valve fitted to this unit is suitable for
use with LP or Natural Gas. It is converted to the
required gas application by the installation 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
30
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.
10. 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.
11. 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 appli-
ance specifications.
