Fuel Conversion Instructions

The conversion of this appliance from one
gas to another must be carried out by a
qualified service technician.
1. Disconnect power to unit and shut off the gas supply.
2. Remove the glass (Refer to "Glass Removal" Sec-
tion.)
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. On this model you may
need to loosen the pilot bracket retaining screw/nut
and tilt pilot and bracket assembly to gain sufficient
clearance to remove the burner housing.
6. Remove front and rear orifice and replace with ori-
fice supplied in the conversion kit.
7. SIT top Convertible Pilot
Gently lift off pilot hood from the pilot. (Do not
remove the spring clip holding the hood in place).
Using a size 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.
PSE Pilot
Using a suitable wrench on 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, thermopile or
igniter.
8. SIT 820 NOVA Gas Control Valve (Fig. 11)
a) Using a Torx T20 or slotted screwdriver, remove
and save 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 regulator
to 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. 12)

quired gas application by the installation of a color
coded "conversion screw".

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.
