CONVERTING THE APPLIANCE FROM LP TO
NATURAL GAS OR NATURAL GAS TO LP
The conversion of this appliance from one gas to
another must be carried out by an authorized
service provider.
1. Disconnect power to unit and shut off 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 assembly 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. 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 thermocou-
ple, thermopile or igniter.
9. SIT 820 NOVA Gas Control Valve (Fig. 47)
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
positioned and install the new Hi/Lo pressure
regulator 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. 48)
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 not over-tighten the screw, it must be finger
tight.
d) Refit the regulator cap.
e) Mount the conversion label supplied with
conversion screw to the valve in a visible posi-
tion.
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 manifold and supply pressures against
appliance specifications.
The procedure for converting from one
gas to another is the same regadless of
the initial gas used. The only variation is
in the orifice-sizes and component part
numbers. Your authorized service
provider will ensure the correct parts
are used.
