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 loos-
en 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.  For Model 36LDVT ONLY: Remove the rear log 
support and relocate the two (2) screws that locate 
the rear log as shown in Figure 45.
9.  PSE Pilot
  Using a suitable wrench on the hexagonal body, un-
screw 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.
10.SIT 820 NOVA Gas Control Valve (Fig. 46)
  a. Using a Torx T20 or slotted screwdriver, remove 
and save the three pressure regulator mount-
ing screws (A), pressure regulator tower (B) and 
diaphram (C). 
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. 
Your authorized service provider will 
ensure the correct parts are used.

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.
  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. 47)
  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 con-
version screw to the valve in a visible position.
11. Reassemble the fireplace in the reverse order, ex-
cept for the window frame assembly. Leave this off 
until after the unit has been checked for leaks and 
the gas supply has been bled.
