1.  Disconnect power to the unit and shut off the gas sup-

ply.

2.  Remove window frame assembly.

3.  Carefully remove the logs & lava rock material.

4.  Remove the screws that are holding the burner hous-

ing 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.

  Gently lift off the pilot hood from the pilot. (Do not re-

move 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.

  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.

9.  SIT 820 NOVA Gas Control Valve (Fig. 52)

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. 53)

  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 conversion label supplied with conversion 

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 impingement on the 

logs, adjusting them if necessary. Check the manifold 

and supply pressures against the appliance specifica-

tions.
