The conversion of this appliance from one 
gas to another must be carried out by an 
authorized service provider.

ply.

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.
7.  SIT top Convertible Pilot 
  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.

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. 
9. 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.
10. 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.
Fuel Conversion Instructions
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.
