Fuel conversion instructions

The following  procedure must be carried out by a qualified technician. In this procedure, you will replace the 
current natural gas fuel mixer with the new propane fuel mixer.

To perform a fuel conversion:

 1.  Turn off the gas supply at the gas shut-off valve.

 2.  Change the gas fuel source.

 3.  Disconnect the electrical power.

 4.  Remove the front door cover.

 5.  Remove the top panel of the appliance to access the gas valve.

 6.  Remove the four (4) 5/16" hex bolts from the gas inlet to the mixing device. Carefully separate the two 

parts,  remove and retain the O-ring for re-assembly. (See 

 in image below).

 7.  Remove the four (4) ¼" hex bolts that connect the mixing device to the air filter box. The gasket should 

remain attached to the air filter box. (See 

 on image above).

 8.  Use a Hex key to remove the Six (6) 6 mm bolts connecting the mixing device to the fan. (See 

 in 

image above).  Carefully separate the two parts,  remove and retain the O-ring for re-assembly. 

 9.  Remove the propane mixing device.

 10.  When installing the new natural gas mixing device ensure that the O-ring is properly seated in the 

groove of the fan.

Caution

Failure to position the O-ring as indicated will result in a gas leak, and affect burner 
operation.

 11.  Re-assemble in the reverse order of steps provided.
