STEP 9. Remove the main burner orice, at the rear of the unit, with a ” deep socket.

STEP 10. Install the new orice supplied. Be sure to put a bead of pipe thread sealant or approved Teon tape on

the orice before installing into the burner assembly.

STEP 11. Re-install burner tray, log set and door. Pay special attention when installing the burner that the venturi

adjustment rod is properly installed into the venturi adjustment piece welded to the burner venturi tube.

Also refer to “Installing Log Set and Embers.”

STEP 12. Reconnect the gas line to the unit. Do a leak check using soap and water solution or an approved method

on the gas supply line.

STEP 13. Re-light the appliance to ensure proper operation and proper ame appearance.

STEP 14. MAKE SURE that the sticker provided by S.I.T is installed to signify that this valve has been converted to

a different type of fuel. Also make sure that the rating plate has a conversion label to show that this unit

has been converted to a different fuel type.

A VISUAL CHECK OF THE REGULATOR KNOB IS NECESSARY TO DETERMINE WHETHER OR NOT THE REGULATOR

IS THE CORRECT PART. A 50% TURN DOWN REGULATOR WILL HAVE ONLY ONE CORNER ON THE KNOB.

AIR SHUTTER:

The air shutter is controlled with the primary air adjustment rod located behind the gas valve shown in Figure 41.

The air shutter allows the amount of air coming into the replace to be adjusted in order to accommodate different

climates and venting arrangements. Start the pilot and then the burner. Make sure the pilot ame is burning

normally and none of the burner ports are plugged. Let the replace burn for roughly fteen minutes and then

examine the ames, compare the ames to Figure 50.

The ideal ame will be blue at the base and light orange above. The ames should be of medium height. If the

ames look like this, no venturi adjustment is needed. If the ames are fairly short and mostly blue, the replace

is getting too much air. Therefore, the air shutter should be closed slightly until the correct ames are achieved.

Flames that are very orange, with tall, dark, stringy tips, are not getting enough air. Open the venturi until the

ames clean up. If the venturi is opened, or closed all the way, and the correct ames cannot be attained, turn off

the gas and contact the dealer.

Warning: Incorrect venturi adjustment may lead to improper combustion, which is a safety hazard. Contact the

dealer if there is any concern about the venturi adjustment.
