GAS SELECTION

This appliance is factory 

preset for propane/LP gas. 

No changes are required for 

connecting to propane/LP.

 

Only a qualified installer or service 

technician can perform gas selec-

tion and connecting to gas supply.

 CAUTION: Two gas line in-

stallations at the same time are 

prohibited.

 CAUTION: To avoid gas leak-

age for the gas not being used at 

the inlet of regulator, a qualified 

installer or service technician 

must use supplied cap.
You will notice a color coded 

plunger on the inside of the regu-

lator. This is normal. When the in-

let connection fitting is inserted 

and tightened, this plunger will 

be  pushed  back  by  the  fitting 

making  all  of  the  adjustments 

for the gas being supplied. DO 

NOT REMOVE THE PLUNGER. 

The regulator will not work.

The inlet regulator is color coded 

for identification of the correct 

gas type. Blue is for propane (LP 

gas) and yellow is for natural gas.
