Pipe Sizing - Propane Gas

1.Contact the local propane gas supplier for recommended sizing of piping, tanks and 100% lockup gas regulator.

Propane Gas Supply Pressure Requirements

1.Adjust the propane supply regulator pro- vided by the gas supplier for 13”w.c. max- imum pressure

2.Pressure required at the gas valve inlet sup- ply pressure port:

-Maximum 13”w.c. at flow or no flow conditions to the burner

-Minimum 5”w.c. during flow condi- tions to the burner. Must be verified during start up and with all gas appli- ances operating

WARNING

DO NOT adjust or attempt to measure gas valve outlet pressure. The gas valve is factory-set for the correct outlet pres- sure. This setting is suitable for natural gas and propane and requires no field adjustment. Attempts by the installer to adjust or measure the gas valve outlet pressure could result in damage to the valve, causing potential severe personal injury, death or substantial property damage.

WARNING

Prior to start up ensure the unit is set to fire propane. Check the rating label for the type of fuel. Check the gas valve and air inlet for propane conversion labels. If there is a conflict or doubt on the burner set up, remove the gas valve and check for the propane orifice. Failure to ensure proper burner setup could result in severe personal injury, death or sub- stantial property damage.
