Gas Piping

PROPANE GAS

Pipe Sizing - Propane Gas

1. Contact the local propane gas supplier for

recommended sizing of piping, tanks and

100% lockup gas regulator.

P ropane Gas Supply Pre s s u r e Require m e n t s

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

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

i n j u ry, death or substantial pro p e rt y

damage.

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.
