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.
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.
Prior to star
t up, ensure the appliance is
set to fire propane. Check the rating
label for the type of fuel. Check the gas
valve for propane conversion label. If
there is a conflict or doubt on the burner
set up, remove the gas valve and check
for proper propane orifice. See Fig. 12
and Table 2. Failure to ensure proper
burner setup could result in severe per-
sonal injury, death or substantial prop-
erty damage.
