Pipe Sizing - Propane Gas
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 for
propane conversion label. If there is a
conflict or doubt on the burner set up,
remove the gas valve and check for the
propane orifice, see Fig. 16, page 27.
Failure to ensure proper burner setup
could result in severe personal injury,
death or substantial property damage.
Contact the local propane gas supplier for rec-
ommended 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 conditions
to the burner. Must be verified during
start up and with all other gas appliances
operating within the building.
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.
The propane orifice requirements are:
PRESTIGE Excellence: 0.204” (5.2 mm)
