Propane Gas

6.3.1 Pipe Sizing

WARNING
• The unit was shipped with a propane con-
version kit which is located on the top of
the unit in the instructions packet. This
kit includes all the necessary parts and in-
struction to perform the conversion from
natural to propane gas. If this conversion
kit is missing, please contact ACV-Trian-
gle Tube Technical Support for missing
kit before installing unit.
• 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. 14 on page 28.
• Failure to ensure proper burner setup can
result in substantial property damage,
serious injury, or death.
Contact the local propane gas supplier for recommend-
ed sizing of piping, tanks and 100% lockup gas regula-
tor.

6.3.2 Supply Pressure Requirements

1. Adjust the propane supply regulator provided by
the gas supplier for 13"w.c. maximum pressure
2. Pressure required at the gas valve inlet supply pres-
sure 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.
WARNING
DO NOT adjust or attempt to measure gas
valve outlet pressure. The gas valve is facto-
ry-set for the correct outlet pressure. This set-
ting 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 can result in damage to
the valve, causing substantial property dam-
age, serious injury, or death.
NOTICE
The propane orifice requirements are:
• PRESTIGE Excellence 110: 0.175" (4.45 mm)
•
WARNING
The propane gas orifice must never be modified
or replaced with a different size orifice. Failure
to use the required propane gas orifice can re-
sult in substantial property damage, serious in-
jury, or death.
