GAS PRESSURE
The gas pressure must remain between 4 inches w.c. (Natural), 8
inches w.c. (Propane (LP)) minimum and 14 inches w.c. (Natural
and Propane (LP)) maximum during stand-by (static) mode and
while in operating (dynamic) mode. If an in-line regulator is used,
it must be a minimum of 10 feet from the XP water heater. It is
very important that the gas line is properly purged by the gas
supplier or utility company. Failure to properly purge the lines or
improper line sizing, will result in ignition failure.
The problem is especially noticeable in NEW Propane (LP)
installations and also in empty tank situations. This can also
occur when a utility company shuts off service to an area to
provide maintenance to their lines.
GAS VALVE REPLACEMENT
The gas valve MUST NOT be replaced with a conventional gas
valve under any circumstances. As an additional safety feature,
this gas valve has a flanged connection to the venturi and blower.
Failure to follow all precautions could result in fire, explosion, or
death!
DO NOT adjust gas valve outlet pressure. The gas valve is
factory-set for the correct outlet pressure. This setting is suitable
for natural gas and propane, requiring no field adjustment.
Attempting to alter the gas valve outlet pressure could result in
damage to the valve, causing potential severe personal injury,
death, or substantial property damage.
