For detailed information, refer to the complete installation and owner’s manual.

• Check supply pressure and local code
requirements before proceeding with
installation.

• Consider pipe fittings when
determining gas pipe sizing.

• Larger pipe size can be used if
required by local code.

• It is critical that the incoming gas
supply pressure at the heater is
within the maximum and minimum
pressure requirements. If the range
of acceptable supply pressure is not
provided, the gas supply system to
the heater must be modified to meet
pressure requirements.

installed in an accessible location
within six (6) feet of the heater.

• Do not use CSST or any flexible
gas piping.

GAS LINE SIZING

* Numbers are for natural gas (0.65 Sp. Gr.) based on 1/2 inch (3.45 kPa) water column pressure drop. Check

supply pressure with a manometer, and local code requirements for variations. For LP gas, reduce pipe
diameter by one size, but maintain a minimum 3/4 inch diameter.

For specific requirements:
(1) Natural gas heaters, refer to NFPA® 54.
(2) Propane heaters, refer to NFPA 58.

GAS PRESSURE TEST

• Check the gas supply pressure while
the heater is operating.

• Any adjustments or readings made
while the heater is off will result in poor
performance and other problems.

• Connect a differential manometer
to the supply pressure port on the

gas valve.

• If the gas supply pressure does
not meet requirements (see table,
right), check for a restrictive fitting,
undersized gas meter, or undersized
pipe between the meter and the heater.

• Minimum inlet supply pressure must
be maintained during heater operation
while there is a full demand on the gas
delivery system.
