Gas Supply Pressure Requirements

Inlet and manifold gas supply pressure require-
ments for these appliances are listed in Tables
2 and 3.
Inlet Gas Supply Pressure (all models)
Fuel # Minimum
5.0" WC
Natural Gas
(1.24 kPa)
11.0" WC
Propane
(2.74 kPa)

Manifold Gas Supply Pressure (all models)
Fuel # Low
Natural (Lo) 1.6" WC
Gas (0.4 kPa)
(Lo) 6.3" WC
Propane
(1.57 kPa)
Table 3
Test gauge connections are provided on
the front of the electronic gas control valve
(identified IN for the inlet and OUT for the
manifold side).
The control valves have a 3/8" (10 mm) NPT
thread inlet and outlet side of the valve. Refer
to Figure 1.
Propane tanks are at pressures that will cause
damage to valve components. Verify that the
tanks have step-down regulators to reduce the
pressure to safe levels.
These appliances must not be connected to a
chimney or flue serving a separate solid fuel
burning appliance.

These appliances must be isolated from
the gas supply piping system (by closing
their individual manual shut-off valve)
during any pressure testing of the gas
supply piping system at test pressures
equal to or less than 1/2 psig (3.5 kPa).
Maximum
10.5" WC
These appliances and their individual
(2.61 kPa)
shut-off valves must be disconnected
13.0" WC
(3.23 kPa) from the gas supply piping system
during any pressure testing of that
system at pressures greater than 1/2
psig (3.5 kPa).

These appliances are tested and approved
for installation at elevations of 0–4500 feet
(0– 1372 meters) above sea level using the
standard burner orifice sizes (marked with an
asterisk [*] in Table 4 ). For elevations above
4500 feet, contact your gas supplier or qualified
service technician.
Deration
At higher elevations, the amount of BTU fuel
value delivered must be reduced by either:
• using gas that has been derated by the gas
company; or
• changing the burner orifice to a smaller size
as regulated by the local authorities having
jurisdiction and by the (USA) National Fuel
Gas Code NFPA 54/ANSI Z223.1 - latest
edition or, in Canada, the CAN/CSA-B149.1
codes - latest edition.
Install the appliance according to the regulations
of the local authorities having jurisdiction and,
in the USA, the National Fuel Gas Code NFPA
