Shutoff Valve
Note:
The appliance and its manual shutoff valve must
be disconnected from the gas supply piping system dur-
ing any pressure testing of that system at test pressures
in excess of 1/2 psi (3.5 kPa). The appliance must be
isolated from the gas supply piping system by closing its
manual shutoff valve during any pressure testing of the
gas supply piping system at test pressures equal to or
less than 1/2 psi (3.5 kPa).

TABLE 2
1. HIGH ALTITUDE INSTALLATION
For U.S. installation, appliances are tested and
approved for elevations from 0-2000 feet. When
installing this appliance at an elevation above 2000
feet, National Fuel Gas Codes require a decrease of
the input rating by changing the existing burner orifice
to a smaller size. Input should be reduced 4% for each
1000 feet above sea level. Check with the local gas
utility for proper orifice size identification. Orifices are
available from your distributor.
For Canada, appliances are certified for elevations from
0-4500 feet. When installing this appliance at an
elevation between 0-4500 feet in Canada, the input
rating does not need to be reduced. When installing
this appliance at an elevation above 4500 feet in
Canada, check with local authorities.
2. GAS LINE CONNECTION
The appliance is provided with a stainless steel flexible
connector and manual shutoff valve. See Figure 12.
The incoming gas line should be piped into the valve
compartment and connected to the 1/2 FIP connection
provided on the manual shutoff valve. See Figure 13.
All connections must be tightened and checked for
leaks with a soap and water solution or leak detector.
Bleed the gas line to extract any air that may have
been trapped inside the pipe.
