D. High Altitude Installations
U.L. listed gas appliances are tested and approved without
requiring changes for elevations from 0 to 2000 ft in the USA
and Canada.
When installing this appliance at an elevation above 2000 ft,
it may be necessary to decrease the input rating by chang-
ing the existing burner orifi ce to a smaller size. Input rate
should be reduced by 4% for each 1000 ft above a 2000 ft
elevation in the U.S.A., or 10% for elevations between 2000
and 4500 ft in Canada. If the heating value of the gas has
been reduced, these rules do not apply. To identify the prop-
er orifi ce size, check with the local gas utility.
If installing this appliance at an elevation above 4500 ft (in
Canada), check with local authorities.
E. LP Gas Supply
• The pressure regulator and hose assembly supplied
with LP models must be used. Replacement pressure
regulators and hose assemblies must be those specifi ed
in this manual.
• The LP gas supply cylinder used with LP models must
be constructed and marked in accordance with the
specifi cations for LP gas cylinders of the U.S. Department
of Transportation (DOT).
• Cylinders must be stored outdoors in a well ventilated
area out of the reach of children. Disconnected cylinders
must have threaded valve plugs tightly installed and must
not be stored in a building, garage or any other enclosed
area.
• Storage of this appliance indoors is permissible only if it
has been disconnected from its fuel supply (natural gas
line or LP gas cylinder).
• The LP gas cylinder supply system must be arranged for
vapor withdrawal.
• The LP gas cylinder used must include a collar to protect
the cylinder valve.
• When an LP model is not in use, the LP gas must be turned
off at the supply cylinder.
