D. High Altitude Installations
Appliances are tested and approved without requiring chang-
es 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 orifice 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 orifice 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 specified
in this manual.
• The LP gas supply cylinder used with LP models must
be constructed and marked in accordance with the
specifications for LP gas cylinders of the U.S. Department
of Transportation (DOT). A minimum 20 lb. cylinder is
recommended.
• 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.
