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 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).
•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.
