D. High Altitude Installations
U.L. Listed gas appliances are tested and approved without requiring changes for elevations from 0 to 2000 feet in the U.S.A. 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.
WARNING
Do NOT use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water.
E. Non-Combustible Materials
