It should not befactored as primary heat in residential heating calculations.C. High Altitude InstallationsU.L. Listed gas appliances are tested and approved with-out requiring changes for elevations from 0 to 2000 feet inthe U.S.A. and Canada.When installing this appliance at an elevation above 2000feet, it may be necessary to decrease the input ratingby changing the existing burner orifice to a smaller size.Input rate should be reduced by 4% for each 1000 feetabove a 2000 foot elevation in the U.S.A., or 10% for el-evations between 2000 and 4500 feet in Canada. If theheating value of the gas has been reduced, these rulesdo not apply. To identify the proper orifice size, check withthe local gas utility.If installing this appliance at an elevation above 4500 feet(in Canada), check with local authorities.
