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 feet, it may be necessary to decrease the

input rating by changing the existing burner oriﬁ ce

to a smaller size. Input rate should be reduced by

4% for each 1000 feet above a 2000 foot elevation

in the U.S.A., or 10% for elevations between 2000

and 4500 feet in Canada. If the heating value of the

gas has been reduced, these rules do not apply. To

identify the proper oriﬁ ce size, check with the local

gas utility.

If installing this appliance at an elevation above 4500

feet (in Canada), check with local authorities.
