HIGH ALTITUDE INSTALLATIONS
Intertek Testing Lab listed gas appliances are tested and
approved without requiring changes for elevations from 0
to 2000 feet in the U.S.A. and 0 to 4500 feet in 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. 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 in Canada at an elevation above
4500 feet, check with local authorities.
