High Altitude Installations
U.L. Listed gas appliances are tested and approved without requiring changes
for elevations from 0 to 2,000 feet in the U. S. A. and in Canada.
When installing this appliance at an elevation above 2,000 feet, it may be necessary
to decrease the input rating by changing the existing burner orifice 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 orifice size, check with the local gas utility.
If installing this appliance at an elevation above 4,500 feet (in Canada), check
with local authorities.
Consult your local gas utility for assistance in determining the proper orifice for
your location.
