Listing and Code Approvals
C. High Altitude Installations
U.L. Listed gas appliances are tested and approved with-
out 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 rat-
ing 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.
