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.
