As an owner of a new furnace you need
to know the following information:
If your home is located at an elevation above 2,000 feet, the burner orifice in your furnace will need
to be derated. Please contact the nearest authorized Service Center to have this procedure
performed properly.
Your dealer or gas company may have already applied the proper deration for your unit. If so, they
should be able to advise you as such. If not, you need to have the deration made to insure continued
use of your furnace. Not having the unit derated properly will eventually render the furnace
inoperable.
Deration of the orifice for furnaces installed in homes at elevations above 2,000 feet is not covered
by the warranty. This procedure is considered a part of the installation process and is required to
make the furnace operate properly.
These furnaces are shipped from the factory with a natural gas orifice. If you will be operating this
furnace on LP (liquid propane gas), it will also be necessary to have the furnace converted. The
correct LP orifice is supplied with the furnace to allow operation at elevations below 2,000 feet. If
the furnace will be operating on LP gas at elevations above 2,000 feet, the orifice supplied will be
too large to allow proper operation. You should contact your LP supplier for assistance in getting
the derated orifice installed.
We hope you follow these instructions and enjoy many years of trouble free service. If you have any
questions, please feel free to contact the technical assistance hot line at 316/832---6450.
