ATTENTION INSTALLING PERSONNEL

As a professional installer you have an obligation to know the product better than the customer.  This includes all safety

precautions and related items.

Prior to actual installation, thoroughly familiarize yourself with this Instruction Manual. Pay special attention to all safety

warnings. Often during installation or repair it is possible to place yourself in a position which is more hazardous than

when the unit is in operation.

Remember, it is your responsibility to install the product safely and to know it well enough to be able to instruct a customer

in its safe use.

Safety is a matter of common sense...a matter of thinking before acting. Most dealers have a list of specific good safety

practices...follow them.

The precautions listed in this Installation Manual are intended as supplemental to existing practices.   However, if there is

a direct conflict between existing practices and the content of this manual, the precautions listed here take precedence.

(Type FSP CATEGORY IV Direct or Non Direct Vent Air Furnace)

RECOGNIZE THIS SYMBOL AS A SAFETY PRECAUTION.

These furnaces comply with requirements
embodied in the American National Standard
/ National Standard of Canada ANSI
Z21.47·CSA-2.3 Gas Fired Central Fur-
naces.
