ATTENTION INSTALLING PERSONNEL

RECOGNIZE THIS SYMBOL AS A SAFETY PRECAUTION.

Installer:  Affix all manuals adjacent to the unit.

These furnaces comply with requirements em-
bodied in the American National Standard / Na-
tional Standard of Canada ANSI Z21.47·CSA-
2.3 Gas Fired Central Furnaces.

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.

NOTE

: Please contact your distributor or our website listed below

for the applicable Specification Sheet referred to in this manual.
