These furnaces comply with requirements
embodied in the American National
Standard / National Standard of Canada
ANSI Z21.47·CSA-2.3 Gas Fired Central
Furnaces.
INSTALLER: Affix all manuals adjacent to the unit.
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.
This furnace may be paired with a cooling unit that uses R-32
refrigerant. If the cooling unit paired with this furnace does
not use R-32, the R-32 function in the furnace control board
needs to be turned off. please see the electrical and the R-32
sections for more details.
Refrigerant systems other than R-410A or R32 may
require an additional mitigation control board. Refer to
the installation manual of the indoor evaporator coil to
determine installation requirements for that supplier's
refrigerant detection system.
