Combustible Materials
The ductwork should be appropriately sized to the capacity
of the furnace to ensure its proper airflow rating. For
installations above 2,000 ft., the furnace should have a
sea level input rating large enough that it will meet the
heating load after deration for altitude.

Installation in a Garage

wARNING:
Do not place combustible materials on or against
the furnace cabinet or within 6 inches of the
vent pipe. Do not place combustible materials,
including gasoline or any other flammable
vapors and liquids,in the vicinity of the furnace.
This gas-fired furnace may be installed in a residential
garage with the provision that the burners and igniter
are located no less than 18 inches (457mm) above the
floor. The furnace must be located or protected to prevent
physical damage by vehicles.

Operation of Furnace During Construction

CAUTION:
Failure to follow these instructions will void the
factory warranty and may significantly reduce
the life or the performance of the furnace, and/
or result in other unsafe conditions. It is the
responsibility of the installing contractor to
insure these provisions are met.
Operating gas furnaces in construction environments can
cause a variety of problems with the furnace. Proper use
of commercial portable space heating equipment during
construction is recommended. This gas furnace may be
used during construction if it is not in violation of any
applicable codes and the following criteria are met:
• The installation must meet all applicable codes. The
furnace must be permanently installed according to
the instructions with the furnace including electrical
supply, gas supply, duct work and venting. The furnace
must be controlled by a thermostat properly installed
according to the instructions supplied with the furnace
and thermostat. The installation must include a properly
installed filter in the return air system with no by-pass
air. The filter must be inspected frequently and replaced
when necessary.
• Combustion air must be supplied from outside the
structure and located such that dust and gases
from construction activity are not introduced into the
combustion system.
• Before occupying the structure: The filter must be
replaced or cleaned, the duct work must be inspected
and cleaned of any construction debris, and the furnace
must be cleaned and/or repaired if found to be dirty,
damaged, or malfunctioning in any way by a qualified
HVAC technician. The furnace shall be inspected and
approved by applicable local authority even if this
requires redundant inspections.
• Serial numbers for furnaces used during construction
must be submitted in writing (fax and email also
acceptable). This information will be used to track the
long-term affects of the use during construction on
furnaces. Proof of this submittal shall be available for
the final inspection of the furnace prior to occupancy.
• This furnace is designed to operate with return air
temperatures in ranges normally found in occupied
residences, including setbacks. Minimum continuous
return temperature must not fall below 60° F (15° C).
Occasionally a temporary return temperature of 55° F
(12° C) is acceptable. However, operation with a return
temperature below 55° F (12° C) is not allowed.
