Installation in a Garage
WARNING:
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.
This furnace is Design Certified in the U.S. and Canada
by CSA International for the minimum clearances to
combustible materials. NOTE: The furnace is listed for
installation on combustible or non-combustible flooring.
However, wood is the only combustible flooring allowed
for installation. Downflow models must use the appropriate
subase kit when installing over a wood floor. To obtain
model number and specific clearance information, refer
to the furnace rating plate, located inside of the furnace
cabinet.
Access for positioning and servicing the unit must be
considered when locating unit. The need to provide
clearance for access to panels or doors may require
clearance distances over and above the requirements.
See Figure 1 for minimum clearance requirements.
CAUTION:
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 mustmeetallapplicablecodes.The
furnace must be permanently installed according to
the instructions supplied 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.
• Provisions must be made to insure that condensate
does not freeze in the furnace or condensate drain
lines during operation and during idle times; for
example, overnight if turned off.
• Before occupying the structure: The lter 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.
• Serialnumbersforfurnacesusedduringconstruction
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 be 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.
