4.0 LOCATION OF UNIT
4.1 GENERAL
GUIDELINES
4.2 OTHER
CONSIDERATIONS
H8.1.3
1. Select a location where the exhaust and combustion air piping can be routed between the furnace and
their terminations with a minimum of lengths and
fi
ttings. Be sure to check that the proposed termination
location will meet code requirements with respect to location and minimum clearances.
(See venting
section for minimum and maximum limits.)
2. Select a location as near as possible to the existing or proposed duct system.
3. The furnace location must have provisions for condensate drainage. If a suitable drain is unavailable near
the furnace, a condensate pump must be used. The condensate pump drain tubing must not terminate
outdoors; similar to some air conditioning condensate installations. Be sure to select a condensate pump
that has been approved for furnace condensate applications.
4. The furnace location must permit access for servicing and be within the clearance to combustibles
guidelines as marked on the appliance rating plate.
5. The furnace must be installed on a level surface. It is recommended that the rear of the furnace be
elevated 1/4” (6mm) higher than the front to facilitate proper condensate drainage.
6. If the furnace is being installed so that the return air will enter through the bottom, the perimeter of the
furnace must be properly supported.
7. In right venting con
fi
guration, furnace must drain on the left side.
H8.2
1. If the furnace is to be located in an area where the combustion air is laden with chemical compounds such
as bromine, chlorine or
fl
uorine, as may be found in swimming pool chemicals, laundry detergents, etc.,
use outdoor air for combustion
. These compounds when exposed to
fl
ame, form acids which attack the
heat exchanger and other components.
Exposure to the following substances in the combustion air supply (but not limited to the following) will also
require OUTDOOR AIR for combustion:
•
Aerosols, particularly CFC based or propelled aerosols
• Air
fresheners
•
“Airplane Glue” and similar adhesives and cements
•
Ammonia, as commonly found in permanent wave solutions used in hair dressing salons
•
Anti-static fabric softeners used in clothes dryers
• Carbon
tetrachloride
•
Chlorinated cleaners and waxes
•
Chlorine and bromine based swimming pool chemicals
•
De-icing salts or chemicals (rock salt, etc.)
• Dry
cleaning
fl
uids such as perchloroethylene
•
Fumes from curing polyurethane and similar substances
•
Halogen based refrigerants including R-12 and R-22
•
Hydrochloric acid, muriatic acid and other acid based masonry washing and curing materials
•
Printer’s inks, paint removers, varnishes, varsol, toluene, etc.
•
Water softener salt and chemicals
2. If this furnace is to be installed in an area over a
fi
nished ceiling or living area, install a
fi
eld fabricated
auxiliary drain pan under the furnace to protect that area from accidental condensate spills. The auxiliary
pan should be large enough to collect accidentally spilled condensate from the air conditioning evaporator
coil assembly if applicable.
3. If the furnace is installed in an area where freezing may occur, a garage, an attic, a crawl space or any
unconditioned space, steps must be taken to protect the condensate trap and drain line from freezing.
