Drain Trap And Lines; Horizontal Furnace Leveling; Lternate Lectrical And As Ine; Propane Gas/High Altitude Installations - Goodman MEC961205DN Instruction Manual

RAIN RAP AND INES
In horizontal applications the condensate drain trap is secured to
the furnace side panel, suspending it below the furnace. A mini-
mum clearance of 5.5" below the furnace must be provided for
the drain trap. Additionally, the appropriate downward piping
slope must be maintained from the drain trap to the drain loca-
tion. Refer to Condensate Drain Trap and Lines for further de-
tails. If the drain trap and drain line will be exposed to tempera-
tures near or below freezing, adequate measures must be taken
to prevent condensate from freezing.

ORIZONTAL URNACE
Leveling ensures proper condensate drainage from the heat ex-
changer. For proper flue pipe drainage, the furnace must be
level lengthwise from end to end. The furnace should have a
slight tilt from back to front with the access doors downhill
from the back panel approximately 1/2 to 3/4 inches. The
slight tilt allows the heat exchanger condensate, generated in
the recuperator coil, to flow forward to the recuperator coil front
cover.

LTERNATE LECTRICAL AND
This furnace has provisions allowing for electrical and gas line
connections through either side panel. In horizontal applications
the connections can be made either through the "top" or "bot-
tom" of the furnace.

RAIN AN
A drain pan must be provided if the furnace is installed above a
conditioned area. The drain pan must cover the entire area
under the furnace (and air conditioning coil if applicable).

This furnace is shipped from the factory configured for natural
gas at standard altitude. Propane gas installations require an
orifice and spring change to compensate for the energy content
difference between natural and propane gas.
High altitude installations may require both a pressure switch
and an orifice/spring change. These changes are necessary to
compensate for the natural reduction in the density of both the
gas fuel and the combustion air at higher altitude. For furnaces
being converted to LP gas, it is strongly recommended that
a LPLP03 kit also be installed. The use of this kit will prevent
the furnace from firing when the LP gas supply pressure is
too low to support proper combustion.

For installations above 7000 feet, please refer to the furnace
Specification Sheets for required kit(s).
Contact the distributor for a tabular listing of appropriate
manufacturer's kits for propane gas and/or high altitude instal-
lations. The indicated kits must be used to insure safe and
proper furnace operation. All conversions must be performed by
a qualified installer, or service agency.

This manual will refer to the pipe that discharges products
of combustion to the outdoors as the "vent" pipe or "flue"
pipe. The pipe that supplies air for combustion to the fur-
nace will be referred to as the "intake" pipe or "combustion
air" pipe.
A condensing gas furnace achieves its high level of efficiency by
extracting almost all of the heat from the products of combus-
tion and cooling them to the point where condensation takes
place. Because of the relatively low flue gas temperature and

water condensation requirements, PVC or ABS are typically used
as venting and intake pipe materials. In Canada, ABS is not
an approved vent pipe material but it is permissible to use
as combustion air pipe material.
In addition to PVC and ABS pipe and fittings, Innoflue
Centrotherm Eco Systems and PolyPro
also approved vent and combustion air materials for instal-
lations in the U.S.A. and Canada. Manufacturers Installation
instructions for these products must be followed. These prod-
ucts have specific instructions for installing, joining and ter-
minating. Do not mix materials or components of one manu-
facturer with materials or components of another manufac-
turer.
All furnaces are manufactured with 2" vent / intake pipe and
connectors. For furnaces requiring installation of 3" pipe,
