INSTALLATION CONSIDERATIONS
Alternate Electrical and Gas Line Connections
The furnaces have provisions allowing for electrical and gas
line connections through either side panel. In horizontal ap-
plications the connections can be made either through the
"top" or "bottom" of the furnace.
Drain Pan
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).
Freeze Protection
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. NOTE: The use
of insulation and/or heat tape is recommended. Failure to
provide proper condensate drainage can result in property
damage.
Propane Gas and/or High Altitude Installations
P
OSSIBLE PROPERTY DAMAGE, PERSONAL INJURY OR DEATH MAY OCCUR IF
THE CORRECT CONVERSION KITS ARE NOT INSTALLED.
MUST BE APPLIED TO INSURE SAFE AND PROPER FURNACE OPERATION.
CONVERSIONS MUST BE PERFORMED BY A QUALIFIED INSTALLER OR SERVICE
AGENCY.
This furnace is shipped from the factory configured for natu-
ral gas at standard altitude. Propane gas installations re-
quire an orifice change to compensate for the energy con-
tent difference between natural and propane gas.
High altitude installations may require both a pressure switch
and an orifice change. These changes are necessary to com-
pensate for the natural reduction in the density of both the
gas fuel and the combustion air at higher altitude.
Refer to the Accessories Charts in this manual or product
Specification Sheet for a tabular listing of appropriate
manufacturer's kits for propane gas and/or high altitude in-
stallations. The indicated kits must be used to insure safe
and proper furnace operation. All conversions must be per-
formed by a qualified installer, or service agency.

PERSONAL INJURY OR DEATH DUE TO EXPOSURE TO FLUE PRODUCTS,
INCLUDING CARBON MONOXIDE.
A condensing gas furnace achieves its high level of efficiency
by extracting almost all of the heat from the products of
combustion and cooling them to the point where condensa-
tion takes place. Because of the relatively low flue gas tem-
perature and water condensation requirements, PVC pipe is
used as venting material.
This furnace must not be connected to Type B, BW, or L
vent or vent connector, and must not be vented into any
portion of a factory built or masonry chimney except when
used as a pathway for PVC as described later in this sec-
tion. Never common vent this appliance with another appli-
ance or use a vent which is used by a solid fuel appliance.
It is the responsibility of the installer to follow the manufac-
turers' recommendations and to verify that all vent/flue pip-
ing and connectors are compatible with furnace flue prod-
ucts. Additionally, it is the responsibility of the installer to
ensure that all piping and connections possess adequate
LL structural integrity and support to prevent flue pipe separa-
tion, shifting, or sagging during furnace operation.
Materials and Joining Methods
T
O AVOID BODILY INJURY, FIRE OR EXPLOSION, SOLVENT CEMENTS MUST BE
KEPT AWAY FROM ALL IGNITION SOURCES (I.E., SPARKS, OPEN FLAMES, AND
EXCESSIVE HEAT) AS THEY ARE COMBUSTIBLE LIQUIDS.
CEMENT VAPORS OR CONTACT WITH SKIN AND/OR EYES.
Precautions should be taken to prevent condensate from
freezing inside the vent/flue pipe and/or at the vent/flue pipe
termination. It is our recommendation that all vent/flue piping
exposed to temperatures below 35°F for extended periods
of time should be insulated with 1/2" thick closed cell foam.
Also all vent/flue piping exposed outdoors in excess of the
terminations shown in this manual (or in unheated areas)
should be insulated with 1/2" thick closed cell foam. Inspect
piping for leaks prior to installing insulation.
The following bullets and diagram describe the restrictions
concerning the appropriate location of vent/flue pipe and com-
bustion air intake pipe (when applicable) terminations. Re-
fer to the installation instructions for specific details on ter-
mination construction.
• All terminations must be located at least 12 inches
above ground level or the anticipated snow level.
• Vent terminations must terminate at least 3 feet above
any forced air inlet located within 10 feet.
