Alternate Electrical And Gas Line Connections; Drain Pan; Freeze Protection; Furnace Suspension - Amana GUCA Installation Instructions Manual

ALTERNATE ELECTRICAL AND GAS LINE
CONNECTIONS
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 "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

Refer to Section VI, Horizontal Applications and Conditions
- Drain Trap and Lines.

FURNACE SUSPENSION

If the furnace is installed in a crawl space it must be
suspended from the floor joist or supported by a concrete
pad. Never install the furnace on the ground or allow it to
be exposed to water. Refer to Section IV, Location Require-
ments and Considerations - Furnace Suspension for fur-
ther details.
VIII. Propane Gas and/or

High Altitude Installations

WARNING
Possible death, personal injury or property
damage may occur if the correct conversion
kits are not installed. The appropriate kits
must be applied to insure safe and proper
furnace operation. All conversions must
be performed by a qualified installer or
service agency.
This furnace is shipped from the factory configured for
natural gas at standard altitude. Propane gas installations
require an orifice 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 change. These changes are neces-
sary to compensate for the natural reduction in the density
of both the gas fuel and the combustion air at higher
altitude.
Refer to the product Specification Sheet or contact an
distributor for a tabular listing of appropriate manufacturer's
kits for propane gas and/or high altitude installations. 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.
IX. Vent/Flue Pipe
& Combustion Air Pipe

GENERAL

WARNING
Failure to follow these instructions can
result in bodily injury or death. Carefully
read and follow all instructions given in
this section.
WARNING
Upon completion of the furnace installation,
carefully inspect the entire flue system
both inside and outside the furnace to
assure it is properly sealed. Leaks in the
flue system can result in serious personal
injury or death due to exposure to flue
products, including carbon monoxide.
A condensing gas furnace achieves its high level of effi-
ciency by extracting almost all of the heat from the products
of combustion and cooling them to the point where conden-
sation takes place. Because of the relatively low flue gas
temperature 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
section. Never common vent this appliance with another
appliance or use a vent which is used by a solid fuel
appliance. Do not use commercially available "no hub
connectors" other than those shipped with this product.
It is the responsibility of the installer to follow the manufac-
turers' recommendations and to verify that all vent/flue
piping and connectors are compatible with furnace flue
products. Additionally, it is the responsibility of the installer
to ensure that all piping and connections possess adequate
structural integrity and support to prevent flue pipe separa-
tion, shifting, or sagging during furnace operation.

DUAL CERTIFICATION: NON-DIRECT/DIRECT VENT

This furnace is dual certified and may be installed as a non-
direct vent (single pipe) or direct vent (dual pipe) appliance.
A non-direct vent installation requires only a vent/flue pipe,
while a direct vent installation requires both a vent/flue pipe
and a combustion air intake pipe. Refer to the appropriate
section for details concerning piping size, length, number of
elbows, furnace connections, and terminations.
