HORIZONTAL INSTALLATION
(UPFLOW/ HORIZONTAL OR DOWNFLOW/ HORIZONTAL)
NOTE:
See Figures 23 & 24. In horizontal venting when the
factory supplied "off-set" (2X3 reducing coupling)
is used for 3" vent pipe installation, make sure the
marking "Top" is located on the top side of the pipe.
The straight side must be on bottom for proper
condensate drainage. This coupling is factory supplied
with the following models: *UHMC100, *UHMD120, & all
downflow models.
WARNING
L !
Carbon monoxide, fire or smoke can cause serious bodily
injury, death, and/ or property damage.
A variety of potential sources of carbon monoxide can
be found in a building or dwelling such as gas-fired
clothes dryers, gas cooking stoves, water heaters,
Furnaces and fireplaces. The U.S. Consumer Product
Safety Commission recommends that users of gas-
burning appliances install carbon monoxide detectors as
well as fire and smoke detectors per the manufacturer's
installation instructions to help alert dwelling occupants
of the presence of fire, smoke or unsafe levels of carbon
monoxide. These devices should meet Underwriters
Laboratories, Inc. Standards for Single and Multiple
Station Carbon Monoxide Alarms, UL 2034 or CSA
International Standard, Residential Carbon Monoxide
Alarming Devices, CSA 6.19
NOTE: The manufacturer of your furnace does not test
any detectors and makes no representations regarding
any brand or type of detector.
IMPORTANT: These furnaces may be installed as Direct
Vent (sealed combustion) or as Nondirect Vent (single
pipe). The furnaces are shipped DIRECT VENT with sealed
combustion.
For DIRECT VENT APPLICATION: The furnaces must
be vented to the exterior of the house and combustion air
MUST come through the inlet air pipe FROM OUTSIDE
AIR. The pipes DO NOT have to exit the exterior of the
house together or on the same side of the house.

combustion air requirements are met. (See AIR FOR

WARNING
L !
CARBON MONOXIDE POISONING HAZARD
Failure to follow the installation instructions for the
venting system being placed into operation could
result in carbon monoxide poisoning or death.
There are many different variations of the vent/ inlet air
pipe combination. The vent/ inlet air combination used for
installation of these furnaces depends on the needs of
the location. However, these guidelines must be followed:
1. The Furnace must vent outside the structure.
2. Furnace combustion air requirements must be met
for nondirect, single pipe applications (See ex. 2 ).
3. For direct vent application of these furnaces, the vent
pipe and air inlet pipe do not have to exit in the same air
space or even on the same surface of the structure.
However, the longest individual pipe will decide the value
for the longest allowable equivalent vent/ inlet air length
as shown in the vent length table.
NOTE:
BAYVENT200B accessories can be used for inlet
and outlet terminals when the pipes do not exit
the structure together. For Canadian applications
ONLY, IPEX 196006 may be used for horizontal and
vertical terminations. IPEX 081216, IPEX 081218, and
IPEX 081219 may be only used for horizontal vent
terminations.
The following are EXAMPLES ONLY:
EX. 1 —
Example 1 shows that the vent may go vertical while the
inlet air may be on any side of the structure. The Vent
Pipe would decide the maximum equivalent length for the
pipe depending on the furnace and pipe size.
