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 mark-
ing "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 fol-
lowing models: *UHMC100, *UHMD120, & all downflow
models.

WARNING
!
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 Commis-
sion recommends that users of gas-burning appliances
install carbon monoxide detectors as well as fire and
smoke detectors per the manufacturer's installation in-
structions to help alert dwelling occupants of the pres-
ence 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 De-
vices, CSA 6.19
NOTE:
The manufacturer of your furnace does not test any de-
tectors 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 fur-
naces 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.

WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow the installation instructions for the
venting system being placed into operation could re-
sult 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 example
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 struc-
ture together. For Canadian applications ONLY, IPEX
196006 may be used for horizontal and vertical termi-
nations. 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.
