Horizontal Venting Through The Wall; Downward Venting - Trane UHMB060ACV3VA Installer's Manual

HORIZONTAL VENTING THROUGH WALL
IMPORTANT:
The building owner/maintenance provider must
keep the area around the vent clear from snow.
These furnaces may be installed as direct vent (as
shipped) or as non-direct vent. Installation must
conform to national, state, and local codes.
The vent & inlet terminals must be located at least 12"
minimum above normally expected snow accumulation
level. See Figure 29.
Avoid areas where staining or condensate drippage may
be a problem.
Location of the vent/ wind terminal should be chosen to
meet the requirements of Figure 30 and Tables 11 and
12 for either direct or non-direct vent applications.
PITCH – Venting through the wall must maintain 1/4"
per foot pitched upward to insure that condensate
drains back to the Furnace.

DOWNWARD VENTING

j
Furnace may be in vertical or horizontal configuration.
All horizontal pipes must be
supported at a maximum of
3 foot intervals
NOTES:
Condensate trap for Vent Pipe must be a minimum of 6 inches in height.
A)
Condensate trap for Vent and Inlet Pipe must be connected into a condensate drain pump; an open or
B)
vented drain; or it can be connected to the outlet hose of the Furnace's condensate trap. Outdoor draining
of the Furnace and coil condensate is permissible if allowed by local codes. Caution should be taken to
prevent drains from freezing or causing slippery conditions that could lead to personal injury. Excessive
draining of condensate may cause saturated ground conditions that may result in damage to plants.
The condensate trap should be primed at initial start up prior to heating season operation.

FLUE GAS DEGRADATION – The moisture content of
the flue gas may have a detrimental effect on some
building materials. This can be avoided by using the
roof or chimney venting option. When wall venting is
used on any surface that can be affected by this mois-
ture, it is recommended that a corrosion resistant
shield (24 inches square) be used behind the Vent Ter-
minal. This shield can be wood, plastic, sheet metal,
etc. Also, silicone caulk all cracks, seams and joints
within 3 feet of the Vent Terminal.
The vent for this appliance shall not terminate
