DO NOT install the vent pipe in the same chase with the vent from another fuel burning appliance,
except with a GMN, GMPN, GSUS, or GSU furnace
manufactured
by GOODMAN.
DO NOT install the vent pipe within six (6) inches of another fuel burning appliance.
The drain trap must be easily accessible
for checking
and / or cleaning.
It must be mounted
as
shown elsewhere
in this I&O.
DO NOT install the trap higher than the venter blower outlet.
DO NOT install this appliance
in any area where freezing may occur without properly protecting
the drain assembly.
DO NOT terminate
the vent under a deck or overhang
or where a positive pressure
or the
recirculation
of vent products
may occur.
CONSULT
LOCAL CODES FOR SPECIAL
ADDITIONAL
REQUIREMENTS.
THE COMBUSTION
PRODUCTS
AND MOISTURE
IN THE FLUE GASES WILL CONDENSE.
THE CONDENSATE
MAY FREEZE
ON THE EXTERIOR
WALL AND SURROUNDING
SURFACES.
SOME DISCOLORATION
OR ETCHING
IS TO BE EXPECTED.
When selecting
which exterior wall to penetrate
the following
items should be taken into
consideration:
Layout the vent system to avoid the possibility
of interference
with beams, poles, posts, electrical
wiring, plumbing,
etc.
When possible the vent termination
should not be subjected
to prevailing
winds.
The vent termination
must be located at least twelve (12) inches above grade or expected
snow
depth. Consideration
should
be given to past unusual snow falls.
•
DO NOT locate the terminal
less than seven (7) feet above public walkways
or where it could
cause a nuisance
or hazard.
This also applies to steps and stairwells.
•
DO NOT locate the termination
where condensate
may present a problem
such as flower
beds, patios, etc.
•
DO NOT locate within four (4) feet of a gas or electric meter or gas regulator.
•
DO NOT locate the vent terminal within four (4) feet between
buildings.
•
DO NOT locate the vent terminal less than twelve (12) inches above a door or an operable
window.
•
DO NOT locate the vent terminal less than four (4) feet below OR four (4) feet horizontally
from, any door, window,
or gravity air inlet into any building.
•
DO NOT locate the vent terminal within three (3) feet of an inside corner of a building or
structure.
A minor inside corner formed
by a masonry
chimney
is an exception
to this
requirement.
To protect the exterior surface from staining
due to the condensate
an aluminum
plate or similar
material may be installed
surrounding
the termination.
This plate should extend approximately
two
(2) feet from the penetration.
CAUTION
The area surrounding
the vent pipe must be kept free of snow, trash, bushes or any other
obstacle
which may cause a blockage.
A blockage
can cause CARBON
MONOXIDE
to enter the
building.
SUPPORTING
AND PITCHING
THE VENT
All horizontal
runs must be supported
at least every five (5) feet and at joints with straps or
hangers.
No sags or dips are permitted.
The pipe must be saddle supported
only. Do not secure
the hangers
or straps tightly to the pipes, allow for expansion
and contraction
of the vent pipe
material.
Maintain a 1/4 " per foot minimum
pitch upward on the horizontal
vent
pipe from the
IO-151
