INSTALLATION
A. Horizontal Termination
Refer to Chart A for horizontal venting recommendations. The
minimum vertical rise allowed for horizontal termination is 2' from
the top of the heater. The maximum horizontal run allowed for
venting is 15' with a minimum 4' rise.
CHART A
Note: A horizontal run of vent must have
a 1/4" rise for every 1 ft. of run towards
the termination. Never allow the vent to
run downward. This could cause high
temperatures and the possibility of a fire.
Fig. 3 - Horizontal Lenth
A single vertical to horizontal elbow is already calculated into the
allowable 15' run. Each additional elbow reduces the maximum
horizontal distance by three feet. Example: When using three
elbows, the maximum horizontal distance has been reduced to
9' (3 - 1 = 2 elbows x 3' = 6'; 15' max. - 6' of elbows = 9' of
horizontal run). Even with only these three elbows (the equivalent
of 6' additional horizontal feet) you now need a minimum of 4' of
vertical rise. See Chart A.
If a vertical-to-horizontal elbow is enclosed within a wall, floor or
ceiling, an air space clearance of 3" must be maintained.
Due to the many different combineations that can be used when
constructing venting, the number of vent sections required can
only be determined by the installer.
Horizontal venting must terminate within the shaded area shown in
Fig. 2. Chart A illustrates the figures included in that shaded area.
For example, if your vertical rise is the minimum two foot, venting
can terminate anywhere between 20 -1/2" (includes wall thickness
and assumes 4", and venting required to termination cap) and 10'.
Vent termination must not be recessed into the wall or siding.
Fig. 3 illustrates termination cap location and minimum dimensions
for each termination application. Or, follow ANSI Z223.1, latest
edition.
01-01 Page 9 29863C
Note: Horizontal runs will require the use of
one vent support for every 3' of vent.
