penetration of wall or roof is desired.
4. The 3=in. concentric vent/air tet_nination kit is for 2-1/2 in.,
3=in., and 4=in. diameter pipe systems when single penetration
of wall or roof is desired.
NOTE: Shaded parts in Fig. 35, 37, 38, 39, and 40 are considered
to be tet_ninafion These components should NOT be counted
when detem_ining pipe diameter Roof termination is preferred
since it is tess susceptible to damage, has reduced chances to take
in contaminants, and has less visible vent vapors (See Fig 36 or
37.) Sidewall termination may require sealing or shielding of
building surfaces with a corrosive resistance material due to
corrosive combustion products of vent system.
Extended Exposed Sidewall Pipes
Sidewall combustion-air and vent pipe terminations may be
extended beyond area shown in Fig. 39 or 40 in outside ambient by
insulating pipes as indicated in Table 8.
1. Determine combustion-air and vent pipe diameters, as stated
above, using total pipe length and number of elbows.
2. Using winter design temperature (used in toad calculations),
find appropriate temperature _br your application and [:urnace
model.
3. Determine required insulation thickness _br exposed pipe
lengths
NOTE: Pipe length (ft) specified fbr maximum pipe lengths
located in unconditioned spaces cannot exceed total allowable pipe
length as specified in Table 7.
Two=Pipe Termination Kit
1. Determine location for tem_ination.
(onsideration of the fbllowing should be made when deter-
mining an appropriate location for tem_ination kit.
a. (omply with all clearance requirements as stated in Table
5.
b. Termination kit should be positioned where vent vapors
will not damage plants/shrubs or air conditioning equip°
ment.
c. Termination kit should be positioned so that it will not be
affected by wind ed@ (such as inside building corners) or
allow recirculafion of flue gases, airborne leaves, or light
snow.
d. Terminafion kit should be positioned where it will not be
damaged by or subjected to _breign objects, such as stones,
balls, etc.
e. Tem_inafion kit should be positioned where vent vapors are
not objectionable.
2. Cut 2 holes, 1 for each pipe, of appropriate size _br pipe size
being used.
3. Loosely install elbow in bracket and place assembly on
combustion=air pipe.
Roof terminations Loosely install pipe coupling on prop°
erly cut vent pipe. Coupling must be positioned so bracket will
mount as shown in Fig. 36.
For applications using combustion=air pipe option, indicated
by dashed lines in Fig. 36, install 90 _>street elbow into 90 _>
elbow, making U-fitting. A 180 _>U=fitting may be used.
Sidewall terminations Install bracket as shown in Fig. 39 or
40.
For applications using vent pipe option indicated by dashed
lines in Fig 39, rotate vent elbow 90 _>from position shown in
Fig. 39
4. Disassemble loose pipe fittings. Clean and cement using same
procedures as used _br system piping.
5. Check required dimensions as shown in Fig. 36, 39, or 40.
Concentlic Vent/Air Temaination Kit
1. Determine location %r tem_ination.
Consideration of the _bllowing should be nrade when deter-
mining an appropriate location [br tem_ination kit.
a (ompty with all clearance requirements as stated in Table
5
b. Termination kit should be positioned where vent vapors
will not damage plants/shrubs or air conditioning equip°
nlent.
c Termination kit should be positioned so it will not be
affected by wind ed@ (such as inside building corners) or
that may allow recirculation of flue gases, airborne leaves,
or light snow
d. Temainafion kit should be positioned where it will not be
damaged by or subjected to foreign ohjects, such as stones,
balls, etc.
e Tem_ination kit should be positioned where vent vapors are
not objectionable.
2. Cut one 4=in. diameter hole _:br 2=in. kit, or one 5-in. diameter
hole £_r 3°in. kit.
3. Loosely assemble concentric vent/air terminafion con_ponents
together using instructions in kit
4. Slide assembled kit with rain shield REMOVED through hole.
NOTE: Do not allow insulation or other materials to accumulate
inside of pipe assembly when installing it through hole.
Roof terminations Locate assembly through roof to appro-
priate height as shown in Fig. 37.
Sidewall terminations Locate assembly through sidewall
with rain shield positioned no more than l-in. from wall as
shown in Fig. 38.
5. Disassemble loose pipe fittings. Clean and cement using same
procedures as used t:br system piping.
6. Check required dimensions as shown in Fig. 37 or 38.
ML LTIVENTING AND VENT TERMINATIONS
When 2 or more 58MCA Furnaces are vented near each other, each
furnace must be individually vented. NEVER common vent or
breach vent 58MCA _hrnaces. When 2 or more 58MCA l\a'naces
are vented near each other, 2 vent tem_inations may be installed as
shown in Fig. 41, 42, 43, 44, or 45, but next vent tem_ination must
be at least 36 in. away from first 2 terminations. It is important that
vent tem_inations be made as shown to avoid recirculation of flue
gases. Dimension "A" in Fig. 41, 42, 43, 44, and 45 represents
distance between pipes or rain shields, as touching or 2=in.
maximum separation.
