DIRECT VENT (2-PIPE) TERMINATION KIT
2-in. Concentric Vent Kit
3-in. Concentric Vent Kit
2-in. Termination Bracket Kit
3-in. Termination Bracket Kit
4. Termination or termination kit should be positioned where it
will not be damaged by or subjected to foreign objects such as
stones, balls, etc.
5. Termination or termination kit should be positioned where
vent vapors are not objectionable.
Extended Exposed Sidewall Pipes
Sidewall combustion air pipe termination (direct vent/2-pipe
system only) and vent pipe termination may be extended beyond
area shown in Fig. 42 or in Fig. 43 per application in outside
ambient by insulating pipe as indicated in Table 10.
1. Determine combustion air pipe diameter (direct vent/2-pipe
system only) and vent pipe diameter, as stated above, using
total pipe length and number of elbows.
2. Using winter design temperature (used in load calculations),
find appropriate temperature for your application and furnace
model.
3. Determine required insulation thickness for exposed pipe
length(s).
NOTE: Pipe length(ft) specified for maximum pipe lengths lo-
cated in unconditioned spaces cannot exceed total allowable pipe
length as specified in Table 11.
Vent Termination Kit (Direct Vent/2-Pipe System Only)
NOTE: Always refer to the instructions in termination kit for the
latest version.
Combustion air and vent pipes MUST terminate outside structure.
A factory accessory termination kit must be installed as shown in
Table 12. There are four options of vent/combustion air termina-
tion kits available as shown in Table 12.
NOTE: Combustion air pipe must have the same diameter as vent
pipe.
Concentric Vent/Combustion Air Termination Kit (Direct Vent/
2-Pipe System Only)
Determine an appropriate location for termination kit using the
guidelines provided in section "Vent Termination: General" in this
instruction.
1. Cut one 4-in. diameter hole for 2-in. kit, or one 5-in. diameter
hole for 3-in. kit.
2. Loosely assemble concentric vent/combustion air termination
components together using instructions in kit.
3. 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. 42.
Sidewall terminations—Locate assembly through sidewall
with rain shield positioned no more than 1-in. from wall as
shown in Fig. 42.
4. Disassemble loose pipe fittings. Clean and cement using same
procedures as used for system piping.
5. Check required dimensions as shown in Fig. 42.

Two-Pipe Termination Kit (Direct Vent/2-Pipe System Only
Determine an appropriate location for termination kit using the
guidelines provided in section "Vent Termination: General" in this
instruction.
1. Cut 2 holes, 1 for each pipe, of appropriate size for pipe size
being used.
2. 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. 42.
For applications using combustion-air pipe option, indicated
by dashed lines in Fig. 42, install 90° street elbow into 90°
elbow, making a U-fitting. A 180° U-fitting may be used.
Sidewall terminations—Install bracket as shown in Fig. 42.
For applications using vent pipe option indicated by dashed
lines in Fig. 42, rotate vent elbow 90° from position shown in
Fig. 42.
3. Disassemble loose pipe fittings. Clean and cement using same
procedures as used for system piping.
4. Check required dimensions as shown in Fig. 42.
Multiventing and Vent Terminations
When 2 or more 58MXB Furnaces are vented near each other, each
furnace must be individually vented. NEVER common vent or
breach vent 58MCB furnaces.
(Direct Vent/2-Pipe System ONLY)-When 2 or more 58MCB
furnaces are vented near each other, 2 vent terminations may be
installed as shown in Fig. 42, but next vent termination must be at
least 36 in. away from first 2 terminations. It is important that vent
terminations be made as shown in Fig. 42 to avoid recirculation of
flue gases.
Step 11—Condensate Drain

GENERAL

Condensate trap is shipped installed in the blower shelf and factory
connected for UPFLOW applications. Condensate trap must be
RELOCATED for use in DOWNFLOW and HORIZONTAL
applications.
Condensate trap MUST be used for all applications.
An external trap is not required when connecting the field drain to
this condensate trap.
The field drain connection (condensate trap or drain tube coupling)
is sized for l/2-in. CPVC, 1/2-in. PVC, or 5/8-in. ID tube
connection.
Drain pipe and fittings must conform to ANSI standards and
ASTM D1785, D2466 or D2846. CPVC or PVC cement must
conform to ASTM D2564 or F493. Primer must conform to ASTM
F656. In Canada, use CSA or ULC listed schedule 40 CPVC or
PVC drain pipe, fittings, and cement.
When a condensate pump is required, select a pump which is
approved for condensing furnace applications. To avoid conden-
sate spillage, select a pump with an overflow switch.
