Roof terminations--

Locate assembly through roof to

appropriate height as shown in Fig. 31 and 32.

Sidewall

terminations--

Locate

assembly

through

sidewall with rain shield positioned no more than 1--in.

from wall as shown in Fig. 31 and 32.

4. Disassemble loose pipe fittings. Clean and cement using

same procedures as used for system piping.

5. Check required dimensions as shown.

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

properly cut vent pipe. Coupling must be positioned so

bracket will mount as shown in Fig. 31.
For applications using combustion--air pipe option,

indicated by dashed lines in Fig. 31, 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.

31.

For applications using vent pipe option indicated by
dashed lines in Fig. 31, rotate vent elbow 90

from

position shown in Fig. 31.

3. Disassemble loose pipe fittings. Clean and cement using

same procedures as used for system piping.

4. Check required dimensions as shown in Fig. 31.

Multiventing and Vent Terminations

When 2 or more 58UVB Furnaces are vented near each other,

each furnace must be individually vented. NEVER common vent
or breach vent 58UVB furnaces.

(Direct Vent/2--Pipe System ONLY)--When 2 or more 58UVB
furnaces are vented near each other, 2 vent terminations may be

installed as shown in Fig. 31, 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. 31 to avoid

recirculation of flue gases.
