same procedures as used for system piping.

DO NOT CE-

MENT POLYPROPYLENE FITTINGS.

(Direct Vent / 2-Pipe System ONLY)

When two or more furnaces are vented near each other, two vent

terminations may be installed as shown in Fig. 52, but next vent
termination, or pair of vent terminations, must be at least 36 in.

(914 mm) away from the first two terminations. It is important that

vent terminations be made as shown in Fig. 52 to avoid
recirculation of vent gases.

Inducer Outlet Restrictor

To improve efficiency and operation of 40,000 BTUH input
models on very short vent systems, an inducer outlet restrictor is

required to be installed on the outlet of the inducer assembly. The
outlet restrictor is shipped in the loose parts bag.
To determine if the outlet restrictor is required, see Table 16.

Failure to use an outlet choke when required may result in

flame disturbance or flame sense lockout.

To install the outlet restrictor:

1. Remove the vent elbow from the inducer outlet.
2. Align the lock tabs on the outlet restrictor with the slots on

inside outlet of the inducer assembly.

3. Snap the outlet restrictor in place.
4. Re-install the vent elbow.
5. Torque vent elbow clamp 15-lb--in.
