5.Install rain cap and small diameter pipe assembly in Y concentric fitting and large pipe assembly. Ensure small diameter pipe is bottomed and cemented in Y concentric fitting.

6.Secure assembly to structure as shown in Figure 24 using field- supplied metal strapping or equivalent support material.

NOTE: Ensure termination location clearance dimensions are as shown in the diagrams found in Figure 24 and 25. When extending the length of the 4” pipe, the added length beyond 21-1/8” must be deducted from the maximum equivalent feet of vent pipe.

NOTE: If assembly needs to be extended to allow side wall thickness requirement, the 2 pipes supplied in the kit may be replaced by using same diameter, field-supplied SDR-26 PVC (D2241) pipe. Do not extend 21 1/8” dimension more than 60 in. (See Figure 20.)

Do not use field-supplied couplings to extend pipes. Airflow restriction will occur and the heater pressure switch may cause intermittent operation.

7.Cement heater combustion-air and vent pipes to concentric vent termination assembly. See Figure 25 for proper pipe attachment.

8.Operate heater through 1 heat cycle to ensure combustion-air and vent pipes are properly connected to concentric vent termination connections.

MULTI-CONCENTRIC VENT TERMINATIONS

When two or more appliances are direct vented with concentric vent terminations near each other, each appliance must be individually vented. NEVER common vent this appliance. When two or more appliances are direct vented using concentric vent terminations, the appliances may be vented as shown in Figure 26 and 27.
