Vent Pipe Runs

All Power Vented water heaters generate a certain amount of operational noise. In order to minimize noise transmission to floor joists though hangers, place some soft material such as foam rubber, approximately 12mm (1/2 in.) thick, between hangers and the vent pipes.

1.	Horizontal runs must not, under any circumstances, run
	downhill then run uphill thus forming a valley where con-
	densation can accumulate and block the vent pipe.
2.	Horizontal runs require a minimum 3mm (1/8 in.) rise
	per 1.5m (5 ft) and a support every 1.2m (4 ft.). Ensure
	there is enough height between heater and termination
	to raise vent pipe runs the required distance.
3.	Vertical runs require a support every 1.5m (5 ft.) that
	must provide proper support to prevent stress on the

Vent Pipe Connection to Blower

A rubber coupling is supplied with the water heater to con- nect the venting to the blower using gear clamps (supplied). Important: These connections must be properly sealed to prevent the leakage of the products of combustion into the living area.

ABS and CPVC vent piping may be directly connected to the blower assembly as shown in Figures 15 & 16. For heaters installed as shown in Figure 15 (c), order 50mm (3 in.) rub- ber coupling connector (P/N 63234).

PVC vent pipe installations must use a PCV vent conversion kit as shown in Figure 14. Order PVC Vent Conversion Kit P/N 73901 for 50mm (2 in.) vent pipe installations. For 76mm (3 in.) vent pipe installations order PVC Vent Conversion Kit P/N 73876.

1.	Clean and lightly sand the end of the vent pipe that will
	connect to the rubber coupling. This will ensure a good
	mechanical connection between the coupling and the
	pipe.
2.	Apply solvent cement and join the PVC coupling of the
	adaptor to the venting system. (PVC Only).
3.	At the rubber coupling, loosen the upper gear clamp to
	allow the vent piping to be inserted fully 32mm (1-1/4
