Venting System Condensation
Condensate formation does not occur in all installations of power vented water
heaters, but should be protected against on installations where condensation
can form in the venting system.
Formation of condensation in the venting system of Power Vented water
heaters is dependent upon installation conditions including, but not limited to:
ambient temperature and humidity of installation location;
ambient temperature and humidity of venting space;
vent distance and slope;
and product usage.
In order to effectively control condensate from adversely affecting the
mechanical components of the water heater several methods may be
employed:
1. For horizontal installations the vent pipe can be installed with a
downward slope (not less than 1/8" (3 cm)) and away from the blower.
2. In order to prevent condensate from draining back into the blower
(vertical or horizontal runs), an optional condensate kit is available as a
service part (Condensate kit, p/n 239-45875-00). A factory supplied
exhaust adapter with drain outlet mounts directly to the blower outlet
and is secured with two hose clamps, one to the blower and the other
to the vent pipe. Tubing is provided to drain any accumulated
condensate away from the water heater and to a suitable drain. The kit
comes complete with instructions for proper installation.
Part I - Venting Specifications for:
48 Gallon (181.6 L)
65 Gallon (246.0 L)
This water heater is a power vented appliance and is designed to vent its
products of combustion through 3" (7.6 cm) or 4" (10.2 cm) diameter vent pipe
to the outdoors. This water heater may be either vented horizontally through
the wall or vertically through the roof. Use a 3" (7.6 cm) to 4" (10.2 cm) reducer
to connect to the vent outlet when using 4" (10.2 cm) vent pipe. Apply the
proper cement at the joint locations. Table 1 lists the maximum vent lengths for
this water heater using 3" (7.6 cm) vent pipe. If possible, locate the water
heater so that the venting length and number of elbows are kept to the
minimum distance necessary to reach the outside. If the installation requires
venting lengths that exceed the lengths listed for 3" (7.6 cm) vent pipe in Table
1, then use 4" (10.2 cm) vent pipe for the vent connector.
