Condensation
and Power Vented Water Heaters
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
- Product usage
- Condensate formation does not occur in all installations
of power vented heaters, but must be protected against
installations where condensation can form in the venting
system.
Bradford White Installation and Operation Instructions
state the need to protect against the effects of condensation.
Bradford White also supplies a condensate fitting with
the water heater package for ease in effecting condensate
control.
While the method described in our Instructions is an
effective method to control condensate, it is not the
only method. Other methods of condensate management may
be employed to achieve this goal, such as slight sloping
(not less than 1/8" nor greater than 1/2" per foot maximum)
of the vent down (and away from the blower motor) if necessary
for the particular installation.
Power Vented Product Installations that employ effective
condensate management techniques shall be deemed in compliance
with Bradford White Limited Warranties and Installation/Operation
Instructions.
Failure of the water heater and/or components related
to ineffective condensation control is not covered by
any warranty.
