Installation Manual
Humidity and contact with water
Avoid places with excessive humidity. The boiler has electric gas
ignition components. If water gets inside the boiler, the ignition
system can be damaged. The boiler must be installed in such a way
as to ensure that the gas ignition system components are protected
from water (dripping, spraying, rain, etc.) during operation and
service.
Drainage
A signifcant amount of condensate is produced during the boiler
operation. Install the boiler near a suitable drain and where
damage from a possible leak will be minimal. Installing the boiler
without a drain will void the warranty. For more information about
condensate drainage, refer to "Connection the Condensate Drain" on
page 20.
The Boiler must be located in an area where leakage of the unit or
connections will not result in damage to the area adjacent to the
appliance or to lower foors of the structure. When such locations
cannot be found, installation of an adequately-draining drain pan
under the boiler is highly recommended. When installing the drain
pan, ensure that the installation does not restrict combustion air
flow.
Venting and ventilation
Consider venting restrictions caused by windows, doors, air intakes,
gas meters, foliage and other buildings, and select a location that
requires minimal venting.
When considering a adequate venting and ventilation, ensure the
following:
•
Maintain a minimum clearance of 4 feet (1.2 meters) from
heating and cooling vents.
•
Maintain proper clearances from any openings in the building.
•
Install the boiler with a minimum clearance of 12 inches
(300 mm) above an exterior grade or as required by local codes.
•
Install the exhaust vent in an area that is free from obstructions
and does not allow the exhaust to accumulate.
•
Do not enclose the vent termination.
•
Do not install the boiler where moisture from the exhaust may
discolor or damage walls.
•
Do not install the boiler in bathrooms, bedrooms, or any other
occupied rooms that is normally kept closed or that is not
adequately ventilated.
For more information about venting, refer to "Installing a Vent" on
page 29.
