During the early stages of new home design, we recommend that proper
consideration be given to constructing a separate mechanical room dedicated to
gas- or oil-fired equipment including domestic hot water storage tanks.
The boiler must be located in a heated indoor space, near a floor drain, and as
close as possible to the wall.
Whenever possible, install boiler near an outside wall so that it is easy to duct the
venting system to the boiler.
Locate boiler on walls capable of supporting the weight of the boiler filled with
water (see section entitled "Technical Data" on page 68 for information required
for total boiler weight calculation). Ensure that boiler location does not interfere
with proper circulation of combustion and ventilation air of other fuel burning
equipment (if applicable) within the mechanical room.
The maximum room temperature of the mechanical room where the boiler is
located must not exceed 104°F/40°C.
IMPORTANT
Boiler operation in marine environments
(damp, salty coastal areas):
The service life of the boiler's exposed
metallic surfaces, such as the casing
and fan housing, is directly influenced
by proximity to damp and salty marine
environments. In such areas, higher
concentration levels of chlorides from
sea spray, coupled with relative
humidity, can lead to degradation of
the exposed metallic surfaces
mentioned above. Therefore, it is
imperative that boilers installed in such
environments not be installed using
direct vent systems which draw
outdoor air for combustion. Such
boilers must be installed using room air
dependent vent systems; i.e. using
room air for combustion. The indoor air
will have a much lower relative
humidity and, hence, potential
corrosion will be minimized.
