3.3.1 Best installation conditions
Below are some factors to consider for best installation conditions:
Install the boiler in areas where the combustion air source is not subject to chemical fouling or
agricultural vapors. Exposure to corrosive chemical fumes such as chlorinated and/or
fluorinated hydrocarbons can reduce the life of a boiler. See list of
. For this reason, do not use the indoor air venting option (using air surrounding the
boiler) in a laundry room. Similarly, ensure any direct vent air source is not near a clothes
dryer exhaust terminal. Avoid agricultural applications where the boiler and/or the intake air
source are affected by ammonia and/or dust.
Avoid installing a boiler where water leakage will cause damage; for example, above
carpeting. If unavoidable, install a suitable drain pan under the appliance.
Vent location
- An important consideration is managing the impact of the steam plume
normally at the exhaust terminal of a condensing boiler. Generally, intake and exhaust pipes
should terminate at a rooftop or sterile wall location to maximize customer satisfaction. Keep
exhaust plumes well away from all building air intakes including those of neighboring
properties. Refer to
and
in
Sidewall vent termination on page 32
The minimum clearance requirements for combustible materials (see
).
For adequate servicing, we recommend a minimum 24" clearance at the front and 6" above
the boiler. Check local codes for additional access and service clearance requirements.
At a new construction site, or when renovating:
Protect the boiler from drywall dust or other construction related contaminants.
Ensure combustion air is drawn from a
clean
source (e.g., outdoors).
Isolate the boiler from interior dust sources.
3.4 Mounting the boiler
You must attach fasteners to solid material capable of supporting the combined weight of the boiler
and piping assembly components. Boiler weight – without water, system piping and components –
is approximately 113 lbs / 51 kg.
1.
Attach the support bracket (supplied) to the
wall studs using
¼" x 2½"
long lag screws
with flat washers.
2.
Hook the boiler tab (located on
back of boiler) over the support
bracket flange.
