Location of the heater
If touched, the vent pipe and
internal heater surfaces that
are accessible from outside the
heater will cause burns.
Note: Flue requirements may affect
the heater location. Consult the flue
requirements section prior to making a
final decision on the location.
For best results, the heater should be placed
with certain rules in mind.
• Always ensure that minimum clearances
are maintained.
• When possible, heaters should be arranged
to blow toward or along exposed wall
surfaces.
• Care should be exercised to avoid directing
the discharged air directly on to room
occupants.
• Partitions, columns, counters, or other
obstructions should be taken into
consideration when locating the unit
heater so that a minimum quantity of
airflow will be deflected by such obstacles.
When units are located in the centre of the
space to be heated, the air should be
discharged toward the exposed walls. In large
areas, units should be located to discharge air
along exposed walls with extra units provided
to discharge air in toward the centre of the
area. For optimum results heaters are best
used in conjunction with recirculating air fans
suspended at high level.
Do not locate the heater where it
may be exposed to water.
Hazards of Chlorine - apply to the location
of the combustion air inlet. The presence of
chlorine vapours in the combustion air of gas-
fired heating equipment presents a potential
corrosion hazard.
Chlorine is usually found in the form of Freon
or degreaser compounds when exposed to a
flame will precipitate from the compound, and
go into solution with any condensation that
is present in the heat exchanger or associated
parts.
The result is hydrochloric acid which readily
attacks all metals. Care should be taken to
separate these vapours from the combustion
process.
This may be done by wise location of the unit
flue and combustion air terminals with regard
to exhauster’s or prevailing wind directions.
Chlorine is heavier than air. Keep this fact in
mind when determining installation location
of the heater in relation to building exhaust
systems.
