Remark:
Flue requirements may affect location. Consult section
7 before making a final determination.
Warning:
If touched, the vent pipe and internal heater surfaces
that are accessible from outside the heater will cause
burns. Suspend the heater such that these components
cannot be touched.
Use the minimum clearances in section 5 and the throw data
in the technical data table of section 6 when determining
where to suspend the heater.
For best results, the heater should be placed with certain rules in
mind. Always ensure that minimum clearances are maintained.
Locating a unit heater above the maximum recommended
height can result in significant air stratification. When possible,
heaters should be arranged to blow toward or along exposed
wall surfaces.

Suspended heaters are most effective when located as close to
the working zone as possible, but 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.
LOCATION HEATER
Caution :
Do not locate the heater where it may be ex-
posed to water.
At those points where infiltration of cold air is excessive, such
as at entrance doors and shipping doors, it is desirable to locate
the unit so that it will discharge directly toward the source of
cold air, typically from a distance of 4.5 to 6.0 meters or install
a downflow unit over the door opening.
The presence of chlorine vapours in the combustion air
of gas-fired heating equipment presents a potential corro
-
sion hazard. Chlorine, found usually in the form of freon or
degreaser compounds when exposed to a flame will precipi
-
tate from the compound, and go into solution with any con-
densation 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
exhausters 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.
Where chlorine vapours are prevalent heaters with special
grade 316 A1SI stainless steel heat exchangers are recom-
mended.
Hazards of Chlorine - apply to the location of the
combustion air inlet
