HEATER LOCATION INSTRUCTIONS
rrange units so their discharge air streams:
a. are subjected to a minimum of interference from columns,
machinery and partitions;
b. wipe exposed walls without blowing directly at them;
c. are directed away from room occupants in comfort heating;
d. are directed along the windward side when installed in a
building exposed to a prevailing wind.
Locate thermostats approximately 5' (1524mm) above the floor
on interior partition walls of posts, away from cold drafts, internal
heat sources and away from heater discharge air streams.
Small rooms can be heated by one unit heater.
Large rooms require multi-unit installations. Number and capac-
ity of units will be determined by volume of building and square
feet of floor area to be heated. rrange units to provide perime-
ter air circulation where each unit supports the air stream from
another. MOUNTING THE HEATER
GENERAL
The heater may be mounted to discharge the heated air either
horizontally or vertically. When the heater is mounted for vertical
discharge, it is recommended that the heater be positioned so
that the access door will open away from the wall to provide
greater access to the wiring and control compartment. If the
heater is to be mounted with the access door facing a wall, the
heater must be mounted far enough from that wall to allow full
opening of the access door (a distance approximately equal to
the width of the heater ... check clearance before installing).
Refer to Table 1 for wall and ceiling clearances before mounting
heater.
The heater may be mounted for either vertical or horizontal dis-
charge by the use of threaded rods. (Refer to Table 2 for thread-
ed rod sizes required.) Observe the detailed procedures in the
following installation instructions.
The heater may also be suspended from the wall or ceiling by
means of an optional mounting bracket (type HUH B or
HCMB) which permits horizontal pivoting of the heater.
fter the heater is installed, the louvers may be positioned to
direct the heated air in the desired direction. When the heater is
installed for horizontal discharge,the louvers should direct the air
either straight ahead or downward. Directing the air upward may
cause the heated air to remain in the ceiling area and waste
energy.
