INSTALLATION
The heaters may be mounted at any convenient height above
floor. The minimum spacings, shown in Figure 4, should be main-
tained to adjacent walls and ceiling. If floor heat is desired, do not
mount higher than 8’ to 10’ above floor.
Controlling thermostats to individual heaters should be mount-
ed at shoulder height on inside walls or columns and clear of the
discharge air stream of the unit. Allow at least 4’ in front of heater
for air stream to discharge freely. Do not mount mercury type ther-
mostat directly on units, vibration could cause malfunction.
Heater may be mounted on a shelf or stand from the bottom. Be
sure the mounting clearances are maintained and that bottom of
unit has at least 1’ clearance underneath it. This is necessary for
good air circulation and servicing of heat exchanger. All mounting
methods must allow for removal of front cover.
The mounting and anchoring provisions must take into account
the unit vibration and cantilevered loading when wall or pole
mounted. One of the mounting kits, shown in Figure 5, 6 and 7,
must be used whenever possible.
