GENERAL
FIRE HAZARD. Since heaters are capable of devel-
oping high temperatures, extreme care should be
taken to:
A.
Locate on vertical wall with length of heater positioned horizon-
tally. HVT models must be installed with thermostat at right end;
B.
Avoid mounting into a wall recess since such mounting interferes
with free air circulation, increases heater temperatures, and pre-
vents proper thermostat operation on HVT models;
C.
Mount heaters with a minimum clearance of 24” above floor level
or from adjacent wall;
D.
Keep all combustible materials a minimum of 4” from front and
top of heater.
1.
Remove screw from each end and remove perforated cover.
2.
After feeding electrical wiring through opening in back of heater
(See WIRING section), mount back of heater to wall with four
screws (HVT models-5/16” diameter holes on 5” x 25-7/8”) (EH
models 9/32” diameter holes on 5x12-1/2” centers) through back
of heater. Leave one pair of end screws snug, but not tight, to avoid
expansion noise due to binding.
