MOUNTING AND WIRING
NOTE: Electrical wiring is to be sized in accordance with National
Electric Code and local codes using at least 75°C type RH, THW
or equivalent insulated wire. See chart located on page 3 for
amp. loads.
1.
Locate on vertical wall with length of heater positioned
horizontally.
2.
When selecting a mounting location, the following minimum
distances must be observed to insure proper operation.
a.
Six (6") inches (152mm) from bottom of heater to floor.
b.
One (1.5") inch (38mm) from wall or other obstruction to
the right or left side of heater.
3.
Do not mount heater in a recess, since such mounting
interferes with free air circulation, increases temperature and
prevents proper thermostat operation.
NOTE: Unit is shipped with non-tamper resistant screws securing
front cover. Remove screws and discard.
4.
Mount the rear panel assembly of the heater to the wall using
the 11/32" (8.7mm) diameter holes (bolts and wall anchors to be
supplied by customer).
5.
Install the perforated cover by hooking the top edge of the
cover over the top edge of rear panel.
6.
Attach the bottom lip of the perforated cover to the wall using
the 1/4 - 20 x 1" tamper proof screws provided (Wall anchors
to be supplied by customer).
7.
Electrical wiring must be brought into heater through 1-3/32"
(27.8mm) diameter hole located in the rear panel.
8.
Grounding conductor must be connected to the green pigtail
lead.
9.
Make the proper connections following the wiring diagram.
Install disconnect switch cover assembly with (2) #8 x 5/8"
tamper proof screws (provided).
10. Adjust thermostat to the desired setting. Install top access
cover with (4) #8 x 5/8" tamper proof screws (provided).
OPERATION AND MAINTENANCE
To assure efficient operation, follow the simple instructions listed
below.
TO CLEAN HEATER
Because of the convection heating principle which depends upon
a circulation of air through the finned element, dust particles will
periodically be deposited between the fins, and should be
removed occasionally for maximum efficiency of the heater. With
front cover removed, a vacuum cleaner with proper attachments
can easily be worked along the top and bottom of the finned ele-
ment to clear it of dust deposits.
TO REPAINT, IF DESIRED
The baked enamel finish was chosen to blend with interior decors.
If you wish to repaint the heaters, use high quality household
enamel. No primer is necessary. Do not use rubber base paint.
Paint heater front cover only. Do not paint heating element.
HAZARD OF ELECTRIC SHOCK. DISCONNECT ALL
POWER BEFORE ATTEMPTING TO SERVICE THE
HEATERS.
