Blank Sections
Blank sections, if any, are installed in the same manner as the
heaters.
OPERATION INSTRUCTIONS
1. After heater(s) are completely assembled and installed, set
thermostat or operating controls for NO HEAT and energize
the heater circuit (s). Verify the heater(s) are not producing
heat.
2. Adjust thermostat or operating control to call for heat. Allow
heater(s) to operate for a few minutes and verify all heaters
are producing heat.
Note: During initial start up, heaters may exhibit a new smell
and possibly some slight smoke from the manufacturing
residues on the heating element. Allow heaters to operate for
approximately 30 minutes to dissipate these residues.
Ventilating the area may be desired.
3. To set thermostat or operating controls to maintain desired
comfort level, allow heaters to operate until room ambient
temperature reaches the desired level. The thermostat or
operating control can then be adjusted to maintain this tem-
perature.
Note: When built-in thermostat and/or disconnect switch is/or
provided, access to these controls will be through grille openings
at either end of the heater. To rotate the thermostat shaft will
require a small flat blade screw driver. The disconnect switch is
a rocker switch that can be operated with the same screw driver
or tool through the openings.
4. If built-in thermostat is provided, after room reaches desired
comfort level, rotate thermostat shaft counterclockwise until
the thermostat clicks. This should allow the thermostat to
cycle the heater on and off to maintain this temperature.
Rotation in the clockwise direction will allow the heater to
remain ON MORE and will maintain a HIGHER room ambi-
ent. Likewise, rotation in the counterclockwise direction will
result in the heater remaining ON LESS and the room ambi-
ent will be LOWER. If remote thermostat or other types of
controls are provided, refer to the instructions provided with
these controls for proper operation.
IMPORTANT NOTE: These heaters are provided with a built-in
safety limit (Thermal Protector– see Fig. 8) to automatically turn
off the heater if it is blocked or otherwise overheats due to an
abnormal condition. The heaters should not be cycling off on
this safety control during normal use. If this is occurring, check
heater installation to assure it has adequate clearances and the
free airflow around heater is not restricted. If heater continues
to cycle on this safety control, discontinue using until it can be
inspected and/or repaired by a qualified electrician.
MAINTENANCE INSTRUCTIONS
Your heater will give your years of service and comfort with only
minimal care. The user can perform periodic cleaning of the
exterior cabinet, but all other interior cleaning and servicing
should be done by a qualified service person.
Note: For efficient and safe operation, airflow must not be
restricted in and around the heater. As air moves through the
heater by convection, dust and lint may accumulate in the
heater and around the heating element that needs to be cleaned
periodically. It is recommended that your heater be cleaned and
inspected for damage at least annually (or more often if
needed).
1. The exterior of the heater may be cleaned with a damp cloth.
However, do not use harsh cleaners, polishes, or waxes as
these may damage the surface or leave a residue that will
discolor.
2. To clean interior of heater will require the removal of the front
cover. To remove the front cover, disengage the top rear
snap-lock first. Use an “L” shaped tool, such as an Allen
Wrench, to lift up under the webs between the back row of
slots (See Fig. 7). Start at either end and lift up on the front
cover until the tension in the cover pulls the cabinet apart.
Continue moving along the length of the heater until the
cover comes off.
3. With front cover removed, a vacuum cleaner or compressed
air can be used to clear dust and lint from inside heater and
around the heating element. Fins are sharp and may cause
cuts so avoid contact by hands. Use care to not damage the
aluminum fins.
4. As a matter of normal maintenance, check remainder of
heater for damage or possible maintenance issues while
cover if removed and make any repairs needed.
5. Replace front cover as shown in Fig. 5 making sure it is
locked in position along length of heater. Restore power to
heater and verify it is operating properly.
1. Serious injury or death could result from electric shock.
Make sure electrical power supply circuit(s) coming to
heater is/are disconnected at main disconnect or service
panel before servicing this heater. Allow heater to cool
before cleaning to prevent a possible burn.
Note: More than one power source may enter heater.
Be sure all power is disconnected to heater before
cleaning or servicing.
2. Use care when cleaning element fins to avoiding damaging
fins. Note also that fins are sharp and may cause cuts so
avoid contact.
