OPERATING INSTRUCTIONS
1. This heater must be properly installed before it is used.
2. When using an external thermostat, refer to the installation
and operating instructions provided with thermostat.
3. On initial start up and check out, before heater is energized,
rotate thermostat shaft to the full counter-clockwise (lowest
heat) setting. Connect power to the heater and check to ver-
ify the heater is not heating. If heating, disconnect and
check wiring.
4. Rotate thermostat shaft to the full clockwise (CW) (max heat)
setting and allow heater to operate for at least 5 minutes and
verify it is heating.
5. Allow heater to operate until room ambient reaches desired
comfort level and then slowly rotate thermostat shaft counter-
clockwise (CCW) until you hear or feel a click. This will pro-
vide a set point to allow the thermostat to cycle the heater on
and off to maintain this approximate temperature. Some
slight adjustments may be necessary to fine tune the heater
to provide the most desired room comfort. To increase time
heater stays on and increase the room temperature, slightly
rotate the thermostat in the CW direction. Likewise, to
reduce the room temperature, slightly rotate the thermostat
in the CCW direction.
MAINTENANCE INSTRUCTIONS
For efficient and safe operation and to extend the life of the
heaters, they should be cleaned and inspected for damage at
least annually (preferably at the beginning of the heater season)
or more often in dirty environments. Other than cleaning, your
heaters require no other preventative maintenance. The user
can perform some basic cleaning of the heater. All other servic-
ing is to be done by qualified service personnel.
To Clean Heater
1. Heater cabinet may be cleaned using a damp cloth to
remove dust that may have accumulated on surfaces. Do
not use harsh cleaners and waxes on surfaces since these
could damage the finish or discolor in use.

remove dust and lint that may have accumulated inside
heater around element fins. If heater must be dissembled for
cleaning, removed the screws securing front cover and
remove front cover to allow for access to inside. Use care
when cleaning element fins to avoiding damaging fins.
3. After cleaning and servicing, replace front cover and screws
