IMPORTANT!
It is extremely important
that you verify that the
electrical supply wires
are the same voltage as
the heater (i.e. 120 volt
heater to 120 volt power
supply and 240 volt
heater to 240 volt power
supply). If replacing an
existing heater, check
the labels of the old
heater and replace
using the same voltage.
Hooking a 240 volt
heater to a 120 volt
power supply will
drastically reduce the
heater's output.
Hooking a 120 volt
heater to a 240 volt
power supply will
destroy the heater.
Connecting your
heater to an
incompatible power
supply will void
the warranty.

How to operate your heaters
Maintenance
As needed or every six monthsminimum. Failure to do so will void warranty
The heater is protected by two temperature limiting controls. The first is a high temperature reset
switch, designed to open the heater circuit when excessive operating temperatures are detected.
Further protection is provided by a backup over-temperature switch, which will permanently open
the heater circuit in severe over-temperature conditions, or in the event of component failure. If
this occurs, the heater must be replaced.
About the heater temperature-limiting controls
If the manual-reset limit control has opened the heater circuit due to excessive operating
temperatures, the heater will not work until the limit reset button is pressed. After allowing the unit
to cool for 10 minutes, clean the heater as instructed in the Maintenance section above. Use a
narrow, non-conductive object to access the reset button through the upper-right section of the
grill. Press GENTLY, and be sure to listen and feel for a click indicating it has been reset.
Note that resetting the manual reset limit control may not restore heater operation if a severe
over-temperature condition has occurred. See the following Troubleshooting Chart for more
information.
