Shut Down Instructions
If the heater is to be shut down for cleaning, mainte-
nance, or repair, follow steps 1-3. Otherwise, simply
adjust thermostat to “Off” or “No Heat” or put the HEAT/
VENT switch to the OFF position.
1. Turn thermostat dial to lowest temperature setting.
2. Allow heater to perform it post purge cool down
mode.
3. Unplug cord from outlet.
DO NOT DISCONNECT THE ELECTRICAL SUPPLY
UNTIL THE MAIN FAN MOTOR HAS CYCLED OFF
FROM COOLING THE HEAT EXCHANGER
Note:
During normal operation, if either the thermostat
cycles the heater off or the selector switch is
put in the OFF position, the main fan motor will
continue to operate. This is the cool down post
purge of the heat exchanger. The high limit LED
will flash during this process. After 3 minutes of
post purge, the heater will shut-off.
Cleaning Instructions
1. Before cleaning, disconnect electrical supply.
2. The heater should have dirt or dust removed
periodically:
a. Before each use give the heater a general cleaning
using compressed air or a soft brush or dry rag on
its case and internal components. At this time, dust
off the motor case to prevent the motor from over-
heating.
