z TOWING
Before towing the Heater, inspect the trailer visually to ensure that the following
operations have been completed:
1.Hitch is securely attached to the towing vehicle (safety chain secured).
2.Verify that the fuel tank is completely empty.
3.Taillights are connected and operating.
4.Check for adequate tire pressure.
CLEARANCES AND LEVELING
Ensure that the heater is level. Maximum "out of level" must not exceed 10
degrees.
During operation, combustible materials must be kept a minimum of two feet
away from all sides of the heater; heater must be on a non-combustible floor. If
heater is equipped with tube storage, combustible material cannot be stored in
this area.
WARNING
If outside temperature is expected to rise above 32°F both discharge air ports
must remain unblocked to allow adequate cooling air flow.
RPM needs be decreased as outside temperature rises about 32°F. The heat
generating unit will overheat and shut down if these instructions are not followed.
