172 INSTRUMENTS AND CONTROLS
WARNING
The parking heater is a very hot object.
DO NOT touch the heater when it is in
operation or shortly thereafter. Touching
a heater may cause burns to exposed skin.
CAUTION
The heater air inlet is located in the
bunk wall in front of the heater. DO
NOT attempt to put small items or store
flat items between the bunk and the
cabinet/refrigerator. The air intake can
be blocked which causes the heater to
overheat and shut down.
The parking heater is a diesel fuel burner that heats the air in the cab. Air is taken from
the cab and returned heated. Combustion air and exhaust is taken from, and released to
the outside air.
To safeguard from the heater operating after a turnover accident, there is a fuel shut-off
valve in the fuel delivery system.
