our combustion heaters:
The electrical wiring harness must be sufficiently dimensioned to prevent

overheating. The electrical wiring harness must be sufficiently insulated.
All power circuits must be protected with fuses or automatic circuit-
breakers.
The cables must be securely fastened and routed so that the lines are


ground without coming into contact with hot parts of the vehicle or the
load.
The exhaust system as well as the exhaust pipes shall be so directed or
