Good to know

  • Install the heater inside the vehicle or in a protected compartment and route the exhaust and combustion air intake outside the living space. Professional installation is recommended.
  • Use a CO detector in any sleeping area heated by a fuel-burning heater.
  • In freezing temperatures use winter-grade diesel to prevent fuel gelling.
