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.
