5. Venting is improper. Follow the manufacturer’s recommendations concerning proper venting. Failure to do so can result in heat building up in the heater until the safety thermostat contacts open and shut the heater off. 6. Nozzle is dirty. If dirt reaches the nozzle, the spray can be adversely affected and cause a shut down. If possible observe the spray pattern and clean the nozzle as needed.

Heater ignites but flame is excessive Causes: 1. Fuel pump pressure is too high. 2. Nozzle is worn. 3. Incorrect fuel. Solutions: 1. Fuel pump pressure is too high. Attach a high pressure fuel gauge to the fuel pump and check the pump pressure. Adjust the pressure to the manufacturer’s specifications with the adjustment on the fuel pump.
