Remington kerosene heaters are available in cabinet style, radiant heat, and forced air models. The forced air type of Remington heater extracts kerosene from the fuel tank and delivers it to the nozzle in the burner head. It's then sprayed in a fine mist into the combustion chamber to mix with air. When problems occur with any type of Remington heater, you can often address them yourself before taking the heater into the dealer.
Rinse the fuel filter in clean 1-K kerosene if the heater fires up but shuts down quickly. Also, clean or replace the nozzle and photocell. Use a cotton swab dipped in alcohol or water on the lens of the photocell and clean the nozzle with compressed air.
Add fresh kerosene to the heater and clean or replace the fuel filter and nozzle if the heater will not turn on. Remove the spark plug and then clean the terminal with a wire brush.
Add fuel to the tank if the heater makes a grinding noise. Grinding indicates air in the pump and adding fuel will remedy the problem.
