What to do if my Pinnacle HEAT-STREAM HS-45-KFA won't turn on and shows “E1”?

If your Pinnacle Heater isn't starting or the motor cuts off quickly, and the lamp flickers with an "E1" error, here's what you can check: * Ensure the fuel tank has enough fresh kerosene. * Adjust the pump pressure. * Inspect and clean or replace the spark plug if it's corroded or has an incorrect gap. * Clean or replace the fuel filter if it's dirty. * Clean the nozzle if it's dirty. * Rinse the fuel tank with fresh kerosene if there's moisture in the fuel. * Check the electrical connections between the transformer and circuit board. * Make sure the ignitor wire is connected to the spark plug. * Replace the ignitor if it's defective.
