Trouble Shooting
-
No fuel in the bottom of the burner
Check the tank is vented or the pump has power and all shut-offs are open.
Disconnect the fuel outlet on the bottom of the valve, and let the valve drip into a
container to test if the fuel is getting into the valve.
Blow through copper fuel line to clear any obstruction into the burner before
reconnecting fuel outlet.
Check for air lock by tapping copper line when turning on the fuel for the first time
after reconnecting.
-
Hard carbon on the bottom of the burner
The burner is getting too much air and needs a higher fuel setting, turn down the fan
or turn off, open the barometric flap a little more.
-
Soot on the window, in the chimney or on the deck
The burner is getting too much fuel and needs a lower fuel setting, turn on the fan or
increase the fan speed, close the barometric flap a little.
-
Burner Floods
The burner is getting too much fuel when lighting the burner and needs more air to
burn off the fuel on start up. The valve may have been left on too long and too much
fuel was in the burner before lighting, or not turning the valve off during the
preheating of the burner. If the draft is extremely poor and smoke is coming out of the
heater into the cabin. For all these reasons the fan will add the air to burn off the fuel.
-
Cannot get the flames to burn above the top burner ring
The burner is getting too much air and needs a higher fuel setting, turn down the fan
or turn off, open the barometric flap a little more.

Fuel coming out the overflow or top of the valve
The fuel coming out the overflow indicates a problem with the needle and seat, or
float inside the valve,( refer to pg-9) for cleaning instructions. There may be too much
pressure in the fuel line to the valve. A pump with too high a pressure setting or a
large fuel tank will need a pressure regulator. The fuel will not come out the top of
the valve unless there is a back flow of fuel up the overflow line. Check for loops or
air locks in the line and the tank vent may be higher than the valve height.
