*
Flames are orange and dirty creating soot on the window & deck
- The
flames are burning too rich, this to say too much fuel and / or not enough air.
Add air first by turning the fan on. Just add enough air to turn the flames
vibrant yellow and not lazy orange with black tips, however adding too
much air will burn off the fuel and the flames will end up below the top
burner ring. After a short time you will get to know what positions to set the
fuel and air to maintain the most heat with the cleanest flames.
*
Burner flooded with fuel
- Is caused by fuel entering the burner faster than
it is burning and is caused by increasing the fuel supply too quickly without
the use of the combustion assist fan.
Poor draft and/or ventilation.
*
Fuel is leaking out the overflow or the top of the valve - The overflow
line may have an air lock causing the excess fuel to back up into the valve,
or excessive pressure going into the valve.
*
Fuel isn’t getting to the burner - The fuel line may be plugged from the
valve to the burner. Disconnect the fuel outlet from the bottom of the valve
and let the valve drip fuel into a small container or cup. Next blow hard
through the fuel line so any debris will end up in the burner, then reconnect.
If the valve was dripping fuel and the fuel line is not plugged tap the copper
line to remove any air lock.
*
I am getting downdraft down my chimney pipe- The smell of diesel or
smoke coming into the boat may be caused by negative ventilation. The
chimney may not be getting hot enough to create a strong draft. Turn the fan
on to a very slow speed but balance the fuel to keep flames above the ring
Pg 18. Adjust the barometric flap so it is open between ¼ to 3/8.
*
There was an explosion inside my heater -This is caused by a downdraft
however the air is sucked in by a negative draft that actually blows out the
flames but is hot enough to re-ignite the hot vapor. Follow instructions for
downdraft.
*
My valve is turned to the OFF position and oil is still going to the
burner
- This is a broken O ring in the valve. See diagram.
