6. Fuel System Installation
For efficient and safe operation of the stove, follow all recommendations for
properly installing the fuel system.
DANGER: Never use gasoline in the stove. Use only #2 diesel, #1 stove oil
or kerosene. The valves are factory calibrated to #2 diesel; if #1stove oil or
kerosene is preferred, the valves can be re-calibrated to suit those viscosities.
*** If in colder temperatures it may be wise to burn kerosene or add fuel
additives to your fuel to keep the fuel viscosity thin for correct operation. In
some cases, a valve with a higher flow rate may be needed.
Fuel Supply & Overflow Feature
The fuel supply fitting on the oil metering valve is a 1/8” NPT female fitting
and the overflow is also 1/8” NPT female fitting. ACR (refrigeration) copper
tubing should be used for the first 3 feet of fuel line from the stove.
Approved hose can be used for the remainder of the installation. Run the
fuel lines as straight as possible to avoid air locks. Check all connections for
any leaks.
The overflow safety feature is designed to allow the controlled escape of
fuel from the stove in case of over pressurization. If dirt, debris, or too much
pressure gets into the needle and seat inside the valve, the fuel will rise and
overflow out of the valve and away from the stove. It is common to get a
few drips now and then from the movement in rough waters, however, more
then a few drops of fuel from the overflow indicates the need to service and
clean the valve.
Under NO circumstances plug the overflow fitting!!
A fuel line must be
taken from the overflow fitting back to the main tank if the fuel is supplied
from the main tank. If the fuel is supplied from a day tank, then run the
overflow line to a container away from the heat source. The fuel overflow is
a gravity escape. Do not install the overflow line so that is goes up or in
loops as this will cause an air lock and block the fuel from escaping. Plastic,
rubber or copper tubing may be used for the overflow line.
Note: If the your fuel tank vent or fill tube is higher than the valve of the
stove, and the overflow of the stove goes back to the main tank, there may
be a chance when re-filling that the fuel will back flow up the overflow and
out of the valve. For this reason a manual shut-off will need to be teed in the
