The H style flue caps are recommended, especially if the balanced draft system is not
used. The location of the flue cap above deck must be clear of any immediate obstruction
that may cause unusual air movement or turbulence. CAUTION : The Flue Cap gets hot
when the stove is operating.
Note: The caps, pipe, and deck fitting may appear to have a rusting look. This is caused
by operating the heater too rich. This will produce soot that will leave carbon deposits on
the stainless steel giving the appearance of rust, much like cleaning stainless steel with a
steel SOS pad. The stainless can be cleaned with a scotchbrite pad to remove the rusty
looking surface.
Fuel Supply
Fuel is supplied to the oil-metering valve of the heater/stove from a gravity feed tank or by a
low-pressure pump direct from the main fuel tank. The fuel metering valve is rated to an
incoming fuel pressure of 3 psi. If fuel supply exceeds 4 psi a pressure regulator will be
needed in the supply line.
Install a gravity tank no higher than 8 feet above the valve of the heater without a
pressure regulator.
Install a low pressure fuel pump with a pressure no greater than 4 psi (2.5-3 psi is
ideal)
Install a low pressure fuel regulator set to within a range of 2.5-4 psi. When a gravity
tank is used a minimum head of fuel 12" (30.48 cm) above the fuel level marked on the
side of the oil-metering valve is required to operate the oil-metering valve. The gravity
feed tank must be vented and all fuel lines must be as straight as possible to avoid air
locks. The fuel inlet is a 1/8 npt female thread .
#15078 FRD-2 3 PSI FUEL PUMP
&
#15079 FRD-HD c/w REGULATOR FUEL PUMP
•
These are 12 volt DC pumps. The factory spring pressure for the #15078 FRD-2
pump is set at 3 PSI (max 6 ft. lift).
•
The #15079 FRD-HD pump has a stronger pressure spring that will draw the fuel
higher (max 15 ft. lift) but will need the regulator to adjust the pressure down to 3
PSI before the fuel goes to the oil metering valve.
•
You must use a fuel oil filter in your installation before the pump to keep debri
from plugging up the 3 check valves inside the pump.
