The draft above the top of the fire will be aprox -.05 inches of water column, should you
have a draft meter, however adjusting the damper as above should get you close enough.
Dickinson can supply you with a stainless steel thru-deck fitting for your pipe
installation. The thru-deck fitting includes a stainless steel dress ring for the interior of
the cabin and a rubber (neoprene) gasket easy mounting. Depending on the contour or the
angle of the cabin top, you may need to make a hardwood spacer block. One surface of
the block would be a level plane to mate to the deck cap. The other would match the
angle or contour of the cabin top. A hole through the center of the block would be 2
inches greater in diameter than the flue pipe.
The Dickinson DP or H style flue caps are recommended. 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 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. Dickinson part # 20-003.
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 3/8" flare fitting.
