4 1. About a Natural Draft Diesel Heater A Dickinson diesel heater has many advantages to other heating appliances. They can be run on no power but has a 12v draft assist fan to provide draft assistance. Our heaters are equipped with simple but reliable internal components including a gravity feed oil metering valve to a vaporizing oil burner where the fuel vaporizes by natural draft to burn a beautiful clean fire in the viewing combustion chamber. A vaporizing oil burner is designed to transform oil to a vapor state and then burn the vapor. Vaporizing is achieved by the oil reaching 465 F....

5 VERY IMPORTANT: Unrestricted permanent fresh air inlet required to draw in outside air needed for correct operation. Fuel must be filtered and not exceed a pressure of 4 psi or a fuel pressure regulator must be used to avoid dangerous flooding (Dickinson part# 20-003). A barometric damper must be installed to help regulate the draft. A barometric gives you more control in the “fuel to air” mixture needed for correct operation. The valve controls the fuel whereas the fan increases the air and the barometric decreases the air (See Pg. 9). Install a CO alarm. 3. Ventilation Do NOT operate...

6 able to get your heater without sooting. A CO alarm should be installed in the boat. We also recommend the Dickinson high heat shut-off #02-210. 4. How Does the Chimney affect the Heater? The heater does not create the draft for a natural draft appliance to operate; it is the chimney that creates the draft for operation. The purpose of a chimney is to take the combustion products (smoke and gasses) from the appliance to the atmosphere outside your boat, and at the same time, to draw air in for combustion into the appliance. This movement of combustion air and exhaust is called draft. In...

7 3. Competition for available air. Third, there must not be too much competition from other devices in the boat, such as exhaust fans, a large engine or air-exchange systems. If something else is sucking the air out of the boat, the chimney might not be powerful enough to overcome it, and exhaust might be drawn into the boat from the chimney. 4. Proper chimney design. And finally, a chimney must be designed to accommodate the volume and type of exhaust being emitted by the appliances it serves. This involves correct sizing, adequate height, and proper construction. See the “Chimney Pipe”...

8 ceramic tile. The back of the heater and the first length of chimney pipe should also be lined with such material. See diagram on pg 8. Safety Clearances Above- 30”, In front- 18”, Sides- 12”, Below- 6” Facing Direction The heater ideally should face the bow or stern of the boat, particularly on a sailboat. Fuel is gravity fed from the oil metering valve into the burner so if the valve should drop below the level of the burner, the fuel would not flow uphill into the burner, which will put out the fire. In a beam-facing installation, the oil metering valve may have to be relocated to the...

9 Mounting There are holes provided in the feet of the heater to allow appropriate fasteners to secure it to the floor. The Newport model has the appropriate brackets to secure the heater to the bulkhead. The drip tray will then fit under the bottom of the heater. *The Newport bulkhead heater must be secured with the rear mounting brackets supplied. * All other model heaters must be secured to the floor through the bolt holes in the legs. **REMEMEBER: remove all protective plastic on ALL parts of the heater. Chimney Pipe The location and configuration of the chimney stack is very important...

10 Lofoten model heater Part# 17-001: 4” x 22” stainless pipe with barometric Part# 17-010: 4” x 7” stainless pipe with barometric The barometric damper should be installed in oil and solid fuel heaters. The purpose is to maintain a strong draft without causing too much air to the “fuel to air” mixture. When the damper is adjusted, the draft is altered by allowing air to be pulled into the chimney by the air inlet on the damper and not pulled into the burner. This gives you more control. Having a barometric allows you to burn your heater at lower temperatures giving you the control to...
