INTRODUCTION You have just purchased the most advanced diesel cabin heater available. It is designed and built by sailors who know the need for dependable, safe, dry heat and it represents years of experience in the marine-heating field. Installation and operation is straightforward. After you have completely read the instruction manual. FIRST LET’S ANSWER A FEW BASIC QUESTIONS: Q. What is a Balanced Draft? A.
IMPORTANT When filling the system for the first time, we suggest tapping the metering valve slightly. This will free all moveable parts due to storage and prevent oil from escaping through the overflow outlet. Also, to remove any air that may get trapped in the fuel hose between the valve and the burner, lift the valve knob up and down a few times and flex the fuel hose. This will act as a pump and force any air that may be trapped in the fuel hose to escape.
BALANCED DRAFT SYSTEM The Balanced Draft System is optional; it is not required but can be added later if you wish. The Balanced Draft has 2 major advantages. In most cases it will eliminate “back drafting or down drafting” (Page 8) and allows the heater to use outside air for combustion rather than cabin air. This increases the safety and efficiency of the heater. The balanced draft system can be mounted on all our heaters No. 100, 120, 170, and 180. Unfortunately it can not be mounted on the No.
THINGS TO CONSIDER 1. Minimum flue pipe length is 3 feet for the 100 and 120, 4 feet for the 170, 180, 190, 200 and 250. This is the absolute minimum. 2. The maximum angle of any bend in the stack is 45 Degrees. 3. If installing the Balanced Draft, the air intake must be mounted within a 3-foot radius of the Rain Cap on the cabin top for proper operation. 4. If installing a heater in a sailboat and planning to use while under heel, see “Sailboat Mounting” (page 6). 5.
SAILBOAT MOUNTING When installing the heater in a sailboat, it is important that the metering valve and the burner are both in line with the keel to permit proper functioning of the heater when the boat heels. If the heater is installed with the window facing fore or aft, the metering valve and burner will already be in line with the keel and no additional actions are necessary. If the heater is installed with the window facing port or starboard, the metering valve must be repositioned.
2. ELECTRIC FUEL PUMP, this type of installation is a very common one, the advantages are; it’s less expensive than a gravity tank and you can have full capacity of your main fuel tank. The disadvantages are; power draw, noise, and loss of the heater in the case of the pump failure. 3. Some installations use both methods, a gravity tank to supply the heater and an electric or manual fuel pump to fill the gravity tank. Let’s do the installation of the gravity tank first.
ELECTRIC FUEL PUMP INSTALLATION The maximum pressure that our metering valve (carburetor) can withstand is 3 PSI. If more than 3 PSI is used, fuel will flow out of the overflow outlet. In other words, the float in the metering valve does not have enough buoyancy to close the needle seat and thus shut off the flow of fuel. We recommend the Walbro fuel pump No. 2403-1. This is an adjustable pressure fuel pump that comes preset at 2 1/2 PSI. Therefore, no adjustment is required. Walbro makes another pump, No.
“BACK DRAFTING” OR “DOWN DRAFTING”: The reason this can occur is because of changes between inside and outside of your boat, caused by windage coming from the sails or across the flying bridge and causing air turbulence on your deck, which creates a high pressure area around the Rain Cap (exhaust pipe), and this can slow, stop or reverse the “drafting “ of the heater or even extinguish the flame. Because the heater is hot, the flame may re-ignite when the fuel flows into the burner.
HEATER LIGHTING PROCEDURE MATERIALS To light the heater, you will need the following: -A piece of toilet tissue or facial tissue (no paper towels!) -Matches or a lighter. - A 1 oz. container HEATER LIGHTING STEPS 1. On the 100,120 and 170 open the small door inside. On the 180, 190, 200 and 250, open the top or lid. 2. Pour 1 oz. of kerosene or alcohol into the burner.
FIGURE 8. STAGES OF BURNER IGNITION. NOTE: Illustrations are for the 100 and 120. The 170,180, 190, 200 and 250 have a four postevaporating stem. STAGE 1 A single flame rises up the side of the burner from the burning tissue. Some light smoke from the rain cap is to be expected. STAGE 2 Fuel is starting to vaporize and burn. Some light smoking will still be detected. STAGE 3 In this stage, the flame is now up out of the burner with the base of the flame at the level of the burner ring.
METERING VALVE ADJUSTMENT: Our metering valve is a very simple device and will require little maintenance. However, because of the different fuel viscosity’s, some adjustments will be necessary. See “Trouble Shooting” if necessary (page 22). STORAGE When storing the boat heater for long periods e.g. 2 or more months, while the stove is “burning” turn off the fuel supply, and leave the metering valve in “on” position.

CLEANING THE NO. 100 AND 120 Depending on the quality of the fuel that you use and how often you use the heater, some carbon may build up around the legs of the vaporizing stem and on the inside of the burner. You may clean the burner by reaching in through the door or by removing the burner.
CLEANING THE NO. 170. Depending on the quality of the fuel that you use and how often you use the heater, some carbon may build up around the base of the vaporizing stem and on the inside of the burner. You may clean the burner by reaching in through the door or by removing the burner.
CLEANING THE NO. 180, 200 AND 250 STOVE. Depending on the quality of the fuel that you use and how often you use the heater, some carbon may build up around the burner oil inlet and on the inside of the burner. For the 180, it is much easier to clean the heater if you remove it from the boat. Then remove the shroud from the heater. Then separate the upper part of the burner from the bottom, by removing the 4 screws.
THE DRAFT ASSIST FAN (OPTION) If you decide not to install the “Balanced Draft” System and you experience “back drafting” or “down drafting” (see Page 9), the Draft Assist Fan is an option that may help solve the problem. When using the Draft Assist Fan you must attempt to match the velocity of the fan to the velocity of the wind in the down draft. The Draft Assist Fan mounts on the air intake (bottom) of your heater. You must remove the “Draft Regulator” in order to install the Draft Assist Fan.
THE DRAFT REGULATOR CUT-AWAY VIEW OF THE DRAFT REGULATOR STANDARD ON ALL HEATERS- (NOT ON NO. 190, 200 AND 250 STOVES) The Draft Regulator is located at the base of the heater and is provided as standard equipment on all heaters-No. 100, 120, 170, and 180. If you have too much exhaust pipe, you will have too much draft and the flame will be drawn down into the burner. This will result in soot on the window, in the burner and ultimately in the exhaust pipes.
IMPORTANT!!! IMPORTANT!!! IMPORTANT!!! At any time and after maintenance on the burner be sure to: 1. Insert the burner ring with the flange down. The burner ring must be seated fully down. 2. On the 100 and 120 heaters, insert the brass vaporizing stem flat on the bottom of the burner base, making sure all four feet are flat on the bottom of the burner base. The legs may not be flat after cleaning, therefore be sure to straighten them so the feet are flat on the bottom of the burner base.

TROUBLE SHOOTING. Theory of Operation Note: The fire must always be burning above the ring on the 100 and 120 heaters! Reason: In order for the heater to not smoke, we have designed our burner to burn fuel vapors diesel, kerosene or stove oil. To do this, the flames surround the brass vaporizing stem above the burner ring. The stem conducts heat to the base of the burner and heats it. When the fuel enters the burner, through the hole in the center of the base of the burner, it immediately turns to vapor.
Problem #2: The flame is below the ring. Solution: Increase the flow of fuel into the burner. This is done by turning the knob on the metering valve (carburetor) to a higher number. Advance one or two numbers and then wait approximately five minutes for the burner to stabilize. If the flame is still below the ring advance one or two more numbers. Continue this process until the flame burns above the ring.
Problem #3: When you turn the knob on the metering valve to “OFF”, the fuel continues to flow into the burner. Solution: Refer to the drawing on Page 14 of the Instruction Manual. Note the “O” ring in the metering valve that shuts off the flow of oil, Item “O”. Check to see that the “O” Ring is intact - e.g. not broken or missing or crimped. To check the “O” Ring you must disassemble the metering valve. Note: be sure that the shut off to the metering valve is turned off.
