Installation COMBUSTION AIR Make-up outside air must be provided to furnace for proper fuel combustion. This is provided by openings to outside of building. These openings shall have unobstructed areas not less than the areas of the flue pipe. See Figs. 25, 26, 27 IMPORTANT: Outside air is needed to replace air used by the burner and wood combustion process. Outside air is required to replace air used for taking the by-products of combustion out the chimney.
Installation FURNACE LOCATED IN CONFINED SPACE When the furnace is in utility room, install two open grilles. (See Fig. 28.) Place them in a wall or door opening to the rest of the house. One grille will supply combustion air. Locate it near the floor. The other grille is for ventilation. Locate it close to the ceiling. Each grille must have a free area. It should be not less than one square inch for each 1000 BTU/hr. of the total input rating of appliances in confined space.
Operating Instructions OIL FIRING THE UNIT To start the oil burner on a new installation 1. Check to make sure there is oil in the storage tank. No. 2 fuel oil may be used if tank is in the basement or buried below ground. No. 1 fuel oil is recommended if the tank is outside and above ground. 2. The oil burner was started and tested at the factory. Double check to make sure the proper oil burner nozzle is installed and electrodes are set according to the oil burner manual. 3.
Operating Instructions Gas Firing the Unit To Start the Gas burner on new installation 1. With gas line in “off” position, install burner using gasket and tighten down with 3 nuts to furnace. 2. Connect 110 Volt power to burner 3. Connect 24 Volt power to the burner from the DS-103 Versatrol. 4. Set room thermostat 10 degrees above room temperature. 5. Allow burner to operate for 2 minutes until all air is purged from gas line. 6.
Operating Instructions BEST WOOD TO BURN All solid fuel, whether it is coal, pine, oak or any grain has about 12,000 BTU's per pound if its moisture content is zero. Wood that has been cut, split and air dried for 2 years has about 8,000 usable BTU's per pound. Hardwood such as oak or hard maple has nearly twice the BTU's per cord as pine or aspen because it is nearly twice as heavy. Freshly cut wood has about 50% moisture content. Wood that has been cut and split for 2 years has about 20%.
Operating Instructions STARTING WOOD FIRE WITH GAS OR OIL BURNER Place three or four 6 to 8 inch diameter logs in the firebox. Set the temperature on the small thermostat to the desired setting. Set the temperature on the larger thermostat above room temperature. The flame from the burner need not touch the wood to ignite. HAND FIRING WOOD Set the small thermostat above room temperature. Set the larger thermostat below room temperature. The damper to the firebox should now be open.
Operating Instructions WHAT SIZE COAL SHOULD I BURN? The air space between the furnace grates is 1/2 inch. Therefore, coal smaller than 1/2 inch can fall through the grates into the ash pan. • Pea size coal ranges from 9/16 to 11/16 inch. • Nut size coal ranges from 1-3/16 to 1-5/8 inches. • Stove size coal ranges from 1-5/8 to 2-7/16 inches. Nut size is preferred by most people and is recommended for use in this furnace. Anthracite coal is hard and burns like charcoal that is used in your barbecue grill.
Operating Instructions OPERATING INSTRUCTIONS FOR BURNING COAL ON 1/2-INCH OPENING GRATES (Optional) The following instructions are for burning various types of coal, storage of coal, and the cleaning of the furnace. Some coal is oil-treated at the mine. Some users have indicated that it tends to make the coal difficult to start. Burning coal requires some patience and a regular procedure. With improper tending, a coal fire can go out in a short time.

Maintenance GRATE CARE - ASH REMOVAL It is necessary that ashes be removed from the ash pan on a daily basis. The ashes should never be allowed to accumulate high enough to come in contact with the grates. Such a condition could cut off necessary air circulation. It could also result in a warping or burnout of grates. ASH DISPOSAL Unlike wood ashes, coal ash should not be spread on the garden. The minerals in coal ash contains several chemicals which could be harmful to plant life.
Maintenance SMOKE PIPE, CHIMNEY AND SECONDARY HEAT EXCHANGER Do not burn green or freshly felled wood. This may cause creosote and soot to build up in chimney, smoke pipe, and secondary heat exchanger. These should be checked and cleaned several times each heating season. CLEANING FURNACE AND CHIMNEY FLUE PIPES Frequently check and clean the furnace flue pipes and chimney. Soot and fly ash should not be allowed to build up on any of these surfaces. Chimneys are best cleaned professionally.
Maintenance FURNACE BLOWER ADJUSTMENT Set adjustable motor pulley so blower will give approximately 80-90º F temperature rise through furnace. After pulley has been adjusted check bolt as follows: The belt is drawn tight during shipment. Therefore both belt tension and sheave alignment must be rechecked by the installer. This is done when the furnace is placed in service. FIG. 36 Improper belt tension and pulley misalignment are the major causes of furnace fan noise.
Maintenance DUCT WORK AND BLOWER SPEED ADJUSTMENT Supply and return duct system should be sized properly for efficient operation. Normal air temperature rise through the furnace should be adjusted to approximately 80-90º F. Proper blower speed adjustment, in conjunction with adequate duct work are necessary to achieve this. A high temperature rise will result in excessive fuel usage. This is due to the high stack temperature that always accompanies a high air temperature rise.
Maintenance TESTING INSTALLATIONS FOR EFFICIENCY A Draft gauge must be used. Draft in smoke pipe must be set at -.03 Water Column updraft. Failure to set properly will cause fuel to be wasted, heating will not be satisfactory, fast buildup of creosote in heat exchanger and chimney may occur and cause damage to your heating system.
Maintenance TEST PROCEDURE Step 1. Set the thermostat high enough so that the unit will run for at least 15 minutes, the maximum time that should be required for the test. Let the unit operate enough for the stack temperature to stabilize. Step 2. For your initial set of readings, set the Draft Regulator so that there is -.03 Water Column Draft in the smoke pipe between the flue outlet and draft regulator. A manometer must be used to properly set the draft to -.03” WC. Step 3.
Maintenance FIREBRICK PLACEMENT Models (LWO-112 & LWG-112 ONLY) (Fig. 42) Model LWO-112 & LWG-112 (Left Hand Model Shown) Lower Row 1. Place 3 ea. 12”x 6” bricks at rear of firebox 2. Place 4 ea. 12”x 6” bricks on side opposite burner. 3. Place 4 ea. 9” x 6” bricks on burner side. Upper Row 1. Place 2 ea. 9” x 6” bricks at rear of firebox. The 9- inch side lying down. 2. Place 1 ea. 9” x 6” and 1 ea. 12”x6” bricks on side opposite burner. The 9-inch and 12-inch side lying down. 3.
Maintenance OIL BURNER MAINTENANCE MAINTENANCE AT THE END OF THE HEATING SEASON: 1. Shut off electric current to burner at fuse panel. 2. If oil filter has not been cleaned recently, it should be removed and cleaned. (Consult instruction card furnished with fuel unit). 3. Oil storage tank should be kept filled to prevent water vapor from collecting. It is suggested the valve in the suction line be closed. Oil storage tank should be cleaned every 2 or 3 years.
Maintenance Maintenance HOW TO PREVENT RUST AND CORROSION At the end of each heating season, clean both primary and secondary heat exchangers. Also, clean the ash pan thoroughly. Paint the inside of the heat exchanger with automobile crankcase oil. This will decrease rusting caused by summer moisture. The black paint on firing door area may wear or burn off. It can be repainted with a high temperature, flat black, air-drying paint. CLEANING THE CHIMNEY, SMOKE PIPE AND HEAT EXCHANGER Avoid chimney fires.
Maintenance TOP OF CHIMNEY LOWER THAN SURROUNDING OBJECTS REMEDY: EXTEND CHIMNEY ABOVE ALL OBJECTS WITHIN 30 FEET. SMOKE IN THE FURNACE ROOM This condition is usually caused because smoke is not being drawn up through the chimney. Other causes could be a failed (firebox)heat exchanger. Check with your qualified furnace service provider. CHIMNEY CAP PUSHED OVER FLUE OR FLU OBSTRUCTED BY A VENTILATOR REMEDY: REMOVE OBSTRUCTION Chimney causes: ACCUMULATION OF SOOT OR DEBRIS IN OFFSET REMEDY: REMOVE 1.
Maintenance OVER HEATING WHEN BURNING SOLID FUEL AS YOUR PRIMARY SOURCE OF HEAT If your home is overheating, your furnace is providing heat when the thermostat is satisfied. One of these ideas will help with overheating. 1. The best answer is to use fewer logs at each filling. This provides the maximum amount of heat while conserving wood. 2. There are 3 pegs in the fan and limit control. One peg is set at 250º F. Never change this setting. The middle peg is set at 150º F.
