1. Whenever a loading door is opened it always should be cracked slightly to allow oxygen to enter and burn any combustion gases that are pres ent before fully opening Failure to do this could result in sudden igni tion of the unburned gases when the door is opened A stove never should be filled with excess coal so that the flue gas exit is blocked or impeded in any way Burning coal generates carbon monoxide If the flue gas exit is blocked the carbon monoxide can be forced out of the stove into the room with possible fatal consequences WITH THE EXCEPTION OF THE START UP PERIOD AN ASH PIT DOOR SHOULD NEVER BE LEFT OPEN Serious damage to the stove can occur from overheating Coal stoves should not be installed in any chimney that has had a his tory of back drafting or flow rever sal These conditions can cause improper draft resulting in carbon monoxide entering the house rather than being drawn up the chimney REMEMBER COAL GASES ARE TOXIC Sulfur dioxide sulfur trioxide and other ions released from coal burn ing may corrode stainless and masonry chimneys and even terra cotta chimney liners and brick in nearby buildings Coal with high sul fur content will destroy chimneys especially fast if soot sits in the flue for extended lengths of time It is important to clean chimneys regu larly 13 Optional Hot Water Coil 12 Warranty 12 1 Terms and Warranty Harman Stoves are warranted for five2. tion or in the parallel configuration with another furnace the following steps will apply in your decision as to where and how you will install your new solid fuel stove Clearance to Combustibles Models SF 150 SF 250 Safe stove clearance to combustible walls is 24 to rear and 36 to sides and front Floor protection for a combustible floor should consist of 3 8 asbestos millboard or a stove mat providing equal protection The floor protector should extend 8 to either side and 16 in front of the stove Floor protection should also extend 2 to either side of chimney connector Leveling Adjustable Feet A Lean the stove back and screw on the two front feet B Lean the stove front and screw on the two rear feet C Make final adjustments to bring the stove into a level position by adjusting feet as required Most Harman stoves are equipped with adjustable feet which are adjusted simply by turning them They are 4 in diameter to support the stove without marring the floor The shape of the foot adds to the appearance and quality of the stove IMPORTANT THE FLUE PIPE MUST BE 24 GAUGE OR THICK ER When connecting the flue pipe to the stove the first section of the pipe 36 or the elbow should be installed inside the flue connector on the stove It should be held in place by drilling three holes through the pipe The holes should be of suit able diameter for the sheet m

11. OW THE STOVE IS USED The chimney connector and chim ney should be inspected at least twice monthly during the heating season to determine if a creosote build up has occurred If creosote has accumulated it should be removed to reduce the risk of a chimney fire If an over fire situation should occur be sure ash door and fire door are closed In the event of a soot fire call your fire department immediately and make sure the ash door fire door and drafts are closed 6 Electrical 6 1 Warnings Turn off electric power at fuse box or circuit breaker panel before mak ing any line voltage connections Follow local electrical codes Be sure to route power so that it does n t come in contact with the stove IMPORTANT ALL WIRING SHOULD BE DONE IN ACCOR DANCE WITH LOCAL AND STATE CODES 7 Fuel 7 1 Firewood and Coal Fuel Information Sheet The energy content of most hard woods and all but a few softwoods is generally estimated to be around 8 6000 BTU s per pound at zero percent moisture content This however would not be a practical value to use in the calculation of fuel needed to meet a given heat load All the BTU s available in wood are not generated as usable sensible heat Much of this heat is dependent on the appliance s efficiency and is required in the venting system to generate a draft Also firewood is not available at zero percent mois ture Well seasoned sheltered wood contain
