Operating Instructions SF 2600 Oil Operation as Backup The SF 2600 offers a unique option to the homeowner The ability to have an efficient oil backup heat source built right into a wood coal furnace The operation of the oil burner as a backup system is as simple as setting a thermostat To use the oil portion of your furnace as a backup proceed as follows 1 Set the wood coal thermostat to the comfort level you desire 2 Set the oil thermostat to a level 5 to 10 degrees but not less than 3 degrees lower than the wood coal thermostat That s all there is to it The idea is that when the wood coal portion can no longer maintain the level set on that thermostat the oil portion will come on and maintain the temperature set on the oil thermostat SF 2600 Oil Operation Only In the oil only mode simply turn the wood coal thermostat to its lowest setting and select the comfort level you desire on the oil thermostat The SF 2600 will now act as a standard oil burner and maintain your chosen temperature NOTE It is recommended that the wood coal fire in the lower portion of the furnace be out or nearly out before going to oil only operation Curing Paint During the first few hours of burning a blue smoke will be observed rising from the painted sur face of the furnace It is advisable to increase the amount of fresh air in the room during this breaking in period This may be achieved by opening doors windows et

Chimney may be blocked with creosote or bird nests etc Improper sized chimney or stovepipe Too many elbows Distance of more than eight feet between furnace and chimney Down Drafts Trees or other topographical barriers may impede the chimneys operation causing a down draft condition to exist This can also be caused by adjacent buildings or chimneys Creosote and Condensation If creosote or condensation runs out of the chimney or stovepipe check the following Chimney cap or lining may be defective Furnace may be too far from chimney not allowing the chimney to get warm Wood being burned may be green or wet Unit may be too large for home causing wood to be burned too slow Excessive Draft This can be controlled with a barometric draft control on the stovepipe 13 Maintenance Maintenance The spiral chamber is basically self cleaning Hovvever if there is a draft problem and you have been burning vvood for a long time vvith little heat demand the spiral chamber may need cleaning Soft coal will also require more frequent cleaning To clean remove stovepipe and scrape the creosote from the front and top of the chamber and remove The rear of the chamber will not accumulate creosote NOTE 118 to 114 of creosote in the spiral chamber is normal Creosote can be burned off by burning coal for a fevv days Firebricks may become cracked during the course of normal operation A cracked brick
