WOOD SUPPLY Some important rules for preparing good firewood are: Cut, split and stack the wood in the early spring and let it stand in the sun and wind all summer. Whether you purchase your wood or cut it yourself, spring is the best time to buy or cut your wood to insure it is good and dry come winter. If you live in a damper climate, it will take longer for the wood to season. By far the most important characteristic of any firewood is its moisture content.
IMPORTANCE OF PROPER DRAFT Draft is the force which moves air from the appliance up through the chimney. The amount of draft in your chimney depends on the length of the chimney, local geography, nearby obstructions and other factors. Too much draft may cause excessive temperatures in the appliance. Inadequate draft may cause backpuffing into the room and ‘plugging’ of the chimney. Inadequate draft will cause the appliance to leak smoke into the room through appliance and chimney connector joints.
SMOKE CURTAIN Furnace Assembly Instructions Using two 1/4-20 x 1-1/4” Carriage bolts, the smoke curtain clips and two nuts, attach the smoke curtain in place above the Fuel Feed Door as shown below. After installation, the smoke curtain should swing freely back into the furnace.
Distribution Blower & ACC. All electrical connections should be done by a qualified electrician. 1. To replace the Honeywell Limit Control (A): Unplug from power supply The control may be removable thru the access panel on item “B”. However it may be easier to remove item “B” entirely for better access. Remove item “B” by means of the eight(8) screws. If silicone, use a utility knife to score the silicone along the edges of the part.
Testing And Operating Procedures GENERAL FURNACE OPERATION After installation of the furnace is complete, it is ready for operation. The Honeywell Limit Control, in conjunction with a wall thermostat, operates the distribution blower and the actuated draft on the front of the furnace. The limit control is located on the rear of the furnace in the upper right corner and is accessible by removing the two screws in the cover plate.
TESTING 1. Check the actuated draft by turning the room thermostat up high enough so that the motorized draft opens. Then lower the thermostat setting to ensure it closes off. 2. Use a sheet of newspaper to test your draft by placing it inside the furnace and lighting it. STARTING A WOOD FIRE DO NOT BURN: 9. Manure or animal remains; 1. Garbage; 10. Salt water drift wood or other previously salt water 2. Lawn clippings or yard waste; saturated materials; 3.
EFFICIENCY Efficiencies can be based on either the lower heating value (LHV) or the higher heating value (HHV) of the fuel. The lower heating value is when water leaves the combustion process as a vapor, in the case of wood stoves the moisture in the wood being burned leaves the stove as a vapor. The higher heating value is when water leaves the combustion process completely condensed.
CREOSOTE - FORMATION AND NEED FOR REMOVAL When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes an extremely hot fire. The chimney should be inspected at least twice monthly during the heating season to determine if a creosote build-up has occurred.
Domestic Hot Water Coil Kit - Optional This Furnace will accept the installation of a Domestic Hot Water Coil Kit. The U.S. Stove kit is a 1124 Water Coil and it may be purchased from your local dealer. 1. Remove the access panel on the rear of the furnace enclosure. 2. With a utility knife, cut away a section of the insulation directly behind the access panel. 3. Remove the cover plate from the rear of the furnace firebox. 4.
Trouble Shooting And Problem Solving Problem Solution 1. Smoke puffs from furnace • Check chimney draft. Check for blocked chimney or flue pipe. Use mirror to check chimney clearance. • Check ash pit — if it is too full, empty. • Make sure all of chimney mortar connections are airtight. • Check ash drawer. Make sure it’s airtight. • Check chimney for possible down-draft caused by taller surrounding trees or objects. Correct with proper chimney vent cap.
