OPERATION : OPERATIONAL SAFETY GUIDE
OPERATIONAL SAFETY GUIDE
DO NOT OVERFIRE . If steam discharges from the overflow pipe or manway cover – you are over firing. Higher temperatures significantly increase water loss and can exacerbate
corrosion.
DO NOT OPEN THE LOADING DOOR IF THE BLOWER STOPS OPERATING DURING A BURN. Opening the loading door allows smoke to enter the room. Ventilate the space
immediately if the smell of wood smoke is strong.
RISK OF FIRE OR EXPLOSION: DO NOT BURN GARBAGE, GASOLINE, OIL IN ANY FORM OR OTHER FLAMMABLE LIQUID. DO NOT BURN TRASH, PLASTICS, HOUSEHOLD GARBAGE, MATERIAL TREATED WITH PETROLEUM PRODUCTS (PRESSURE TREATED WOOD, RAILROAD TIES, PARTICLE BOARD,
ETC), LEAVES, PAPER PRODUCTS, CARDBOARD.
DO NOT USE LIGHTER FLUIDS, GASOLINE, NAPTHA, OIL, OR ANY OTHER LIQUID FUEL TO START A FIRE. DO NOT OPERATE with the fuel loading door open. DO NOT OPEN the fuel-
loading door if a flammable gas is present.
APPROVED FUELS Seasoned Cord Wood: Firewood that has been cut, split and dried for one year is best. Wood cut 24” to 32” long x 6” diameter is considered best. Longer lengths should be cut and larger diameter logs should be split. Load the woodpile toward the rear of the combustion chamber to allow airflow. Any type of stick wood; i.e. oak, birch, poplar, pine, etc. is very acceptable. Dry wood at 15 to 20% moisture content contains 6880 BTU’s per pound. Briquettes: Briquettes consist of wood scrap that has been highly densified (without adhesives) into small 3” diameter “logs” that are 3” to 8” long. Because of the high cost to set up a facility, briquettes are usually the by- product of a large wood products company (furniture, door and window trim, etc). They are usually sold in 70 lb paper bags, like dog food. Load the bag and contents into the combustion chamber, ignite the bag and shut the door. Clean Scrap Wood: This may be waste from construction sites, truss-manufacturing facilities, pallet recycling facilities, etc. This fuel is usually very dry and bark free. Cut it to 24” to 32” lengths and stack it neatly in the combustion chamber. Because scrap wood fuel has a high surface to volume ratio and is dry, puffing may occur. Stack the wood tight (to reduce exposed surface area) and use a primary air control brick (see page 108). DO NOT BURN PAINTED OR PRESSURE TREATED WOOD.
