LVWO Waste Oil Boiler - Columbia Heating

7) If permanent masonry chimney is not available, use appropriate diameter multi-wallmanufactured chimney and collars listed for use with oil fired boilers per UL 103 or AllFuel Class A. Locate for easy connection to the boiler and install per manufacturers'instructions and local building and fire codes. Proper burner settings and normaloperation will produce a gross chimney temperature between 400°F and 600°F.8) The chimney must extend a minimum of 3' above the highest roof line within 10'.In general you will need a minimum of 2 feet of vertical for each foot of horizontalfor best draft.9) Use a stack that is equal diameter to the boiler outlet (5 in.). Use minimum 24 gaugesingle wall connector pipe between boiler outlet and damper. Do not allow rain to comedown the chimney and have a path into fire chamber. This will create an environment thatwill promote rust. Install a chimney tee near the boiler to act as a cleanout / water trap.10) Locate barometric damper (draft regulator) near the boiler. Its opening must bevisible from the floor and out of strong airflows that could falsely affect its ability toregulate.10) Adequate air must be provided for combustion and ventilation. In buildings of tightconstruction, you should provide an opening connected to a well ventilated space, or theoutdoors. The opening should have a free area of 1 square inch per 1,000 Btu per hourfor all appliances located in the space. Boilers installed in confined spaces should havetwo ventilation openings each with a free area of 1 square inch per 1,000 Btu per hour forall confined appliances. One opening should be near the top of the space and the othernear the bottom.
