LVWO Waste Oil Boiler - Columbia Heating

INSTALLATION OF CHIMNEY SYSTEMINSTALL CHIMNEY TO FLUE COLLAR OF BOILERFor best operation minimize distance of horizontal chimney runs. Do not exceed 8' in length.Horizontal runs must have a 1/4" rise per foot. Clean horizontal runs every 500 hours ofuse or as needed. Ash will accumulate here and block draft. Poor draft causes poorflame, backpressure, oily buildup, and unreliable ignition.WASTE OIL BOILERS ARE DEPENDENT ON PROPER DRAFT FOR EFFICIENTBURNING. ASSURE THAT ADEQUATE MAKE-UP AIR IS AVAILABLE. NEGATIVEDRAFT REQUIREMENT: -.04 to -.06 IN. OF WATER COLUMN BETWEEN THE BOILEROUTLET AND THE DRAFT REGULATOR AND APPROX -.02 OVER THE FIRE.BUILDING EXHAUST FANS OR COLD BUILDING TEMPS. AT NIGHT CAN REVERSEYOUR DRAFT AND CAUSE FUMES, POOR COMBUSTION, OR BURNER LOCKOUTS.TAKE MEASURES TO ASSURE BOILER WILL HAVE PROPER DRAFT DIRECTIONWHEN OPERATING. A DRAFT REGULATOR IS REQUIRED. A DRAFT INDUCER ISRECOMMENDED WHEN THERE IS INSUFFICIENT DRAFT.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 All FuelClass A. Locate for easy connection to the boiler and install per manufacturers' instructionsand local building and fire codes. Proper burner settings and normal operation will producea gross chimney temperature between 400°F and 600°F with a clean boiler.The chimney must extend a minimum of 3' above the highest roof line within 10'. Ingeneral you will need a minimum of 2 feet of vertical for each foot of horizontal flue forbest draft.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.If necessary, a draft inducer should be used to provide adequate draft conditions and shouldbe placed as near the building flu exit as possible. Inducers will pull air better than push it.Smaller inducers will not be adequate in some chimney installations. A draft regulator mustbe used in conjunction with a draft inducer.• Confirm local building codes will allow inducers• Locate inducer as close to where chimney exits building as practical• Never allow rain or condensation to flow back into boiler• Place a screen (1/2” or 3/4” openings) over stack to keep animals out• Observe clearance to combustible materials10
