LVWO Waste Oil Boiler - Columbia Heating

SYSTEM INSTALLATION PROCEDURE1) Select a location for your boiler observing minimum clearance to combustibles. See“Boiler Room Requirements” in this manual. Consider that maintenance and cleaningwill be required. Allow adequate work space around burner and stack. Three feet ofclearance on around all surfaces is recommended.2) Mount boiler on a non-combustible level surface and observe minimum clearances tocombustibles. Elevating the boiler on non-combustible blocks will make maintenanceeasier. For clearances less than listed below, consult NFPA-31.Minimum Clearance to combustible MaterialsSides: 2”Rear: 2” (Allow clearance to remove rear door for cleaning, approx. 18 in.)Front: 12” (Allow clearance to open swing door for cleaning, approx. 22 in.)Chimney Connector: 6”3) See the piping layout diagram (Appendix A.) for suggested piping arrangement. Theboiler is equipped with a built in air scoop. This feature allows quiet air free operation ofyour hot water system by assuring removal of air pockets without the use of Air Scoopdevices. The 1 ¼” supply fitting on the top of the boiler extends approximately 1” belowthe top of the boiler, thus allowing only air-free water to enter the supply. An AutomaticFloat Vent, provided by others, must be installed on the ¾” vent tapping, as shown in thepiping diagram to vent trapped air.4) For best operation minimize distance of horizontal chimney runs. Do not exceed 8' inlength. Horizontal runs must have a 1/4" rise per foot. Clean horizontal runs every500 hours of use or as needed. Ash will accumulate here and block draft. Poor draftcauses poor flame, backpressure, oily buildup, unreliable ignition.5) 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 THEBOILER OUTLET AND THE DRAFT REGULATOR AND APPROX -.02 OVER THEFIRE. BUILDING EXHAUST FANS OR COLD BUILDING TEMPS. AT NIGHT CANREVERSE YOUR DRAFT AND CAUSE FUMES, POOR COMBUSTION, OR BURNERLOCKOUTS. TAKE MEASURES TO ASSURE BOILER WILL HAVE PROPER DRAFTDIRECTION WHEN OPERATING.6) CHECK DRAFT AFTER START-UP AND STEADY STATE. THEN CHECK BYOPENING DOORS AND STARTING VENT FANS TO ASSURE THAT DRAFTREGULATOR CAN MAINTAIN -.04 TO -.06 UNDER ALL CONDITIONS. A SECONDREGULATOR MAY BE NEEDED IF DRAFT CAN NOT BE MAINTAINED. A DRAFTREGULATOR IS REQUIRED ON ALL INSTALLATIONS. A DRAFT INDUCER ISRECOMMENDED WHEN THERE IS INSUFFICIENT DRAFT.4
