It is required that a clearance of 24” be allowed at sides where servicing will occur and 18” allowed at a side where passage is necessary to another side requiring servicing or cleaning. Clearance on remaining sides should be no less than 6”. See Page 4 for permissable minimum clearance for alcove installations. NOTE: Installations must conform with the requirements of local utilities and those of other local authorities having jurisdiction. CHIMNEY OR FLUE The masonry chimney or Type A flue to which the boiler is connected must have a cross-sectional area not less than that of the cross-sectional area of the draft hood. The chimney should extend at least two feet above the highest part of the roof so that wind from any direction will not strike the flue or vent from an angle above horizontal and not produce a positive static pressure. Chimney linings should be used when required by national, state or local building codes. Vitreous tile linings with joints which prevent retention of moisture and linings made of non-corrosive materials are advantageous. Advice regarding recommended practice and material for flue connections and chimney linings can usually be obtained from the local gas company and should be given careful consideration. In the event a Type B or Type C vent is used, the instructions relative to size and height contained in the Manual ASA Z21.30-1959, American Standard Installation of Gas Appliances and Gas Piping should be followed. The chimney should be examined before the gas boiler is installed to ascertain that it is properly constructed, clear, and will freely conduct the products of combustion to the outer air. Flue piping should not extend beyond the inside wall of the chimney. Do not place a damper or any other obstruction in the flue pipe. The flue pipe should slope up toward the chimney at least 1/4*' per foot and must be the same size as the outlet of the draft diverter. Where two or more appliances vent into a common flue, the area of the common flue should be at least equal to the area of the largest flue or vent connector plus 50% of the area of the additional flue or vent connector. QJI&O AIR SUPPLY FOR BOILER ROOM Provisions must be made to supply sufficient air to the boiler room at all times. In buildings of conventional frame, brick, or stone construction without enclosed utility rooms, basement storm windows, or tight stair doors, infiltration is normally adequate to provide air for combustion and draft-hood dilution. For installations in utility rooms without an outside wall, ventilation to the rooms should be provided by placing an opening at the top and bottom of the room allowing a minimum of 1 square inch of opening for each 1000 BTU per hour input with not less than a 100 square inch opening in each location. Where openings to interior spaces are impracticable, openings to the outside with a minimum free area of 1 square inch per 4000 BTU per hour of input rating should be provided. IMPORTANT PRECAUTIONS Proper installation and adjustment of burners and control equipment are important for the successful operation of the gas boiler. The operating instruction -plate furnished with the boiler is mounted on the inner jacket panel. Read the instructions very carefully before starting the gas boiler. BOILER FOUNDATION A level concrete or brick foundation is strongly recommended and should be from two to a maximum of six inches above floor level if head-room permits.
