Adequate combustion and ventilation air must be provided to assure proper combustion and prevent possibility of flue gas leakage and carbon monoxide emissions, causing severe personal injury or sizes must comply with state, provincial or local codes. In their absence, use the following when boiler is in a confined room: Provide two permanent openings in boiler room one within 12 inches of ceiling, one within 12 inches of floor.

7 Minimum dimension of each opening is 3 When all air is taken from within building, each opening should be at least one square inch/1,000 Btuh boiler input and freely connect with areas having adequate infiltration from When all air is taken from outdoors, each opening should connect directly or by ducts from outdoors or crawl or attic spaces that freely connect with outdoors and sized as listed below:a. through outside wall or vertical ducts - at least one square inch/4,000 Btuh boiler through horizontal ducts - at least one square inch/2,000 Btuh boiler where ducts are used, they should be same cross-sectional area as free area of openings they are connected compensate for louver, grille or screen blockage when calculating free air openings. Refer to their manufacturer s instructions for size. If unknown, use: wood louvers - 20-25% free air.

8 Metal louvers or grilles - 60-75% free air. screens - not less than inch louvers in open position, or interlock with equip-ment to prove open before boiler combustion and ventilation air enters through sidewall openings, ensure openings comply with Fig-ures 2 and 3. Installation Start-Up Maintenance Parts5 Part No. 550-141-935/1018 Set boiler in place2 For packaged boiler:1. Remove top jacket panels. Set aside until after boiler is piped. The boiler contains ceramic fiber and fiberglass materials. Use care when handling these materials per instructions on page 38 of this manual. Failure to comply could result in severe personal Remove lag screws (2 in front, 2 in rear) from shipping Remove boiler from skid. Cables are already attached to block assembly. See Table 2 for lifting weight. Using crane hook middle of each cable to eye of crane.

9 Using hoist hook middle of each cable to hoist. Raise boiler off skid. Use pipe rollers under skid angles to roll Place boiler in final position. Center boiler on foundation, if Level boiler. Shim under skid angles, if Cut off cables. Cables are not intended for long-term usage. Cables may corrode inside boiler, weakening their lifting strength. Failure to remove cables can result in severe personal injury, death or substantial property Proceed to Perform hydrostatic pressure test, page block assembly:1. Remove lag screws (2 in front, 2 in rear) from shipping Remove boiler from skid. Cables are already attached to block assembly. See Table 2 for lifting weight. Using crane attach free end of cables to eye of crane. Using hoist attach free end of cables to hoist. Raise boiler off skid.

10 Use pipe rollers under steel skid angles to roll Place boiler in final position. Center boiler on foundation, if Level boiler. Shim under skid angles, if Cut off cables. Cables are not intended for long-term usage. Cables may corrode inside boiler, weakening their lifting strength. Failure to remove cables can result in severe personal injury, death or substantial property Inspect block assembly for disjointed sections. Check gas-tight seal of flue collector hood and cleanout plates. Gas tight seal must be maintained to prevent possible flue gas leakage and carbon monoxide emissions, resulting in severe personal injury or Check inside section assembly for any light passing through unsealed Mark all unsealed At unsealed areas, check for: damaged gaskets. sealing rope not in place. loose bolts or Correct all conditions and repeat step b.
