Indicates presence of hazards that will cause severe personal injury, death or substantial property damage if ignored. Indicates presence of hazards that can cause severe personal injury, death or substantial property damage if ignored. Indicates presence of hazards that will or can cause minor personal injury or property damage if ignored. Indicates special instructions on installation, operation, or maintenance that are important but not related to personal injury hazards. Symbol Definitions The following symbols are used to indicate sequence of installation for: Factory-assembled packaged boiler—block, jacket and controls. Sizes 3 through 6 only. Factory-assembled block, no burner. Sizes 3 through 6 with jacket installed; steam trim controls shipped separately. Sizes 7 through 9 with jacket and steam trim controls shipped separately. When Calling or Writing About the Boiler Please have boiler model number and series from boiler rating label and CP number(s) from boiler jacket, burner and controls. On page 26 of this manual is space to list CP number(s). Table of Contents Table of Contents Read all instructions before installing. Failure to follow all instructions in proper order can cause severe personal injury, death or substantial property damage.

Before selecting boiler location: • Check for nearby connections to: — System water piping. — Chimney. See pages 12-13. Boiler can be top or back vented. — Combustion and ventilation air supply. See page 5. — Oil supply. See page 24 for oil line routing. — Electrical power. • Check area around boiler. Remove any combustible materials, gasoline and other flammable liquids. Failure to keep boiler area clear and free of combustible materials, gasoline and other flammable liquids and vapors can result in severe personal injury, death or substantial property damage. Provide clearances around boiler (see FIGURE 1): Jacket cap must be in place on boiler to avoid requiring an 18" minimum clearance from back or top of boiler to combustible material. • Minimum clearances from vent pipe to combustible material: 6 inches — Type “L” doublewall vent* 18 inches — Singlewall vent* Flue pipe clearances must take precedence over jacket clearances. • Recommended service clearances: 24 inches — Front and top 6 inches — Left side**, back and right side . 15 inches — Left side with tankless heater** 12 inches — Right side for burner door swing radius . Recommended Service Clearances FIGURE 1 Before Installing Boiler CONTINUED Before Installing Boiler CONTINUED Provide air for combustion and ventilation: Adequate combustion and ventilation air: • Assures proper combustion. • Reduces risk of severe personal injury or death from possible flue gas leakage and carbon monoxide emissions. Do not install exhaust fan in boiler room. Older buildings with single-pane windows, minimal weather-stripping and no vapor barrier often provide enough natural infiltration and ventilation without dedicated openings. New construction or remodeled buildings are most often built tighter. Windows and doors are weather-stripped, vapor barriers are used and openings in walls are caulked. As a result, such tight construction is unlikely to allow proper natural air infiltration and ventilation. Follow state, provincial or local codes when sizin...
