When to use: Packaged heating boilers that generate hot water or low-pressure steam for building space heating and for heating loops that serve coils, heat exchangers, and indirect equipment, in commercial, institutional, and industrial buildings, constructed and stamped to ASME BPVC Section IV. Covers gas-fired, oil-fired, dual-fuel, and electric boilers; condensing and non-condensing combustion; fire-tube, water-tube, sectional, and finned-tube heat exchangers; single and multiple-boiler plants; the pressure vessel with its trim, relief valve, low-water cutoffs, and limit controls; the burner, the fuel train downstream of the appliance shutoff valve, and burner management; combustion air, flue venting, breeching, and draft control at the boiler; flue gas condensate neutralization; the boiler control interface to the building automation system; factory testing, startup, and field testing; anchorage; warranty; and spare parts.
− Not intended for: Domestic hot water equipment, including hot water supply boilers and indirect water heaters serving potable water (see [[sync/water-heaters]]); power boilers operating above 15 psig steam or above 160 psig or 250°F hot water, which are constructed to ASME BPVC Section I; heat-recovery steam generators and waste-heat boilers; process steam generators serving manufacturing loads; hydronic distribution piping beyond the boiler isolation valves (see [[sync/hydronic-piping]]); steam and condensate distribution piping, traps, condensate receivers, and condensate pumps (see [[sync/steam-and-condensate-piping]]); system pumps not furnished with the boiler (see [[sync/hvac-pumps]]); expansion tanks and air separators (see [[sync/expansion-tanks-and-air-separators]]); overpressure protection of any loop that can be isolated from the boiler, together with balancing devices, strainers, and other in-line specialties (see [[sync/hydronic-specialties]]); the boiler water treatment program and feedwater pretreatment (see [[sync/hvac-water-treatment]]); fuel gas piping upstream of the boiler's shutoff valve and connector (see [[sync/fuel-gas-piping]] and [[sync/natural-gas-piping]]); fuel oil storage, transfer pumps, and supply and return piping (see [[sync/fuel-oil-systems]]); steam-to-water and water-to-water heat exchangers (see [[sync/heat-exchangers]]); field-applied insulation of breeching and connected piping (see [[sync/mechanical-insulation]]); the controllers, network, and programming of the building automation system (see [[sync/building-automation-system]]); and warm-air furnaces (see [[sync/furnaces]]).
