Boiler, Hot Water Supply. - Answer- A low-pressure hot water boiler having a volume exceeding 120 gallons (454 L), or a heat input exceeding 200,000 Btu per hour (58.6 kw) or an operating temperature exceeding 200°F (93°C) that provides hot water to be used externally to itself. Boiler, Low Pressure - Answer- A boiler for generating steam at pressures not in excess of 15 psig (103 kPa) or for furnishing water at a temperature not in excess of 250°F (121°C) at pressures not in excess of 160 psig (1103 kPa). Burner, Automatically Ignited - Answer- A burner equipped so that main burner fuel may be turned on and ignited automatically Burner, Manually Ignited. - Answer- . A burner equipped so that main burner fuel is turned on only by hand and ignited under supervision. Burner, Mechanical Draft Type. - Answer- A burner that includes a power-driven fan, blower, or other mechanism as the primary means for supplying the air for combustion. Burner, Natural Draft Type. - Answer- A burner that depends primarily upon the natural draft created in the chimney or venting system to induce the air required for combustion into the burner. Central Heating Appliance. - Answer- stationary heating appliance comprising the following classifications: boilers, central furnaces, floor furnaces, and wall furnaces. A floor-mounted unit heater to be connected to a duct system is classified also as a central heating appliance Centralized Oil Distribution System. - Answer- A system of piping through which oil is supplied from a separate central supply tank or tanks to more than one building, mobile home, recreational vehicle, or other structure. Certificate of Completion - Answer- A standard form issued for use in all jurisdictions throughout the Commonwealth. Chimney Connector.. - Answer- . The pipe that connects a fuel-burning appliance to a chimney. Clearance.. - Answer- The distance between a heat-producing appliance, chimney, chimney connector, vent, vent connector, or plenum, and other surfaces. Combustible Material. - Answer- Material made of or surfaced with wood, compressed paper, plant fibers, plastics, or other material that will ignite and burn, whether flame-proofed or not, or whether plastered or unplastered. Confined Space. - Answer- Confined Space. Any space whose volume is less than 50 cubic feet per 1,000 Btu/hr (4.8m 3 per kw) of the aggregate input rating of all fuel-burning appliances installed therein. Constant-Level Valve. - Answer- A device for maintaining within a reservoir a constant level of oil fuel for delivery to an oil burner. Control, Limit. - Answer- An automatic safety control responsive to changes in fluid flow or level, pressure, or temperature, and which is normally set beyond the operating range for limiting the operation of the controlled equipment by shutting off the energy supply. Control, Primary Safety (Combustion Safeguard) - Answer- A safety control responsive directly to flame properties, sensing the presence or absence of flame and, in the event of ignition failure or unintentional flame extinguishment, causing safety shutdown Control, Safety. - Answer- Control, Safety. Automatic controls (including relays, switches, and other auxiliary equipment used in conjunction therewith to form a safety-control system) that are intended to prevent unsafe operation of the controlled equipment.
