OIL FIRED DIRECT VENT BOILERS
The cast iron swing door allows quick and easy inspection of the oil burner and combustion area. In addition, wider flueways allow easier installation and maintenance of the SW. The SW is designed with redundant seals - fiberglass rope and silicone form an air tight seal to prevent leaks. A manual safety disconnect prevents accidental burner firing when the swing door is open. Pressure switch insures adequate combustion air in all cases. Pre-purge establishes air flow before ignition. Post-purge expels exhaust from the combustion chamber and vent pipe. An oil line solenoid prevents afterburn from occurring. Optional tankless water heat coil on SW-4 model produces hot water for domestic use. Standard equipment includes cast iron boiler, flush jacket, swing-out burner door, clean cut AFG Beckett oil burnere, traget wall/liner, circulator, ASME relief valve, theraltimeter gauge, drain cock, wiring harness, high limit and circulator control, primary control/burner relay.
