The Series 63™ boiler from Peerless is a residential, gas-fired boiler for hot water or steam systems. Shipped as knockdown (factory assembled sections), the boiler comes in seven sizes ranging from three to six sections (steam boilers are also available as packaged units). The Series 63™ boiler is available for either natural or LP gas and has AFUE ratings of up to 82%. A single vent draft hood allows for natural draft (chimney) venting. The significant water content of the Series 63™ boiler makes it ideal for large volume hot water applications. Standard equipment on the Series 63™ boiler includes steel push nipples that provide a permanent, watertight seal between sections. A probe type low water cut-off is standard on steam boilers. All Series 63™ boilers include standard standing pilot ignition (spark ignition is available as an option), Honeywell operating controls, vent damper and a slide-in, pre-assembled burner tray. A deluxe, insulated, enameled steel jacket completely encloses gas valves and burners, and reduces boiler heat loss. The low profile design of the Series 63™ boiler works well for limited clearance installations.

1 Net I=B=R Ratings are based on DOE Heating Capacity less an allowance for normal piping and pickup as determined by the Testing and Rating Standard for Low Pressure Cast Iron Heating Boilers of the Hydronics Institute. Water ratings are based on a piping and pickup factor of 1.15. Steam ratings are based on a piping and pickup factor of 1.33. Consult PB Heat before selecting a boiler for gravity hot water installations or for installations having unusual piping and pickup requirements such as exposed piping, night set-back, etc. Ratings shown are for elevations up to 2,000 feet. For elevations above 2,000 feet, ratings should be reduced at the rate of 4% for each 1,000 feet above sea level.

2 Minimum Natural Gas Inlet Pressure exceptions: 63-04 STDG 5.3”; 63-06 STDG 5.5”; 63-06 SPRK 5.3”.

3 Heating Capacity and Annual Fuel Utilization Efficiency (AFUE) ratings are based on U.S. Government tests. Before purchasing this appliance, read important information about its estimated annual energy consumption or energy efficiency rating that is available from your retailer.
