Overview of the WB90

The Peerless Series WB90 is an Energy Star efficient, oil-fired cast iron boiler with an efficiency rating of 90% AFUE. It is designed for both direct and natural draft chimney venting and has a two-stage flame-retention burner for increased efficiency to meet both high and low heat loads. Standard features include a boiler reset control with low water cut-off, self-diagnostic burner control with indicator light, a temperature pressure gauge, and a built-in air elimination baffle. A full plate swing out door allows quick and easy cleaning, and a terminal strip simplifies field wiring. The unit's insulated powder coated jacket reduces both operating noise levels and heat loss.
