‡ Increase dimension ½ " for minimum opening in furnace shell. § Ambient temperature jet air is required at all firing rates for burner stability and flame integrity. Companion flange by customer (ANSI). Use flat face companion flanges and full face gaskets when installing this equipment. Raised face flanges may damage mating flange.
Specify order of assembly by giving arrangement designators for the pilot boss and gas inlet, relative to the main air connection located at twelve o'clock. The pilot and main air cannot have the same position since the air flange would interfere with the pilot. Two ¾ " connections on either side of the pilot boss accommodate an observation port (included with burner) and a UV detector.
