Furnace opening should be ½ " larger than dimension C or D to allow for fillets and draft on mounting plate. C dimension used for jacketed tiles only. ¼ " body air pressure tap on -2, -3, -4, -5, -6, and 6-B. 1⁄8 " body air pressure tap on -7-A, -7-B and 8-A "Flower Pot" type flange for -8-A. Note larger G dimension For 4422-8-A, air and gas connections cannot be piped on the same plane. Flower pot type air connection flange would interfere with the 2 ½ " gas line. Pilot, Flame Detector, and Observation Port positions are interchangeable as long as Pilot and Flame Detector are in adjacent holes. ¾ " pipe plug furnished for use if no Pilot.
