➀ On blower units L = C + P is distance from front of unit to back of blower enclosure and minimum of distance to wall.
➁ Dimension from rear of unit burner box to center line of gas pipe connection is 6-23/32" for BSH 130 and 6-1/2" for all other models.
➂ BSH 130 through BSH 225 – 4 holes. BSH 280 and BSH 340 – 6 holes.
➃ Distance between mounting hole in unit casing and mounting hole on blower, except on 280 and 340, then distance from rear mounting hole in casing.
➄ Motor pulley is adjustable.
➅ At 65°F ambient and unit fired at full rated input. Max mounting height as measured from bottom of unit, and without deflector hoods.
➆ Note: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. (In Canada see Rating Plate.) Reduction of ratings requires use of high altitude kit.
➇ Data listed is for standard 115-volt, 60-Hertz, single-phase motors. All single phase motors are totally enclosed and thermal overload protected.
