On blower units L = C + P is distance from front of unit to back of blower enclosure and minimum of distance to wall.
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.
BSH 130 through BSH 225 – 4 holes. BSH 280 and BSH 340 – 6 holes.
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.

At 65°F ambient and unit fired at full rated input. Max mounting height as measured from bottom of unit, and without deflector hoods.
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.
Data listed is for standard 115-volt, 60-Hertz, single-phase motors. All single phase motors are totally enclosed and thermal overload protected.
