➀
Diameter of round vent pipe to fit oval opening.
➁
BD 50 thru BD 300 — 4 holes (2 on blower and 2 on unit). BD 350 and BD 400 — 6 holes (2 on blower and 4 on unit). (Listed is the hole diameter and threads per inch to accept
threaded rod).
➂
This is an approximate dimension for standard motors, allow 3" for sheave and optional motors.
➃
Distance between mounting hole in unit casing and mounting hole on blower. On the BD 350 and BD 400, the distance is from rear mounting hole in casing to the mounting hole on blower.
➄
For natural gas; may vary depending on control availability.
