All of the below are approximations and examples only. All equipment can differ output by load and system matching. All the attached is meant to show common
examples for safe operation of Lennox equipment. CFM valves are not all exact available targets but will yield a close approximation to all applications.
Example: ML180UH045V36A (If the target cfm is 407 then a blower running at 400 to 420 CFM would be close)
