The required combustion air and intake size for the Weil-McLain 486 Series boiler is as follows:
- Combustion air requirement: 1 cubic foot of free area per 1,000 BTU/hr input when drawing air from indoors. For outdoor air, each opening must be at least 1 square inch per 4,000 BTU/hr input if horizontal ducted, or 1 square inch per 2,000 BTU/hr input if vertical ducted. - Air intake size: The air intake pipe should match the boiler model and burner requirements. For example, a typical Weil-McLain 486 Series boiler may require a 10-inch or larger diameter intake depending on the burner and vent configuration.
Exact sizing depends on specific model configuration and burner type. Always refer to the boiler’s installation manual for precise requirements.
