CHIMNEY AUTOMATION SYSTEM (CASV)
Ensure boilers operate at maximum efficiency by providing constant draft at all firing rates. System senses draft and modulates fan speed as stack conditions or firing rate change to maintain desired draft setting. System solves difficult venting arrangements, allows different category appliances to be connected to a common stack and often reduces vent size and stack height. Vent sizing is determined and guaranteed by the manufacturer.
Features: Maintains perfect draft under all conditions. Eliminates common code violations. Reduced stack costs by allowing for a smaller stack size. Improve boiler efficiency and operation.

CHIMNEY FAN
Mechanical draft fan for installation at the chimney termination point, vertically or for side-wall venting. Assures a negative pressure in the entire chimney or stack system. Discharges horizontally (vertically, if side-wall vented) at a high velocity. Cast aluminum design.
Features: Variable speed, smaller stack sizes, solves code issues, high efficiency.

MODULATING COMBUSTION AIR SYSTEM (MCAS)
Provides make-up combustion air to boiler room exactly matching burner requirements. System senses room air pressure and modulates variable speed fan to match combustion air to burner firing rate by maintaining a constant room pressure. Replaces large combustion air louvers that often introduce excess cold air into the boiler room.
Features: Lower installation costs, smaller wall penetration, matches exact combustion air requirement.
