Imperial Mfg Group Usa Inc BM0052-A Cast Iron Damper

Product Description

The IMPERIAL MFG GROUP USA INC BM0052-A is a 7-inch cast iron vent damper designed to regulate airflow in residential and light commercial venting applications. Cast iron construction provides durability and resistance to high-temperature flue gases, making it well suited for use in gas, oil, or solid-fuel appliance venting systems. This damper is typically installed by HVAC technicians or plumbers during new installations or service calls where airflow control within a vent or flue is required.

The BM0052-A is used in round duct or flue vent applications with a 7-inch diameter opening. It is appropriate for residential furnaces, water heaters, boilers, and similar appliances that exhaust through a B-vent or single-wall metal vent connector. This part suits scenarios where a manual or gravity-operated damper blade is needed to limit backdraft or control draft when the appliance is not in operation.

Key Features

• 7-inch diameter fits standard round vent and flue connector openings
• Cast iron construction withstands elevated flue gas temperatures
• Damper blade controls draft and reduces heat loss when appliance is off
• Sold individually; packaged 12 units per case

Compatibility

Designed as an OEM-style replacement or new-installation damper for 7-inch round vent connectors in residential and light commercial heating appliances.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber in accordance with local mechanical codes and IFGC requirements. Shut off and lock out the appliance and allow the venting system to cool fully before handling any flue components. The damper should be oriented so the blade pivots freely and the shaft is accessible for inspection. Do not install in an orientation that restricts blade movement or traps condensate.
