Description
The Burnham Boiler 8116324 is a genuine OEM 7″ vent damper engineered to reduce standby heat loss and improve the overall efficiency of compatible Burnham boiler systems. By automatically sealing the flue passage the moment the burner shuts down, this damper prevents residual heat from escaping up the chimney during off-cycles — keeping energy where it belongs and reducing fuel consumption over time.
Key Features
- Genuine Burnham Boiler OEM replacement part — ensures proper fit and reliable performance
- 7″ diameter design for precise compatibility with qualifying Burnham boiler flue connections
- Automatically closes the flue opening when the burner is off, eliminating standby heat loss
- Helps lower fuel costs by retaining heat between firing cycles
- Designed for straightforward installation on compatible Burnham boiler models
Why a Vent Damper Matters
When a boiler burner cycles off, an open flue becomes a direct pathway for warm air — both from the boiler room and residual heat exchanger warmth — to escape up the chimney. A properly functioning vent damper closes that pathway immediately, preserving heat within the system and reducing the energy demand of the next firing cycle. The result is a more efficient, cost-effective boiler operation over the long term.
Application & Compatibility
This vent damper is intended for Burnham boiler systems requiring a 7″ flue connection. Always verify compatibility with your specific boiler model and serial number prior to installation. Consult the boiler’s installation and service manual or contact Burnham technical support to confirm fitment before ordering.
