DRAFT CONTROLS
A Series: Single Acting Deluxe
Stainless Steel Control for Oil, Solid Fuel and Fan Assisted Gas Burners.
B Series: Double Acting
Standard Control for Gas Heating Appliances.
The Problem:
Heating appliances are designed to operate with a consistent draft. [. . . ] By diluting the chimney/vent draft with varying amounts of room air they maintain the draft at a heater's flue outlet within a consistent, safe and efficient range.
Tjernlund venting products offer reliable performance, ease of installation and care-free maintenance . . . at an affordable price.
