Diermayer Flue gas damper MOK250 with actuator

The motor-actuated flue damper is suitable for all oil- and gas-fired appliances with or without forced draught, for solid-fuel heating appliances with minimal opening, for negative pressure flue systems and atmospheric gas-fired appliances as floor-standing boilers and wall-mounted units. It can also be used in biomass boilers, tiled ovens, fireplaces or combustion air ducts for fireplaces.

It opens before the burner starts or optimises the combustion of the solid fuel in combination with the stove regulator. During the times when the combustion heating appliance is switched off, it seals off the flue path and prevents the heated room air from escaping via the chimney and cooling the appliance as it passes.
The motorised version can be controlled in different ways: manual control via a power switch, temperature-dependent control via a thermostat installed upstream or fully automatically via the stove regulator.
