  • The RSHG was developed specifically for gas fireplaces and individual gas-fired boilers.

    The chimney fan has a horizontal discharge and an integrated monitoring system, consisting of a pressure control switch and a flow control.

    The RSHG is installed on top of the chimney and provides a controlled vacuum regardless of location, size or height of the chimney. The chimney fan can be used for both new and existing installations. The RSHG is part of an exodraft system and must be connected to an exodraft EFC21 or EFC25 control.

    The RSHG is made of corrosion-resistant cast aluminium and is designed for operation in hot and corrosive environments.

    The chimney fan withstands flue gas temperatures up to 200 °C and is delivered with a centrifugal impeller that ensures high efficiency. The wheel is driven by an enclosed heat-resistant asynchronous motor with permanently lubricated ball bearings that are developed especially for use in high temperatures. The motor is placed so that it is protected from flue gas and a special cooling plate ensures that the motor is continuously kept cool. The cable is heat resistant and strain relieved and protected by a reinforced hose casing.

    All of these combined give the chimney fan high operational reliability and a long service life.


    Integrated Security
    The built-in chimney fan pressure control switch is connected to the associated exodraft control that monitors the fail-safe function.

    The fail-safe function monitors whether the chimney draft is sufficient. If this is not the case, the gas supply is shut off and a gas leak is prevented.

    The chimney fan can be opened so that it is easily accessible for maintenance and repair work and a stainless safety mesh is mounted to protect fingers and birds.
