An exodraft flange is placed underneath the chimney fan, producing a safe and stable transition between fan and chimney.

When pairing our chimney fan with original exodraft accessories, you take comfort in knowing that everything will operate as they should, and will for another 2 to 3 decades.
We provide the following chimney fan mounting accessories:
The frequency converters from exodraft are used in association with the controls of the EBC20 to regulate how fast the 3-phased chimney fans rotate:
The EFC21 controls are used in association with the gas solenoid valves of the exodraft, which allows the gas to be opened and closed based on the EFC21 control’s input.
Once the gas supply is opened by the valve and the proper flow in the chimney is determined, the combustion can start.
If the control senses a minimal flow amount, the valve will close. This will eliminate the risk of gas emission.
EBC20/22 control relay box.
When more than a couple of boilers are attached to a chimney, a relay box can be applied to as much as four boilers.
If you require more than a quartet of boilers, you can connect an extra pair of relay boxes. A total of eight boilers can be controlled for each EBC20/22.
