6.7.2 DIMENSIONAL CONSIDERATIONS FOR BYPASS DUCT

6.7.3 INTERLOCKING DAMPER POSITIONS TO THE PRIMARY AIR CONTROL OF
THE WOOD FURNACE
A circuit can be created that will prevent the wood furnace from going to high fi re if the seasonal dampers are
not in the winter heating position.
Start by mounting the mechanical limit switches in such a manner that the actuator handles of the seasonal
dampers come into contact with the actuator mechanism of the limit switch.
This action should cause the contacts of the switches to close when the dampers are fully in the winter heating
position.
By connecting the three mechanical limit switches in series with the low voltage control circuit (which contains
the air damper motor), the air damper will not open (required to bring furnace to high fi re operation) if any of
the three limit switches have not been closed.
The control circuit that requires the limit switches runs between terminals #10 and #11 of the control terminal
strip mounted on the wood furnace control box.
NOTE
Accessory Kit HMFK-AC1 contains mechanical limit switches and mounting brackets suitable for this circuit.
