Draft Options:

• Forced Air Draft: When your home cools, the wall thermostat will activate the 60CFM draft blower to push combustion air into the burn chamber of your ENERGY KING A40EK-D Wood/Coal Boiler. The wall thermostat deactivates the forced air draft blower once your home has reached the desired temperature.

Grates Options: All ENERGY KING Wood/Coal Boilers come standard with stationary cast iron grates. Optional cast iron shaker grates are available.

Optional Domestic Hot Water Coil is not available on the ENERGY KING A40EK-D Wood/Coal Boiler.
