HeatMaster SS MF e Series

Features beyond the standard MF Series include:

Additional Heat Exchange Pass
All eSeries furnaces are built with an additional heat exchange pass. This unique design forces heat and smoke to travel the length of the furnace three times to allow for maximum heat transfer, slower heat escape and increased fuel efficiency.

Secondary Air Injection – Optional
A rear mounted blower fan injects air into the fire box via a primary and secondary air duct and damper system. The adjustable dampers allow for control of required air injected into the fire box according to fuel requirements.

Easy-Access Hinged Rear Door
The insulated rear door is built with a unique hinge design which allows for easy access to the rear of the furnace and quick and easy removal of the door if required without the use of tools or hardware.
