Installing Fan Heaters – With
“Space Heating Module” Only
5.1 Before You Begin
ITR makes a variety of fan heaters that can be independently
controlled by a thermostat. There are cabin heaters and Spacesaver
heaters (where space is limited). These heaters draw as little as 0.9
amps and deliver 140 cfm. These heaters also come in high output
versions and the above numbers are increased by 40%. They
should be mounted as close to the floor as possible. They have a
built-in aquastat which turns on the fan when the water running
through it reaches 120°F (49°C).
The Defrost Heater provides up to 28,000 BTU/h and uses a three
speed fan, 200/275/450 cfm, 40/55/100 watts.
Note: A limited number of fan heaters can be used with The
WaterHeater™ by ITR.
Only the installation of ITR fan heaters is covered in this Manual.
If you are installing non-ITR fan heaters, you must obtain prior
approval from ITR. You must check the fans’ total amperage draw
to ensure they will be compatible with the Zone Control Board, as
well as flow capacity to ensure that each fan meets system
requirements.
