to be heated) and duct the heated air to its output
location. Also, air outlet plates to allow you to
install ducting for one, two or three separate outlets
(e.g. you can use one fan to heat two different areas
by installing a dual air outlet plate).
5.3 What NOT to Do
• Don’t install more fans that require more heat than
the Heating and Distribution Module can produce.
Your system will not run effectively. (If you choose to
use a higher-draw fan motor (more than 5 amps),
install a relay to handle the extra load; see Figure 5-3:
Installing a Relay for Additional Fan Amperage.)
• Don’t mount the return air outlet too close to the
fan’s air intake source.
5.4 Mounting Locations
Carefully choose the mounting locations of your fans:
• Locate the fans to evenly heat the zone.
• Provision must be made to protect water lines from
freezing. ITR can suggest
optimal fan locations
if you provide a floor
plan of your coach
or yacht.
• Install fan at floor level or very near floor level, in order
to optimize circulation.
• Allow a minimum 16 square inch (100 cm sq.) opening in
the fan heaters’ mounting compartment to allow sufficient
intake of air.
ITR’s Spacesaver fan (pictured at left) has two stainless steel
mounting brackets welded to the side of the case. It is
designed to be mounted horizontally on a flat surface.
This fan can also be ordered with a right-hand or left-hand
hose configuration.
ITR’s standard cabin heater fan comes with loose stainless
steel brackets. The fan can be mounted on the floor or on
the wall, either flat or on its side.
