Section 5, Installing Fan Heaters
5.3 What NOT to Do
•
Don’t install more than two (2) fans, or fan(s) that require
more heat than The WaterHeater™ by ITR can produce. Your
heating system will not run effectively. (If you choose to use
a higher-draw fan motor, 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:
ITR can suggest
optimal fan locations
if you provide a floor
plan of your coach.
•
Locate the fan to evenly heat the zone.
•
Provision must be made to protect water lines from freezing.
•
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.
The thermostat should not be mounted on walls outside of the zone
because that could cause false temperature readings. Mount on
interior walls and bulkheads, away from windows and heater vents.
