1. If Kickspace heater does not turn on check below for possible solutions:
A. Verify the following:
a) Check to see if there is a call for heat
• Turn up thermostat, wait for water to come up to temperature and unit blower/motor should turn on.
b) Verify aquastat is clipped firmly to copper tube. Clip may become loose during shipping. Located under
electrical box cover.
c) Check for power switch to be in low or high position
• Switch in front of unit should be switched to the left or right, middle position is off.
d) Check for power to the unit (115v) with voltmeter
e) Check supply piping to see if its hot
• If piping isn’t hot, water is not getting into the kickspace heater check the directional flow tee and
piping installation (see pages 4 and 5 for help with tee installation).
2. If above criteria have been verified and unit will still not turn on try the following:
Jumper out (by-pass) the aquastat; this should be done by a licensed electrician.
A. If blower turns on check below for possible solutions:
a) Water is not hot enough
• Check system water temp. If radiant system, low temperature aquastat may be needed.
b) Water not circulating fast enough
• Kickspace heaters must have at least 1GPM flow to operate properly. If system circulator is not
running kickspace heater will not turn on.
c) Water not getting into kickspace heater (supply line not hot)
• need to check installation piping and directional flow tee arrangement (see pages 4 and 5)
• Possible air problem – bleed air from unit
d) Thermostat wired to unit not working properly
e) Aquastat is not functioning properly
• Replace aquastat
B. If blower does not turn on:
a) Check all electrical connections
b) Blower motor may be defective
After going through these steps, if the unit still fails to operate, contact your local heating & plumbing contractor.
3. Noisy blower motor:
• Blower may have shifted during shipping/installation. A screwdriver may be used to push the blower
away from the motor. Simply insert a screwdriver between blower (end closest to electrical box) and
blower housing, and gently push blower away from housing.
