Inspect the heater and check that
the air inlets and outlets are not
blocked as this may cause over-
heating. Unplug the heater for 30
minutes and allow it to cool down.
Replug and operate, but monitor the
heater for signs of overheating. If the
problem persists, discontinue use of
the heater and contact customer
service.

Power cord
overheating
protection has
activated.
Check your heater cord and plug
connections. Faulty wall outlet
connections or loose plugs can
cause the outlet or plug to overheat.
Be sure the plug fits tight in the
outlet. Heaters draw more current
than small appliances, so overheat-
ing of the outlet may occur even if
it has not occurred with the use of
other appliances. During use check
frequently to determine if your plug,
outlet or faceplate is HOT! If so,
discontinue use of the heater and
have a qualified electrician check
and/or replace the faulty outlet(s).

the control panel is

An object is too close

obstructing the air
outlet.
Verify there is a 3 foot clear space in
front of the heater air outlet.
To disable the Proximity Sensor safety
function press and hold the
ECO MODE button for 10 seconds.
