Installation Instructions
Congratulations on purchasing a kickspace heater from
Dimplex North America. Your heater is manufactured using
the highest quality materials and workmanship and will
provide many years of trouble free service.
!
NOTE: It is extremely important to read all information
labels. Care must be taken to ensure that the heater is
rated the same voltage as the electrical supply wires.
Failure to do so could result in unsafe heater operation as
well as damage to the unit. If replacing an existing heater,
check the labels of the old heater to ensure the voltage of
the new heater is compatible.
!
NOTE: Care must be taken to prevent undue strain on all
wiring or heating element assembly, when removing and
re-assembling heating element assembly.
CAUTION: For eld rewiring to 120V all leads must be
secured under wire clamps.
!
NOTE: Air and grille temperatures conform to CSA & UL
regulations but may discolour certain materials, particularly those materials incorporating clear vinyl. Materials
should be checked prior to installation to determine if
discolouration or distortion would occur in the vicinity of
60°C (140° F)
