Top of
fi
nished hearth must be
fl
ush with bottom of heater to
accommodate most optional
mantels and trims.
However, the
1440 Four-Sided
trim extends 1-1/2” below the
bottom of the appliance
. See
installation instructions packed
with 1440 for more information.
NOTE:
Unit will need to be
raised above plywood sub-
fl
oor in most cases due to
combustible hearth/
fl
oor
restrictions.
Insulation board in
non-combustible hearth
When the appliance is installed directly on carpeting, tile
or other combustible material other than wood
fl
ooring,
the appliance shall be installed on a metal or wood panel
extending the full width and depth of the appliance.
Hearth
WARNING
The H6 is a very effective radiant heater. The hearth/floor/exposed surface in front of the
heater can get very hot (in excess of 200ºF). Locating the unit raised above the exposed
surface and using the screen front will greatly reduce this surface’s temperatures. Any
exposed surface within 4 inches of the base of the heater must be constructed of non-
combustible materials and utilise the insulation board supplied as a thermal break between
the non-combustible exposed surface/hearth finish and the combustible construction below
(see diagrams in the following pages). Note that some materials, although safe can degrade
due to heat—take this into consideration when choosing materials.
