Planning
Framing
Top of
fi
nished hearth must be
fl
ush with bottom of heater to
accommodate most optional
mantels and trims.
However, the
1140 Four-Sided
trim extends 1-1/2” below the
bottom of the appliance
. See
installation instructions packed
with 1140 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.
Any shims used underneath
to raise the heater should be
setback 1/2” behind front face
of framing otherwise top face of
shims may be visible.
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 H5 is a very effective radiant heater. The hearth/floor in front of the heater can get very
hot (in excess of 200ºF). Locating the unit raised above the hearth/floor and using the barrier
screen will greatly reduce hearth temperatures. Any hearth 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 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.
