When designing the floor
heating system, care must be taken to
ensure that proper clearance is
maintained from electrical
fixtures, cabinetry, partition walls and
other permanent features.
Permanent Features -
RetroHeat heating panels
must be installed so that they will not
be covered, even in part,
by partition walls or other structures
that cross the floor. Heating panels
that are covered by any
structures may overheat.
Wiring - Electrical
wiring in the floor must be
at least 2 inches away from the heating
panels with a barrier of
insulation filling that space. This
space may be horizontal along
the joist space.
Surface Mounted
Fixtures - Do not install the
heating panels closer than 8 inches from
the edges of any
electrical boxes for surface mounted
fixtures in the floor since
surface mounted fixtures may have
additional trim which extend
far beyond the edges of the electrical
boxes.
Recessed Fixtures - At
least 2 inches of
clearance must be maintained between the
trim of recessed fixtures
or outlets and the heating panels.
Heat Sources - At least
8 inches of clearance must
be maintained between heat sources and
the heating panels.
Pipes - At least 2
inches of clearance must be
maintained between any pipes (metal or
plastic) and the heating
panels.
End of Joist Cavities -
Leave at least 6 inches of
clearance at each end of each joist
cavity to accommodate
wiring and assembly.
