Hearth Pad Requirement
A non-combustible hearth protector with a thermal insulation rating of R-1 is required when installing this fireplace directly on
the floor and must extend a minimum of 12" in front of this fireplace. To build an R-1 rated hearth protection pad, begin by
laying down a ½” thick layer of an R -1 rated Mineral board (see
3.2.6.3 Suitable Finishing Materials R-Ratings
) and then add a
1” thick top layer of noncombustible material such as stone, granite, marble or the like.
For every 1” the fireplace is raised off the floor, the depth of the required hearth protector may be reduced
by 2”. If fireplace is raised off t he floor 6" or more, no hearth protector is required for fire protection .
Caution: The fireplace creates localized heat and causes thermal expansion of adjacently installed flooring
and wall materials. Vinyl floors and floating Engineered wood floors may warp if installed in front of this
unit even when this fireplace is
raised 6” or more due to local heating up of the floor material s. Never use
vinyl or Engineered wood flooring in the hearth pad area in front of this fireplace u nless you plan to raise
this unit 12” or more above the floor level.
Caution: Modern carpets use polypropylene, nylon or polyester fibers in the upper visible layer. These fibers
when exposed to radiant heat can curl and stiffen. It is not possible to prev ent radiation effects to the
carpet fibers even when this unit is raised high. Avoid installing carpets in the hearth pad area in front of
this Fireplace unless this fireplace is raised at least 12 inches above the carpet level .
This fireplace may be installed in an elevated position by created an elevated deck and an appropriate framed enclosure. NOTE:
This fireplace may be elevated but MUST allow a minimum of 72
” distance between this fireplace’s floor level and the ceiling of
the room.
