Fireplace Stand
Do not build a hearth more
than 1" above the baseplate
(this area must remain clear
for the access door).
If installed near carpet or other
combustible flooring, the fireplace
must be raised so the base of the
unit is above the carpet surface or
flooring material.
WARNING:
A non-combustible hearth is not required. However, if
the heater is installed next to the floor, we recommend
a hearth to protect the flooring surface from
discoloration or other negative impact from the heater.
A hearth is not required
when the fireplace is
raised above the flooring
surface.
