Homeflame Dream firefront
If a reduced depth hearth is fitted, the fire must be installed so that the distance
from the base of the fireplace opening in the wall to the finished floor level is at
least 100 mm. It is recommended that the reduced hearth has a depth from the
fixing plane of the fire of 100mm minimum. This is necessary to support the
lower front casting. Where there is no floor covering or carpet and the floor is of
a type that is likely to be covered in such a way in the future then the distance
from the base of the fireplace opening in the wall to the floor level should be
increased to at least 175mm.
