3.4 Floor Protector Requirements
Installation of the Rangitata ULEB into masonry chimney needs an insulating base and the insulting floor
protector (hearth). The floor protector must be at least 900mm wide. The floor protector must extend all the
way inside the masonry chimney to ensure that the bottom of the fire does not rest below the top surface of
the floor protector. An existing masonry chimney may already have a suitable non-combustible
base/hearth. Make sure that the hearth level is matched with the floor protector height.
The insulated floor protector can be constructed with the material like Eterpan LD, Promatect or similar with
a heat transition coefficient of 5 W/m
2
K and layer of tiles or slate. The thickness of the floor protector for
the Rangitata ULEB depends upon the fascia option chosen and the floor type. Fig 2, 2A, 3 & 3A gives the
required floor protector thickness and projection from the door glass depending upon the
type of floor
and
the
fascia with or without the ash lip
