HEARTH REQUIREMENTS
Unless your heater will be standing on an un-covered fireproof floor which extends at
least as far as the minimum hearth areas shown below, it will be necessary to provide a
hearth for floor protection. See page 8 for construction details.
Having decided exactly where your heater will be installed, you will be able to establish
the size of hearth you will need. Where the minimum requirements bring the edge of
the hearth nearly to a wall, it is better to extend the hearth to meet the wall. In fact it is
sensible to increase all dimensions by moving up to the next available standard hearth
size so that precise positioning of the heater on the hearth will not be needed.

Note.
The hearth protecting a heat sensitive floor must extend behind the heater by at
least the following distances (measured from the rear heat shield):-
Arcadia
Utopia
Australia
200mm
100mm
New Zealand
325mm
(or to the wall if closer)
100mm
Usually a neater installation will result if the hearth extends right up to the rear
wall, but take care not to obstruct air flow into the lower ventilating slot of any wall
shields that may be fitted.
