FLOOR PROTECTOR (Hearth) CONSTRUCTION
In Australia the minimum floor protection requirement is a sheet of 6mm fibre cement board. It is
usually fastened directly to the floor.
In New Zealand, some woodfires must have an insulating floor protector. (See page 6). All other
current models may be installed on an ash type floor protector. Of course, all models may be installed
on insulating floor protectors if desired. The necessary minimum construction details for ash and
insulating floor protectors are shown below, and such constructions are suitable for use on solid
timber or particle board floors. Bricks or concrete in contact with the flooring material do NOT
provide the required insulation. If the floor within 500mm of the appliance is concrete and has no
combustible material in contact with it, a floor protector is not required. In this case, if tiles or pieces
of slate etc. are required for decorative purposes, they may be fixed directly to the concrete floor.
In all cases, in both countries, the protector must extend right under the woodfire and a durable top
surface will be needed to resist damage from heat or dropped embers. Obvious surface materials are
slate, bricks and ceramic tiles. Any gaps in the top surfacing material must be grouted to prevent the
penetration of embers. A trim moulding will provide a neat edge finish.
INSTALLING THE FLUE
You MUST use a flue system which complies with the current Australian or New Zealand Standard
as appropriate. Always seal the flue to the flue socket of the firebox using firebox cement or fibreglass
rope.
In Australia, only flue systems tested with your particular model are approved for use. The flues and
flue heat shields tested in Australia are detailed under the table on page 5. Unless otherwise specified
on page 5, all heat sensitive wall material must be kept at least 600mm away from any flue which is
not fitted with a flue heat shield.
In New Zealand we recommend the use of genuine Masport flue kits. The flue MUST be installed in
accordance with the detailed instructions accompanying it. Grandview & Toronto ceiling plates must
be at least 450mm square. A flue heat shield, as detailed on page 4, may be fitted at the back of the
flue (directly above the stove) to achieve the reduced wall clearances shown in the table. The Masport
flue heat shield for 150mm flues is Part No 551481, while the shield for 178mm flues is Part No
551793.
FIXING THE WOODFIRE IN POSITION
Once the flue shielding system has been installed through the ceiling and roof, the woodfire can be
placed in its approximate position on the floor protector, and the flue pipes installed. Finally adjust the
stove position making sure the flue is vertical and that the necessary minimum woodfire-to-wall
distances are being achieved. In New Zealand and some parts of Australia, Standards require that the
woodfire and floor protector be secured to prevent shifting in the event of an earthquake. This is best
done by fastening the woodfire right through the protector to the floor, using two screws not less
than 12 gauge, or the equivalent size of coach bolts or toggle fasteners. Anchor the appliance through
the holes in the seismic restraint bracket at the rear of the pedestal or in the two angle brackets
supplied. The angle brackets attach at each side of the pedestal (except for the LE 2000, where they
attach at the rear). The pedestal can be fastened to the seismic restraint bracket either before or after
fitting the anchor screws. The small centreline hole in the bracket will help in pre-positioning it.
