Position the fire at the right height. Use the adjustable
feet to adjust the height of the appliance. Connect the fire
and finish the fireplace.
Mantel iron
An L-shaped mantel Iron can be ordered from your
installer.The mantel Iron, intended to support the
brickwork above the fire.This enables a stress-free
installation of the appliance. Fit the mantel iron as
illustrated in fig. 3, allowing 5 mm between the top of the
appliance and the bottom of the mantel iron, so that the
packing cord provided seals adequately. Make sure that
the front of the heater (without the decorative facing)
and the front of the mantel iron are flush. Fitting the
decorative facing will hide the mantel iron from sight.

Figures 1 and 2 also show the possibility of a convection-
heat connection.
The convection system of flexible pipes will enable the
heat to be spread to every corner of the room.The
connection materials can be ordered separately from
your dealer.
Possible connections (fig. 4)
