BEFORE YOU START
First, check the load bearing capacity of your floor
Before installing the appliance, you must ensure that the load
bearing capacity of the floor is equal to the weight of the
appliance, as well as any flue pipes and connections. The weight
of the appliance is 75kg approximately when empty. Remember
to also account for the additional weight once the appliance
contains the internal components and fuel.
1.
Check clearance to combustibles
The minimum clearance to combustible materials is 500mm on
both sides of the appliance, 400mm to the rear of the appliance.
A minimum of 80mm clearance should be left at the back and
sides of the appliance to allow free air movement and for heat to
enter the room. There should be a minimum clearance around
the 5” flue pipe of 225mm radius above the appliance.

5.
Ensure the suitability of your hearth
The appliance should be installed on a minimum 12mm
thick, non-combustible hearth. The hearth should extend to
a minimum distance of 225mm in front of the appliance and
150mm to each side, measured from the door of the combustion
chamber. Please refer to
document J
of the building regulations
for further information on hearth requirements.
2.
Inspect your chimney
An existing chimney or a new flue installation should be given
a visual inspection to check that it is in good order, clear of
obstructions and is of a suitable size and type for the appliance.
It is essential to first sweep the flue before fitting the appliance
or lining a chimney.
4.
Inspect your airflow
In order for smoke to be drawn up the chimney, ventilation into
the room is required. Normally, sufficient air will come into a
room naturally, however in some modern passive homes, there
may be a need for additional ventilation. A chimney requires
air movement to work, which may not possible if there is an
inadequate source of air. Prior to installation, you should ensure
you have the correct conditions in order to operate this appliance.
