1.1. Technical data
Technical data according to AS/NZS 4012 & 4013
Max average heat output: 11.4 kW
Overall average efficiency: 65%
Efficiency on Low setting: 73%
Particulate emissions: 1.4 g/kg
Operational mode: Intermittent
Intermittent combustion is here taken to mean normal use of
a fireplace. I.e. that a new flame chamber is lit as soon as the
fuel has burnt down to the appropriate quantity of embers.
1.2. Floor Protector
Unless the heater will be standing on a heat resistant floor
such as a concrete slab with slate or tiles, it will be necessary
to provide a floor protector (hearth) to install on.
The floor protector must extend at least from the back of the
heater, up to a specified distance in front of the door opening.
The table and drawing below show the MINIMUM dimensions
(mm) required for the floor protector. It may be desirable, for
example aesthetic reasons, for the floor protector to be larger
than these minimum dimensions.
The floor protector must not be less than 5mm thick with a
thermal conductivity not greater than 0.33 W/m°K, or an
equivalent.

1.3. Positioning the heater
First, review the necessary clearances to combustible surfaces
(mm) specified in the table and drawings below before
considering where to position the heater. The clearances are
only valid if one of the flue shield options are used from
section ‘Installing the Flue’.
Check the practicability of installing the flue system in relation
to any obstructing roof beams before positioning the heater.
If the heater is being installed adjacent to a non-combustible
wall, then the installation must be in accordance with AS/NZS
2918.
