REMOVING ASH
Remember, you do not need to riddle wood ash
during firing, but possibly only at the start when some
Primary Air is needed to aid the initial combustion.
Riddling allows mineral fuel ash to fall into the
collection pan below the fire bed to help maintain a
flow of Primary combustion air to the fuel. The ash
pan should never be allowed to over-fill as this will
limit the Primary Air flow and could cause excessive
heat build-up which could eventually warp or burn
out the grate.
Locate the operating tool in the slot at the front of
the ash pan to make a handle and lift the pan from
the stove. For safety reasons ash should be removed
when the stove is cold. If this is not always possible
then extra care should be taken and decorative and
combustible surfaces, such as laminate floors or
carpets, should be protected against potential
accidental spillage. Even if the ash appears to be cold
protective gloves should be worn and the refuse ash
placed in a non-combustible container. The ash could
still be hot with the possibility of hidden live embers
As you remove the ash from your home ensure that
it is covered to protect it from any draught or wind
which could blow the ash out of your container.
Wood ash can be composted or used in the garden.
The forked end of the tool is inserted underneath the ash pan grip
as shown above to create the ash pan handle.
INSTALLATION CHECK-LIST
This information is intended to outline the general
principles of installing your inset stove. However, as
each installation will vary and must comply with local,
national and European building regulations, which
could be different from country to country, it is
unfortunately not possible, nor is it intended, for
these guidelines to be comprehensive.
Legal Requirements
Please note that, not only is it a legal requirement to
ensure that your stove installation complies with all
applicable building regulations, it is also a requirement
of your Warranty that the stove is installed by a
competent person such as a Hetas or INFO registered
installer who will be fully aware of any building and
safety regulations which apply to stove installations in
your location.
Inset Boiler Stove Location Checklist
• The existing constructional hearth (the main part of
the hearth) is suitably constructed and is of a
thickness that conforms to all applicable building
regulations.
• The back hearth (the part of the hearth that the
inset stove sits upon and which is usually within the
fireplace recess or opening) is also suitably constructed
and conforms to all applicable building regulations.
• The superimposed hearth (the thinner, usually
decorative surface, which sits on the constructional
part of the hearth) is suitably constructed and
conforms to all applicable building regulations.
• The fireplace recess or opening is suitably
constructed and conforms to all applicable building
regulations and can accommodate the stove along
with the safe minimum operating distances required.
• Any adjacent walls, next to which the stove is
installed, are of a suitable thickness and are of non-
combustible material and conform to all applicable
building regulations.
• The air supply is sufficient for full combustion of the
stove’s fuel and the health and safety of the room’s
occupants. Any extractor fans inside the room should
be removed or permanently disabled. Note that in the
UK stoves above 5kW output require a permanently
open dedicated air supply within the room which
must conform to applicable building regulations. The
HF357i-B Precision Inset Boiler stove has been officially
rated at a maximum output of 12.6kW and therefore
the installation must incorporate an appropriately
sized air vent.
• The chimney is of sufficient height, is suitably
constructed and is in good condition and conforms
to all applicable building regulations regarding stove
installation. The minimum flue height required for the
Precision Inset is 4.5 metres (15’) from the hearth to
the top of the chimney terminal.
