SPECIFIC INSTALLATION INFORMATION
Clearances
If the stoves are to be installed adjacent to materials that can catch fire like
wood then the following clearances must be adhered to:
STOVE
Helios
The stove can be recessed into a suitably sized fireplace built from non-
combustible materials, but a permanent free air gap of at least 100mm should
be left around the sides and top to obtain maximum heat output and for access
to the rear of the stove.
It is possible to fit the stove with less clearance around it – down to 50mm, but
the non-combustible material around it must be at least 150mm thick. This is
normally achieved when installing into a standard brick-built chimney breast
with double thickness walls to the rear and sides of the builder's opening. Take
care that the wall finish is suitable to withstand temperatures of up to 200
Hearths
Allow an apron of at least 225mm at the front of the stove and 150mm on either
side. Care should be taken to level the stove and secure the hearth. If existing
floors do not have adequate load bearing capacity then suitable modifications
must be adopted. All other standard thickness hearths are suitable too.
When the stove is in the desired position, fix the brackets provided to the back
feet and level the stove using the levelling screws, then mark the hearth through
the holes, remove the stove, and drill and plug the hearth for securing the stove.
Ventilation into a Room for Combustion Air is an Essential Requirement.
Any apertures provided for this purpose must not be restricted or blocked.
Flues Without a Flue Draft Stabiliser
When installing without a flue draft stabiliser into houses built before 2008, no
additional permanent ventilation will be required. Houses built after this date
will require additional means of permanent ventilation direct to outside of at
2
least 2750 mm
. Gallery Vents can be used for this.
