After Installation
TESTING AND COMMISSIONING PRIOR TO FIRST USE
This is carried out using a flue flow test as described in BS EN 15287 Parts 1 & 2, with reference
to the appropriate appliance type.
APPLIANCE OPERATION
If the appliance is slumbered overnight or for longer periods then it is advisable to run the
appliance at controlled high fire condition for a period of at least 30 minutes. Prolonged
slumbering of the appliance is a contributing factor to a system chimney failure. It is important to
maintain sufficiently high flue gas temperatures in order to avoid condensate and acid corrosion
problems, and to ensure complete combustion of the fuel.
MULTI-FUEL APPLICATIONS
Multi-Fuel refers to an appliance which may be used to burn either seasoned wood, or approved
solid fuels. These fuels should not be mixed, as this increases the risk of deposits being built up
in the liner.
MAINTENANCE
Each chimney must be designed to allow for easy inspection; sweeping should be carried out by
competent persons. On solid fuel applications a list of HETAS registered sweeps can be found at
www.hetas.co.uk. Chimney flue cleaning and inspection require the use of appropriate tooling –
under no circumstances should chemical cleaners or mild steel tools be used to sweep stainless
steel chimneys. Mechanical sweeping methods such as Rodtech, Rodstation and Gardus, which
have been tested and approved by Schiedel Chimney Systems may be used. Cleaning/inspection
of any chimney system should be carried out at least once a year, along with maintenance of the
appliance, but it is recommended that chimneys serving solid fuel appliances be swept at least
twice a year, at the end of the heating season to remove any deposits, which may have built up
during the season, and prior to the start of the next heating season to ensure that the the flue
way is clear of any blockages such as birds nests etc.
We would advise that monthly checks are carried out to ensure that there is no build up of any
deposits in the flue way of the connecting flue pipe or system chimney.
FUEL STORAGE AND USAGE
Where solid fuels are being used, correct storage is critical and fuels must be kept dry. Wood
must be seasoned prior to use, with a maximum moisture content of 20%. Only approved
fuels should be used. Refer to HETAS list for details on www.hetas.co.uk.The fuel used must be
suitable for the appliance - please refer to manufacturer’s instructions.
