The chimney/flue to which this appliance is being
connected must be swept and examined for
soundness prior to installation. Remedial action
should be taken if required, seeking expert advice
if necessary. Where the chimney is believed to
have served an open fire installation it is possible
that a higher flue gas temperature from a closed
appliance may loosen deposits that were firmly
adhered, with the consequent risk of flue
blockage. It is therefore recommended that the
chimney be swept a second time within a month
of regular use after
The chimney can be checked, before the appliance is installed,
with a smoke match. If the chimney doesn’t pull the smoke it
may suggest the chimney needs attention.
This test is only a guide as an apparently poor flue
may improve once the appliance is installed, lit and
the flue is warmed. If, once the appliance is installed
there is any doubt that the chimney is providing an
adequate draught, a flue draught reading should be
taken.
