Ventilation Requirements
1. Close all external doors and windows, ensure all openable ventilators are closed.
2. Open the appliance door and with a smoke match/pen (15 sec burn time) pass over
the top and side edge of the opening of the combustion chamber, observe and record if
the smoke/combustion products are drawn into the chimney or spill back into the room.
Once the smoke is extinguished, close the appliance door
3. Repeat this test with all extraction fans running and internal doors open connecting
the room the appliance is installed in to the extraction device(s) (see extraction test
above)
Note: If smoke or combustion enters the room, then additional ventilation may be
required to compensate for the extraction device(s).This can be tested by gradually
opening a window and observing the relevant smoke patterns during operation.
If the smoke continues to fail to draw up the flue, or fails with additional ventilation
beyond that advised by ADJ Table 1, thoroughly inspect the flue/chimney and
termination for other faults.
Check the appliance/flue/chimney draw with a flue draught gauge and ensure draught is
within manufacturer’s guidelines. If no gauge is available, or no draught reading is
given, you can test with smoke as a “safety check” but there is no substitute for using
the correct tools and undertaking the correct tests
Commissioning is the final stage of an installation and intended to evidence that the
appliance works safely at the time the commissioning takes place. All dedicated
external air supply installations are subject to the relevant commissioning and site
testing provisions as required for under Building Regulations and are to be notified
through the HETAS CPS scheme, where a certificate of compliance is to be issued, a
copy retained by the installer and a copy left with the consumer for their records.
The commission procedure detailed above should be followed to confirm compliance for
DEAS appliances. Further supporting information on commissioning may be available
from recognised product specific manufacturer's instructions, and should be referenced
during the commissioning process.
A copy of the form should be left with the consumer and a copy retained by the installer
for their records
There must not be an extractor fan fitted in the same room as the stove as this can
cause the stove to emit fumes into the room. If the extractor fan is fitted within a large
open plan living area then the tests above should be carried out as a minimum.
Broseley Fires do not guarantee the appliance will pass its spillage test in such cases.
