Ventilation Requirements
To carry out a risk assessment it will be necessary to grade the risks associated with
the property, including construction of property and ventilation. HETAS have designed a
risk assessment template that should accompany the table above and be completed at
all times.
It is not recommended that the fitting of the DEAS KIT is made into passive houses with
mechanical ventilation systems or extractors of any kind. In order for the stove to
perform efficiently and safely there should be an adequate air supply into the room in
which the stove is installed to provide combustion air. This is particularly necessary in
modern houses where drafts have been almost eliminated by double glazing etc. Fitting
the appliance into such properties requires
No possible means of air being taken from the room of the appliance eg:
Mechanical ventilation systems
Measures should be taken to ensure the air duct inlet does not become blocked
from snow, debris, and water ingress and not prone to collapse due to heat or
other effects.
The appliance fitted is to undergo stringent commissioning testing as set out in
HETAS Technical Note HETAS_TN_0020 v1.0 and detailed starting page 13.
