Technical Details Intermittent Operation
Intermittent operation is when the appliance is used for short firing periods for example 45 minutes to 2 hours.
This is a common operation in warmer weather such as cold spring evenings. The information provided below
where indicated as HETAS approved is from the current CE standards EN 13240:2001 and EN 13240 A2:2004.
The test fuel is wood.
* Air requirement equivalent area. Building regulations Document J, advises that an air supply should be
installed for appliances with a heating output over 5kW. Document J indicates that there should be sufficient
advantageous air for heating outputs below this amount. With modern properties this may not always be the
case and/or more free air may be required. Continuous or intermittent operation will result in different heating
outputs due to the nature of the fuel and the appliance. If in doubt increase the suggested area listed or contact
your HETAS approved engineer for assistance.
