Ducted heating units
As a result of recent news items concerning ducted heating fires, there may be some misinformation in relation to the cause of these fires.
THE FACTS ARE:
To date there has been no evidence to suggest that, fires have started solely due to the build up of dust in the ducting of the heating system.
Some fires have started due to lack of maintenance of the heating unit.
Some fires have started due to restricted airflow into the return air ducting around heating fan units. This is mainly caused by the build up of dust and lint in the return air grille.
The ducting itself may assist in spreading a fire dependent on its flammability rating, acting as an avenue for the transfer of flame and/or smoke.
If the ducting itself ignites as a result of a fire in the heating unit, fire can spread along its length, under floor spaces or in roof spaces.
THE FOLLOWING PRECAUTIONS WILL HELP PREVENT FIRES IN DUCTED HEATING SYSTEMS:
Have the heating unit regularly maintained by an authorised, registered tradesperson as per manufacturers’ specifications detailed in the warranty book/and on the heating unit.
Regularly vacuum the fascia/grilles/filters of the return air duct.
“Test run” the unit at the start of winter on a day when you are home. (Never start a heater and immediately leave it unattended.)
