Know what you notify
Know what you notify
There are occasions where you might be asked to install something out of the ordinary. Whilst they might look unique, you need to make sure you are applying your knowledge of the Building Regulations.
When installing a solid fuel, wood or biomass appliance you must satisfy yourself that the installation and associated works meet all the relevant Building Regulations (which in England or Wales are primarily Regulations 4 and 7).
The following points must be considered ahead of any new installation.
- The relevant Building Services Compliance guide must be followed for any new combustion appliance. For instance, a domestic solid fuel fuel dry room heater (categories E1 to E3) must have gross efficiency of at least 65% – click here for more information.
- Ensure the appliance is sized correctly (nominal output) to meet optimum efficiency in accordance with Part L of the Building Regulations
- Flues and hearths must be sized and positioned correctly for the specification of that appliance
- Manufacturers clearance distances to combustibles are maintained at all times to comply with Requirement J4 of the Building Regulations (see also Approved Document J)
- Other manufacturer prescribed guidance is followed in terms of installation and use
Installers would only be able to verify these caveats above by one of the following means;
- Checking against a listing (in the HETAS Guide/website search for example)
- Taking verification of efficiency, output & clearances from the CE data plate (which would also give you the name/model)
- Taking verification of efficiency, output and clearances from Declaration of Performance (again you would need to know the name and manufacturer of the appliance)
All of these steps would require knowledge of the appliance model. Without obtaining this important pre-installation information, there is no means of confirming a compliant installation. All of this information is only available in areas that give the appliance/model reference. Under no circumstances should a combustion appliance be identified as “unknown”, whilst at the same time ticking the “meets Building Regulations” box on HETAS notifications.
Completing the certificate
When completing the HETAS Certificate of Compliance please ensure you have all the appliance and chimney/flue details in order to fully complete the notification. Notifications must identify the appliance installed.
From 1st July 2013 any solid fuel products are required to have a CE mark under the Construction Products Regulation. The requirements for manufacturers are straightforward – everything sold from July 1st 2013 must be CE marked. The only exception is for appliances which were manufactured and had been placed on the market prior to that date to allow for a transition period.
You should also ensure that any work carried out is within the scope of your registration with HETAS in order for it to be notified via HETAS. Detailed guidance on this can be found in the HETAS Technical Area.
The HETAS Technical Helpline is available to registrants during office hours on 01684 278194 or via email on email@example.com. Additional guidance is available in your Technical Handbook (Section 2) and via the HETAS Guide.
