INSTALLATION

Temperature and Pressure Relief Valve

With solid fuel appliances it is not practicable to provide a sufficiently rapid reaction for shutting down fuel in the event of a sudden rise in water temperature and a temperature relief valve or preferably, a combined temperature and pressure relief valve should be installed to operate in the event of high water temperatures occurring.

See diagram below.

HOT WATER SYSTEMS

Before handing over the installation to the customer it is strongly recommended that the appliance is lit and the functioning of the chimney, hot water and heating system is checked.

A checklist (Pre-lighting Checks) appears in the Operating Instructions, but in addition to this the installer should:

Operate the heating system and set the pump head.

Balance the radiators.

Re-vent and ensure no air locks.

Check the circulation round the primary system and the heat leak radiator, particularly when the pump is running, to ensure circulation is not reversed.

Be sure that the chimney is operating and that ALL smoke and fumes are vented to the atmosphere through the chimney terminal.

Check all joints and seals.

Clean the outside of the appliance to prevent any stains becoming burnt on.

Check the flue draught which should read 1 - 2mm, or 0.1 - 0.2mbar.

The following details must be checked and completed in full by the installer at the time of installation. Please answer all questions as fully as possible. Arada Ltd can not be held responsible for chimney or installation.
