Approved Flue System; Installation Precautions - Lochinvar HERALD HCB46CE Installation Manual

APPROVED FLUE SYSTEM

For Concentric and Twin pipe flue systems only the Lochinvar supplied M&G flue system must
be used
The approved flue system is not suitable for use external to the building. If external routes
cannot be avoided, a flue system manufacturer should be consulted to supply a suitable
alternative.

INSTALLATION PRECAUTIONS

The approved flue system is rated to 120C max. To prevent the exhaust temperature exceeding this, the

appliance is supplied with a flue gas temperature sensor.
This must be fitted during the installation of the flue system. Failure to do so may lead to
severe personal injury, death or substantial property damage.
The Boiler must not be operated unless the complete flue system is installed. This includes
the Boiler connections, concentric adaptor (if required) flue pipes, air ducts (if required) and
terminals. If discharging at low level, a suitable flue guard must be installed.
During assembly precaution should be taken to ensure that the internal sealing ring is seated
correctly.
Due to the close tolerances in the flue system, it may be necessary to use a twisting action to
fit the joints together. No lubrication other than water should be used.
