UN-VENTED SYSTEM
It is the law that all unvented hot water systems be installed by an approved installer.
If the Lochinvar SST is to be used in an unvented arrangement, the system should follow the guidance
given in BS6700 and must comply with The Building Regulations: Part G3 in England and Wales, P5 in
Northern Ireland and P3 in Scotland. A kit of components that have been suitably sized for the
unvented or boosted operation of the appliance is available from Lochinvar Limited. For further
information, contact Lochinvar Limited.
