A thermostatic mixer should be installed in the system to prevent the risk of scalding.
If there are leaks found in the system, shut off the cold water stop valve from the main
supply and contact a competent person immediately.
WHAT IS BENCHMARK?
Benchmark places responsibilities on both manufacturers and installers. The purpose
is to ensure that customers are provided with the correct equipment for their needs,
that it is installed, commissioned and serviced in accordance with the manufacturer’s
instructions by competent persons and that it meets the requirements of the appro-
priate Building Regulations.
The Benchmark Checklist can be used to demonstrate compliance with Building Reg-
ulations and should be provided to the customer for future reference. Installers are
required to carry out installation, commissioning and servicing work in accordance
with the Benchmark Code of Practice which is available from the Heating and Hotwa-
ter Industry Council who manage and promote the scheme. Visit www.centralheating.

WATER SUPPLY
The performance of any unvented system is only as good as the mains water supply
available. To this eff ect the maximum possible water demand should be assessed,
with the knowledge that the mains supplies both hot and cold services
simultaneously.
The water heater itself operates at a pressure of 3 bar, controlled by the inlet control
set, and is capable of delivering over 50 litres per minute. The high quality inlet con-
trol set has been designed to make the most of the fl ow rates available.
The water supply should be checked to ensure it can meet these requirements. If
necessary, consult the local water authority regarding the likely pressure and fl ow rate
availability.
Consideration should be given to upgrading existing ½” (15mm) cold mains pipe-
work to a larger size if the recommended minimum pressure/fl ow rate is not being
achieved. JOULE recommend that primary pipework used has a minimum diameter of
22mm to ensure low pressure loss.
Note: A high static (no fl ow) mains pressure is no guarantee of good fl ow availability.
In a domestic installation 1.5 bar and 25 l/min. should be regarded as the minimum.
The maximum mains pressure that the inlet control set can cope with is 10 bar.
