2.3 Specific safety instructions

WARNING
If water discharges from the Temperature/
`
Pressure Relief Valve on the appliance,
isolate the electicity supply to the
appliance. DO NOT turn off any water
supply. Contact a competent Installer
for unvented water heaters to check the
system.
DO NOT tamper with any of the safety
`
valves fitted to the system. If a fault is
suspected contact a competent Installer.

`
any circumstances.
Where the inlet supply to the Pressure
`
Reducing Valve is routed through a heated
space and is fitted with a check valve or
other fitting that would prevent backflow,
high pressures can be experienced in the
inlet pipe due to warming that can cause
damage to the PRV or other fittings on the
inlet supply. In these circumstances, the
installation of a means to accommodate
expansion and thus limit the pressure rise
in the inlet pipe is recommended
