WARNING

#

If water discharges from the temperature/pressure relief valve on the cylinder shut down the boiler. 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.

#

DO NOT bypass the thermal cut-out(s) in any circumstances.
