Safety Information

Important
The PTR Valve and its drain outlet pipe
must not be sealed or blocked. It is
normal for the PTR valve to leak a small
amount of water during heating cycles.
Danger
Failure to operate the relief valve easing
lever at least once every six (6) months
may result in a problem with the water
heater and in some cases the tank may
explode.
