System Maintenance
Regular servicing will help to extend the life
of the water heater, and keep it operating
safely and efciently.
Your water heater warranty is not
conditional on completing the regular
servicing recommended in this manual.
The conditions applying to your water
heater warranty are set out on page 9 of
this manual.
Six Month Service:
This service may be carried out by the
owner.
1. Stand clear of the Pressure &
Temperature Relief (PTR) Valve drain
pipe outlet.
2. Open the PTR Valve for approximately
10 seconds by lifting the easing lever
on the valve. Conrm water discharges
to waste through the drain pipe.
3. Lower the easing lever gently and
check it closes correctly.

expansion control valve (if installed).
Other than this, personally inspecting or
servicing any part of the water heater is not
