OVERFLOW PIPE
Overflow pipes may be extended from the water heater, but must not be less
than 19.1mm (¾”) O.D. copper tube – not more than 10 metres in length. Right
angled bends must be limited to no more than three. The extension must fall
from the overflow outlet, should not be looped, and shall discharge at a visible
point where water flow will not cause damage to property or injury to persons.
This Pipe Must Not Become Blocked Or Obstructed.
FILLING THE WATER HEATER BY LIFTING THE VALVE LEVER
N.B. – Turning on the Stopcock or Duo valve alone does not fill the heater.
Power must not be turned on until the water heater is filled with water, and a
satisfactory megger reading is obtained.
Open the cold water isolating stopcock to the water heater.
Operate the lever on the combination pressure relief and non-return valve. This
allows the water to bypass the valve and fill the main tank. Water will flow from
the overflow when the tank is full.
DRAINING THE WATER HEATER
Turn the power off.
Turn off the cold water supply to the heater.
Check that vent and overflow pipes are unobstructed to avoid collapsing the
tank.
To drain the tank, remove the drain plug and attach a hose to the water heater.
Rake the other end of the hose to a Drain.
