Commissioning the System
This water heater uses several staged
valve units to control the flow of water
through the gas booster and solar
plumbing circuits.
When the water heater is switched on,
both the valves and gas system need to
be initialised. This process takes several
minutes to complete.
Please observe the following system
startup process when the unit is
commissioned.

OFF
.

Warning: Warning: Do not
turn power on until the
storage tank is full.

ON
.
• There will be a delay of up to 2
minutes before the fan will start.
During this time, a small amount of
water may drain from the system.
This is normal.

seconds, the gas booster will start.
• Commissioning the water heater is
now complete.
