6 how it works Kelvinator gas continuous flow hot water system
When a hot water tap is turned on, cold water begins flowing
through the gas continuous flow hot water system and out
of the hot water tap. A flow sensor inside the water heater
detects that there is water flow and the computer opens the
internal gas supply valve, ignites the burner and starts the
internal fan. The water circulating inside the water heater
goes through a heat exchanger that absorbs the heat created
by the flames of the burner and transfers the heat into the
water circulating through it. The internal computer modulates
the gas supply valve and the water flow to produce the right
amount of hot water to the correct temperature. When the
hot water tap is turned off, the unit detects that the water
flow has stopped and closes the gas supply valve, stopping
the burner. The internal fan continues to run for a little while
longer and then shuts down.
Your gas continuous flow hot water system may be installed
on its own or part of a gas boosted solar hot water system.
Turning on your gas continuous flow hot water system
If your gas continuous flow hot water system has been turned
off after commissioning or shut down for a period of time
follow these instructions:
• Ensure that power is switched off to the water heater or
that it is unplugged
• If the system has been drained, ensure that the drain plug
and filter located on the cold and hot water lines have
been screwed back in place (hand tighten only)
• Open any hot tap or fixture in the house
• Open the cold water isolation valve located on the inlet to
the water heater and check for leaks
• Once water is flowing freely from the open hot tap or
fixture, indicating that all air has been dispelled from the
system, close the open hot water tap or fixture
• Open the gas isolation valve located on the inlet to the
water heater and check for leaks
warning
If you smell gas or a gas leak is detected after opening the
gas isolation valve, immediately close the valve. Do not turn
on power to the water heater and keep potential ignition
sources away. Call a service technician to inspect and repair
the leak.
• Plug in the power cord to the power outlet (if it isn’t
already) and turn on the power supply to the outlet.
• Turn on the remote controllers (if fitted) by pressing the
"On/Off" buttons.
• Press the "Priority" button on the controller to be used
and set the desired temperature using the "+" and "-"
buttons.
Your gas continuous flow hot water system is now ready to be
used and will operate automatically when a hot tap or fixture
is opened.
Turning off your gas continuous flow hot water system
If you wish to turn off your gas continuous flow hot water
system follow these instructions:
• Turn off the remote controllers (if fitted) by pressing the
"On/Off" buttons
• Switch off electrical supply at the power outlet that the
water heater is plugged into
• Close the gas isolation valve located on the inlet to the
water heater
• Close the cold water isolation valve located on the inlet to
the water heater.
Note: If there is a risk of freezing conditions, do not switch off
power to the water heater unless it is drained of water first.
Please see the section on freeze prevention on page 9 of this
manual for more information.
