4 Operation
Warning.
Risk of being scalded by hot water.
Incorrectly set hot water temperatures and
hot water in the lines may lead to scalding.
▶Check the hot water temperature with
your hand.
Warning.
Risk of burns caused by touching the
sight glass!
▶Avoid direct contact with the heat-con-
ducting sight glass.
Caution.
Risk of material damage caused by an
interrupted water supply.
▶Ensure that the water supply cannot be
interrupted.
4.1 Cabinet-type casing
Enclosing the product in cabinet-type casing requires compli-
ance with the applicable design instructions.
If you require cabinet-type casing for your product, consult
a heating specialist company. Never, under any circum-
stances, enclose the product yourself.
4.2 Preparing for start-up
1. Ask the competent person who installed the product to
explain to you where these isolator devices are located
and how to handle them.
2. Open the gas isolator cock fully.
3. Open the cold water stop valve that is set on-site.
4.3 Starting up the product
▶Only start up the product once the casing has been com-
pletely closed.
4.4 Switching on the product
2
1
1. Turn the rotary power switch (1) clockwise to the igni-
tion position (lightning symbol) and press it.
2. Press down and hold the rotary power switch in this
position and actuate the Piezo igniter (2) by pressing
it several times.
◁Each time the Piezo igniter is pressed, this creates
one single ignition spark. The ignition flame is ig-
nited.
3. While the ignition flame is burning, hold the rotary
power switch in this position for another 10-15 seconds.
4. Observe the ignited ignition flame through the sight
glass. If the product was shut down for an extended
period, air may have accumulated in the ignition gas
line. In this case, repeat the ignition procedure.
Note
If you notice leaks in the hot water pipes
between the product and the draw-off points,
you must immediately close the cold-water
isolation valve that was set on-site.
Have the leaks eliminated by a competent
person.
4.5 Drawing hot water
1. Open the hot water valve at the draw-off point.
◁The product automatically starts up.
Conditions: No hot water is supplied.
▶Ensure that any stop valve that is installed upstream of
the hot water valve is completely open.
▶Ensure that the pilot flame has ignited.
▶Remove the filter that is installed in the hot water valve
and check the filter for dirt and limescale.
▶Use a descaling solution to remove the limescale from
the filter.
2. Close the hot water valve on the draw-off point.
◁The product automatically shuts down.

Troubleshooting 5
0020271944_00 atmoMAG Operating instructions 7
4.6 Setting the domestic hot water temperature
2
1
1. Turn the temperature selector (1) clockwise to decrease
the domestic hot water flow rate.
–The domestic hot water temperature is thereby af-
fected (increased).
2. Turn the rotary power switch (2) anti-clockwise to in-
crease the burner output.
–The domestic hot water temperature is thereby in-
creased.
3. Turn the temperature selector (1) anti-clockwise to in-
crease the domestic hot water flow rate.
–The domestic hot water temperature is thereby af-
fected (reduced).
4. Turn the rotary power switch (2) clockwise to decrease
the burner output.
–The domestic hot water temperature is thereby re-
duced.
Note
If you increase the domestic hot water flow
rate and turn the rotary power switch anti-
clockwise, the gas consumption is increased.
4.7 Modulation
The burner output (gas flow rate) is continually and auto-
matically matched to the domestic hot water flow rate in the
range between the preselected setting on the rotary power
switch and the product's lowest possible output (approx.
35%). As a result, the domestic hot water temperature is
kept at a constant.
5 Troubleshooting
5.1 Detecting and eliminating faults
A fault is present if the product does not generate any hot
water. As the end user, you may only proceed as follows:
▶Use the sight glass to check whether the ignition flame is
still burning.
▶If the ignition flame goes out, switch the product on
(→Page 6).
▶If the ignition flame repeatedly goes out or no hot water is
generated, contact a competent person to eliminate the
problem.
5.2 Eliminating faults in the product
▶If the product was blocked by a safety device, wait ap-
prox. 10 minutes and then start up the product again.
▶If the product is repeatedly blocked by a safety device or
does not start up, contact a competent person to have
the fault eliminated.
▶Only start the product up again once the fault has been
eliminated by a competent person.
6 Care and maintenance
6.1 Maintenance
An annual inspection and biennial maintenance of the
product carried out by a competent person is a prerequisite
for ensuring that the product is permanently ready and
safe for operation, reliable, and has a long service life. The
inspection may require maintenance to be carried out earlier,
depending on the results.
6.2 Caring for the product
▶Clean the casing with a damp cloth and a little solvent-
free soap.
▶Do not use sprays, scouring agents, detergents, solvents
or cleaning agents that contain chlorine.

7 Decommissioning
8Operating instructions atmoMAG 0020271944_00
7 Decommissioning
7.1 Temporarily decommissioning the product
1
▶Turn the power switch (1) clockwise from the position for
"ready for operation" as far as it goes.
▶Close the gas isolator cock that was set on-site.
◁The gas supply to the burner on the gas-fired instant-
aneous water heater is now blocked.
▶Close the cold water stop valve that is set on-site.
7.2 Having the product permanently
decommissioned
▶Have a competent person permanently decommission
the product.
7.3 What to do if there is a risk of frost
1
If there is a risk of frost, it is necessary to protect the product
against freezing. To do this, you must drain your gas-fired
instantaneous water heater.
▶Temporarily decommission (→Page 8) the product.
▶Undo the drain screw (1) with the sealing ring.
▶Open all of the domestic hot water tap fittings that are
connected to the product so that the product and line
drain until they are completely empty.
▶Leave the domestic hot water tap fittings and the drain
screw open until the product is started up again when the
risk of frost has passed.
▶When subsequently filling the product, only start it up
again once the water that flows out of the opened do-
mestic hot water tap fittings has no bubbles after the
cold-water isolation valve that is set on-site is opened.
8 Recycling and disposal
▶The competent person who installed your product is re-
sponsible for the disposal of the packaging.
If the product is labelled with this mark:
▶In this case, do not dispose of the product with the
household waste.
▶Instead, hand in the product to a collection centre for
waste electrical or electronic equipment.
If the product contains batteries that are labelled with
this mark, these batteries may contain substances that are
hazardous to human health and the environment.
▶In this case, dispose of the batteries at a collection point
for batteries.
