SAFETY PRECAUTIONS
Safety precautions are for ensuring safe and correct use of this
product, and for preventing injury to the operator and other
people or damage to property. You must observe these safety
precautions. Also, be sure to read and understand the contents
of this user’s manual.
WARNING
Warnings are indicated when mishandling this prod-
uct might result in death or serious injury to the user.
CAUTION
Cautions are indicated when mishandling this prod-
uct might result in minor injury to the user, or only
physical damage to this product.
WARNING
High-voltage currents run through the secondary-side
terminals. Never touch them while the circuit is ener-
gized. There is a risk of electric shock.
Before removing, mounting, or wiring the
ATN110A-1, be sure to turn off the power to the
ATN110A-1 and all connected devices. Failure to do
so might cause electric shock.
Connect the ground terminal to a D-class ground
(resistance of 100 Ω or less) or better. Electric noise
may infrequently occur, adversely influencing other
equipment, or an electrical leak may occur, creating
an electric shock hazard.
CAUTION
Adjust the gap between the discharge electrodes and
also the air velocity between the electrodes so that
they are within the recommended values. Exceeding
the recommended values will raise the secondary
voltage, possibly burning out the transformer.
On the secondary side of this transformer, use the
specified type of wire with a length of no more than
1.5m. A wire exceeding this length on the secondary
side will raise the internal temperature of the ignition
transformer, possibly causing it to malfunction.
Keep the wiring for this transformer separate from
other wiring and piping. Contact or mixing of the
wiring of this transformer with other wiring may gen-
erate inductive noise, causing other equipment to
malfunction.
Only an experienced specialist who has knowledge
and expertise regarding combustion equipment and
combustion safety equipment should install, wire, in-
spect, adjust, and service this transformer.
Periodically clean the secondary-side insulators of
this transformer and the insulators of the spark rods
to keep them clean. Accumulation of soot or dust, or
condensation of moisture, may prevent normal dis-
charge, resulting in ignition failure of the burner.

OVERVIEW
■Feature
•A transformer used for ignition of gas burners. Changing the
position of the internal lead on the primary side makes this
transformer compatible with either 100Vac or 200Vac.
•Wiring terminals are provided on both the primary and second-
ary sides.
•A drip-proof case is available.

MOUNTING/WIRING
WARNING
Before removing, mounting, or wiring the
ATN110A-1, be sure to turn off the power to the
ATN110A-1 and all connected devices. Failure to do
so might cause electric shock.
Connect the ground terminal to a D-class ground
(resistance of 100 Ω or less) or better. Electric noise
may infrequently occur, adversely influencing other
equipment, or an electrical leak may occur, creating
an electric shock hazard.
CAUTION
On the secondary side of this transformer, use the
specified type of wire with a length of no more than
1.5 m. A wire exceeding this length on the secondary
side will raise the internal temperature of the ignition
transformer, possibly causing it to malfunction.
Keep the wiring for this transformer separate from
other wiring and piping. Contact or mixing of the
wiring of this transformer with other wiring may gen-
erate inductive noise, causing other equipment to
malfunction.
Only an experienced specialist who has knowledge
and expertise regarding combustion equipment and
combustion safety equipment should install, wire, in-
spect, adjust, and service this transformer.
Be sure to install this transformer in close contact
with the mounting plate, and be sure that the ground
terminal of this transformer is connected electrically
to other equipment. If this transformer is not firmly
attached to the mounting plate, high-frequency
noise will be generated, causing other equipment to
malfunction.
Connect wiring in accordance with the provided spec-
ifications and criteria.
Connect the power source to the equipment as the
last step. Otherwise there is a risk of electric shock or
equipment damage.
■Mounting
●Standard installation direction
Install this transformer with the label facing upward.
●Connection of the ground terminal
Make a good electrical connection between the ground termi-
nal of this transformer and the combustion equipment.

■Wiring
•The primary-side wiring of this transformer is factory-con-
figured for use at 200Vac. To use this transformer at 100Vac,
reconnect the wiring as shown in the figure below.

•The use of a high-voltage cable made for neon tubes or automo-
biles (JIS C 3405) is recommended. If there is a problem with
radio noise, use a cable designed for noise prevention.
ADJUSTMENT
CAUTION
Adjust the gap between the discharge electrodes and
also the air velocity between the electrodes so that
they are within the recommended values. Exceeding
the recommended values will raise the secondary
voltage, possibly burning out the transformer.
■Points to check before use
•Check that this transformer is compatible with the supply
voltage.
•Check that this transformer’s discharge gap is the recommended
value of 2mm and that the air velocity between the electrodes is
the recommended value of 5 m/s or less. Note particularly that
an appropriate discharge cannot be obtained if the gap is either
too small or too large.
MAINTENANCE/INSPECTION
CAUTION
On the secondary side of this transformer, use the
specified type of wire with a length of no more than
1.5 m. A wire exceeding this length on the secondary
side will raise the internal temperature of the ignition
transformer, possibly causing it to malfunction.
Only an experienced specialist who has knowledge
and expertise regarding combustion equipment and
combustion safety equipment should install, wire,
inspect, adjust, and service this transformer.
■Periodic inspection
Periodic maintenance, including cleaning and replacement, is re-
quired to maintain normal sparking.
•Check that the gap and air velocity between the electrodes of
the spark rod of this transformer are the recommended values.
Sparking causes the gap between the electrodes to grow gradu-
ally larger.
•Check that the wiring connections are not loose.
•Clean the spark rod. If there is soot or the like on its tip, the
spark rod may fail to spark.
•Clean the transformer, insulators, etc., to prevent carbon
tracking.
•Check secondary high-voltage cables for deterioration.
Insulation breakdown may be caused by moisture (hydrolysis)
and other factors.
