2. Ignition:
Turn the water flow knob (make sure there is water
flowing out of the outlet pipe), the heater will turn on
with a" clicking" ignition sound. The burner is ignited
and hot water flows out instantly. If the water pressure
is too low, turn the water volume knob to "MAX."
position, if still there is no ignition, it is because the
water pressure is too low or the battery installed
incorrectly.
After initial installation or a change of gas cylinder, airmay remain in the gas pipe and it requires several
ignition attempts to push the air out of the pipe before
the gas can be ignited. If a problem comes up after
normal operation, turn off the water immediately. Try to
re-ignite after 10-20 seconds
Turn the water flow knob to regulate the water flow and
therefore the temperature. Turn the flame control knob
to regulate the flame of the burner and also thus control
the hot water temperature.
A burner control knob allows you to select the number
of burners in operation. Select 1 or 2 or both burners
depending upon the season. This feature saves
precious energy and costs.
Shut-off the water flow and the water heater willautomatically stop operating.
Test outlet water temperature
with back of your hand
before use. to avoid scalding.

Cautions for safety
Gas leak prevention
Always check all the gas pipe connections, with soap
solutions to check whether it has gas leak. In case of
gas leak, shut off the gas supply and open the
windows immediately. Under such condition, ignition,
switching on/off the electric power supply are strictly
prohibited to avoid explosion and fire (FIG.12)
Check whether the flame is extinguished after each
use. Always turn off the gas valve when not in use
(FIG.11)
Check the gas tube regularly, as it
may age and crack after long
period o f use. Replace it if
cracked. Under normal operations,
the gas tube should be replaced
yearly.
For LPG users, if the flame of the
heater is not stable, it may be caused by a defective
pressure regulator connected to the outlet of the
gas cylinder. In that case, stop using the heater
immediately and contact authorized gas service
technician.
For PNG users, if the flame of the heater is not stable,
it may be caused by the instability of the gas
pressure. Stop using the heater immediately andcontact the gas supply agency.
Fire accident prevention
Always shut off the main gas supply
valve before retiring to bed.
Do not place inflammables like towel
or cloth near the flue outlet or the air
inlet. (FIG.13)
Do not pile inflammables, explosives
or volatile materials near the heater.
(FIG.14)
For LPG users, do not place the
cylinder tilted or inverted or on its side.
Prevention of excessive Carbon
Monoxide concentration
As in all gas appliances like your cooking stove, the
burning of gas consumes large amount of air and
produces some amount of poisonous carbon
monoxide. Carbon Monoxide concentrations above
a certain level is injurious to life, therefore, the heater
must be fixed in a ventilated location. Keep exhaust
fans running, if provided or else, windows and. the
ventilation ducts always open. .
PNG users. When the gas pressure is insufficient,
the carbon deposit in the burner may increase and
affect the efficient use of the heater. In such case,
flame would turn from blue to yellow, Stop using the
heater and contact the gas agency or the service
center. The heater must be installed vertically.
Prevent injuries to the Eyes
Keep eyes away from the flame indicator window at
a minimum safety distance of 300 mm during
ignition. If the first attempt of ignition fails, wait 10-
20 seconds before the next attempt.
Prevent "no-water" Burning in the Heater
After each use, make sure that the flame is
extinguished when there is no water flow,. If the flame
still exists, switch off the gas valve immediately and
contact the service center, otherwise the heat
exchanger may be damaged due overheating.
Freezing Prevention
When temperatures are near 0 C, i t is
recommended that all residual water, in the water
heater is drained out after use, by removing the drain
valve and allowing the water to flow out. Re-Install
the drain valve before using the water heater again.
Freezing of water inside, will permanently damage
the heat exchanger.

After use and turning off the gas valve, drain outthe hot water in the gas water heater until cold wa te rflows out. Then turn off the water valve.
Dealing with the Abnormal Conditions
Put off heater when strong adverse wind blow into thebathroom from outside, causing the flame to beunstable. In case of abnormal burning (e.g. back fire ,flame out, yellow flame or black smoke, etc.), unusualsmell, noise etc., keep calm and turn off the gas valve
and contact the service center or the gas dealer.
Replacement of batteries
The normal life of a pair of batteries is 6 months innormal working conditions.
Preventing overheating scald
During or immediately after use, do not touch any partof the heater other than the knobs, especially theparts around the f lame check window.
The following things are normal
When the water pressure is lower than 0.03Mpa,(Less than 5 PSI) the heater cannot be ignited.
The drain valve dripping, When the water pressure istoo high, the drain valve will release the water so as toreduce the pressure to protect the heater.
When the heater is supplying hot water to severalpoints at the same time, the hot water flow would bereduced,
During use, the heater will automatically be turnedoff after 20 minutes of continuous use. This is a s afe tyfeature.
When the heater shuts off due to over temperature itwill not ignite immediately. Shut off the gas supply,allow the cold water to flow out for about 30 seconds(to cool and reset the thermal cut out) beforeattempting to reignite.
When the voltage of the battery is less than 2.1V, theheater will not ignite, replace the batteries.
Maintenance
Check the gas tube / pipe regularly for any defects.
Contact service center/ gas agency for any doubt.Clean the water filter mesh regularly.
Check for gas / water leak regularly.
When the flame turns from blue to yellow with blacksmoke, contact the service center immediately forhelp
It is recommended that, every six months, the heatexchanger and burners are checked and serviced bya qualified technician to ensure efficient working ofthe heater. Contact our authorised service center.
