USING METHODS
Cautions Handling articles Wrong
• Heaters which use NG and TG
must use the gas type which the
heater is designed to use,
different type of gas or the same
gas in different place must not
be used confusedly.
Fig. 21
• Always check the gas rubber
pipe and change the pipe every
year to avoid gas leakage due
to crack.
• If the flame goes unsteadily, stop
using the water heater and contact
the qualified service facility for
repair or adjustment.
Fire prevention
• Do not leave alone the water

heater still in operation.
• In case of power failure or water failure, turn off the gas valve and water inlet valve.
• Do not place towel or clothes on top of the water heater. (Fig. 21)
• Do not store inflammables, explosives or volatiles near the water heater. (Fig. 22)
• Never incline the gas tank or make it upside down, the fluid gas is easy to flow into the heater
and cause fire accident.
Monoxide toxicosis prevention
• This product is forcedly exhaust the combustion product and inhale the air needed for
combustion through the flue, so a flue must be installed in the outlet of the heater to
completely discharge the combustion product to aoutdoors and inhale combustion air from
outdoors so as to keep the indoors air fresh and prevent incomplete combustion. Otherwise, it
will cause danger or even death.
• Too low or too high gas pressure leads to abnormal combustion. At that moment, stop using
the water heater until the gas pressure is normal.
• Dust and accelerated carbon would block the heat exchanger due to long time use, and affect
the combustion perfomance, cause the monoxide increase obviously. So, contact the qualified
person to clean and clear the dust and accelerated carbon every half year to ensure the
combustion product discharged smoothly.
• The heater must be installed vertically, if inclined, it will make the flame touch the heat
exchanger and cause monoxide increase obviously.
