Prevention of Fire
1. Absolutely do not go out or go to bed with the water
heater on.
2. Do not place any combustibles near the draft hood of
the water heater. Do not use towel, clothes and other
things to cover the vent.
Prevention of Carbon Monoxide Poison
1. A large amount of oxygen is needed when the water
heater is used. Therefore, the site where the water
heater is installed must have enough air for
supplement and be well-ventilated. The room where
the water heater is installed must have a fixed open
air intake. The closed doors and windows cannot be
classified as effective air intakes.
2. A large amount of exhaust gases will be vented when
the water heater is used. Therefore, the water heater
must be installed with a smoke exhaust pipe to vent
the exhaust gases produced during burning to the
outdoors.
3. When the manufactured gases or natural gases are
used, if the gas supply pressure is too low, there may
result in tempering, hence affecting the normal
operation of the water heater. At this point, the flame
will turn from blue to yellow and the discharge of
Carbon Monoxide will increase significantly. Stop
using the water heater at once.
Other cautions:
1. Non-potable: Since there is water stored in the water
heater for a long time, the hot water provided by the
water heater is not potable, just used as non-potable
water.
2. Freezing prevention: When the water heater is used
in cold areas where the ambient temperature is below
0
°C
, the water stored in the water heater must be
drained to prevent the water heater is damaged,
since the water will expand when it freezes. The
water can be drained as follows:
a. Switch the water temperature regulation knob to
“Low” after shutting off the water inlet valve.
b. Switch on the hot water outlet valve.
c. Screw off the drain valve. After draining the water,
screw on it and shut off the hot water outlet valve.
Since there is a rubber gasket in the drain valve,
screw it with great force.
3. During ignition, it is strictly forbidden to observe the
ignition with the eyes closely near the viewport. The
distance between the eyes and the viewport should
be at least 300mm.
4. When the water heater is not used for a long period of
time, take the dry batteries out from the battery case
to prevent the battery case from corrosion due to the
damage to the batteries, hence leading to poor
contact and affecting the use of the water heater.
There must be a
fixed open air intake.
