on the water faucet. If no flame is generated
after ignition, please close the faucet and turn
it on again after 10 minutes.
Note: If the heater is not in operation for a
long period, air may enter the gas system.
In such case, please repeat the ignition
procedures above for several times.
Power adjustment
Ga sregulation knob can be used to adjust
the volume of gas circulation. This operation
can adjust volume of gas circulation and the
temperature of hot water:
When gas supplied at rate pressure, the
output power of maximum gas is the rated
output power. Please refer to the gas
consumption in the specification table.
Adjustment of water temperature
The temperature regulation knob can be used
to adjust the volume of water circulation. This
operation can change temp- erature of hot
water. If you want to increase the temperature
of hot water, please turn the regulator of water
temperature clockwise. If you want to reduce
temperature of hot water, please turn the
regulator of water temperature counterclock-
wise.
Please keep the sealing valve at the cold
water inlet completely open. Don’t reduce
the water circulation by means of closing the
valve.
