NOTE: Whenever high temperature water is required for continuous demand, lessen the flow
rate. Whenever low temperature water is required, the flow rate may be increased.
1. Press "POWER SWITCH" to ''OFF'' position. All lamps will go out.
2. Close the fuel tank valve.
In order to prevent any kind of damage or leaks caused by freezing, keep the pipes heated at
all times, as specified below.
CAUTION: In order to prevent the water heater from being broken or develop a leak,
regardless of being used in a cold region or in a warm or hot region, the water
supply piping, hot water supply piping, drain pipe, check valve, valves, pressure
relief valve and pressure reducing valve are to be protected with sufficient
insulation materials (by wrapping with heat insulation or by equipping an freeze
prevention heater).
1. OPERATING AT HIGH TEMPERATURE
CAUTION: Risk of scald injury. Before changing temperature setting make sure that the
water heater is not being used by any of your family at any place in the house.
Set the Thermostat to the ''HIGH'' position, and press "POWER SWITCH" to ''ON'' position.
NOTE: Since this method cannot prevent the water inside of the piping from being frozen,
sufficient insulation measures are to be given according to the requirements
mentioned in the above cautions.
