spark, may cause a fire
In preparaion for the unexpected gas leak, be sure
to install the gas leak alarm device and the gas

or spark, may cause a fire
Be sure to check the gas to be used for the product
prior to gas piping installation.
Use of the gas, other than the one specified on the name plate
on the front of the boiler, may cause incomplete combustion,
eventually leading to a fire or explosive ignition.
Install the gas holder, if used, in the well-ventilated
outdoor without above ground high voltage power
line. The gas holder shall be fixed not to fall down
on the ground.
If the gas holder falls down or gets in contact with the high
voltage power line, an explosive accident may occur.
