Heating and hot water piping installation

The exposed pipes shall be heat insulated with the
insulation material.
The exposes pipes may get frozen in the winter.
If the water supply pipe is frozen, the hot water is not
supplied. When the heating pipe has run out of water, the
water is not supplemented. Consequently, the boiler can
not operate normally.
Fix the parts of the boiler pipes with appropriate tools,
prior to piping installation.
Do not exert excessive force on the pipe during the
installation, Damages on the parts may cause a water leak.
Be sure to use the insulation flange on the heating
inlet and outlet in case of installation of the copper
pipe (the hot water inlet and outlet for a boiler
dedicated for hot water supply).
Failure to use the insulation flange may cause rapid
corrosion (rusty water).
We do not take the responsibility of the problems arising from
failure to use the insulation flange.
Do not use water, other than the tap water, for the
boiler.
Salt content in the sea water or spa water may accelerate
corrosion and shorten the life of the boiler.
We do not take the responsibility of the problems caused by
using water, other than the tap water.
Install the pipes as illustrated in the standard pipe
drawing.
Failure to install the pipe as illustrated in the standard
piping drawing may deteriorate the efficiency of the
boiler and the circulation of the heating water, which
may result in a boiler malfunction.
