• Installation of water and gas pipe
• It can be used when the flue system can insure that the provided gas pressure can reach the
lowest requirement. If gas water heater reach the rated heat input, the gas pressure must
reach the rated heat input in the technologic parameter form. Gas rated pressure bellows:
Natural Gas 13mbar.
• Gas inlet
(1) For LPG, use a gas rubber pipe with inner diameter 9.5mm to connect, put one end into
the gas inlet of the heater, the other into the reducer outlet of the gas tank, insert the pipe

Install a water valve before the
water inlet. (Fig. 15)
• Hot water outlet
Use a flexible or rigid pipe to conect with the sprayer without valve. If a valve or switch is
connected to the sprayer, the outlet pipe shall not use heat and pressure unendurable
material like plastics, aluminum pipes, so as to avoid the pipe break and scald user.
