Poisoning and explosion risk due to inappropriate gas plumbing materials using and installation
is not made in accordance with the rules.

Fire protected gas valve must be used in the system, if not, risk of explosion in case of firing.

Gas connections must be done according to standards and directives.

Perform the gas leakage test, when the check valve is OFF. Gas valves can be exposure max. 150 mbar

pressure. Gas valves and burners may damaged over this pressure and as a result of explosion and

poisoning. In the pressure test of gas side, ball valve in gas device must be closed (OFF position).

Please be careful of gas type that using in the boiler and please consider on the conversion instructions.

Electrical Connections

Electrical connections must be done by authorized technicians.

Terminal box, fuse, switches and sensors delivered completely assembled and functionally tested.
