It has to be fitted to the wall using appropriate rag bolts with minimum
diameter of 8 mm. The wall with feeble charging ability must be on the
spot where the water heater shall be hanged suitably reinforced.
3.- CONNECTION TO THE WATER SUPPLY.
The water heater may be connected to a closed-circuit pressure
system which enables several points of use. For safety reasons the
supply pipe must be fitted with a return safety valve or alternatively, a
valve of the safety class that prevents the pressure in the tank from
exceeding the nominal pressure by more than 0.1 MPa. The heating of
water in the heater causes the pressure in the tank to increase to the level
set by the safety valve. As the water cannot return to the water supply
system, this can result in the dripping from the outlet of the safety valve.
The drip can be piped to the drain by installing a catching unit just below
