calculate the next largest size.

Maximum resistance allowed for a straight length of 28mm pipe (D2) from G 1/2 temperature & pressure valve equates to: 18m. Subtract the resistance for 4 no. 28mm elbow at 1.0m each = 4m. Therefore the maximum permitted length equates to: 14m

As the actual length is 7m, a 28mm (D2) copper pipe will be satisfactory.

2.12ELECTRICAL CONNECTION

WARNINGS

The outlet from the temperature & pressure relief valve must not be used for any other purpose. This also applies to the expansion relief valve. No other valve is to be fitted between the cold water combination valve and the cylinder.

The temperature & pressure relief valve must not be removed in any circumstances. Any of the above will totally invalidate the guarantee.

The electrical installation must be in accordance with the current I.E.E. wiring regulations.

PROTECH ELECTRONIC ANTI-CORROSION SYSTEM

The ProTech system, an exclusive solution, is an electronic anti-corrosion protection system which ensures maximum longevity of the appliance, regardless of water quality. The electronic circuit creates a difference in potential between the hot water tank and the titanium electrode, thereby guaranteeing optimum protection of the tank and preventing corrosion.

To ensure the proper operation of the protection system, IT MUST BE
