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.

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.
