Pressure relief pipe work
• The pressure relief drain pipe [1] and [3] from the appliance should
be at least 15mm diameter copper pipe and run downwards to a safe
point of discharge, away from any electrical equipment or other
hazard, preferably to an external drain or soak away.
• Pipe [1] should be finished with a partial bend, near the outlet to face
the external wall (as shown) to help prevent freezing.
