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.

WARNING:
Risk of scalding!
Injury if discharge pipe is not routed correctly.
▶ The pressure relief valve is a safety device for the
appliance and if activated may discharge boiling
water or steam through the relief valve drain pipe.
▶ Care should be taken when siting the outlet pipe so
that it does not cause an obstruction or discharge
above a window, entrance or other public access
where it could cause a hazard.
