2D. Maintenance of the Tankless Coil
After several years of use, the water flow
through the coil may become restricted by mineral
deposits from the water. Mild accumulations may be
removed by an acid treatment, but your servicing
company can advise on the most satisfactory method
of cleaning or whether a replacement coil is
necessary.

to boiler.
2.
Drain the complete system.
3.
Disconnect the pipe connections to the coil.
4.
Unscrew the eight retaining bolts from coil plate.
5.
Pull out coil and clean / fit replacement as
necessary.
6.
Ensure gasket makes a water tight seal.
7.
Refill & purge before returning system to
service.
