Cleaning the Tank
Check the tank interior for lime deposits.
Follow the procedure below to properly clean the tank
interior:
Spray the interior surfaces with a high pressure cold
water stream (ca. 58 –
72 psi) (Fig. 16).
You can increase the effectiveness by circulating
heated boiler water through the coil. The thermal
shock will cause the deposits to break off the smooth
surface heat exchanger. Use a wet vac to remove
the deposits from the bottom of the tank.
When large quantities of lime and deposits are found in
the tank, it is advisable to remove these using a
chemical treatment. We recommend to have the
chemical cleaning performed by a professional service
company.
8.3
Checking Anode Operation
The Magnesium anode rod is a sacrificial rod that will be
consumed during use. You must verify the status and
diameter of the anode rod at least once every two years.
In addition, we recommend to perform an annual check
of the electrical protective current.
Benefits of the current measurement are:
–
You do not need to shut down the heating system.
–
You do not need to access or remove the anode rod.
