Cleaning the Boilermate Heat Exchanger Coil

15.CLEANING THE BOILERMATE® HEAT EXCHANGER COIL

A diminished temperature difference between the boiler water entering and leaving the heat exchanger coil may indicate heat exchanger scale buildup. Water treatment equipment and proper maintenance will help to avoid this problem. To clean a scaled heat exchanger coil proceed as follows:

1.Shut off the cold water supply to the BoilerMate®.

2.Make a note of the temperature control setting on the BoilerMate®, then turn the unit off.

3.Relieve the water pressure in the tank by opening a hot water faucet. This will reduce the risk of scalding injury.

4.Remove the relief valve from the top of the BoilerMate®, taking care to avoid contact with the hot water, which may drain out of the plumbing.

5.Drain the BoilerMate® until the water within the tank is even with the top of the heat exchanger - approximately 15 gallons for 41-gallons units and 5 gallons for 26-gallon units.

Do not over-drain the tank. Improper thermostatic control could result during Step 6 and lead to damage to

the BoilerMate®.

6.Using a funnel, pour one gallon of non- toxic commercial phosphoric acid solution (commercial icemaking cleaning solution) into the water tank through the top opening. Be sure that the manufacturer’s directions and warnings are followed.

7.Set the temperature control to its highest setting and operate the unit until the control is satisfied. Note: Boiler may cycle on its high limit several times during this period. If the tank temperature setting has not been satisfied after 45 minutes of boiler operation, turn the BoilerMate® control off to stop boiler operation.

8.Allow heated solution to set in tank for 30 minutes, then drain tank completely using fitting and hose, as required.

9.Fill water tank with fresh, cold, conditioned water and drained completely at least two times or until drained water runs clear.

10.Reinstall the safety relief valve.

11.Open the cold water supply and fill the tank with water. Purge plumbing by operating all hot and cold water fixtures in the building.

12.Return the control to the setting noted in Step 2 and verify that the unit is functioning properly.

As an alternative to the above, the teat exchange may be removed from the BoilerMate® and cleaned. A new gasket must be installed whenever the heat exchanger is removed.
