sensors from all components that are attached to
the inlet/outlet header.
4. Isolate the heat exchanger from the water supply.
5. Disconnect the header flanges from the inlet and
outlet.
6. Allow the heat exchanger to drain. Remove the
venting and remove the top, by removing the
screws that attach the top to the side panels.
Remove the side panels.
7. Remove the heat exchanger from the unit.
NOTE:
Heat exchangers are heavy and may
require two people to remove to avoid personal
injury.
8. Clean the heat exchanger: A light accumulation
of soot or corrosion on the outside of the heat
exchanger can be easily removed. Use a wire
brush to remove loose soot and scale from the
heat exchanger.
9.
NOTE:
While the heat exchanger is out of the
unit, inspect the firewall refractory insulation.
Replace if necessary.
10. Inspect the inside of the copper tubes for scale
buildup. Scale can build up on the inner surface
of the heat exchanger tubes, which can restrict
water flow. If the tubes show signs of scaling,
clean the internal surface.
11. Reassemble in the reverse order, and check
appliance operation after start-up.
NOTE: The warranty does not cover damage due to
lack of maintenance, lack of water flow, inadequate
water temperature, or improper operating practices
outlined in this manual.
