3. Remove the lead wires from the heating element and check the element resistance using a VOM.
A. If resistance readings are not correct, replace heating element.
1) To replace an element, drain water from boiler shell.
2) Remove cover of contactor box, remove electric wires to that element's terminals, remove bolts
through flange of element and pull element forward.
NOTE:
When replacing an element, always use a new gasket and ensure that the flange and tube surfaces which
contact the gasket are clean. If removed element shows a pronounced scale build-up on its heating tubes, the
other elements should be removed and mechanically cleaned to remove the scale. This will prolong their life. DO
NOT immerse elements in a chemical solution to descale.
4. After new element is installed, check unit for proper operation.
