4. Carefully guide the two open ends of the heating element through the original
holes of the insulated furnace wall inside the chamber. Make sure to apply
equal pressure on each leg.
5. Check to make sure that the U (hot section) of each element is located
approximately 1/2 inch from the inside surface of each side chamber wall.
To adjust a heating element:
a. Hold the terminal end of the element
b. Apply even pressure on each terminal leg to push the element through the
holes in the insulation.
6. Use the interconnecting braided straps and the M clamps to connect the
heating elements in series (refer to
Figure “Heating Unit Replacement”
a. Fit a braided strap over the outside circumference of the heating element
terminal lead section. The strap may require some hand forming for good
contact between the terminal and the strap.
b. Squeeze the clamp jaws, opening the M clamp wings, slip the jaws over the
strap and terminal, and release the clamp wings.
7. If there are additional heating elements to replace. repeat the above steps until
all heating elements are installed and connected to element terminals.
8. Replace the side access panel.
9. Tighten the three side access panel screws located on the back of the furnace.
10.Replace the side access panel screws located on the side access panel.
Molybdenum disilicide healing elements are extremely fragile and
must be handled only with the greatest of care.
Do not rotate the clamp and strap around the terminal. This
induced rotational stress may break the heating element.
