Anode Assembly Installation
– Continued
7.
Fully tighten the 5/16-24 hex nut on the positioning screw to lock it in place. The mounting
bracket is now firmly attached to the lifting hook, ensuring that the anode blocks are
electrically connected to the unit.
8.
Position the four (4) ‘O’ rings (P/N
88019
) in the circular recesses around the threaded
holes in the anode blocks (P/N
44174
). The ‘O’ rings keep water from entering the
threaded holes, preventing them from corroding, which would shorten the anode’s life.
9.
Fasten one anode block to the mounting bracket with two (2) 1/4–20 hex head seal bolts
(P/N
54108
) and fully tighten them. Note that these are specialized bolts with built-in ‘O’
rings –
DO NOT
substitute off-the-shelf bolts of the same size
.
DO NOT over-tighten
these bolts.
10.
Repeat the previous step to attach the second anode block to the mounting bracket.
11.
Remove any hardware or debris that may have fallen on the cardboard shield installed in
step 1 and then remove the shield from the chamber.
6.
Reassembling the Heat Exchanger
Reassembling the Heat Exchanger
1.
Place the new head gasket (P/N
18532
) on top of the heat exchanger shell flange.
2.
Place the new head release gasket (P/N
18556
), upper head liner and upper head on,
aligning them with the 5/8-11 X 3-3/4” studs in the shell flange.
3.
Replace the nuts and washers on the 5/8-11 X 3-3/4” studs.
4.
Cross tighten the nuts to approximately 75 ft.-lb. torque to obtain a uniform seating, then
progressively tighten the nuts to 200 ft/lbs. minimum.
7.
Returning the Unit to Service

7.
Reinstall the unit’s front, top and side panels.
8.
Turn on the supply gas upstream to the unit.
9.
Reconnect AC power to the unit.
10.
