Tools you will need:
- Phillips head screwdriver Size P2
- 3/8” driver
Parts you will need:
- 31255 Heater Element Hot Spring, 115v 1.5kW, Pre-1995
- 10475-BYP Heater Body
- 70108 Heater Body Retainer Gasket
- 31212 Heater Body O-Ring

Step 1. Stand the heater element up on its end and point the cord out to the left.
Step 2. Bore out the four holes on the retainer gasket with your Phillips head screwdriver. Bore out both sides of the holes.
Step 3. Put the O-ring inside the gasket and place them both on the element, making sure the gasket holes are in alignment with the element holes.
Step 4. Place a 4078 lock washer on each of the 30348 screws.
Step 5. Place the 10475-BYP heater body over the element with the two larger ports facing away from you and the small port facing toward you.
Step 6. Align the heater body holes with the element holes and push the screws into the holes. If the screws won’t go into the holes, try boring out the holes a little more with the screwdriver.
Step 7. Turn the heater on its side with the cord facing up and install a 30392 nut on each of the screws.
Step 8. Install the 30120 grounding lug in the top right screw with the lug facing the corner and tighten all the bolts.
