Inspect the covers to ensure that the insulation
is not damaged or missing. If it is call the Smith
Customer Service Department.

cleanout opening fl ush with the castings to insure an
air-tight seal, see Figure 6.
3. Install the cleanout cover bolts from the baffl ed side
of the cleanout cover and start the nuts, Figure 9.

15 ft lbs, 21 Nm.
6. Apply a bead of high temperature silicone caulk
around the perimeter of the cleanout cover to ensure
