1. Ensure all items listed in Section 1.1 are complete.
2. Water heaters listed in Section 1.2 with date codes
FD984 and later are equipped with screw holes for the
pipe cover. The FD code is the first 3 numbers in the
appliance’s serial number (see Fig.2, pos. A). For all
earlier models, use the bottom panel of the pipe cover
as a template to drill four ⁹⁄₆₄"diameter holes into the
bottom of the water heater. (See Fig. 3).

3. For heaters without pre-drilled holes, place the water
heater on its back with the front cover removed. Position
bottom panel of pipe cover over the bottom of the water
heater being sure to line up flush where indicated (See
Fig. 4). Once aligned, mark the four holes in the bottom
panel for drilling. Remove bottom panel and drill four
⁹⁄₆₄"diameter holes into the bottom of the water heater.
