Step 10. Now that the universal blower is properly
modified for a -10 series water heater, the
blower can be properly positioned and
secured on top of the water heater. To
place the blower on the water heater, feed
the blower from around the backside of
the water connections. Secure the
universal blower using (3) screws, P/N
239-44113-00, provided with the kit, into
the pilot holes created in Step 6. Tighten
them using a ¼” nut driver.
Step 11. Find the correct universal blower wire
harness provided with the kit, P/N
239-47193-00. Connect the wire harness
to the receptacle in the jacket head and
into the receptacles in the blower housing.
Secure (3)
blower
screws.
Plug both the blower
cord sets into the blower
receptacles.
Insert other end of wire
harness into receptacle on
jacket head.
Step 9.
a.) Ensure that the pressure switch, P/N
239-47192-02, is mounted in the
vertical position, as shown. This
pressure switch comes standard in the
blower from the factory. Its vacuum
setting should read -0.80" wc.
b.) Place the access compartment cover
back on the blower and secure with (3)
screws from Step 8a. Start the lower
screw first, and when doing so, make
sure that the hole in the pressure
switch’s bracket matches up to the
hole in the blower housing.
Verify electrical
and tubing
connections.
Mount in vertical
position using
bracket.
Secure (3)
cover
screws.
Warning: Do NOT over tighten (3) screws attaching
the blower to the water heater.
