f.) Verify that all electrical connections
have been modified, as previously
indicated. Also, verify that the

the tubing is not kinked.
Step 10.
a.) Ensure that the pressure switch, P/N

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 9a. 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.
Step 11. Now that the universal blower is properly
modified for a -12/-15 series water heater,
the blower can be properly positioned and
secured on top of the water heater. To

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 7. Tighten
them using a ¼” nut driver.
