The installer should test operate the Water Heater,
explain to the customer how to use the Water
Heater, and give the owner this manual before
leaving the installation.
Before filling the Water Heater, pipe the
recirculation system in accordance with the
plumbing diagram on page 41 and 42.
Never turn on and fire up the Water Heater unless
the system is completely filled with water.
1. Purge the air in the Water Heater and all
the water line in accordance with following
procedure.
1) Close the gas supply valve.
2) (Only with dedicated return line) Close the
“Ball Valve for Return Line”. See the detail
plumbing information for location of “Ball
Valve for Return Line” on page 42.
3) Open all fixtures on hot water supply, and
make sure that supplied water is discharging
from each fixture without air. Then close all
the fixtures.

the whole plumbing system. See the detail
plumbing information for location of “Hose
Bibb” on page 42.

water is flushing out through the three drain
plugs without air. Then close the three drain
plugs.
NOTE Drain water into a bucket to prevent
water damage.
NOTE If gurgling noise occurs or the error
code 63 appears on the Remote

remaining in the system (e.g. Cold
Water Line, Hot Water Line, Return

Without purging air, the Water Heater
can not operate properly.
