How are the unit numbers assigned?
~ WATER HEATER ~
• Is the flow rate over 0.5 GPM? (p. 31)
• Check for the filter on cold water inlet. (p. 35)
• Check for reverse connection and cross connection.
• If you use the remote controller, is the power button
turned on? (p. 31)

motor keeps running for 35 seconds in order to re-
ignite quickly, as well as push all exhaust gas out of
the flue.

five minutes or more, the display turns off to
converse energy.

• Make sure the connection to the unit is correct.(p. 20)
