<Maximum Flue Length Configurations>
The unit can be adjusted to accommodate longer flue runs; refer to the below table to find the
maximum flue length based on the number of elbows. Adjust the DIP switches according to the flue
condition noted in the tables below.
Note: By default, the unit has been set to the " 1 short length" condition.
- Two 90° elbows, maximum length = 1 m
(with DIP switches set at " 1 short length" condition)
- Two 90° elbows, maximum length = 11 m
(with DIP switches set at " 4 long length" condition)
[Maximum flue Length Example]
• Disconnect power to the water heater before changing the DIP switches. Failure to perform
this
step will result in a "73" code displayed on the remote controller and a cease in operation . If this
occurs, disconnect, then reconnect power to the water heater to reset the system.
Note : Please refer to page 25 for the location of the DIP switch bank.
The power must be unplugged when adjusting
the DIP switches to switch the airflow amount.
