5.3 Filling the condensate container
with water
5.2 Elevation Adjustment Above 2,000 ft
• Adjust the DIP switches as illustrated in the
table below, if this Combi Boiler is installed at an
altitude of 2,000 ft (610 m) or higher.
• Disconnect the electrical power and then adjust
the DIP switches.
Refer to page 68 for the location of the DIP switch
bank and how to change the DIP switches.
Failure to perform this step will result a “73” code
displayed on the Operation Display and a cease in
operation.
If this occurs, disconnect, then reconnect the
electrical power to the Combi Boiler to reset the
system.
Follow the procedure described below to ensure
that the condensate container is filled with water.
Fill the condensate container by pouring approx. 10
oz. (280 mL) of water into the exhaust flue on the
top of the Combi Boiler as illustrated below.
If the vent pipe has already been installed:
After installing the condensate drain pipe, make
sure that the area around the Combi Boiler is well
ventilated; open a window or a door if necessary.
Then, operate the Combi Boiler and verify that
condensate is coming out of the condensate drain
pipe.
(During normal use of the Combi Boiler, condensate
will begin to discharge from the condensate drain
pipe within 15 minutes of use. However, depending
on the season and/or installation site conditions, it
may take longer.)
NOTE
Do not change any other DIP switches.
Prior to initial start up, make sure that you fill
the condensate container with water.
This is to prevent dangerous exhaust gases from
entering the building.
Failure to fill the condensate container could
result in severe personal injury or death.
