7.3.1 Cleaning the Condensate Drain Line
In order to inspect and clean the condensate line, do the following:
1. Refer to Figure 7-1, disconnect the pipe at location “A“.
2. Check that no deposits have accumulated inside the drain. If there are any deposits flush
them out with clean water.
3. Reassemble the drain in reverse order.

WARNING!
Before operating the boiler, it is absolutely necessary to verify that
the condensate P-trap is filled with water. If the boiler is operated
without the P-trap being properly filled, there is a danger of toxic
combustion gases escaping from the unfilled condensate drain
opening.
7.4 Checking CSD-1 Manifold Flow Switch
Check the function of the flow switch in the CSD-1 manifoild at the boiler hot water outlet. If it is
not functioning, check the wiring to the terminal of the BMM module labeled “FL“ or replace with
a new flow switch.
