8.3.1 Cleaning the Condensate Drain Line
In order to inspect and clean the condensate line, do the following:
1. Refer to Figure 8-1, 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.

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.
8.4 Checking CSD-1 Manifold Flow Switch
Check the function of the flow switch in the CSD-1 manifold at the boiler hot water outlet. If it is
not functioning, check the wiring to terminals FL and 10 on the Input/Output box, or replace with
a new flow switch.
