CONDENSATE PUMP REMOVAL
17.9 CONDENSATE DRAIN PUMP
17.9.1 Refer to section 16.3. See Figures 24 & 28.
17.9.2 Disconnect the electrical connections on the electrical panel
for the Condense Pump and float switch.
17.9.3 Disconnect the condensate pipes from the “Y” connection
and from the flue outlet.
NOTE:
The condensate pump, pipes and tubes will contain water.
17.9.4 Remove the two screw holding the bracket to the front of the
cabinet.
17.9.5 Remove the screw holding the “Y” connection and remove.
17.9.6 Unclip the casing and remove the 2 screws holding the pump
to the bracket. Remove the pump and replace with new.
17.9.7 Check the inlet and outlet pipe ensuring there are no
restrictions to the flow.
17.9.6 Reconnect the condense drain pipe to the condense pump, leaving the flue outlet disconnected,
pour water into the flue pipe outlet to fill the condensate drain pipe and check for leaks. Reconnect
the pipe to the flue outlet.
IMPORTANT:
The condensing tube from the combustion tray MUST be routed so the tube forms a “S”
shape, making a “U” trap. Fit the tube behind the Condensate Trap to hold it in place.
17.9.9 Continue to refit in reverse order.
17.10 MAIN IGNITION/CONTROL PCB (ESYS Red Housing on Gas Valve)
17.10.1 Refer to section 16.3 and See Figure 29.
17.102 Unplug the connections from the top of the control and remove the ignition spark detection wires.
17.10.3 Unscrew the single retaining screw. Remove cover & unplug the multi-pin connections from the
control. Slide the housing off the gas valve electrical connections.
17.10.4 Replace with the new ignition control PCB and refit in reverser order.
