14.4 Heat Exchanger Maintenance
The heat exchanger will remain clean unless a problem has developed
with combustion. Inspect the heat exchanger. Look for signs of
overheating at the front tubes which may indicate burner over firing or
persistently low air flows.
14.5 Gas Control Valve Maintenance
No regular maintenance is required on these devices. To change gas
control valves, See Page 38, Section 17.1.
Do not repair or disassemble on site.
Replace faulty gas valves with genuine replacement parts sold and
supplied by Combat HVAC Limited.
14.6 Flue Fan
The flue fan should not require maintenance. However, if the air
pressure switch is causing burner lockout, then remove the flue fan
from the vent box by unscrewing the screw at the outlet flange and the
flue fan mounting plate (See Page 42, Section 17.4). Ensure that the fan is
free to run and that the fan wheel is clean.
