MAINTENANCE
REMOVING THE COMBUSTION ASSEMBLY
This is not a regular maintenance item, but if the heat exchanger tubes contain
carbon deposits, soot, or other residue, clean as follows:
1. Follow the shutdown procedure on Page 60.
2. Remove shroud.
3. Disconnect wiring to blowers, flame sensors, gas valves, and ignition
controllers. Remove sealed combustion tube, pressure equalization tube,
primary gas line and enhanced spark ignition gas supply line.
4. Remove the four burner assembly nuts from each assembly and pull the
entire valve, blower, and burner assembly out.
5. Perform maintenance as required.
6. Reinstall the combustion assembly with the new gasket.
7. Reconnect all electrical wiring, intake venting, pressure switches, and gas
supply lines.
Note: To ease reassembly, disconnect components from one burner
assembly at a time, and clean each individually.
MAINTENANCE FREQUENCY
Under normal use conditions, the burner(s) should not need cleaning for a
minimum of five years. However, depending on the operating environment,
the burner(s) may require periodic cleaning to remove accumulated materials.
Failure to clean burners can result in reduced unit capacity. Use sealed
combustion in dirty environments. See burner maintenance instructions
on page 69.
Note:
Soot and carbon deposits may indicate a
combustion problem that needs to be corrected.
Consult the factory.
