c.Put system back into operation and view burner while cycling through full firing range. This will give a visual check for blocked burner ports. Clean burner ports as necessary using a #47 drill. Burner plates should be cleaned with a wire brush at least once a year.
2.Inspect the flame rod and ignition electrode for dirt and moisture. Wipe off if necessary. Examine for any evidence of premature arcing. If in doubt, check con- tinuity of flame rod to be sure it is not grounding out. Replace if required.
The porcelain on the ignition electrode must be intact, not cracked.
3.Replace all access panels, which have been removed, and operate the unit for a test period. Check for normal response and function of all controls.
4.Check all gas piping for possible leaks using a soap bubble solution.
5.Inspect the support means to be sure that everything is firmly anchored in place.
SECTION IX - MAXON
Inspection and Maintenance of Gas Ports
Conduct initial inspection within the first month after commissioning.Visually check the gas ports of new burner assemblies for any piping scale or debris. Use Pin Vise with drill bit to remove.
Annual inspections are normally adequate once the initial piping debris is removed.The operating conditions of the burner will determine how frequently maintenance is actually required.
Use of an electric drill motor is not suggested unless both Pin Vise and Drill (as shown) can be chucked up in a vari- speed drill unit. Use caution, because it is easy to snap the bits off in a port when using a drill motor. Removal of broken bits from the gas ports is difficult.
Alternate drill sizes which may be used are 5/64” (for #47) and 1/16” (for #50).
