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 below)
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.
– Contact your Maxon representative to answer
questions or address any problems.
