Inspection and Maintenance of Gas Ports
Conduct initial inspection within the first month after
commissioning. Visually check the gas ports of the 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
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
recommended unless both pin vise and drill (see
Figure 18) can be chucked-up in a variable-speed drill unit.
Care should be given in this instance due to the nature of
drill bits and their ability to easily snap off in a port when
using a drill motor. Removal of broken bits from the gas
port is difficult.
Alternate drill sizes to be used are 5/64 in. (for #47) and
1/16 in. (for #50).
