WARNING
Hazardous Gases
and Flammable
Vapors!
Exposure to hazardous gases from fuel substances have been shown to cause
cancer, birth defects or other reproductive harm. Improper installation,
adjustment, alteration, service or use of this product could cause flammable
mixtures. To avoid hazardous gases and flammable vapors follow proper
installation and set up of this product and all warnings as provided in this
manual. Failure to follow all instructions could result in death or serious injury.
10. Inspect the support means to be sure that everything is firmly anchored in-
place.
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, Figure 10, 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" (for #47) and 1/16" (for #50).
