Operating instructions
Instructions provided by the company or individual responsible for the manufacture and/or overall installa-
tion of a complete system incorporating MAXON burners take precedence over the installation and operat-
ing instructions provided by MAXON. If any of the instructions provided by MAXON are in conflict with local
codes or regulations, please contact MAXON before initial start-up of equipment.
Read the combustion system manual carefully before initiating the start-up and adjustment procedure.
Verify that all of the equipment associated with and necessary to the safe operation of the burner system
has been installed correctly, that all pre-commissioning checks have been carried out successfully and
that all safety-related aspects of the installation are properly addressed.
Start-up
Typical ignition sequence
OXY-THERM
responsibility of the end user, according to applicable local, state and national codes. Burner ignition
should only be attempted at minimum firing rates (see capacity charts or contact MAXON) to prevent
pressure surge in the fired chamber.
Checks during and after start-up
During and after start-up, check the integrity of the system. Check all bolted connections after first firing (first time on temperature)
and retighten if necessary.
Burner adjustment and control
Oxygen-fuel burners require accurate control of both fuel and oxygen for optimum performance. Piping to individual burners
should include control valves for both oxygen and fuel. In addition, flow meters for oxygen and fuel capable of local or remote
readout are required for proper burner adjustment.
CAUTION: Oxygen should only be used with approved materials, properly cleaned pipe and equipment,
and specially designed systems. Ordinary materials can be extremely flammable in the presence of oxygen
and air enriched with oxygen.
Oxy-fuel burners cannot be set up and operated properly using only pressure requirements for adjustment. Fully metered oxygen
and fuel control systems are required for safe and optimum performance.
