Do not bypass any of these safety interlocks, this will result in unsafe operation. • 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 tempera ture) and retighten if necessary. • Purge For safety reasons, it is required to purge the installation sufficiently long to ensure that all possible combustibles are evacuated before ignition. Refer to the applicable local codes and your specific application requirements to determine the purge time. • Pilot ignition Adjust pilot air flow and pilot gas regulator to correct set point before pilot ignition attempt.Turn adjustable orifice screw out (counter-clockwise) several turns from its fully seated position. Refine during lighting of the pilot to a yellow/blue flame and/or strongest stable flame signal. • Main burner ignition Adjust the main gas regulator at the correct set point before igniting the main burner. Ensure that the gas/air ratio valve is in the start position when lighting the main burner. After ignition of main burner, allow some time on minimum capacity to allow the burner parts to heat up slowly. • Burner adjustment Once the main flame is ignited, adjust gas pressure to the burner to have the required combustion quality. Slowly increase capacity while observing the flame and measuring flue gas quality. Do not increase capacity too fast to avoid damage to burner parts or furnace due to excessive temperature gradient. .com combustion systems for industry MAXON reserves the right to alter specifications and data without prior notice. © 2008 Copyright Maxon Corporation.

Inspection activities and frequencies shall be carried out as specified in the installation’s manual. Perform the following activities at least annually as part of a recommended preventative maintenance routine: • Inspect burner internal parts for wear and oxidation, paying special attention to the refractory of the burner block (when applicable). • Inspect associated control instruments and devices for function with particular attention to all safety permissive switches. • Perform leak tests on fuel shut off valves according to any schedule established by the authority having jurisdiction. Visual inspections Regular visual inspection of all connections (air and gas piping to the burner, bolting of the burner mounting flange and burner flame shape and aspect are essential for safe operation. Recommended spare parts Keep local stock of spark igniter. It is not recommended to keep local stock of other burner parts.
