During cold starts, the temperature rise shall be limited – allow the burner to fire on low fire for some time to allow the parts to heat up slowly for maximum life.
Safety interlocks
Guarantee that all the required safety locks as described in the applicable local codes or regulations, or supplementary safety blocks requested for safe operation of the overall installation, are working properly and resulting in a positive

Purge
For safety reasons, it is required to purge the installation sufficiently long to ensure that all possible combustibles are evacu- ated 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
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.
