For overall system protection, it is recommended to install a filter and sludge removal system
in the boiler return piping.
Any approved (based on application testing at burner manufacturer's facilities) oil or power gas
burner can fire into G315 boilers. Burners with low fire start or two stage firing are recommended.
The high fire setting on the burner should match the rated output of the boiler to prevent
condensation in the heat exchanger. The CO volume percent in undiluted, dry flue gas should
not exceed .04% (400 ppm).
