Guidelines for Burner Adjustments of Commercial Oil

It is often convenient to use a felt pen to mark linkage setting, so as to retrace the direction and position of adjustments. 8. ADJUST FOR GAS FIRING, If the boiler is equipped for gas firing, use a similar procedure to adjust for operation on gas. However, maxi- mum C0~ readings for gas are somewhat lower than for oil. (See Figure 5, Appendix C).
