19. Стр. 19 Once this has been done, there should be a fairly

    smooth profile between low and high positions. Ensure that the flame is visually clean throughout the modulation range at all times. Check the oil consumption. If this is not correct for the full burner rating, the oil cam must be adjusted as follows. (a) Inch the burner to low flame and note the…

20. Стр. 20 The burner should be kept clean inside and out. It

    will be more reliable, and if an oil leak occurs it will be spotted more readily. Daily Checks Cold Oil Filter(s) On residual oil burners, rotate the cleaning knob of the cold oil filter daily. The plug in the bottom of the filter housing should be removed and sludge water drained off at intervals…

21. Стр. 21 Check the operation of the air pressure switch,

    Failure of the switch to operate prevents the oil pump from starting. Flame Occurs Followed by Immediate Lockout Check the PE cell and the air regulator for correct operation. Check that the oil pressures are correct. If necessary, check and clean the preheater hot oil filter, ensure that there is…
