A. Loose brick perhaps fallen in front of burner and obstructed the flow of oil. The petticoat pipe may be loose and out of line or the dampers may have fallen shut.
61. Q. In case brick have fallen in front of burner, how can they be removed?
A. By a hook provided for that purpose. They can usually be forced out through the vent openings, but if this cannot be done, they should be thrown against the blast wall in order to get them as far as possible out of the course of the fuel feed.
62. Q. In case a petticoat pipe becomes deranged, what can be done?
A. In case it cannot be put back in proper position, it should be removed altogether. (Trips have been successfully completed in this manner.)
63. Q. Will a corroded burner mouth prevent the proper delivery of fuel to fire?
A. Yes.
64. Q. What causes the mouth of burner to corrode?
A. The asphaltum and sand contained in the oil.
65. Q. How can this be removed on the road?
