damaged or missing insulation. Repair or replace as needed.
15. Check draft, manifold pressure, and combustion. Conduct combustion
efficiency test and adjust burner(s) for efficient safe operation. Combustion
measurements required are CO%, CO2%, O2%, stack temperature, and boiler
room temperature. No smoke or CO should be evident. Overfire draft should be at
least + 5 PA (+0.02 inches water gage (W.G.)) for oil burners. Adjust manifold
pressure as specified by the manufacturer.
16. Check expansion tank and air eliminator equipment for leaks, corrosion, etc.
Repair or replace defective equipment.
17. Inspect control equipment for proper sequence and operation. Covers on

should be firmly attached to the boiler in forced draft systems. The breaching and
stack should be properly supported and either vertical or sloped upward.
20. Check shell for cleanliness, excessive rust, corrosion streaks, deformations, and
cracks. Clean and repair as necessary. Repaint to cover bare metal. Assure
