In addition to the recommended monthly service: 
1.  Clean burner of any accumulated dust or lint.  See 
Section 5.2 on "Cleaning the Burner." 
2.  Inspect burner for any signs of deterioration or 
corrosion.  Replace immediately if deterioration or 
corrosion is evident. 
Installation and service must be performed by a 
qualified installer or service agency who has been 
trained on the Patterson-Kelley MACH boiler. 
The blower motor is permanently lubricated and does 
not require periodic lubrication. 
 
5.1.5  Annually 
In addition to the recommended monthly service: 
1.  Inspect and clean the inlet screen of any 
accumulated dust or lint.    
2.  Check burner and clean off any soot or foreign 
material that may have accumulated.  See Section 
5.2 on "Cleaning the Burner."  Check for corrosion 
of the burner and its parts. If there is evidence of 
deterioration or corrosion, replace immediately. 
3.  Inspect combustion chamber when the burner is 
removed for inspection.  Note any signs of 
deterioration.  Clean as necessary. 
4.  Inspect and clean heat exchanger.  Use vacuum to 
remove accumulations from the heat exchanger 
pins and surfaces.  Clean the casting pins by 
flushing with clean water and air drying.  Do not 
use any cleaning agents or solvents.  A soft nylon 
brush may be used in accessible areas.   
5.  Drain and flush the inside of the heat exchanger as 
required (separate from system flush). 
6.  Examine the venting system at least once a year.  
Refer to the vent manufacturer's instructions for 
requirements in addition to those listed below. 
a.  Check all joints and pipe connections for 
tightness. 
b.  Check pipe for corrosion or deterioration.  If 
any piping needs replacing, do so 
immediately. 
7.  Qualified service personnel should thoroughly 
inspect the heating system and correct any 
problems prior to re-starting the boiler.   
8.  Perform combustion analysis and readjust to 
manufacturer's specifications as necessary.  It is 
recommended that a copy of this report is filed for 
future reference. 
9.  Perform a leak test of the gas valves in accordance 
with the manufacturer's instructions.   
 
Installation and service must be performed by a 
qualified installer or service agency who has been 
trained on the Patterson-Kelley MACH boiler.
