Maintenance procedures

Boiler must be serviced and maintained

 WARNING

The boiler must be inspected and started 
annually at the beginning of the heating 
season by a qualified service technician.  
In addition, the maintenance and care 
of the boiler designated on page 5 of this 
manual and explained on pages 6 through 
8 must be performed to assure maximum 
boiler efficiency and reliability.  Failure to 
service and maintain the boiler and system 
could result in equipment failure, causing 
possible severe personal injury, death, or 
substantial property damage.

 NOTICE

The following information provides 
detailed instructions for completing 
the maintenance items listed in the 
maintenance schedule on page 5.  In 
addition to this maintenance, the boiler 
must be serviced and started up at the 
beginning of each heating season by a 
qualified service technician.

Check boiler area

 WARNING

To prevent potential of severe personal 
injury, death, or substantial property 
damage, eliminate all materials discussed 
below from the boiler vicinity and the 
vicinity of the boiler combustion air inlet.  
If contaminants are found:

Remove products immediately from the 
area.  If they have been there for an 
extended period, call a qualified service 
technician to inspect the boiler for possible 
damage from acid corrosion.

If products cannot be removed, 
immediately call a qualified service 
technician to re-pipe vent and air piping 
and locate vent termination/air intake 
away from contaminated areas.

1.  Combustible/flammable materials -- Do not store 
 

combustible materials, gasoline or any other flammable 

 

vapors or liquids near the boiler.  Remove immediately if 

 found.

2.  Air contaminants -- Products containing chlorine or 
 

fluorine, if allowed to contaminate the boiler intake air, 

 

will cause acidic condensate in the boiler.  This will cause 

 

significant damage to the boiler if allowed to continue.   

 

Read the list of potential materials listed in Table 1 on 

 

page 4 of this manual.  If any of these products are in the 

 

room from which the boiler takes its combustion air, they 

 

must be removed immediately or the boiler combustion 

 

air (and vent termination) must be relocated to another 

 area.

Check pressure/temperature gauge

1.  Make sure the pressure reading on the boiler pressure/ 
 

temperature gauge does not exceed 24 psi.  Higher 

 

pressure may indicate a problem with the expansion 

 tank.

2.  Contact a qualified service technician if problem persists.

Check vent piping

1.  Visually inspect the flue gas vent piping for any signs of 
 

blockage, leakage, or deterioration of the piping.  Notify 

 

your qualified service technician at once if you find any 

 problems.

 WARNING

Failure to inspect the vent system as noted 
above and have it repaired by a qualified 
service technician can result in vent system 
failure, causing severe personal injury or 
death.

Check air piping

1.  Visually inspect the air inlet termination to be sure it is 
 

unobstructed.  Inspect the entire length of air piping to 

 

ensure piping is intact and all joints are properly sealed.

2.  Call your qualified service technician if you notice any 
 problems.

Check relief valve

1.  Inspect the boiler relief valve and the relief valve 
 

discharge pipe for signs of weeping or leakage.

2.  If the relief valve often weeps, the expansion tank may 
 

not be working properly.  Immediately contact your 

 

qualified service technician to inspect the boiler and 

 system.

Check condensate drain system

Inspect/check condensate lines and fittings

1.  Inspect the condensate drain line, condensate PVC 

fittings and condensate trap (FIG. 2-1).
