Maintenance

Check vent & air piping

Visually inspect the flue gas vent piping and air piping for 

any signs of blockage, leakage or deterioration of the pip-

ing. Notify your qualified service technician at once if you 

find any problem.

  Failure to inspect the vent/air system as noted 

above and have them repaired by a qualified 

service technician can result in vent system 

failure, causing severe personal injury or death.

Check the relief valve

1.  Inspect the boiler relief valve and the relief valve dis-

charge 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.

3.  For Combi Boiler Models only:

  Inspect the Domestic 

Hot Relief Valve and relief valve discharge pipe for signs 

of weeping or leakage.  If signs are present, contact your 

qualified service technician.

Check the condensate drain system

1.  Visually inspect the condensate drain tubing and the 

end of the tube. Make sure the tube is in good condition 

and that condensate can run freely.

2.  Inspect the boiler condensate trap, located under the 

boiler (see Figure 3). Make sure the ball float in the trap 

is in place and appears to be free to move. Make sure 

the trap has water in it.

3.  Contact a boiler service technician if you observe any 

problems.

Check DHW Temperatures (Combi 

Only):

1.  Check hot water temperatures at all fixtures
2.  Allow hot water to run for several minutes and ensure 

water temperatures do not exceed 120°F.  Temperatures 

above 120°F can scald.  See scald warning on page 12.

3.  The combi boiler’s 

thermostatic mixing valve

 and/or 

other installed mixing valves may need adjustment. 

Contact your qualified service technician if temperature 

adjustments are needed.

Check automatic air vents

 

(if used — au-

tomatic air vents must be used with diaghragm-
type expansion tanks only)

1.  See Figure 4.
2.  Remove the cap from any automatic air vent in the 

system and check operation by depressing valve “B” 

slightly with the tip of a screwdriver.

 

Scald hazard

 — Water from air vent may 

be very hot. Avoid contact to prevent possible 

severe personal injury.

3.  If the air vent valve appears to be working freely and 

not leaking, replace cap “A”, twisting all the way on.

4.  Loosen cap “A” one turn to allow vent to operate.
5.  Have vent replaced if it does not operate correctly.
