GAS-FIRED WATER BOILER SERIES 2 — User’s Information Manual

Maintenance procedures (continued)

Monthly

Check vent piping

Check air piping

Check relief valve

Check condensate drain system

Check automatic air vents (if used)

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 problem.

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

1.Visually inspect the air inlet elbow to be sure it is unobstructed. Inspect 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.

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.

1.While the boiler is running, check the discharge end of the condensate drain tubing and the open top of the condensate tee at the boiler (see lower right illustration, page 11, for location of tee). Make sure no flue gas is escaping from the condensate drain tubing or tee by holding your fingers in front of the opening.

2.If you notice flue gas escaping, this indicates a dry condensate drain trap. See step 4 for procedure to fill trap. Call your qualified service technician to inspect the boiler and condensate line and refill the condensate trap if problem persists regularly.

Under some circumstances an Ultra vent system may not produce enough condensate to keep the condensate trap full of liquid. If the trap is not full, small amounts of flue products can be emitted into the boiler room through the condensate drain line or tee. Follow procedure below to fill trap.

3.Verify that the condensate drain line is unobstructed by slowly pouring water into the top of the PVC tee on the side of the boiler. The water should run out the end of the condensate drain line. If the water does not run out, call your qualified service technician to inspect the boiler and clean or replace the condensate drain line.

4.To fill condensate trap, if necessary, temporarily plug the end of the condensate drain line. Then slowly pour water into the ½ inch plastic tee on boiler right side. Pour until water fills drain line, then overflows into the boiler trap tubing. When water fills up to top of ½ inch tee, stop filling. Remove temporary plug from end of condensate drain line.

1. See illustration at right.

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.

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.
