Maintenance procedures — MONTHLY
Perform DAILY procedures plus the
following additional procedures . . .
Check vent piping
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 qualified service technician can
result in vent system failure, causing severe personal
injury or death.
Check air piping
(DIRECT VENT installations)
1. Visually inspect the air inlet 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.
Check the 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 the condensate drain system
1. While the boiler is running, check the discharge end of the
condensate drain tubing 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 SVF
TM
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. Follow
procedure below to fill trap.
3. Verify that the condensate drain line is unobstructed by slowly
pouring water into the exhaust sampling port on near the flue
connection (piping end 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. Fill the condensate trap with fresh water, either by removing, filling
and re-installing or by pouring water into the exhaust sampling
port the flue connection (piping end of boiler).
5. Loosen any attachments to the supplied flexible drain hose.
a. Loosen the condensate trap inlet connection.
b. Remove condensate trap and flush as needed.
The condensate trap must be filled with water during
all times of boiler operation to avoid flue gas emission
from the condensate drain line. Failure to fill the trap
could result in severe personal injury or death.
Check automatic air vents
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.
