Slant/Fin GX - Manual (Page 6)

(7) If equipped with vent damper, which can ONLY
be installed on boilers equipped with 24 volt gas
valve:
(a) Your vent damper must be OPEN when the boiler
is operating (BURNERS ARE ON). Ask your
installer or serviceperson to show you the vent
damper position indicator, indicating the open and
closed damper positions. Inspect for proper opera-
tion monthly. If damper position indicator indicates
that the damper is closed when the boiler is oper-
ating, SHUTDOWN the boiler immediately and call
your service agency.
(b) This device must be installed and inspected annu-
ally by a qualified installer in accordance with the
Slant/Fin vent damper installation instructions. If
improperly installed, a hazardous condition such
as explosion or carbon monoxide poisoning could
result. If installed improperly, all vent damper and
boiler warranties shall be voided.
SERVICE INSPECTION
The selected service organization should make these
inspections, preferably once each year, before the cold
weather begins:
(1) Make the checks for leaks, corrosion, noise, flame,
heat and outside air supply described under User’s
Inspection.
(2) Check safety operation of the HIGH LIMIT CONTROL
(and, for steam boilers, the LOW WATER CUTOFF). If
the boiler is equipped with an intermittent pilot ignition
system and/or an automatic vent damper, check
those devices for safe and automatic operation.
(3) Check gas input rate, by clocking the gas meter.
Inspect burner flame. Clean and adjust burners and
adjust gas rate as required.
(4) Disconnect flue pipe from draft hood. Remove draft
hood and inspect boiler heating surface below. If any
soot, scale or rust is visible, clean the boiler as
described in the next section.
(5) Replace any corroded smokepipe. Repair or replace
other devices as found necessary. Check and adjust
for normal operation. Explain to the user what was
done and what to look for to prevent future problems.
CLEANING—BOILER, SMOKEPIPE,
CHIMNEY
(See figure 18). If necessary as indicated in
(4) above, the selected service organization should clean
the boiler as follows:
If you find during your inspection any unusual noise,
water leak, corroded smokepipe, abnormal water pres-
sure or flame rollout, call for service immediately.
(1) Shut off electric power and gas supply.
(2) Disconnect smokepipe and remove draft hood.
(3) Remove jacket top panel. Remove flue cover from
boiler.
(4) Remove access door and remove burners, or place
cover over burners for dirt protection.
(5) Brush down boiler flues to bare metal. Clean all
debris from bottom of boiler after brushing. Clean
burner slots, if necessary.
(6) Replace flue cover and seal with furnace cement.
Replace burners if removed. Replace access door.
(7) Inspect draft hood and smokepipe. If corroded,
replace. If soot or deposits from condensation are
found, clean out, and inspect inside of chimney for
soot or other deposits. Clean if necessary.
(8) Reconnect hood and flue pipe and fasten and seal all
joints. Turn on gas and electric power.
(9) Check boiler performance after cleaning, and adjust
as necessary.
NOTE: Condensate (water), rust, scale and soot are not
found in the boiler or smokepipe of normally operating
system. If any of these is found, eliminate the cause. The
most likely cause of condensate and corrosion or soot is
(a) restricted air supply, or (b) a faulty chimney.
Your gas boiler must be installed and serviced by a qualified service agency or
gas supplier. The lack of proper service can result in a dangerous condition.
