uilding.
DO NOT use this boiler if any part has
been underwater. Immediately call a
qualified service technician to inspect
the boiler and to replace any part of the
control system and any gas control
which has been underwater.
WARNING
Should overheating occur or the gas
supply fail to shut off, DO NOT turn off
or disconnect the electric supply to the
circulator pump. Instead, shut off the
gas supply at a location EXTERNAL to
the appliance.
— Installation and service must be
performed by a qualified installer,
service agency or the gas supplier.
If your boiler is purchased with or will be equipped with an automatic vent damper, make certain
that the damper is installed and wired by a qualified installer who has been certified by your local
gas utility. See Vent Dampers page 7.
Keep the boiler area clean and free of all materials that can burn.
Never close or reduce openings that supply air for the boiler combustion and for ventilation.
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.

Inspection, cleaning, repair—
Chimney, flue pipe and boiler
Your boiler and heating system will last an indefinitely
long time at full efficiency, if it is inspected regularly
and is kept in good repair and adjustment.You, the user,
should make regular inspections, and report any problems to your service agency. At regular intervals, you
should have that agency inspect the system, and clean
he boiler and make repairs and adjustments as neces-
t
sary. What you and the service agency should do are
listed below.
Contact your gas supplier for a list of qualified service
and repair agencies.
User inspection
At least once each month during the heating season
and once just before cold weather starts:
(1) Look closely at the smokepipe and draft hood (see
Figure 18, 19 & 20). Make sure pipe joints are snug
and are fastened with screws. Cement at the chimney joint should fill the joint and should not leak air.
There should be no visible signs of rust (corrosion)
or salts from water evaporation.
(2) Look at all water (or steam) piping. There should be
no leaks or signs of leaks at any pipe joints or
around the boiler. Drain valves, other valves, and
the relief valve (or steam safety valve) should not
drip or leak.
(3A) On water boilers:
The temperature and pressure gauge indicates the
pressure in the boiler at each water temperature.
For most installations, it should indicate about 12 to
15 psi pressure when temperature is about 70 to
100 degrees F, and from 15 psi to 25 psi when temperature is up to 240 degrees F. FOR YOUR SYSTEM, there is one correct pressure for each temperature
. ASK YOUR INSTALLER OR SERVICEPERSON TO EXPLAIN AND SHOW YOU. Learn what
normal pressures to look for. If pressure decreases
from nor
mal, your system is losing water
. If pres-
ure rises from normal, the relief valve will open to
s
relieve the pressure. Call your service organization
if pressures are higher or lower than normal, and if
he relief valve spills water. Repair or adjustment is
t
eeded.
n
(3B) On steam boilers:
(a) The water level in the gauge glass must be kept
constant. You must have your installer or service
organization explain to you how water is added to
maintain water level.
(b) Most boiler models are equipped with float type low
water cutoff.
You must be familiar with this LOW WATER CUT-
OFF, how it works and HOW TO BLOW IT DOWN.
Instructions are supplied with it. Ask your service
organization to e
The cutoff should be blown down three times the
first week and should be blown down weekly there-
after. Maintenance of the low water cutoff is vital in
protecting your steam boiler against breakage due
to loss of water.
If your boiler is equipped with an electronic probe
type low water cutoff, it requires periodic testing.
Ask your service agency to test this low water cutoff
twice a year.
(4) Study the labels attached to your boiler, especially
the LIGHTING AND SHUTDOWN instructions. Have
your installer or service organization show you how
to start and shut down the boiler following those
instructions. The lighting instructions on your boiler
are also reproduced, with pictures, in this manual.
(5) Stand near the boiler, look and listen. As the burners
start and shut off, there should be no unusual noise.
No fire should be visible coming out of the front
when the burners start or run.
(6) Ample air is required for your boiler to burn fuel
cleanly and safely. Check to make sure the open-
ings provided in your house are not closed and are
not obstructed. This is most important in colder
weather, when most air is needed.

(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 operation
monthly. If damper position indicator indicates that
the damper is closed when the boiler is operating,
SHUTDOWN the boiler immediately and call your
service agency.
(b) This device must be installed and inspected annually
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.
If you find during your inspection any unusual
noise, water leak, corroded smokepipe, abnormal water pressure or flame rollout, call for
service immediately.
SERVICE INSPECTION
The selected service organization should make these
inspections, pref
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 CON-
TR
OL (and, for steam boilers, the LOW WATER
CUT
OFF) and GAS VALVE. If the boiler is equipped
with an automatic vent damper, check this device for
saf
e 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.
erably once each year, before the cold
Figure 21.
CLEANING—BOILER, SMOKEPIPE,
CHIMNEY
in (4) of Service Inspection section, the selected service
organization should clean the boiler as follows:
(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 b
(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.
(See Figure 21). If necessary as indicated
urner slots, if necessary.
(5) Replace any corroded smokepipe. Repair or re-
place 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.
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.
(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) restr

ety switch and a rollout safety s
vent safety switch is located on the draft hood flue stack.
This is a manual reset control used to prevent excessive
spillage of flue gases from the draft hood. The rollout
safety switch is a single use (one time) thermal fuse to
prevent the boiler from operation if flue passages are
