WARNING
!
WARNING
Boiler shall not be connected to any
portion of mechanical draft system
operating under positive pressure.
!
• The vent pipe must slope upward from the boiler
not less than 1/4 inch for every 1 foot to the vent
terminal.
• Horizontal portions of the venting system shall be
supported rigidly every 5 feet and at elbows. No
portion of the vent pipe should have dips or sags.
Installations of boilers and venting
should be done only by a qualified expert
and in accordance with the appropriate
Utica Boiler’s Installation, Operation
and Maintenance Manual. Installing
or venting a boiler or any other gas
appliance with improper methods or
materials may result in serious injury
or death due to fire or to asphyxiation
from poisonous gases such as carbon
monoxide which is odorless and invisible.
Figure 4 Blocked Vent Safety Switch
• This boiler series is classified as a Category I
appliance and the vent installation shall be in
accordance with “Venting of Equipment” of the
National Fuel Gas Code, ANSI Z223./NFPA, or
applicable provisions of the local building codes.
• Inspect chimney to make certain it is constructed
according to National Board of Fire Underwriters.
• Attach draft hood to flue collector at rear of
boiler, (See figure 4, below), with sheet metal
screw(s) through hole(s) provided. The vent
or vent collector shall be Type B or metal pipe
having resistance to heat and corrosion not less
than that of galvanized sheet steel or aluminum
not less than 0.016 inch thick (No. 28 GA). Do not
modify draft hood.
• Connect flue pipe same as draft hood to chimney.
Bolt or screw joints together to avoid sag. Flue
pipe should not extend beyond inside wall of
chimney. Do not install manual damper in flue
pipe or reduce size of flue outlet except as
provided by the latest revision of ANSI Z223.1.
Protect combustible ceiling and walls near flue
pipe with fireproof insulation. Where two or more
appliances vent into a common flue, the area of
the common flue must be at least equal to the
area of the largest flue plus 50 percent of the
areas of each additional flue.
8
VENT SYSTEM MODIFICATION
When an existing boiler is removed from a common
venting system, the common venting system is likely
to be too large for the proper venting of the appliances
remained connected to it. If this situation occurs, the
following test procedure must be followed:
• Place in operation the appliance being inspected.
Follow the lighting instructions. Adjust thermostat
so appliance will operate continuously.
• Test for spillage at the draft hood relief opening
after 5 minutes of main burner operation. Use
the flame of a match or candle, or smoke from a
cigarette, cigar or pipe.
At the time of removal of an existing boiler, the
following steps shall be followed with each appliance
remaining connected to the common venting system
placed in operation, while the other appliances
remaining connected to the common venting system
are not in operation.
• After it has been determined that each appliance
remaining connected to the common venting
system properly vents when tested as outlined
above, return doors, windows, exhaust fans,
fireplace dampers, and any other gas burning
appliance to their previous condition of use.
• Seal any unused openings in the common venting
system.
• Visually inspect the venting system for proper
size and horizontal pitch and determine there is
no blockage or restriction, leakage, corrosion and
other deficiencies which could cause an unsafe
condition.
• Any improper operation of the common venting
system should be corrected so the installation
conforms with the latest revision of the National
Fuel Gas Code, ANSI Z223.1/NFPA 54. When resizing any portion of the common venting system,
the common venting system should be re-sized
to approach the minimum size as determined
using the appropriate tables in Chapter 13 of the
National Gas Fuel Code, ANSI Z223.1/NFPA 54.
• Insofar as is practical, close all building doors
and windows and all doors between the space in
which the appliances remaining connected to the
common venting system are located and other
spaces in the building. Turn on clothes dryers
and any appliance not connected to the common
venting system. Turn on any exhaust fans, such
as range hoods and bathroom exhausts, so they
will operate at maximum speed. Do not operate a
summer exhaust fan. Close fireplace damper.

On a call for heat:
1. The thermostat will actuate completing the circuit
between T and T.
5. In the event the flow of combustion products
through the boiler venting system becomes
blocked, a blocked vent safety switch will shut the
main burner gas off (See figure 13 below).
2. The damper will then open thus closing the end
switch completing the circuit, and ignition will
begin.
3. In the event that the boiler steam pressure

exceeds the pressure control setting, the pressure
control will interrupt the circuit to the boiler
ignition system. The power will remain off until
the steam pressure drops below the pressure
control setting.
4. In the event a low water condition occurs, an
automatic low water cut-off device will interrupt
the circuit to the ignition system until the low
water condition is satisfied, (i.e., manually restore
the water or utilize an electric water feeding
device which will automatically restore boiler
water to its normal operating level).

CONNECTING SUPPLY AND RETURN PIPING, WATER CHILLED MEDIUM
1. Boiler, when used in connection with a refrig-
eration system, must be installed so the chilled
medium is piped in parallel with the boiler with
appropriate valves to prevent the chilled medium
from entering the boiler. See figure 11.
2. When the boiler is connected to heating coils
located in air handling units where they may be
exposed to refrigerated air circulation, the boiler
piping system MUST be supplied with flow control valves or other automatic means to prevent
gravity circulation of the boiler water during the
cooling cycle.
3. A hot water boiler installed above radiation level,
or as required by Authority having jurisdiction,
must be provided with a low water cutoff device
either as a part of the boiler or at the time of
boiler installation.
4. Suggested piping for steam heating system can
be seen in figure 1 on page 6. Actual piping may
vary based on system design and local conditions.

GENERAL INSTRUCTIONS
• Before seasonal start up it is advisable to have
a competent service agency check the boiler for
soot and scale in the flues, clean the burners,
and check the gas input rate to maintain high
operating efficiency.
• On steam boilers make certain the boiler is filled
to the water line as indicated in figure 12. The
gauge cocks should be normally open. To remove
dirt from the gauge glass the petcock may be
opened to flush out the glass.
!
• During the heating season the drain valve, on the
bottom rear of the boiler, should be opened once
a month to flush out the boiler so the device will
be free to function properly. Use a pail to catch
the discharge.
!
WARNING
Discharge will be boiling hot water.
• Air vents on steam radiators and the supply main
release air from the system. If radiators do not
heat satisfactorily, make sure the air vents are
clean and operational.
• Venting system should be inspected at the start
of each heating season. Check the vent pipe from
the boiler to the chimney for signs of deterioration
by rust or sagging joints. Repair if necessary.
Remove the vent pipe at the base of the chimney
or flue and, using a mirror, check for obstruction.
• The lever of the safety valve, shown in figure 12,
on the boiler should be operated periodically to
make sure that it is functioning properly.
• Boiler flue gas passageways may be inspected
by a light and mirror. Remove the burner access
door, (figure 12). Place a trouble lamp in the flue
collector through the draft-hood relief opening.
With the mirror positioned above the burners, the
flue gas passageways can be checked for soot or
scale.
WARNING
Discharge will be boiling hot water and
steam.
• The safety valve should open before the steam
pressure exceeds the 15 lb. reading on the gauge.
If this pressure is exceeded and the safety valve
does not open, it must be replaced. If the safety
valve leaks steam when the boiler is operating
at normal pressures, it should be immediately
replaced. Corrosion can build up rapidly at the
valve seat and prevent its functioning as a safety
device.
Discharge will be boiling hot water.
• If the water in a steam boiler appears to be
dirty or oily, or the water level in the gauge
glass fluctuates considerably, the boiler should
be cleaned and skimmed (See page 21 for
instructions). A competent service person will use
approved cleaning compounds and properly clean
and flush out the boiler. He/she should also clean
or replace air vents and traps, clean flue passages
and check for proper operation of all controls and
safety devices.
• The radiator valves on a one-pipe steam system
must be either wide open or tightly shut. Do not
attempt to regulate room temperature by partially
closing the radiator valve.

CLEANING BOILER FLUE-WAYS
To Clean The Boiler Flue-ways:
1. Pilot: with main burner operating turn the
pilot gas adjusting screw clockwise
until pilot gas is turned off. See figures 8 and 9 on
page 17. Within 90 seconds the main gas control
should close, shutting off the gas to the main
burner. After checking pilot operation, relight
following lighting instructions on pages 16-17.
1. Remove the burners from the combustion
chamber by raising the burners upward from the
manifold orifices and pulling toward the front of
the boiler. To remove the burner with the pilot
burner attached, first disconnect the pilot line
tubing and thermocouple or pilot generator leads
at the main electric gas valve. Do not remove the
pilot line tubing at the pilot as the pilot burner
orifice may drop out and become damaged or
lost.
2. Pressure control - on steam boilers - remove
cover and note pressure setting. With the boiler
operating, decrease the setting. When setting
is lower than boiler pressure, the control will
open, closing the automatic main gas valve. After
checking pressure control, reset control to original
setting.
2. Disconnect the vent pipe from the draft hood.
3. Remove the draft hood. The draft hood is
attached to the flue collector at the top by sheet
metal screw(s).
4. Remove the top jacket panel. It is attached to the
3. Mechanical Low water cut-off: Operation may
checked by opening the blow-off valve located
in the lower portion of the body. This will drain
water quickly from the cut-off body and break
circuit to automatic main gas valve. Owner should
blow off this control at least once each month of
the heating season.
jacket by sheet metal screws.
5. Remove the flue collector from the boiler casting
by loosening the nuts on the “J” bolts at either
side of the flue collector.
6. Place a sheet of heavy paper or similar material
over the bottom of the combustion chamber
and brush down the flue passageways. The soot
and scale will collect on the paper and is easily
removed with the paper.
7. With the paper still in place in the combustion
chamber, clean the top of the boiler castings of
the boiler putty or silicone used to seal between
the castings and the flue collector. Make certain
chips are not lodged in the flue-ways.
8. When the cleaning process is completed, restore
the boiler components to their original position.
Use boiler putty or GE IS-808 silicone to seal
around the flue collector and castings. Make
certain the burner ends are inserted in the slots
at the back of the combustion chamber and well
down in position over the burner orifices. Follow
the lighting instructions on the boiler to put the
burners back in operation.
Check Safety Control Circuit, after burner
adjustments are made, for satisfactory operation.
!
Water will be boiling hot water.
4. Electronic Low Water Cut-off: Operation may be
checked by opening the drain valve in the back
side of the boiler. This will drain the water from
the boiler and break the electronic circuit to the
automatic gas valve.
IMPURITIES IN BOILER WATER of a steam
boiler may cause foaming and an unsteady water
line, or prevent steam generation. They may result
in objectionable odors escaping from the vents on
water boilers. This condition is caused by oil, grease,
and sediment from pipe fittings collecting within the
boiler and can be remedied only by giving the boiler a
thorough cleaning.
BOILERS CAN BE CLEANED by skimming or
blowing down.
CAUTION
CAUTION

WARNING
!
Label all wires prior to disconnection
when servicing controls. Wiring errors
can cause improper and dangerous
operation.
Verify proper operation after servicing.
21
Boiler should not be left unattended
during cleaning process.
MAINTAINING YOUR BOILER
Skimming Off Impurities
• Some of the impurities in the boiler water will
float on the water and must be skimmed off.
Checking And Adjusting The Gas Ignition
Components
• The gas input to the boiler can be adjusted by
removing the protective cap on the pressure
regulator, see figure 8 or 9 , and turning
to increase input and
screw clockwise
counterclockwise
to decrease input.
• With the boiler empty and cool, slowly begin to
add water. After water has entered boiler - never
before - turn “on” main gas burners and adjust
flame at main manual shut-off valve so that the
water being added is kept just below boiling
point. Avoid boiling and turbulence. Gradually
raise hot water level to skimming tee, see
figure 1, installed at the supply outlet piping
of the boiler being careful not to raise it above
the opening of the tee. Skim until there are no
impurities. Repeat the process if necessary.
• Natural gas manifold pressure should be set
at approximately 3.5 inches water column.
Propane gas manifold pressure should be set at
approximately 10 inches water column.
• Manifold pressure is taken at the pressure tap on
the outlet side of the gas valve, see figures 8 and
9.
• Water may be checked to make sure it is free
from oil by drawing off a sample at the skimming
tee. If the sample is reasonably free from oil, it
will not froth when boiled on stove. This test does
not indicate the amount of sediment which may
lay in the bottom of the boiler. It is therefore
necessary that the boiler be further cleaned by
“blowing down”.
• Burner orifices should be changed if the final
manifold pressure varies more than plus or
minus 0.3 inch water column from the specified
pressure.
• To check for proper flow of natural gas to
boiler divide the input rate on the rating plate
by heating value of the gas as obtained from
the local gas company. This will determine the
number of cubic feet of gas required per hour.
With all other gas appliances off, determine the
flow of gas through the meter for two minutes
and multiply by 30 to get the hourly rate. Make
minor adjustments to the gas input as described
above.
Blowing Down Boiler
• Before blowing down the boiler, fill it to the water
line. Light burners and allow five pounds of steam
pressure to build up. Run a temporary connection
from one of the drain valves to a nearby sewer.
Connect to a drain valve on the opposite end of
the boiler from feed water inlet, if possible. Shut
off the gas burners, open drain valve and blow
down the entire contents of boiler.
• Primary air adjustment is not necessary,
therefore air shutters are not furnished as
standard equipment. Air shutters can be furnished
on request when required by local codes or
conditions.
• Allow boiler to thoroughly cool and slowly refill
to water line. Repeat step 2 as many times as
required until blow off water is clear. Owner
should blow down boiler at least once each month
of the heating season.
!
• A visual check of the main burners and pilot
flames should be made at the start of the heating
season and again at mid-season.
WARNING
Water will be boiling hot water.
• The main burner flame should have a well defined
inner blue mantel with a lighter blue outer
mantel. If the flame does not appear this way,
check the burner throats and burner orifices for
lint or dust obstruction. See figure 14.
Using Cleaning Compound
• If an exceptional amount of dirt or sludge seems
to be present in the boiler, a boiler cleaning
compound made by a reputable manufacturer
may be used according to the instructions of the
manufacturer of the compound. When any type of
cleaning compound is used, care must be taken to
thoroughly flush all traces of the compound out of
the boiler.
• The pilot flame should envelop 3/8 to 1/2 inch
of the tip of the pilot sensor. See figure 15.
To adjust the pilot flame, remove the pilot
adjustment screw and turn the inner adjustment
screw clockwise to decrease or counterclockwise
to increase pilot flame. See figures 8 and 9. Be
sure to replace cover screw after adjustment to
prevent possible gas leakage.
• Following blow down allow the boiler to cool. Add
fresh water slowly. Be certain to blow enough
times as required to remove compounds from
system.
22
MAINTAINING YOUR BOILER
• The burners and pilot should be checked for
signs of corrosion, rust or scale build-up. Clean
corrosion and rust with wire brush or replace as
necessary.
Figure 13 - Gas Control Assembly
• The area around the boiler should be kept clear
and free of combustible materials, gasoline and
other flammable vapors and liquids.
• The free flow of combustion and ventilation air to
the boiler and boiler room should not be restricted
or blocked.
• It is suggested that a qualified service agency
be employed to make an annual inspection of
the boiler, vent system and low water cutoff
(including flushing of float types) and heating
system. They are experienced in making the
inspections outlined above and, in the event
repairs or corrections are necessary, can make
the proper changes for safe operation of the
boiler.
