Vent Installation
! WARNING
All installations of boilers and venting should be done only by a qualified expert and in accordance
with the appropriate 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 with is odorless and invisible.
! WARNING
This boiler shall not be connected to any portion of a mechanical draft system operating under
positive pressure.
5. Connect flue pipe from draft hood to chimney. Bolt or
screw joints together to avoid sags. 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 ANSIZ223.1.
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 area of each additional flue.
1. The vent pipe must slope upward from the boiler not less
then ¼ inch for every 1 foot to the vent terminal.
2. Horizontal portions of the venting system shall be supported rigidly every 5 feet and at the elbows. No portion of
the vent pipe should have any dips or sags.
3. This boiler series is classified as a Category 1 and the
vent installation shall be in accordance with latest revision
of the National Fuel Gas Code noted above or applicable
provisions of the local building codes.
4. Inspect chimney to make certain it is constructed according to NFPA 211. The vent or vent connector 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).
Vent System Modification
When an existing boiler is removed from a common venting system, the system is likely to be too large for the proper
venting of the appliances still connected to it. If this situation
occurs, the following test procedure must be followed:
REMOVAL OF BOILER FROM VENTING SYSTEM
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.
4.
1. Seal an unused opening in the common venting system.
2. 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.
3. Insofar as is practical, close all building doors and win-

dows and all doors between the space in which the
appliances remaining connected to the common venting
system are located and other spaces of the building. Turn
on clothes dryers and any other appliance not connected
to the common venting system. Turn on any exhaust fans,
such as range hoods and bathroom exhausts, so they
operate at maximum speed. Do not operate a summer
exhaust fan. Close fireplace dampers.
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.
After it has been determined that each appliance remaining connected to a common venting system properly
vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other gas
burning appliances to their previous condition of use.
Any improper operation of the common venting system
VENT SYSTEM MODIFICATION
should be corrected so the installation conforms with
the latest revision of the National Fuel Gas Code, ANSI
Z223.1. When resizing any portion of the common venting
system, the common venting system should be resized to
approach the minimum size as determined using the appropriate tables in the latest revision of the National Fuel
Gas Code, ANSI Z223.

Normal Sequence of Operation
Figure #17
On a call for heat, the thermostat will actuate,
completing the circuit to the control. The completed
circuit to the control will first activate the circulator
and damper which will close an end switch inside
the damper. This action will complete the circuit to
the ignition system and ignition will take place.
In the event the boiler water temperature exceeds
the high limit setting on the boiler mounted high
limit control, power will be interrupted between the
control system and the ignition system. The power
will remain off until the boiler water temperature
drops below the high limit setting. The circulator
will continue to operate under this condition until
the thermostat is satisfied.
In the event the flow of combustion products through
the boiler venting system becomes blocked, the
blocked vent safety switch will shut the main burner
gas off. Similarly, if the boiler flueway becomes
blocked, a flame rollout safety switch will shut the
main burner gas off. (Figure #17) If either of these
conditions occur, do not attempt to place
the boiler back into operation. Contact a certified service agency.

and make certain the vent is in good working order.
Before seasonal start-up, have a certified 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.
!
The boiler flue gas passageways may be inspected by a light
and mirror. Remove the burner door. (Figure #20) Place a
trouble lamp in the flue collector through the draft relief opening. With the mirror positioned above the burners, the flue gas
passageways can be checked for soot or scale.
CAUTION
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation.
The following procedure should be followed to clean the flue
gas passageways:
1. Remove the burners from the combustion chamber by
raising the burners up from the manifold orifices and pulling toward the front of the boiler. (Figure #20)
2. Disconnect the vent pipe from the draft hood.
3. Remove the top jacket panel.
4. Remove the combination flue collector and draft hood
from the boiler castings by loosening the nuts on the hold
down bolts located on each side of the collector. (Figure
#17)
5. Place a sheet of heavy paper or similar material over the
bottom of the base and brush down the flue passageways. The soot and scale will collect on the paper and is
easily removed with the paper.
Verify proper operation after service.
The service agency or owner should make certain the system
is filled with water to minimum pressure and open air vents, if
used, to expel any air that may have accumulated in the system. Check the entire piping system and, if any leaks appear,
have them repaired.
Circulators need to be checked and maintained. Refer
to the circulator manufacturer's instructions.
The 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 vent for obstruction
18
General Instructions
6. With the paper still in place in the base, clean the top of
the boiler castings of the boiler putty or silicone used to
seal between the castings and flue collector. Make certain
that chips are not lodged in the flue passageways.
When the cleaning process is complete, restore the boiler
components to their original position. Use IS-808 GE silicone
(available from a distributor) to seal around the flue collector
and boiler castings.
Figure #21
3/8” TO 1/2”
IN FLAME
IGNITION ELECTRODE
A visual check of the main burner and pilot flames should be
made at the start of the heating season and again in midseason. The main burner flame should have a well defined
inner blue mantel with a lighter blue outer mantel. Check the
burner throats and burner orifices for lint or dust obstruction.
(Figures #19 and #20)
Figure #19
To adjust the pilot flame, remove the pilot adjustment cover
screw (Figures #14 - #16 on previous pages) and turn the
inner adjustment screw counterclockwise
to increase
or clockwise
to decrease pilot flame. Be sure to replace
cover screw after adjustment to prevent possible gas leakage.
The burners and pilot should be checked for signs of corrosion, rust or scale buildup. The area around the boiler must
be kept clear and free of combustible materials, gasoline and
other flammable vapors and liquids.
Figure #20
The free flow of combustion and ventilating air to the boiler
and boiler room must not be restricted or blocked.
It is recommended that a qualified service agency be employed to make an annual inspection of the boiler and heating system. They are experienced in making the inspections
outlined above, and, in the event repairs or corrections are
necessary, trained technicians can make the proper changes
for safe operation of the boiler.

Checking Gas Input Rate To Boiler
Gas input to the boiler can be adjusted by removing the
protective cap on the pressure regulator (Figures #14-#16)
and turning the screw clockwise
to increase input and
counterclockwise
to decrease input. The manifold
pressures are taken at the outlet side of the gas valve.
(Figure #15 and #16) To check for proper flow of natural
gas to the boiler, divide the input rate shown on the rating
plate by the heating value of the gas 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.

Burner orifices should be changed if the final manifold
pressure varies more than plus or minus 0.3 inches water
column from the specified pressure.
Primary air adjustment is not necessary, therefore air
shutters are not furnished as standard equipment. Air
shutters can be furnished on request where required by
local codes or conditions.
GAS VALVE
Check Safety Control Circuit after burner
adjustments are made for satisfactory operation.
1. Pilot: With main burner operating, turn the pilot
gas adjusting screw clockwise
until pilot gas
is turned off. (Figures #14-#16 on previous pages)
Within 90 seconds the main gas control should close,
shutting off the gas to the main burner.
2. High Limit Control (Figure #22): Remove cover and
note temperature setting. Decrease this setting to
minimum and operate boiler. When the boiler water
temperature exceeds the control temperature setting,
the control will open the circuit, closing the automatic
main gas valve.
