For altitudes above 2,000 ft. ratings should bereduced at the rate of 4 _ for each 1,000ft. above sea level• Heating Capacity is based on D.O.E (Deparirnent of Energy) test procedure.
**Add 5 ½" to height for Vent Damper.
The Ratings marked "Net I=B-R Ratings" indicate the amount of remaining heat input that can be used to heat the radiation or terminal Units. The net I=B=R Ratings shown are based on an allowance of 1.15 in accordance with the factors shown on the I=B=R Standard as published by the Hydronies Institute. Selection of boiler size should be based upon "Net I=B=R Rating" being equal to or greater
than the calculated heat loss of the building. The Manufacturer should be consulted before selecting a boiler for installations having unusual piping and pickup requirements. These boilers must stand on a non-combustible floor. If installed on a combustible floor, use
Combustible Floor Base Number 42135-1 or 146-14-031 (3-6 section boilers) or 42135-2 or 146-14-032 (7-9 section boilers).
BOILERS FOR USE AT HIGH ALTITUDE This boiler is factory equipped for use at altitudes of 0-2,000 feet above sea level. For use at altitudes above sea level, the input
ratings are reduced by a change in main orifice size.
For altitudes above 2,000 feet above sea level, input ratings should be reduced at the rate of 4% for each 1,000 feet
above sea level. Consult the National Fuel Gas Code (NFPA54/ANSI Z223.1-1atest edition), or the manufacturer for correct orifice
sizing information. High altitude orifices are available from the boiler manufacturer.

CONNECTING THE VENT DAMPER AND VENT CONNECTOR
Refer to Fig. 1 flue diagram for the size and location of the vent (flue opening). Use a 28 gauge (minimum) galvanized pipe to connect to the chimney
IMPORTANT - The damper blade on the furnished vent damper has a !/2square inch hole (approximately 3/4"diame-
ter). On boilers equipped with standing pilot, the hole must
be left open. On boilers equipped with intermittent ignition,
the hole should be plugged by using the plug supplied with the vent damper.
1. Position furnished vent damper on top of flue outlet collar. Fasten damper securely to flue outlet collar with sheet
metal screws. Make sure damper blade has clearance to operate inside of diverter.
On 2 section boilers equipped with vent damper, the supplied 4-inch vent damper is equipped with a 3- to
4-inch adapter so that the 4-inch vent damper may be installed on the boiler's 3-inch flue outlet collar. Fasten
all fittings securely
As An Option
The damper may be installed in any horizontal or vertical
position, closer to the flue outlet collar preferred. Follow
the diagrams - Figures 9, 10 and 11.
2. Install the vent damper to service only the single boiler for which it is intended. The damper position indicator shall be in a visible location following installation. Locate
the damper so that it is accessible for servicing.
3. The damper must be in the open position when appliance main burners are operating.
4. The boiler is equipped with a factory wired harness that plugs into the vent damper.
5. Vent pipe must be same size as the flue outlet collar,
except 2 section boilers with vent damper as noted above.
6. Slope pipe up from boiler to chimney not less than V4"
per foot.
7. Run pipe as directly as possible with as few elbows as
possible.
8. Do not connect to fireplace flue.
9. End of vent pipe must be flush with inside face of chimney flue. Use a sealed-in thimble for the chimney connection.
10. Horizontal run should not be longer than 3/4the chimney height (HT) (Fig. 8)
The sections of vent pipe should be fastened with sheet metal
screws to make the piping rigid. Horizontal portions of the
vent system must be supported to prevent sagging. Use
stovepipe wires every 5' to support the pipe from above.
If the vent pipe must go through a crawl space, double wall vent pipe should be used. Where vent pipe passes through a combustible wall or partition, use a ventilated metal thimble. _he thimble should be 4 inches larger in diameter than the vent pipe

REMOVING EXISTING BOILER FROM
COMMON VENTING SYSTEM
When an existing boiler is removed from a common venting system, the common venting system is likely to be too large for proper venting of the appliances remaining connected
to it. 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.
1. Seal any unused openings 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 windows
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 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 dampers
4. Place in operation the appliance being inspected. Follow the lighting instructions Adjust thermostat so appliance will operate continuously.
5 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
6. After it has been determined that each appliance remain-
ing 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 conditions of use.
7 Any _mproper operation of the common venting system
should be corrected so the installation conforms with the
National Fuel Gas Code, ANSI Z223.1 -latest revision. When res_ztng 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 Part 11 in the National Fue! Gas Code, ANSI Z2231-latest revision
For boilers for connection to gas vents or chimneys,
vent installations shall be in accordance with Part 7, Venting of Equipment, of the National Fuel Gas Code, ANSI Z223.1-1atest revision and applicable provisions
of the local building codes. Vent connectors serving appliances vented by natural
draft shall not be connected into any portion of mechanical draft systems operating under positive pressure.

OPEN" switch, located on the damper controller. The thermostat will control the burner firing as before, while the damper will remain open. DO NOT turn damper open manu- ally or motor damage will result. Set switch to "AUTOMATIC
OPERATION" to close vent damper during burner off cycle.
Forfurther information,and for avent damper !roubleshooting guide, refer to the Effikal manual that was packaged with
the vent damper.
The vent damper must be inspected at least once a year by a trained, experienced service technician, The name of the person who originally installed your vent damper is shown on the installation label,

CHECK GASSUPP_
The gas pipe to your boiler must be the correct size for the length of the run and for the total Btu per hour input of all gas utilization equipment connected to it. See Fig. 12 for the proper size. Be sure your gas line complies with local
codes and gas company requirements. The boiler and its individual shutoff valve must be
disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess
of I/2psig (3.5 kPa).
The boiler must be isolated from the gas supply piping system
by closing its individual manual shutoff valve during any
pressure testing of the gas supply piping system at test pressures equal to or less than 1/zpsig (3.5 kPa).
CONNECTING THE GAS PIPING
Refer to Fig. 13 for the general layout at the boiler. It shows the basic fittings you will need. The gas line enters the boiler
from the right side. The following rules apply:
1. Use only those piping materials and joining methods listed as acceptable by the authority having jurisdiction,
or in the absence of such requirements, by the National Fuel Gas Code, ANSI Z223.1-1atest revision.
2. Use pipe joint compound suitable for LP gas on male threads only
3. Use ground joint unions.
4.Install a sediment trap upstream of gas controls.
5. Use two pLpe wrenches when making the connection to the gas valve to keep it from turning.
6. Install a manual shut-off valve in vertical pipe about 5 feet above floor.

CHECKING THE GAS PIPING
Upon completion of piping, check immediately for gas leaks Open the manual shut-off valve. Test for leaks by applying soap suds (or a liquid detergent) to each joint. Bubbles
forming indicate a leak CORRECT EVEN THE SMALLEST LEAK ATONCE
WARNING
Never use a match or open flame to test for leaks.

WARNING
TURN OFF ELECTRICAL POWER AT FUSE BOX BEFORE MAKING ANY LINE VOLTAGE CONNECTIONS.
FOLLOW LOCAL ELECTRICAL CODES.
II I
All electrical work must conform to local codes as well as the National Electrical Code, ANSI/NFPA-70, latest revision. In Canada, electrical wiring shall comply with the Canadian Electrical Codes, CSA-C22.1 and .2.
ELECTRIC POWER SUPPLY
Prior to making any line voltage connections, service switch at boiler should be in the offpnsition and the power turned offat
the fuse box.
Run a separate 120 volt circuit from a separate over current protection device in the electrical service entrance panel. This
should be a 15 ampere circuit. A ser+ice switch has been provided and should be mounted to the Junction box located on the
exterior boiler jacket. See Fig. 13-1 for diagram showing power supply connection points. The boiler, when installed, must be eleotrically grounded in accordance with the requirements of the authority having
jurisdiction or, in the absence of such requirements, with the National Electrical Code, ANSI/NFPA-70, latest revision. In
Canada, electrical wiring shall comply with the Canadian Electrical Codes, CSA-C22.1 and .2. Run a 14 gauge or heavier copper wire from the boiler to a grounded connection in the service panel or a properly driven and
electrically grounded ground rod.
INSTALL YOUR THERMOSTAT
The thermostat location has an important effect on the operation of your boiler system. BE SURE TO FOLLOW THE
INSTRUCTIONS INCLUDED WITH YOUR THERMOSTAT.
Locate the thermostat about five feet above the floor on an inside wall. It may be mounted directly on the wall or on a
vertical mounted outlet box. It should be sensing average room temperature. Avoid the Following:
DEAD SPOTS: Behind doors
Comers and alcoves
Set heat anticipator at 0.1 amps. Connect 24 volt thermostat leads to the two(2) yellow wires located in service switch
junction box, located on outer jacket of boiler. See Fig.13-1 for service switch junction box and thermostat field wiring
connections.
VENT DAMPER WIRING
The boiler is equipped with a factory wired harness with 4 pin molex plug, that plugs into a 4 pin molex receptacle inside the vent damper operator. The vent damper must be connected for the boiler to operate. Wiring diagrams follow for the various
different models.
COLD SPOTS: Concealed pipes or ducts
Stairwells - drafts Unheated rooms on
other side of wall
HOT SPOTS: Concealed pipes Lamps
Fireplace Direct sunlight
TV sets Kitchens
Radios
CAUTION
Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and
dangerous operation. Verify proper operation after servicing.
