FULLONEYEARWARRANTYONHOTWATERANDGASSTEAMCASTIRONBOILERS

For one (1) year from the date of installation, when this boiler is installed and maintained in accordance

with our instructions. Sears will repair defects in material or workmanship in the boiler,free of charge.

LIMITED 12 YEAR WARRANTY ON STEAM CAST IRON BOILERS

After one (1}year and through twelve (12) years from the date of installation,Sears willfurnish a replacement

SEARS INSTALLATION WARRANTY

In addition to any warranty extended to you on the Sears merchandise involved,which warranty becomes effective the date the merchandise is installed,should the workmanship of any Sears arranged installation

prove faulty within one year, Sears will, upon notice from you, cause such faults to be corrected at no additional cost to you.

FOR WARRANTY SERVICE, SIMPLY CONTACT THE NEAREST SEARS STORE OR SERVICE CENTER THROUGHOUT THE UNITED STATES. This warranty gives you specific legal rights, and

you may also have other rights which vary from stateto state.

IMPORTANT

The following are the responsibilities of the user and are not

covered by the Warranty

1. Filter clearing or replacement.

2. Damage to unit or unsatisfactory operation due to improper cleaning or use of unit in corrosive atmosphere.

3. Damage to unit or unsatisfactory operation due to blown fuses or inadequate or interrupted electrical protective devices.

4. Damage to unit caused by the use of components or other accessories not compatible with the unit.

1. Read the Owner's Manual for Safe Operation carefully Failure

to follow the rules for safe operation and the instructions can cause a malfunction of the boiler and result in death, serious

bodily injury,and/or property damage.

2. Check your local codes and utility requirements before installation. The installation must be in acordance with their

directives.

3. Before servicing, allow boiler to cool. Always shut off any electricity and gas to boiler when working on it.This will prevent

any electrical shocks or burns.

4. Never test for gas leaks with an open flame. Use soap and

5. ifthe unit is removed from the place it was originally installed, this Warranty becomes void.

6. Damage to the unit caused by accident, abuse, negligence,

misuse, riot,fire, flood, or acts of God.

check all connections. This will avoid any possibility of fire or explosion.

5. Be certain your new boiler will be using the correct gas.

Overfiring will result in premature failure of the boiler sections and cause dangerous operation.

6. Never vent this boiler into an enclosed space. Always vent

to the outside. Never vent to another room or inside a building.

7. Be sure there isadequate air supply for complete combustion.

8. Followa regular service and maintenance schedule forefficient

and safe operation.

Notethatthe height(HT)is measuredfromtheventpipetothetop.

CHIMNEY SIZING

Chimneysizing, and all otheraspectsof the vent installationmustbe in accordancewith Part 7 of the NationalFuelGasCode,ANSIZ223.1

- latestrevision,andapplicableprovisionsofthelocalbuildingcodes. In Canada,follow CAN/CGAB149.1and B149.2,InstallationCodesfor

GasBurningAppliancesandEquipment.

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 V2square inch hole (approximately 3/4"diame- ter). On boilers equipped with standing pilot, the hole must

be teft 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 1/4" 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.

The thimble should be 4 inches larger in diameter than the vent p_pe.

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 ispractical, 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.
