CARE AND MAINTENANCE

This section must be brought to the attention of the owner by the

installer so that the owner can make the necessary arrangements

with a qualified service agency for the periodic care and mainte-

nance of the boiler. The installer must also inform the owner that

the lack of proper care and maintenance of this boiler and any

fuel burning equipment may result in a hazardous condition.

Installer should discuss contents of the User’s Information Manu-

al (Publication B-UIM) with the owner.

A trained and qualified service technician should perform the

inspection listed in these instructions before each heating season

and at regular intervals.

I. GENERAL MAINTENANCE

A. Safety check, see page 37.

B. Vent and air intake system inspection

1. Check for obstruction, condensation, corrosion and

physical damage.

2. Check outside termination. Screen and louvers should be

free of any debris and must be cleaned as required.

3. Perform “Venting and Air intake System Regular

Inspection”, see page 17.

C. Piping

Check the following:

1. Water piping and accessories for leaks. Slightest leaks

should be corrected.

2. System to be full of water and pressure to remain stable at

correct setting on gauge.

3. Air-control system. Noise and air binding in radiation

should not occur.

4. Low water cutoff for operation (see instruction furnished

with unit).

D. Boiler Room Air Supply

Check air vents for continuous positive supply of air as

required. Air needs are greatest in cold weather if boiler

installation is non-direct vent method. Air vents must open

and free of obstruction.

WARNING: The flow of combustion and ventilating air to

the boiler should not be obstructed.

II. ANNUAL MAINTENANCE IMPORTANT:

The spark ignitor must be replaced at the beginning of

each heating season.

III. INSPECTION DURING HEATING SEASON

A. Check water pressure regularly and add water slowly to

system when needed. If much water is added, venting may be

necessary. Regular loss of water from boiler system may

indicate either a system leak, or a faulty air control system, or

a faulty automatic fill valve.

B. Check venting system. See “Venting and Air Intake System

Regular Inspection” on page 17.

C. Check condensation drain trap to be full of water. Check for

deterioration of the tubing. Check that the trap is not plugged.

D. The combustion blower does not require or have provisions

for lubrication.

E. If required, lubricate the circulator as per the manufacturer’s

instruction.

IV. CLEANING

A. Heat Exchanger: In the unlikely event of flue passage or

water passage blockage, service to remedy situation must be

performed only by an authorized Slant/FIn representative.

B. Burner: In the unlikely event of blockage or deterioration,

service to remedy situation must be performed only by an

authorized Slant/Fin representative.

WARNING:

The ceramic combustion chamber in the burner box

contains crystalline silica.

Wear proper dust mask and gloves when servicing

combustion chamber or burners.

Crystalline Silica has been identified as carcinogenic or

possibly carcinogenic to humans.

IF REPLACEMENT PARTS ARE NEEDED

When parts are needed, refer to boiler model and serial number

shown on the boiler name/rating plate. Refer to publication

number B-10PL replacement parts for part numbers. Whenever

possible refer to the original order by number and date.

Control identification and replacement should not be attempted

by unskilled personnel. Only, simple easily - identified controls

and parts may be obtained locally. All other control and parts

should be identified by and ordered form Slant./Fin. Relief/Safety

valves must be ASME rated for the pressure and gross output of

the boiler.

For replacement parts, heating contractors should contact their

Slant/Fin boiler distributor.
