Bryan Boilers 200, Triple-Flex 150 External FIRE-SIDE Cleaning, Suggested Maintenance Schedule

not less than four times a year, and possibly more frequently as the local water conditions may indicate. All water introduced into the boiler should be softened and should include an oxygen scavenger like sodium sulfite. This is required to remove dissolved oxygen from the water. Dissolved oxygen will cause severe boiler tube corrosion.

Draining and refilling the boiler & system

If the system is drained and then refilled, chemical treatment is essential to treat the raw water. Use only clean, softened water.

3.4EXTERNAL “FIRE-SIDE” CLEANING

Purpose

Carbon (soot) is an insulator and corrosive. The heating surfaces of a boiler must be kept free from soot accumulation to keep the boiler operating at its highest efficiency and to avoid damage from corrosion.

Soot removal

If the yearly inspection of the boiler tube surfaces reveals a build-up of soot or rust (usually due to condensation), the tubes should be thoroughly brushed. (Tube cleaning brushes are available from Bryan Steam) To inspect and, if necessary, clean the tube surfaces and flue collector, first remove the tube access panels. Examine the exterior of the tubes for evidence of soot or rust. Using a flashlight, carefully look between the tubes. There should be an unobstructed opening between all tubes, and the top surfaces of the tube must be free from soot accumulation. Also inspect the interior of the flue collector. Brush or vacuum the soot from all surfaces. Be sure to cover Triple-Flex burner with a protective cover during cleaning to prevent soot from falling onto it.

If the buildup of soot is appreciable, the flue gas venting system must be thoroughly inspected internally as well, and cleaned as necessary.

WARNING:

If soot or condensation is apparent, a boiler service technician should be consulted. The presence of soot indicates poor combustion and possibly hazardous boiler operation. Failure to do so may result in fire, explosion potential, or asphyxiation. A combustion test and burner adjustments should be undertaken at once.

3.5SUGGESTED MAINTENANCE SCHEDULE

Daily

1.Make visual inspection of gauges, monitors, and indicators and record readings in boiler log.

2.Make visual check of instrument and equipment settings against factory recommended specifications.

3.Check operation of probe type low water cutoff(s) to ensure control is functioning.

Weekly

1.Confirm boiler area is free of combustible materials and that there is nothing obstructing air openings, draft hood relief openings, etc.

2.Check combustion safety controls for flame failure and flame signal strength as specified in manufacturer's instructions located at the back of this manual.

3.Check all limit controls.

4.Check low water cutoff as described above.

Monthly

1.Check high and low gas pressure interlocks. Refer to manufacturer's instructions for correct procedure.

Annually

1.The flue gas passages and the exterior surfaces of the boiler tubes should be
