This Operator's Manual is a supplement to a self-instructional course prepared for the United States Environmental Protection Agency. This publication is the Boiler Room Handbook for operating and maintaining the boiler and the boiler room. As the student completes this handbook, he is putting together a manual for running his own boiler. The handbook contains correct instrument and control settings, a listing of spare parts to be kept on hand, names and model numbers of parts plus fuel oil suppliers and service contractors. A troubleshooting reference and glossary conclude this manual. (BT)
