NORA Oilheat Technicians Manual

This manual is not intended as a substitute for the manufacturers’ installation, operation and/or service instructions, which should always be consulted and considered the first and best reference for installing, commissioning and servicing equipment. This book describes recommended and well established practices for installing and maintaining oilburners, furnaces, boilers, water heaters, and heating oil tanks and piping. Additionally, it describes how venting and chimneys affect the equipment’s operation. However, the “correct” way of doing things may change over time due to new technologies, new research or safety issues that become better understood. Therefore, you must continue your education after reading this book, take continuing education classes and communicate with manufacturers and local authorities regarding changes. We describe building and installation codes, and we discuss manufacturers’ instructions. Of necessity, each of these is important to install equipment, but unfortunately, the relationships between them are not always synchronized, and therefore, sometimes they appear to conflict. The book relies on well established model codes. NFPA 31, Standard for the Installation of Oil Burning Equipment, is the predominant model code for oil equipment installations. Many states adopt this code and use it in their jurisdiction. Unfortunately, sometimes it takes time for a jurisdiction to adopt changes that are made to the code; they may use old editions, or may use competing model codes. Additionally, some NFPA changes may occur between editions of this book. Unless your county or state adopts these model codes, they are not “legally” required. However, they generally reflect best practices, and customers will expect that from you. And if you are sued and you have ignored best practices, you will almost certainly lose. Each state, county, or city may adopt a local building or fire code. Usually these will be based on uniform national codes (NFPA 31), but occasionally Oilheat Technician’s Manual 2008 Edition/Silver Copyright 2008 National Oilheat Research Alliance 600 Cameron Street Suite 206 Alexandria, VA 22314 www.nora-oilheat.org there will be variances or changes to suit local problems or issues. Some areas may rely on a different model code than NFPA 31, or their code may not be based on a national model. These codes are the law in the area in which you are working and you must follow them. Finally, each manufacturer provides instructions on how to install his equipment. The codes generally defer to the manufacturer, and state, but the manufacturer must be specific. For example, if the manufacturer says, “Use a draft regulator if necessary,” and the codebook says, “draft regulators are required,” then you must use a draft regulator. In describing draft regulators, NFPA says they must be used “unless the appliance design, conditions of installation, or combinations thereof preclude excessive chimney draft, or the appliance is listed for use without one.” Thus, NFPA says that a draft regulator must be used unless you can determine that the final installation will not allow excessive draft or the appliance is listed for use without the draft regulator. —Bob Hedden, Editor-in-Chief We want to express our deepest gratitude to the following people who spent untold hours checking over the material in this book for accuracy: Jerry Herron—RW Beckett Corp.
