SAFETY CONSIDERATIONS
Installing and servicing heating equipment can be hazardous due to gas and electrical components. Only trained and qualified personnel should
install, repair, or service heating equipment. Untrained personnel can perform basic maintenance functions such as maintaining water level. All
other operations must be performed by trained service personnel. When working on heating equipment, observe precautions in literature, on tags,
and on labels attached to or shipped with unit and other safety precautions that may apply.
Follow all safety codes. In the United States, follow all safety codes including the National Fuel Gas Code (NFGC) NFPA 54-2002/ANSI
Z223.1-2002. Wear safety glasses and work gloves. Have fire extinguisher available during start-up and adjustment procedures and service calls.
Recognize safety information. This is the safety-alert symbol
. When you see this symbol on unit or in instructions and manuals, be alert to
potential for personal injury.
Understand the signal words DANGER, WARNING, CAUTION, and NOTE. These words are used with safety-alert symbol. DANGER identifies
most serious hazards which will result in severe personal injury or death. WARNING signifies hazards which could result in personal injury or
death. CAUTION is used to identify unsafe practices which would result in minor personal injury or product and property damage. NOTE is used
to highlight suggestions which will result in enhanced installation, reliability, or operation.
INTRODUCTION
These Gas-Fired Steam Boilers are low-pressure, sectional cast iron boilers design certified by the American Gas Association (A.G.A.) for use with
natural and propane gases. They are constructed and hydrostatically tested for a maximum working pressure of 15 psi in accordance with the
American Society of Mechanical Engineers (A.S.M.E.) Boiler and Pressure Vessel Code Section IV Standards for cast iron heating boilers.
Check to be sure boiler size is correct before starting installation. See rating and capacity tables shown in Fig. 1. Also be sure new boiler is for
the type of gas being used. Check rating plate on right side of boiler.
The boiler must be supplied with correct type of gas, fresh air for combustion, and a suitable electrical supply. Boiler must also be connected to
a suitable chimney and an adequate piping system. Finally, a properly located thermostat is needed for control of heating system. If there are any
doubts as to the various requirements, check with local authorities and obtain professional help where needed. Take time to complete all the steps
for SAFE and PROPER operation of heating system.
If this boiler is installed in a building under construction, special care must be taken to insure a clean combustion air supply during the construction
process. Airborne particulates such as from drywall dust and from fiberglass insulation can clog the burner ports and cause incomplete combustion
and sooting.
These boilers are designed for use in closed heating systems where all of the steam is returned to boiler as condensate and the amount of make-up
water required is minimal. These boilers are not designed for or intended for use in open systems or process applications using 100 percent make-up
water. Damage to boiler resulting from such use shall not be covered under the warranty.
Where required by authority having jurisdiction, the installation must conform to American Society of Mechanical Engineers Safety Code for
Controls and Safety Devices for Automatically Fired Boilers, No. CSD-1.
Before installing the boiler in the United States, refer to the current edition of the NFGC. For further information, the NFGC is available from
National Fire Protection Association Inc., Batterymarch Park, Quincy, MA 02269; American Gas Association, 1515 Wilson Boulevard, Arlington,
VA 22209; or from Literature Distribution.
The installation must conform with requirements of the authority having jurisdiction, or in absence of local codes, to the NFGC.
The following steps are all necessary for proper installation and safe operation of boiler.
1. LOCATING THE BOILER
2. FRESH AIR FOR COMBUSTION
3. INSTALLATION—SYSTEM PIPING
4. CHIMNEY AND VENT PIPE CONNECTION
5. GAS SUPPLY PIPING
6. ELECTRICAL WIRING
7. CHECKING AND ADJUSTING
WARNING: To prevent fires or explosions, keep boiler area clean and free from combustible materials, gasoline, and
other flammable vapors and liquids.
WARNING: Improper installation, adjustment, alteration, service, maintenance, or use can cause carbon monoxide
poisoning, explosion, fire, electrical shock, or other conditions which may cause personal injury or property damage.
Consult a qualified installer, service agency, local gas supplier, or your distributor or branch for information or assistance.
The qualified installer or agency must use only factory-authorized and listed kits or accessories when modifying this
product. Boilers with cast iron burners are not to be converted to propane gas. Failure to follow this warning could result in
electrical shock, fire, personal injury, or death.
