FOREWORD Detailed installation diagrams are in this manual. These diagrams will provide the installer with a reference of materials needed and a suggested method of piping. IT IS NECESSARY THAT ALL WATER AND GAS PIPING, AND THE ELECTRICAL WIRING BE INSTALLED AND CONNECTED AS SHOWN IN THE DIAGRAMS. CHECK DIAGRAMS THOROUGHLY BEFORE STARTING INSTALLATION TO AVOID POSSIBLE ERRORS AND MINIMIZE TIME AND MATERIALS COST. SEE FIGURES 1 THROUGH 5 AND TABLES 1, 2, AND 3. This design complies with the current edition of ANSI Z21.13-CSA 4.9 for Gas-Fired Low-Pressure Steam and Hot Water Boilers. MAKE SURE THE GAS ON WHICH THE BOILER WILL OPERATE IS THE SAME AS THAT SPECIFIED ON THE BOILER RATING PLATE. The boiler installation must conform to these instructions and the local code authority having jurisdiction. In the absence of local codes, the installation must comply with the latest editions of the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and the National Electrical Code, NFPA 70 or CAN/CSA B149.1, and CSA 2 C22.1. The former is available from the Canadian Standards Association, 8501 East Pleasant Valley Road, Cleveland, OH 44131, and both documents are available from the National Fire Protection Association, 1 Batterymarch Park, Quincy, MA 02269. 4 GROUNDING INSTRUCTIONS This boiler must be grounded in accordance with the National Electrical Code, NFPA 70 or the Canadian Electrical Code CSA 2 C22.1 and/or local codes. The boiler is polarity sensitive, correct wiring is imperative for proper operation. This boiler must be connected to a grounded metal, permanent wiring system, or an equipment grounding conductor must be run with the circuit conductors and connected to the equipment grounding terminal or lead on the boiler. WARNING YOUR BOILER IS NOT DESIGNED TO OPERATE WITH A BOILER INLET WATER TEMPERATURE OF LESS THAN 120°F (49°C). COLDER INLET WATER TEMPERATURE WILL RESULT IN SIGNIFICANT CONDENSATION DEVELOPING ON THE HEAT EXCHANGER. THIS SITUATION CAN CAUSE A CORROSIVE ENVIRONMENT FOR THE HEAT EXCHANGER, BURNERS AND VENTING RESULTING IN PREMATURE DAMAGE, WHICH COULD RESULT IN SERIOUS PERSONAL INJURY OR DEATH. FOR SYSTEMS THAT USE LARGE VOLUMES OF COLD WATER OR SYSTEMS UTILIZING HEAVY WATER DRAWS, CONDENSATION CAN BE PREVENTED BY USING A BYPASS LOOP. CORRECT GAS Make sure the gas on which the boiler will operate is the same as that specified on the boiler rating plate. Do not install the boiler if equipped for a different type of gas, consult your gas supplier. PRECAUTIONS IF THE UNIT IS EXPOSED TO THE FOLLOWING, DO NOT OPERATE UNTILALL CORRECTIVE STEPS HAVE BEEN MADE BY A QUALIFIED SERVICEMAN: 1. EXPOSURE TO FIRE. 2. IF DAMAGED. 3. FIRING WITHOUT WATER. 4. SOOTING. IF THE BOILER HAS BEEN EXPOSED TO FLOODING, IT MUST BE REPLACED. LIQUID PETROLEUM MODELS Boilers for propane or liquefied petroleum gas (LPG) are different from natural gas models. A natural gas boiler will not function safely on LP gas and no attempt should be made to convert a boiler from natural gas to LP gas. LP gas must be used with great caution. It is highly explosive and heavier than air. It collects first in the low areas making its odor difficult to detect at nose level. If LP gas is present or even suspected, do not attempt to find the cause yourself. Leave the building, leaving doors open to ventilate, then call your gas supplier or service agent. Keep area clear until a service call has been made. At times you may not be able to smell an LP gas leak. One cause is odor fade, which is a loss of the chemical odorant that gives LP gas its distinctive smell. Another cause can be your physical condition, such as having a cold or diminishing sense of smell with age. For these reasons, the use of a propane gas detector is recommended. IF YOU EXPERIENCE AN OUT OF GAS SITUATION, DO NOT TRY TO RELIGHTAPPLIANCES YOURSELF. Call your local service agent. Only trained LP professionals should conduct the required safety checks in accordance with industry standards. HIGH ALTITUDE INSTALLATION WARNING INSTALLATIONS ABOVE 4,500 FEET REQUIRE REPLACEMENT OF THE BURNER ORIFICES. FAILURE TO REPLACE THE ORIFICES WILL RESULT IN IMPROPER AND INEFFICIENT OPERATION OF THE APPLIANCE, PRODUCING CARBON MONOXIDE GAS IN EXCESS OF SAFE LIMITS, WHICH COULD RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
