WARNING Any appliance that burns natural gas, propane gas, fuel oil, or coal is capable of producing carbon monoxide (CO). Carbon Monoxide (CO) is a gas which is odorless, colorless and tasteless but is very toxic. CO is lighter than air and thus may travel throughout the building. BRIEF EXPOSURE TO HIGH CONCENTRATIONS OF CO, OR PROLONGED EXPOSURE TO LESSER AMOUNTS OF CO MAY RESULT IN CARBON MONOXIDE POISONING. EXPOSURE CAN BE FATAL AND EXPOSURE TO HIGH CONCENTRATIONS MAY RESULT

1. General Information The BIASI B 10-series boilers are wet base design, sectional, cast-iron boilers for forced hot water heating systems. The boilers are shipped pre-assembled from the factory in lengths from three to nine sections. They are designed for firing with oil or gas power burners, which are packed separately along with the jacket and controls for shipping purposes. When the boiler is received, check the contents to ensure that there is no shortage or damage to any part o

2. Boiler Block Assembly All QHT BIASI B10 Series Boilers are shipped from the factory in assembled boiler blocks. If, however, the block needs to be split into sections for ease of delivery, please read the following: To assemble split blocks, move sections into parallel and facing each other. Sections may be slid along boards placed underneath the sections. Inspect nipple ports for damage or burrs. Remove any burrs by scraping the port very lightly. Wipe the push nipples and nipple p

3. Boiler Location The following are the minimum clearance to construction or combustible materials: 9” 1. 9” from the top, sides, 24” and rear of the boiler. 9” 2. 18” from the flue pipe in any direction. 3. 24” from the front of the boiler. DANGER The boiler must be located on a non-combustible floor. A smooth, level concrete floor is recommended. Locate the boiler as close as possible to the chimney. If boiler is installed on combustible flooring, consult local authorit

4. Installation of Boiler Trim Components Cont. 1. Install L4006A aquastat in upper left or right rear tapping using 3/4” immersion well. All tapings and joints should be sealed with piping compound. The L4006A o can be adjusted up to 220 F, and should be set to the desired temperature by the installer. The differential is also adjustable between 5 and 30 degrees. It should be set as close to 30 degrees as possible to prevent short cycling of the boiler. If you are installing a 7248

5. Piping the Boiler All piping must conform to state and local codes. Page 11 shows the location and size of the boiler tappings. It is recommended to install unions and gate valves at the inlet and outlet of the boiler, so it may be readily isolated for service. For Canadian installations, a low water cut off is required if the boiler is installed above the level of radiation. Even if the boiler is installed below the level of radiation it is strongly recommended that a low water

6. Intake Venting 1. Be certain adequate air is available for combustion and ventilation. a.) Boiler located in unconfined space: Installation in large areas, such as basements, can usually be assumed to provide sufficient air. b.) Boiler located in confined space : (See Figure A.) If all air for combustion and ventilation is to come from within the building: Two (2) openings shall be provided with one (1) opening commencing within 12 inches of the ceiling and one (1) o

6. Intake Venting Cont. c.) Boiler located in a room under negative pressure: If the boiler is to be installed within a home where the operation of exhaust fans, attic fans, kitchen ventilation systems, clothes dryers or fireplaces may create severe negative vent pressures causing unsatisfactory combustion and venting, special provisions should be made for additional make-up air to supply the other air requirements. If building is of tight construction, combustion air requirements may

7. Exhaust Venting The B10 boiler is a high efficiency unit that requires proper venting. The boiler must be vented to the outdoors by means of a tile lined masonry or a approved pre-fabricated chimney of the size and height recommended by the manufacturer or by a listed "power venting" unit which provides draft by mechanical means. In many installations, particularly older interior and most exterior chimneys, a corrosion resistant liner should be installed and may be required by cod

7.1 Common Exhaust Venting Cont. 3.Insofar as practical, close all building doors and windows and all doors between the space in which the appliance remaining connected to the common venting system is located and other spaces of the building . Turn on any appliance not connected to the common vent system. Turn on all exhaust fans except for summer exhaust fans. Close the fireplace damper if applicable. 4.Place in operation the appliance being inspected. Follow the lighting instructi

8. Burner Setup Good, reliable operation with a minimum of service, starts with attention to the small details: Oil: 1. Setting the nozzle position and electrodes "by the book" using the manufacturer's gauges. 2. Installing a quality micron filter at the burner. 3. Making careful/tight flare connections, without couplings, on oil suction line. 4. Checking fuel pump pressure. 5. Checking draft at the breeching to insure it is adequate to overcome flue gas resistance. (-.02 to –.
