    Homeowner Information for Gas TO START UP THE APPLIANCE 1. STOP! Read the safety information on the side of the boiler. DO NOT START THE BOILER UNLESS ALL CLEANOUT DOORS ARE SECURED AND SEALED. (Skip to step 9 for oil burning boilers) 2.

  • Page 7: General Information 1

    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.

    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.

    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 can be adjusted up to 220 F, and should be set to the desired temperature by the installer.

  • Page 12

    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.

    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) opening commencing within 12 inches of...

    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.

  • Page 15: Exhaust Venting 7

    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"...

    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.

  • Page 17

    7.3 Gas Venting For boilers connected to gas vents or chimneys, vent installations shall be in accordance with part 7, Venting of Equipment, of the National Fuel Gas Code, ANSI Z223.1 or Section 7, Venting Systems and Air Supply for Appliances, of the CAN/ CGA B149, Installation Codes, or applicable provisions of the local building codes.

  • Page 21: Gas Line Piping 9

    9. Gas Line Piping Gas supply piping is to be sized and installed properly in order to provide a supply of gas sufficient to meet the maximum demand without undue loss of pressure between the meter and the boiler. Consult with the National Fuel Gas Code ANSI Z223.1 for proper sizing of gas piping for various lengths and diameters.

    10. Boiler Jacket Assembly NOTE: All piping, boiler controls, gauges and valves should be installed before the jacket is assembled on the boiler. Below is an explosion view of the boiler and jacket assembly to clarify these boiler jacket assembly instructions. Insert the separate (loose) piece of insulation on top of boiler with the foil side facing in so the entire top, bottom and sides of boiler are covered.

  • Page 23

    11. Wiring The electricity to the boiler shall come from a dedicated breaker in the electric service box. A service switch should be mounted on the side of the boiler so the burner technician can service the burner and controls. The electrical wiring should be routed so as not to interfere with normal servicing of the boiler.
