Boiler Manual And Installation Instructions for Atmospheric Venting LINEAR 6-12 SECTION BIASI B/40 PAGE 1 Please Read Instructions Carefully Save for Future Reference WARNING If the information in this manual is not followed exactly, a fire explosion may result causing property damage, personal injury or loss of life.
PAGE 2 BIASI B/40 Dear Customer: Thank you for buying a Linear commercial boiler. The Linear is a cast iron, oil or gas fired hot water boiler, using the famous 3-pass design. The boiler is simple, rugged and engineered for maximum heating efficiency. We realize that it is not possible to answer all questions about the Linear series boiler in this manual.

BIASI B/40 PAGE 4 IMPORTANT INFORMATION Please read this page carefully. ALL BOILERS MUST BE INSTALLED IN ACCORDANCE WITH NATIONAL, STATE AND LOCAL PLUMBING, HEATING AND ELECTRICAL CODES AND ORDINANCES, AS WELL AS THE REGULATIONS OF THE SERVING ELECTRICAL, WATER AND GAS UTILITIES. All systems should be designed by competent contractors, and only persons knowledgeable in the layout and installation of heating systems should attempt the installation of any boiler.
PAGE 5 BIASI B/40 WARNING Any appliance that burns natural gas, propane gas, fuel oil, wood 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. If your BIASI B-40 boiler is not working properly, or is not vented properly, dangerous levels of CO may accumulate. CO is lighter than air and thus may travel throughout the building.
BIASI B/40 PAGE 6 2. General Information: The Linear series are wet base design, sectional, cast-iron boilers for forced hot water heating systems. The Linear boilers are designed for firing with oil and deliver high efficiencies through unique design and construction. The Linear series boilers are shipped from the factory in assembled blocks and each boiler can range from 6 to 12 sections. The sections can then be disassembled before delivery to the jobsite by QHT and then field assembled.
PAGE 7 BIASI B/40 4. Combustion Air Supply: The boiler location must provide air for proper combustion and ventilation of the surrounding area. To burn efficiently, oil requires 30 CFM/GAL. In general, boiler rooms should incorporate two (2) permanent air supply openings, one commencing within 12 inches of the ceiling, and one commencing within 12 inches of the floor. These openings should freely communicate with the outdoors.
BIASI B/40 PAGE 8 6. Boiler Block Assembly: All Linear series boilers are shipped either as an assembled boiler block or a knock-down boiler block. If the block came unassembled, or if the assembled block needs to be split for installation purposes, please read the following: To assemble split blocks, move the sections into a line facing each other. Sections may be slid along boards placed underneath the sections. Inspect nipple ports for damage or burrs.

BIASI B/40 PAGE 12 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. It is advisable to run a separate gas line from the meter to the gas burner to avoid pressure drops. Consult with the National Fuel Gas Code ANSI Z223.1 for proper sizing of gas piping for various lengths and diameters.
BIASI B/40 PAGE 13 INSTALLATION OF SEDIMENT TRAP AND BURNER SUPPLY Piping should consist of: 1. A shut off valve approximately 6’ away from the unit. 2. A 1/8” plugged NPT tapping for gas pressure measurement preferably on the manual shut-off valve (as shown or anywhere between the gas valve and the shut off value). Note: The manual shut off valve and tapping are NOT part of the SU-4 Gas Burner. Please make sure you conform to local and state codes. 3. A gas union. 4. A drip pipe.
BIASI B/40 PAGE 14 10. Breeching and Venting: The B-40 Linear 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 an 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 venting . The chimney discharge opening must be located at least 24 inches above any part of the building structure within 10 feet of the chimney.
PAGE 15 BIASI B/40 10. Blocked Flue Switch: 1. Pierce a 5/8” hole into the vent pipe near the appliance outlet. Remove one of the securing nuts from the pipe of the safety switch. Tighten the other securing nut onto the pipe as far as possible. 2. Insert the threaded pipe end into the pierced hole, then install the securing nut, then install the securing nut, which was removed in step 1, and tighten securely. 3. Please consult the wiring section of this manual for the wiring of the blocked flue switch.

PAGE 17 BIASI B/40 12. Boiler Jacket Assembly: NOTE: All piping, boiler controls, gauges and valves must be installed before the jacket has been assembled on the boiler. Refer to the following page to clarify these boiler jacket assembly instructions. Insert the separate piece of insulation (# 92) on top of boiler so the entire top and sides of boiler are covered. Use plastic strapping to secure the insulation in place.
BIASI B/40 PAGE 18 13. 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 man can service the burner and controls. The electrical wiring should be routed so as not to interfere with normal servicing of the boiler.
