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 ma imum heating efficiency.
We realize that it is not possible to answer all questions about the Linear series boiler in this
manual. Reading this installation manual does not make the reader an e pert in all aspects of
installation and operation, and does not replace the need for a qualified, licensed heating
contractor. We urge you to contact your installing contractor or distributor if you are in question
about any aspect of your boiler's performance. Our main concern is that you are satisfied with
your boiler and its performance. We require that your contractor complete efficiency tests
using instruments.
The controls and accessories listed in this manual are intended to serve as guidelines rather than
specific recommendations. We realize that other makes and models of such devices are
available and can be used as successfully as those we specify. The installing contractor is the
best judge of a system's specific requirements, as well as the local availability of certain makes
and models of controls and accessories. The preceding does not apply, however, to the
equipment that comes with every boiler, such as the overheat control (L4006E) and pressure
relief valve. The installation of the specific devices supplied with every boiler is absolutely
necessary to the safe operation of the boiler and protection of the heating system.
This Linear boiler has a limited warranty, a copy of which is provided with the boiler. Please
be sure to return the warranty registration card as the warranty will be void without your boiler's
serial numbers, date of installation and the name of your installer being on record in our files.
Thank you for purchasing our B-40 Linear series boiler. If you have questions or comments,
please don't hesitate to contact us immediately. Our goal is 100% customer satisfaction.

Any appliance that burns natural gas, propane gas, fuel oil, wood or coal is capable of producing
carbon mono ide (CO). Carbon Mono ide (CO) is a gas which is odorless, colorless and tasteless but
is very to ic.
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. BRIE
EXPOSURE TO HIGH CONCENTRATIONS O CO, OR PROLONGED EXPOSURE TO
LESSER AMOUNTS O CO MAY RESULT IN CARBON MONOXIDE POISONING.
EXPOSURE CAN BE ATAL AND EXPOSURE TO HIGH CONCENTRATIONS MAY
RESULT IN THE SUDDEN ONSET O SYMPTOMS INCLUDING UNCONSCIOUSNESS.
Symptoms of CO poisoning include the following:
Dizziness Vision problems Shortness of breath
Headache Loss of muscle control Unclear thinking
Nausea Weakness Unconsciousness
The symptoms of CO poisoning are often confused with those of influenza, and the highest incidence
of poisoning occurs at the onset of cold weather or during flu season. A victim may not e perience
any symptoms , only one symptom, or a few symptoms. Suspect the presence of carbon mono ide if
symptoms tend to disappear when you leave your home.
The following signs may indicate the presence of carbon mono ide:
* Hot gasses from appliance, venting system, pipes or chimney,
escaping into the living space.
* Flames coming out around the appliance.
* Yellow colored flames in the appliance.
* Stale or smelly air.
* The presence of soot or carbon in or around the appliance.
* Very high une plained humidity inside the building.
If any of the symptoms of CO occur, or if any of the signs of carbon mono ide are present, VACATE
THE PREMISES IMMEDIATELY AND CONTACT A QUALI IED HEATING SERVICE
COMPANY OR THE GAS COMPANY AND THE IRE DEPARTMENT.
To reduce the risk of CO poisoning, have your heating system "tuned up" by a licensed heating
contractor or the gas company - preferably before each heating season. Also have the service
company check your chimney or vent pipes for blockage.
The building should be adequately ventilated, particularly if you have tightly insulated your home.
ONLY QUALI IED, LICENSED SERVICE CONTRACTORS SHOULD PER ORM WORK
ON YOUR BIASI B-40 BOILER.

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. The boiler jacket, burner and controls are packed separately for
shipping.
Note: All equipment should be inspected upon delivery, and any damage or shortage should
be reported immediately.

Locate the boiler to provide sufficient clearance for inspection, servicing and maintenance.
Minimum clearance to construction or combustible materials shouldn't be less than si (6) inches from
the top, sides and rear of unit, and eighteen (18) inches from the flue pipe in any direction. Front
clearance should be at least twenty four (24) inches. When choosing a location for the boiler, take
into consideration the 12” supply manifold on the back of the boiler. Adequate space must be given to
pipe the manifold in and for the smoke pipe to clear the manifold. Greater distances for ease of access
should supersede fire protection clearances. 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 authorities for proper method of covering
floor. The boiler must not be installed on carpeting.
Caution: Do not store or use flammable materials, chemicals or flammable liquids,
especially gasoline, in the vicinity of this heating appliance.
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.
OUTSIDE AIR: When combustion air is supplied directly through an outside door or wall,
each opening shall have a free area of one square inch per 4,000 BTUH input for the total input of all
the appliances in the enclosure.
INSIDE AIR: When combustion air is supplied from inside the building, each opening shall
have a free area of one square inch per 1,000 BTUH input for the total of all appliances in the
enclosure. In no case shall the openings be less than 105 square inches each.
In both cases, check manufacturers ratings for louver net free area, and correct for screen
resistance to net free area.
If the boiler is to be installed where the operation of e haust 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 not be met and combustion air ducts from outside may be necessary. Please refer to NFPA No.
31.
Do not install the boiler until the proper combustion air has been arranged

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 installa-
tion 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. Remove any
burrs by brushing the port very lightly. Wipe the push nipples and nipple ports with a clean cloth.
Apply a film of nipple compound to both the nipple and port. Install the nipple in the port and then
seal it by hitting it with a rubber mallet. Apply section sealant to one section only and slide sections
together. If the boiler came in sections, you will want to draw the sections together 2 or three at a time
to insure that the blocks are coming together properly. Install the four draw rods and draw the sections
together evenly (measure with yardstick). The longer draw rods should be installed on the top of the
boiler. The shorter draw rods are installed on the bottom of the boiler. The bottom draw rods should
not e tend past the front section. Draw the sections together until sections make iron-to-iron contact
at a point around the top and bottom ports of each section. Check to insure that the combustion cham-
ber is sealed using a flash light or other lighting device. Place the flashlight into the combustion
chamber and look for light on the floor or surrounding walls (this is best done in a dark room). If light
appears out of the boiler use a high temperature caulk to fill in the gaps between the block sections.
DO NOT OVER TIGHTEN DRAW RODS

Good, reliable operation with a minimum of service starts with attention to the small details:
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.
6. Setting the air band properly with well maintained instruments. A good target is 11% to 12.5% of (CO
2
) or 6.5%
to 3.8% of (O
2
).
Note: Oil and Gas burners on B40-series boilers cannot be properly commissioned without instruments and gauges.
The following information applies only to the BIASI B-40 series boilers at a ma imum output
for power venters or lined chimneys only.
