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. Reading this installation manual does not make the reader an expert 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.

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.

It is the responsibility of the installing contractor to see that all controls are correctly installed and

operating properly when the installation is completed.

Do not burn volatile garbage, gasoline, naphtha or other flammable liquids other than No. 2 fuel

oil. All flammable liquids (especially gasoline), chemicals, rags, paper, wood scraps, debris, etc.,

should be kept away from the boiler at all times. Keep the boiler area clean and free of all fire

hazards.

Please read the literature and warranties supplied by the manufacturers of the various accessory

equipment. This equipment is warranted by the respective manufacturers, not by Quincy Hydronic

BIASI B/40

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. 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 IN THE SUDDEN ONSET OF 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 experience

any symptoms , only one symptom, or a few symptoms. Suspect the presence of carbon monoxide if

symptoms tend to disappear when you leave your home.

The following signs may indicate the presence of carbon monoxide:

* 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 unexplained humidity inside the building.

If any of the symptoms of CO occur, or if any of the signs of carbon monoxide are present, VACATE

THE PREMISES IMMEDIATELY AND CONTACT A QUALIFIED HEATING SERVICE

COMPANY OR THE GAS COMPANY AND THE FIRE 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 QUALIFIED, LICENSED SERVICE CONTRACTORS SHOULD PERFORM WORK

ON YOUR BIASI B-40 BOILER.

3. Conforming to Codes and Regulations:

PAGE 7

BIASI B/40

Locate the boiler to provide sufficient clearance for inspection, servicing and maintenance.

Minimum clearance to construction or combustible materials shouldn't be less than six (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 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 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 extend 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

6. Boiler Block Assembly:

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

8. Burner Setup:

Good, reliable operation with a minimum of service starts with attention to the small details:

1. Setting the electrode and flame rod settings against manufacturer's specs to insure proper operation.

2. Installing properly sized gas piping according to BTU input required and length of gas line run.

3. Making sure there is proper manifold pressure before and after the gas valve using a calibrated manometer.

4. Checking draft at the breeching to insure it is adequate to overcome flue gas resistance.

5. Setting the air band properly with well maintained instruments. A good target is 9.5% to 10.5% of (CO

INSTALLATION OF SEDIMENT TRAP AND BURNER SUPPLY

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.

Locate a drop pipe adjacent to, but not in front of the boiler. Locate a tee in the drop pipe at the

same elevation as the gas inlet connection to the boiler. Extend the drop line with a nipple towards the

floor and cap to form a sediment trap. Install a tee handle shut off valve before the tee with sediment

trap and a union after the tee before the combination gas valve.

When installing the boiler, Use black steel pipe and malleable fittings (do not use cast iron parts) with

a suitable pipe dope which is resistant to liquefied petroleum gases.

Check piping for leaks. Always check leaks with a water and soap solution. DO NOT USE A

FLAME FOR CHECKING GAS LEAKS

The boiler and its individual shut-off valve must be disconnected from the gas supply piping

during any pressure testing of that piping at test pressures in excess of 1/2 psi.

9. Gas Line Piping

PAGE 13

BIASI B/40

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.

Caution: The gas valve should not be subjected to more than ½” PSIG. Therefore, the

burner should be isolated during high-pressure gas leak tests. The appliance and its

individual shut off valve must be disconnected from the gas supply piping system

during any pressure testing of that system at test pressures in excess of ½ psig. The

appliance must be isolated from the gas supply piping by closing its individual man-

ual shut off valve during any pressure testing of the gas supply piping system at test

pressures equal to or less than ½ psig.

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. Be sure the chimney and smoke pipe don't become

obstructed by squirrels, bird nests, soot buildup, chimney liner deterioration, etc. The "power ventor"

system should be installed on the leeward side of the building. Very specific requirements must be

met concerning clearances from combustibles and distances from doors and windows. Please consult

with manufacturer of "power ventor" for this information. In any case, the "ventor" must be installed

by a licensed burner mechanic and done in accordance with local codes. The B-40 boiler is a very low

stack temperature boiler (between 320 and 400F gross stack temp.) so caution should be used when

connecting to an outside built chimney. Should you have concern that the flue gases could condense,

then you should consider using a listed, "power venting" unit. If "power venting" is used to discharge

flue gases, then the power vent unit should be equipped with a postpurge control as well as delay-off,

timing control to prevent problems with fogging and nozzle post drip.

Note: 88% steady state efficiency is achieved when flue gas contains over 12.5% CO2 and the gross

stack temp. is below 350F.

The smoke-pipe connection from the boiler to the chimney should be as short as possible, with

a minimum number of elbows. The vent pipe must have a vertical rise of at least 1/4 inch per foot of

horizontal run. The vent pipe must be of the same diameter as the flue outlet on the boiler. The

chimney connector should have a minimum thickness of 24 gauge, corrosion resistant (galvanized)

steel, assembled with a minimum of three (3) sheet-metal screws, and sealed with high temperature

silicon at each joint. In most cases a barometric draft control isn't recommended as the B-40 is

designed to be pressure-fired. However, one may be needed if the boiler is being used in a high draft

situation.

10. Breeching and Venting:

PAGE 15

BIASI B/40

All piping must conform to state and local codes.

The supply and return manifolds for B-40 Linear boilers are 2 1/2” male NPT. Be sure to

provide unions and gate valves at the manifold inlet and outlet of the boiler, so the boiler may be

readily isolated for service.

Install the provided pressure relief valve so the discharge is piped directly to a drain, if

possible. If not, the discharge should be piped to the floor. In either case, the discharge pipe should be

of the same diameter as the outlet of the relief valve, with no valves or obstructions to impede

overflow from the boiler. The installation locations on the manifold for the Pressure Relief Valve, the

Temperature/Pressure Gauge as well the Honeywell L4006E Aquastat can be seen on the following

Install manual and/or automatic air venting devices at the high points in the system to eliminate

trapped air.

The weight of all piping should be supported by suitable hangars and floor stands, not by the

boiler.

It is recommended that the make-up water line have a backflow preventer and a pressure-

reducing valve to reduce line pressure to 10 to 15 psi installed adjacent to the boiler.

NOTE: If the heating system is to be filled with antifreeze, use only formulations expressly made for

hydronic heating systems (such as propylene glycol). Do not use automotive types of antifreeze

(ethylene glycol). Use of antifreeze will alter system output and characteristics. Consult factory rep's

for details or assistance.

Clearance for hot water pipes are 1 inch to combustibles.

11. Piping:

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 se-

curing 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.

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. Mount the panel installation

bracket (#82) onto the draw-rods on the upper front of the boiler. Install the six spacers (#86) onto the

draw-rods. Two on the upper draw rods in the front and the remaining spacers onto the draw-rods in

the back of the boiler. Install the rear insulation (#101) onto the boiler. Place the side panels (#66,52)

onto the boiler making sure the draw rod spacers are between the side panels and the boiler casting.

Tighten the sides of the casing to the panel installation bracket (#82) using sheet metal screws. Screw

two studs (#90) into the bottom front of the boiler and screw on the threaded hex spacers (#87) onto

the studs. Attach the lower mounting bracket (#83) to the boiler by using two bolts (#89) and screw-

ing them into the threaded hex spacers. Then using sheet metal screws, attach the lower mounting

bracket to the sides of the casing. Slide the control panel (#110) onto the casing from the top and se-

cure it to the control panel support (#82) using sheet metal screws. Attach the rear panels (#84,85)

using sheet metal screws. Place the top panel (#76) onto the sides of the casing and assure that the

pins on the sides are aligned with the retaining holes on the top casing panel. Finally attach the front

panel (#81) onto the casing by aligning the retaining pins with the retaining holes. Push to insure a

positive connection.

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. Wiring done in the field between devices not attached to boiler shall conform with the

temperature limitations for type T wire (63F/35C) or other specified wire as applicable when installed

in accordance to manufacturer's

instructions and wiring diagrams.

Please refer to the wiring section of this manual for instructions on wiring the supplied control

panel.

1. On/Off Switch — Turns power to control panel on and off and will disable power to the burner

assuming the panel is wired correctly.

2. Minimum Boiler Temperature Thermostat — Maintains a minimum boiler temperature be-

tween 50 degrees F and 170 degrees F.

3. Maximum Boiler Temperature Thermostat — High limit temperature setting for boiler be-

tween 50 degrees F and 205 degrees F.

4. Thermostat Test Button — This button jumps out both thermostats allowing a technician to eas-

ily start the burner for testing if there is no call for heat. Warning, with both thermostats disabled

the only high limit left will be the manual high limit.

5. Circulator Switch - Supplies power to boiler circulator or relay panel. It is not suggested to use

this switch and it is not utilized in any of the suggested wiring diagrams in this manual.

6. Boiler On/Off Signal Lamp — Signal lamp to indicate whether main power switch is turned on

or off.

7. Temperature Gauge - Temperature gauge which takes temperature reading from top front of

boiler.

8. Manual Reset High Limit - Safety high limit that is set to 214 degrees F. If the manual high

limit is tripped, use a flat head screw driver to protective cap on reset button. Then depress reset

button making sure that it stays depressed once you have removed your finger. Once the switch is

reset replace the protective cover.

9. Burner Lock Out Signal Lamp - Lamp to indicate if the burner has gone out on lockout.

Check for fouling or soot buildup in the combustion chamber at least every twelve (12)

months.

Caution: Black carbon soot in the combustion chamber can, under certain conditions, be

ignited by a spark or open flame. To prevent this unlikely occurrence, dampen the soot deposits with a

wet brush or a fine water spray before servicing or cleaning the combustion chamber. Fouling or

carbon soot buildup on the surfaces in the combustion chamber is caused by incomplete combustion,

and is a sign of combustion air and/or venting problems. As soon as any fouling is observed, the cause

of the fouling should be corrected and the combustion chamber should be cleaned as follows:

Disconnect the electrical power supply to the boiler, burner and controls. Close Fire-O-Matic thermal

shutoff valve at burner prior to servicing. Remove the front jacket panel (#9) and the loosen the two

(2) front boiler door nuts. Swing the boiler door open. Be careful not to damage the door stud threads

or the flexible oil line. Brush and vacuum combustion chamber and flue passages until all deposits are

removed. Reassemble components in reverse order, making sure any damaged gaskets are repaired or

replaced.

Other maintenance requirements are as follows: Inspect wiring and controls for damage. Insure

controls are operating correctly. Inspect oil or gas supply lines for damage, corrosion or leaks. Repair

any leaks immediately. Inspect, clean or replace oil filter as specified by manufacturer. Inspect vent

and fill pipes for any obstruction, damage or corrosion. Clean or replace as necessary. Lubricate the

burner motor if necessary during service. Finally, consult burner manual for specific burner

maintenance instructions.

14. Commissioning:

After installation of oil/gas-fired boiler, operation and performance tests shall be conducted to

make certain that the burner is operating in an acceptable manner and that all safety controls and

devices function properly. It is critical that the high limit, low water

cutoff and burner "cad cell" relay be checked for normal operation before leaving the job. Refer to the

back page of this manual to write down the System Checkout information.
