Dear Customer:

Thank you for buying a BIASI SG boiler.

The BIASI SG Pro is a cast iron, oil or gas fired hot water boiler, using the famous 3-pass design.

The boiler is light, compact, simple, rugged and engineered for maximum home heating efficiency.

We realize that it is not possible to answer all questions about the SG Pro-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 (Hydrolevel 3250) 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.

All SG Pro-series boilers are built in accordance with the ASME boiler and pressure vessel code,

and bear the "H" stamp. The BIASI SG Pro boiler has been tested to CSA standard 4.9.

This BIASI SG Pro boiler has a limited lifetime warranty (refer to back of manual), a copy of which

is provided with the boiler. Please be sure to return the warranty registration card or register on-

line at www.qhtinc.com/support/online-warranty-registration. The warranty will be void without your

boiler's serial numbers (located on the plate on the leg of the boiler), date of installation and the

name of your installer being on record in our files.

Thank you for purchasing our BIASI SG Pro 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 Technologies, Inc. Each piece of equipment

must be installed and used according to the recommendations of the manufacturer.

Codes and Regulations:

Installation of the boiler, burner, oil tank and related equipment must conform to

national, state and local regulating agencies and codes applicable to the installation of the

equipment. In the absence of local requirements, the following codes apply:

National Fire Protection Association (NFPA)

Battery March Park

Quincy, Massachusetts, 02269

http://www.nfpa.org

American Gas Association (AGA)

Pleasant Valley Road

Cleveland, OH 44134

http://www.aga.org

A. ANSI/NFPA - #31 Installation of Oil Burning Equipment

B. ANSI/NFPA - #70 National Electric Code

D. ANSI/NFPA - #Z223.1 National Fuel Gas Code

E. ANSI/NFPA - Domestic Gas Conversion Burner

Page 6 Biasi SG Pro Series

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. 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:

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 OR THE FIRE DEPARTMENT.

ONLY QUALIFIED, LICENSED SERVICE CONTRACTORS SHOULD PERFORM WORK ON

YOUR BIASI SG PRO SERIES BOILER.

WARNING

 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.

Biasi SG Pro Series Page 7

The BIASI SG Pro-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 seven 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 of the boiler system. With every boiler you should receive a boiler block,

jacket, trim kit and a burner (oil or gas).

The SG Pro Series packaged boilers are shipped from the factory as an assembled

boiler. If the block needs to be split into sections for ease of delivery, please order a standard

knocked down SG Pro Series boiler and request it to be split:

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 ports with

a clean cloth. Apply a film of sealing compound to both the nipple and port. Install the nipple in

the port and then seat it by hitting with a hammer cushioned with a block of wood. Apply boiler

mastic to one section only and slide sections together. Install the four draw rods and draw the

sections together evenly (measure with ruler or tape measure). Draw the sections together until

sections make iron-to-iron contact at a point around the top and bottom ports of each section.

DO NOT OVER TIGHTEN DRAW RODS

After assembly of boiler block, seal all joints with boiler gasket and remove boards. NOTE:

When cutting off excess length of draw rods, allow enough length to install boiler jacket on the

draw rods.
