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 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 muscl e 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, pi pes or chim ney ,
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 humidit y 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 OR 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.

Your home should also be adequately ventilated, particularly if you have insulated your home.

ONLY QUALIFIED, LICENSED SERVICE CONTRACTORS SHOULD PERFORM WORK ON
YOUR B-10 OR SG BOILER.

1. General Information

The QHT Direct Vent components have been designed and packaged so that the Biasi
B-10 and SG boilers can be directly vented to the outside. Properly maintained, these boiler
systems are unsurpassed in efficiency and will provide years of trouble-free operation.
In addition to the standard Biasi boiler package, the Direct Vent Package is supplied
with a kit containing the standard make-up air and appropriate exhaust system piping and
hoods for your application. The last piece of the complete package is a direct vent specific
burner.
The Direct Vent Systems are a non-powered positive pressure vent hood system for
gas or oil fired appliances that provides an outlet for exhaust gases and an intake for
combustion air. The hood is designed to direct the hot exhaust gases away from the structure
without the aid of a motorized fan. All of the internal parts in contact with the flue gases are
made from corrosion resistant stainless steel.

NOTICE:

All equipment should be inspected upon delivery, and any
damage or shortage should be reported to the supplier and
shipper immediately.

2.1 Exhaust Pipe System

The B10/SG Direct Vent Systems must be installed where provisions do not exist for the ducting of

combustion by products to the outside. The direct vent connector shall not pass through any floor or ceiling.
The burner exhaust must be ducted directly to the vent hood through listed exhaust pipes provided. The exhaust
pipe throughout it's entire length must be readily accessible for inspection, cleaning and replacement.

The venting system should be installed and supported in accordance with the Nation a l Fuel Gas Code, ANSI

Z223.1, CAN/CGA B149 or in accordance with any local codes.

The Exhaust Kit consists of:

Installation of DVH Exhaust:

1. Begin by locating a suitable location for the exhaust to breech the wall. This location should be at least 12”

2. Once the hood location has been determined, cut a 7 1/2” hole through the wall for the vent terminal. Using

3. Once the hood is secure, mock up the rest of the vent kit. First put the stainless steel elbow on the hood, then

4. Once you are satisfied with the fit of the exhaust, seal each joint inside and out with high temperature silicone.

5. When installation is complete, inspect each joint and apply more sealant to any possible leaks.

1 - 6” to 5” Z-Vent Reducer 1 - 5” x 8’ Length of stainless flex pipe
1 - 5” 90 degree elbow 1 - 5” Concentric exhaust

above ground level or the expected snow level, and on the leeward side of the house. Consult page 6 for
required distances from windows, doors, etc.. The hood location must also allow for a upward slope of a 1/4”
per foot for the exhaust piping.

2” X 2”, Frame a box around the hole on the outside of the house so the flange is mounted away from the
siding. Attach the hood to the outside of the house using appropriate screws to suppor t the hood. Use one
screw through each of the predrilled holes on the trim plate of the hood. Do not drill or screw through the
hood at all.

install the stainless steel flex pipe between the elbow and the reducer on the breeching of the boiler. Be sure
that there is always an upward slope of at least 1/4” per foot of the vent pipe. If at any point the vent pipe is
not able to support itself it should be supported from the ceiling.

Secure each joint with three screws and seal the screws as well.

2.2 Installation of Make-up Combustion Air

For DVH kits:

4. Use 4 inch diameter flex pipe that is provided in the kit or a comparable single wall metal pipe. The
maximum allowable length of intake pipe is ten feet not including elbows.

5. Begin installing the 4” tee to the burner (Riello and Heat Wise require the supplied 3” to 4” increaser to be
installed first). Secure all joints on the intake with three screws each.

6. Install the supplied vacuum relief damper in the branch of the tee making sure that it is mounted with all
labeling right side up and perfectly horizontal.

7. Off of the last leg of the tee install the 4” duct elbow, and then the aluminum flex pipe.

8. Finally attach the other end of the flex pipe to the intake hood or intake port on the concentric hood .

9. Inspect the intake system and make sure all connections are secure and then seal each joint with silicone or
aluminum tape.

Do not operate the burner with air intake disconnected.

3. Burner Setup

In all boilers, regardless of fuel being burnt or configuration, a 10” X 10” Cerafiber pad should be installed
under the flame. This pad is not for acoustic purposes, it is to keep the area under the nozzle warm to prevent
flame out.

Good, reliable operation with a minim um 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 connection s without coup lings 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

To ensure proper burner setup, gauges should be used to check things such as the pump pressure, CO
etc...

) or 6.5% to 3.8% of (O2).

are both properly reinstalled and sealed.

This appliance does not have a pilot. It is equipped with an ignition device which automatically lights the
burner. Do not

A)

BEFORE OPERATING, smell all around the appliance area for gas. Be sure to smell next to the floor

because some gas is heavier than air and will settle on the floor.

try to light the burner by hand.

WHAT TO DO IF YOU SMELL GAS

• Do not try to light any appliance

• Do not touch any electric switch; do not use any phone in you r building

• Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.

5) Smell for gas, including near the floor. If you smell gas, STOP! Follow “B” in the safety
information above on this label. If you don’t smell gas, go to the next step.

6) Turn on all electric power to the appliance.

7) Set thermostat to the desired setting.

8) Once the system is lit, inspect the entire installation.

9) Make sure the pressure in the boiler is stable.

10) Test both 4006A high limits by lowering their set points below the temperature of the boiler one at a time.
If either aquastat fails to shut the burner down replace it immediately.

11) Simulate a loss of fuel by shutting the oil valve. Once the valve is closed the burner shou ld go into post –
purge and then lockout.

12) Reset the burner before turning the oil back on to simulate ignition failure. After ignition failure the
burner should go through a purge period and then lookout.

13) Open the oil valve and return th e burner to operation. While the burner is running, trip the breaker at the
panel, that should disable the burner and all other heating controls.

14) Once it is determined that the system is operating properly, proceed to tuning up the burner using the
proper instruments. If you do not have any instruments, do not place this unit in operation until you have a
competent burner technician tune up the burner.

6. Installation Inspection

Recommended procedures for safety inspection of an appliance should be in accordance with the
National Fuel Gas Code, ANSI Z223.1. The following procedure will help evaluate the venting system. It is
intended as a guide to aid in determining that the venting system is properly installed and is in a safe condition
for continuous use. This procedure should be recognized as a generalized procedure which cannot anticipate all
situations. Accordingly, in some cases, deviation from this procedure may be necessary to determine safe
operation of the equipment. If it is determined that a condition exists which could result in unsafe operation,
the appliance should be shut off and the owner advised of the unsafe condition. Corrections must be made
before the appliance is put into continuous operation. The following steps should be followed in making a
safety inspection.

1. Visually inspect the venting system for proper size and determine that there is no
flue gas spillage , blockage, restriction, leakage, corrosion, or other deficiency which could cause an

unsafe operation.

2. Place in operation the appliance being inspected. Follow the lighting instructions and
adjust thermostat so appliance will operate continuously.

3. Determine that the burner is operating properly and that the burner ignition operates
satisfactorily by interrupting and re-establishing the electrical power of the appliance
in any convenient manner. Test the burner safety device to determine if it is operating
properly by disconnecting the flame safety circuit.

4. Test for smoke spillage at the burner inlet air location around the VRV after 5 minutes of operation. Use
a draft gauge, flame of a match or candle, or smoke from a cigarette, cigar or pipe. Shut off appliance
thermostat and check for spillage around the VRV. If a flow reversal is noticed, house depressurization
is occurring and make up air is required.

Once installation is complete, check the boiler with instruments to ensure that it is working properly.

7. Service & Maintenance

In order to ensure that the boiler is operating properly, it should be inspected annually at the
beginning of the heating season by a qualified service technician. Failure to do regular
maintenance on the boiler, could result in a loss of system efficiency as well as equipment
failure.

1) Turn off all electrical power to the boiler before servicing any part of the boiler.

2) During the inspection process, the technician should inspect and correct problems that

the owner has noted.

3) Check the area around the boiler to ensure that no combustibles are in the area.

4) Remove any obstruction from the ventilation and combustion air openings to the boiler

room. Check to ensure that the openings are open.

5) Check the boiler vent discharge and air intake to ensure that they are unobstructed. If

obstructions exist, remove.

6) Visually check the entire flue gas venting system for blockages, deteriorations and leak-

ages. Repair any problems that are found in accordance with local or national codes.
( Failure to repair leakages can result with CO (Carbon Monoxide) Poising which can
lead to death.)

7) Disconnect vent pipe from the breeching and remove front upper and lower door. Use a

light to inspect the boiler heating surfaces. If signs of soot are showing, clean boiler
heating surfaces with a wire brush and vacuum any debris in the boiler.

8) Reconnect the vent pipe to the breeching. Put silicon back onto the joint and tighten the

clamps before re-commissioning the boiler.

9) With the power to the boiler still off, remove the burner and follow manufactures in-

structions for cleaning.

10) Before putting burner back onto the boiler, check the insulation on the door. If the insu-

lation is damaged or displaced, do not operate the boiler until the insulation has been re­paired or replaced. (Failure to replace damaged insulation can result in a fire hazard and
can cause personal injury or death, and can cause substantial property damage.)

11) Return the boiler to normal operation and check all controls before leaving the job.
