Dear Customer:
Thank you for buying a QHT BIASI B10 Series Boiler.
The QHT BIASI B10 Series Boiler is a cast iron, oil or gas fired hot water boiler, using the
famous BIASI B10 (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 VEGA B10-series boiler
system 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 (L4006A or 7248U) 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 BIASI Boiler blocks are built in accordance with the ASME boiler and pressure vessel code,
and bear the "H" stamp. The entire range of applications for the QHT BIASI B10 Series Boiler
have been tested to CAN/CGA B149 and are ULC compliant.
This BIASI B10 Boiler block 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 as 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.
Thank you for purchasing our QHT BIASI B10 Series Boiler. If you have questions or
comments, please don't hesitate to contact us immediately. Our goal is 100% customer
satisfaction.
Sincerely,
Jim Quincy
QHT Inc.

WARNING
Any appliance that burns natural gas, propane gas, fuel oil, 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:
• Hot gasses from appliance, venting
system pipes or chimney, escaping into
the living space.
• Flames coming out around the appli-
ance.
• 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 OCCUR, OR IF ANY OF THE SIGNS OF CARBON
MONOXIDE ARE PRESENT, VACATE THE PREMISES IMMEDIATELY AND
CONTACT A QUALIFIED HEATING SERVICE COMPANY, THE GAS COMPANY
OR THE FIRE DEPARTMENT.
ONLY QUALIFIED, LICENSED SERVICE CONTRACTORS SHOULD PERFORM
WORK ON YOUR B-10 BOILER.

2. Boiler Block Assembly
All QHT BIASI B10 Series Boilers are shipped from the factory in assembled
boiler blocks. If, however, the block needs to be split into sections for ease of
delivery, please read the following:
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 nipple compound
to both the nipple and port. Install the nipple in the port and then seal by hitting with
a hammer cushioned with a block of wood. Apply section sealant to one section only
and slide sections together. Install the four draw rods and draw the sections together
evenly (measure with yardstick). 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
NOTE: When cutting off excess length of draw rods, allow enough length to install
boiler jacket on the draw rods.

4. Installation of Boiler Trim Components Cont.
1. Install L4006A aquastat in upper left or right rear tapping using 3/4” immersion
well. All tapings and joints should be sealed with piping compound. The L4006A
can be adjusted up to 220o F, and should be set to the desired temperature by
the installer. The differential is also adjustable between 5 and 30 degrees. It
should be set as close to 30 degrees as possible to prevent short cycling of the
boiler. If you are installing a 7248U, Screw the unit to side panel of the boiler as
close to the immersion well as possible using the tabs on the aquastat. Run the
sensor from behind the aquastat to the immersion well and fix it according to
Honeywell’s instructions. The 7248 can be adjusted between 140o F and 220o F
with a fixed differential of 30 degrees.
2. Install Pressure Relief Valve in opposite, upper rear tapping using 3” nipple and
3/4” elbow
3. Install 3/4” boiler drain in lower left or right rear tapping, or lower front tapping.
4. install 3/4” plug in opposite lower rear tapping, and/or the other plug in lower front
tapping of the boiler.
5. Install combination pressure/temperature gauge and 1/2” x 1/4” bushing in upper
front tapping. The gauge must be tightened using a wrench and not your
hand.
6. Install burner mounting hardware in the four tapings on the front of the boiler
door.
7. Install boiler door bolts on opposite side of door hinge.
