2 KAPPA R USER MANUAL
Dear Customer:
Thank you for buying a Biasi KAPPA R Boiler System.
The KAPPA R is an efcient oor standing gas red boiler for central heat.
We realize that it is not possible to answer all questions about the KAPPA R 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 qualied, 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 satised with your boiler and its performance. We require that your contractor complete efciency tests using
instruments.
The external controls and accessories listed in this manual (excluding those supplied inside the boiler) are intended
to serve as guidelines rather than specic 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 specic 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 and pressure relief valves. The installation of the specic devices supplied with every boiler is
absolutely necessary to the safe operation of the boiler and protection of the heating system.
All BIASI KAPPA R boilers are built in accordance with the ASME boiler and pressure vessel code, and bear the “H”
stamp. The Entire range of applications for the KAPPA R boiler has been tested to standard ANSI Z21.13/CSA4.9
and is CSA compliant.
This KAPPA R boiler has a 1 year warranty on parts and a limited lifetime warranty on the heat exchanger only.
Please be sure to return the warranty registration card as the warranty will be void without your boiler’s serial numbers
(located on label afxed to the boiler), date of installation and the name of your installer being on record in our les.
Thank you for purchasing our KAPPA R boiler. If you have questions or comments, please don’t hesitate to contact
us immediately. Our goal is 100% customer satisfaction.

KAPPA R USER MANUAL 5
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. 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 inuenza, and the highest incidence of poisoning
occurs at the onset of cold weather or during u 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 ames 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 OR
THE FIRE DEPARTMENT.
ONLY QUALIFIED, LICENSED SERVICE CONTRACTORS SHOULD PERFORM WORK ON YOUR BIASI
KAPPA R BOILER.

3. Instructions for Use
3.1 Warnings:
• In order to guaranty safety and correct operation, it is essential that all the tests are carried out by a competent
and responsible licensed service person before lighting up the boiler.
• The tests are described in the installation, operation and service instructions manual in Section 11 Start Up and
Check Out.
• Ensure that the Central Heating circuit is regularly lled with water checking that the pressure indicated on the
pressure gauge is not lower than 1 bar (14.5 psi) as shown on Figure 3.1.
• If the pressure reading on the pressure gauge is below 1 bar (14.5 psi), then the system will require lling. An
automatic lling valve is normally provided by the installer for this purpose.
• If you are in any doubt regarding this procedure you are advised to contact your Installer or an Approved
Service Person.
• Therefore, when the boiler is not lit or used in cold weather, with consequent risk of freezing do not switch off
the boiler at the circuit breaker or close the gas inlet cock.
• When you expect not to use the boiler for a long period follow the instructions given in section 3.4 on page 11.
3.2 Relling Procedure:
• Isolate the boiler from the electrical supply at the circuit breaker.
• The boiler should have been installed with an automatic ll valve, external to the unit. Open the cold water supply
to the automatic ll valve.
• The pressure should be 1 – 1.5 bar (14.5 – 22 psi).
• The automatic ll valve should maintain this pressure, but not exceed it.
Figure 3.1 (Pressure gauge)
Air introduced into the boiler during this lling process will vent through the automatic air purger tted to the boiler.
You may also nd it necessary to vent air from your heating circuit using the installed vents, however be aware that
excessive venting will cause the pressure in the system to drop. Always ensure that the pressure gauge is set at the
required pressure.
