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.
