Biasi Riva Plus Combi Installation & Operation Instructions page 2

Dear Customer:
Thank you for buying a Biasi Riva Plus Combi.
The Riva Plus Combi is a high effi ciency condensing, wall mounted gas boiler which provides
central heat supply water.
We realize that it is not possible to answer all questions about the Riva Plus Combi 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 qualifi ed, 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 satisfi ed with
your boiler and its performance. We require that your contractor complete effi ciency 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 specifi c recommendations. We re-
alize that other makes and models of such devices are available and can be used as suc-
cessfully as those we specify. The installing contractor is the best judge of a system's specifi c
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 spe-
cifi c devices supplied with every boiler is absolutely necessary to the safe operation of
the boiler and protection of the heating system.
All BIASI wall hung 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 Riva Plus Combi has
been tested to standard CSA 4.9 and is CSA compliant.
This Riva Plus Combi has a 2 year warranty, 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 ratings label affi xed to the boiler), date of installation and the
name of your installer being on record in our fi les.
Thank you for purchasing our Riva Plus Combi. If you have questions or comments, please
don't hesitate to contact us immediately. Our goal is 100% customer satisfaction.
