INTRODUCTION
Dear Customer,
Thank you for choosing a TP3 COND boiler. This manual has been prepared in order to provide instructions and advice on the installation,
proper use and maintenance of the boiler.
Please read it carefully and keep it for further consultation. Carefully follow the instructions provided, to ensure the best use of this high
quality product. Failure to comply with that given in this manual exonerates the Manufacturer from any liability and voids the warranty.

TECHNICAL, CONSTRUCTIVE AND DIMENSIONAL CHARACTERISTICS
4.1 Description of unit
The type of construction of TP3 COND series boilers ensures high performance and high efficiency with low fume temperatures, resulting
in reduced pollutant emissions.
The main technical elements of the design are:
• Careful study of the geometries, to obtain an optimum combination of combustion volumes and exchange surfaces.
• The choice of materials used, to ensure long service life.
These boilers feature pressurized combustion, with triple gas pass, double overlaid cladding and firebox totally wet at the top and tube
bundle at the bottom, holding the turbulators that create a swirling path, increasing the heat exchange by convection. At the tube bundle
outlet the fumes are collected in the rear chamber and conveyed to the flue. The boilers have a hinged door for right or left opening, adjust-
able in height and depth. The shell is insulated with a thick glass wool mat and covered with an additional layer of tear-resistant material.
The exterior finish consists of painted steel panels. Lifting hooks are located on top of the boilers.
The boilers have two 1/2" attachments for bulb holder sheaths (suitable for holding 3 bulbs each).
The pre-wired control panel (to be ordered separately) will be placed in the special housing in the boiler shell and allows automatic opera-
tion of the boiler.
4.2 Working principle
TP3 COND boilers have a totally wet blind cylindrical firebox in which the first gas pass is developed, a larger firebox return tube (2nd pass)
and a tube bundle at the bottom (3rd pass). At the tube bundle outlet the fumes are collected in the rear smoke chamber and conveyed to the
flue. The combustion chamber is always pressurized when the burner is working. For the value of this pressure, see the table on page 38 at
"Fume side pressure losses". The flue and flue connection must comply with the current Standards and Legislation, using rigid pipes that are
resistant to heat, condensate and mechanical stresses, and be tight (Fig. 1).
