2. Description
2.1. Fully modulating gas condensing unit
The PYROGAS VARINO condensing unit sets new standards for energy-saving heat generation from natural
gas. The unique power modulation range up to 1:12 enables an almost continuous operation during the main
period of the heating season. Based on the drastically reduced number of starting and stopping processes and
the low average use of power this results in considerable benefits in relation to environmental loading and
efficiency. In addition, reactions to changes in heat consumption are faster since the condensing unit is already
working, as a rule, due to the long running times of the burner.
The unique power modulation range up to 1:12 is achieved by a complete pre-mix burner with moving burner
surface, which is extended in proportion to the heat consumption. With an increase in power the active burner
surface with the flame openings is enlarged. At the same time the volume of gas and air is increased so that the
individual flames do not change but merely increase in number. The special, patented design of the flame
openings enables minimum emissions of carbon monoxide and nitric oxide.
The burner control based on a micro-processor with fan speed correction ensures a uniform combustion quality.
Local conditions relating to the unit such as geographic height, flue, ingoing air lines, etc. are automatically
recorded during commissioning and corrected by the computer. In addition, daily deviating effects such as air
pressure changes, temperature changes, changes in the composition of natural gas, etc. are taken into
consideration by permanently checking the oxygen concentration in the flue gas by means of an oxygen sensor
and the control of the required speed of the fan. This results in an additional saving in electric energy.
Control takes place via optional modules to all accessible interfaces found on the market (e.g. digital control,
0-10V or bus) in addition to in-built external temperature control (option).

The boiler body consists of parts in contact with flue gas made out of high quality stainless steel. The concept of
maintaining the return temperature can therefore be dispensed with. The high and low temperature returns
enable simultaneous supply of return water with high and low temperature without impairing the efficiency of the
heat exchanger by forming a mixing temperature. The heat exchanger and condenser are constructed in a
natural circulation design so that operation is possible with a random combination of high and low temperature
