7. ADDITIONAL GAS-FIRED HEATING OPTION
7.1. Introduction
In URTP devices, there is optionally an alternative system to water or electric heating systems with
additional gas fired heating module. One of the fuel types of natural gas should be used for gas fired
modules. These units have condensation technology and are devices with high efficiency.
Information given in the table below about gas fired heating module that used in URTP units.
