Installation instructions

4 220 456 / 02 - 03/21

Hoval products must be installed and commissioned

by specialists only. These instructions are intended for

service engineers

. Electrical installation must be per

formed by a licensed electrical company.

Floor-standing gas condensing boilers UltraGas

(125-1550) acc. to EN 15502-1/15502-2-1 are suitable

and licensed for use as heat generators for hot water

heating systems with a permissible flow temperature of

up to 95 °C

. They are designed for continuously con

trolled reduced operation in heating systems.
