  • Page 8 It is forbidden to install appliances removed from other systems. The manufacturer declines all liability in the event of damage caused by appliances removed from other systems or for any non-conformities with such equipment. Check the environmental operating conditions of all parts relevant to installation, referring to the values shown in the techni- cal data table in this booklet.
  • Page 9 The minimum distance for exhaust pipes from flammable materials must be at least 25 cm. Keep all combustible material away from the appliance (paper, rags, plastic, polystyrene, etc.). Split exhaust ducts must not pass through walls of combustible material. Do not place household appliances underneath the appliance as they could be damaged if the safety valve intervenes, if the drain trap is blocked, or if there are leaks from the hydraulic connections;...
  • Page 10 Installation standards This type of installation is possible when permitted by the laws in force in the appliance's country of destination. This appliance can be installed outdoors in a partially protected area. By partially protected area, we mean one in which the unit is not directly exposed to the elements (rain, snow, hail, etc.). Installation of gas appliances, flue exhaust pipes and combustion air intake pipes is forbidden in places with a fire risk (for example: garages, closed parking stalls), and in potentially dan- gerous places.
  • Page 11 These appliances are used to heat water to below boiling temperature in atmospheric pressure. They must be connected to a central heating system and domestic hot water circuit (when combined to a storage tank unit) suit- ed to their performance and capacity. The storage tank unit, if present, must also be installed in an environment in which the temperature cannot fall below 0°C.

  • Page 13 Filling the condensate drain trap When the appliance is switched on for the first time, combustion products come out of the con- densate drain. After a few minutes of operation, check that combustion flue gases are no longer coming out of the condensate drain; this means that the drain trap has filled to a correct con- densate height that the flue gases cannot pass through.
