Combustion/room air

▶ Keep the combustion/ambient air free of corrosive 

substances (e.g. halogenated hydrocarbons that 
contain chlorine or fluorine compounds). This will 
help to prevent corrosion.

▶ Keep the combustion air supply free of dust.

H

Danger posed by explosive and easily 
flammable materials

▶ Never use or store easily flammable materials (e.g. 

paper, thinners, paints, etc.) near the appliance.

H

Heating system damage due to frost

When the heating system is not in operation (e.g. 
controller switched off, fault shutdown), there is a risk 
of it freezing when there is frost.

▶ When shutting down or switching off for extended 

periods, drain the heating and drinking water pipes 
to the lowest point in order to protect the heating 
system from freezing.

H

Inspection and servicing

Recommendation for customers:

 Arrange a 

maintenance and inspection contract with an 
approved contractor, covering an annual inspection 
and responsive maintenance.

▶ The user is responsible for ensuring the heating 

system is safe and environmentally compatible.

▶ Immediately correct all faults to prevent system 

damage!

▶ Use only genuine spare parts from the 

manufacturer. Losses caused by the use of spare 
parts and accessories not supplied by the 
manufacturer are excluded from the manufacturer's 
warranty.

H

Handover to the user

When handing over, instruct the user how to operate 
the heating system and inform the user about its 
operating conditions.

▶ Explain how to operate the heating system and draw 

the user's attention to any safety relevant action

▶ Explain that conversions and repairs must only be 

carried out by a competent person.

Product Description

The Uni Condens 8000 F 800...1200 is a floor standing condensing 
boiler with a slim, compact design and a small footprint, comprising a 
combustion chamber located at the top and a condensation heating 
surface located at the bottom.

With the Uni Condens 8000 F 800...1200 floor standing condensing 
boilers, all parts that come into contact with products of combustion or 
condensate are made from high grade stainless steel. This makes 
operation possible without limitations on the flow and return 
temperature, the flow rate or the burner low load.

The Uni Condens 8000 F 800...1200 is also referred to in this manual as 
UC8000F 800...1200, boiler or heat source.

The boiler has two separate thermohydraulic return connections for the 
high and low temperature heating circuits (

 fig. 1, page 5).

The Uni Condens 8000 F 800...1200 must be equipped with a burner 
that is suitable for the boiler. 

The main components of the boiler are (

 fig. 1, page 5):

• Boiler shell [1] in conjunction with a burner 

The boiler block transfers the heat produced by the burner to the 
heating water.

• Thermally insulating casing 

The boiler shell and thermal insulation reduce energy losses.

• Control unit (accessory) [8]

The control unit monitors and controls all electrical boiler 
components.

This symbol is used to point out that the installation and 
operating instructions must be read prior to installation 
operation or maintenance in order to prevent damage to the 
system.
