The chimney stack dimensions must be calculated in accordance with DIN 4705, or local regulations. For flue gas temperatures below 160 °C, combustion equipment must be connected to highly insulated chimney stacks (heat conductivity resistance class I acc. to DIN 18160 T1) or use suitable, moisture-resistant, type-tested, flue gas systems.

These installation instructions apply exclusively to WOLF oil- and gas-fired boilers as well as to WOLF Unit steel boilers.
Authorised personnel should read these instructions before any installation, commissioning or maintenance work. Adhere to the instructions given in this document.
Non-adherence to these installation instructions voids WOLF warranty.
The following symbols and references are used in these installation instructions: Non-observance of these references can put individuals at risk. Non-observance of these references can lead to damage to the oil/gas-fired boiler or
the Unit boiler. In addition to the installation instructions, operating instructions and adhesive labels
are included or fitted to the boiler. These must also be observed. Observe the enclosed references for heating system installers.
Only qualified and trained personnel may install, commission and maintain these boilers.
In accordance with VDE 0105 part 1, work on electrical components (e.g. control unit) may only be carried out by qualified electricians.
The regulations of VDE/ÖVE and those of your local electricity supplier as well as all other local regulations are apply to electrical installation work.
Only operate the boiler within its output range which is stated in the specification supplied by WOLF.
Appropriate use of the boiler refers to the exclusive use in hot water heating systems in accordance with DIN 4751.
Never remove, bypass or otherwise disable any safety and monitoring equipment. Only operate the boiler in perfect technical condition.
Any faults and damage with a potential impact on safety, which might limit the safe use of the equipment, must be remedied immediately by a qualified contractor.
Replace faulty components or equipment only with original WOLF spare parts.
The boilers described in these installation instructions are low-temperature boilers according to HeizAnlV and 92/42/EEC (Hot Water Boiler Efficiency).
In accordance with the Heating System Order, heating systems above 70 kW may not be operated in single stage mode.
Retain the enclosed operating instructions clearly visible in the boiler room. Insert all further documentation in a clear wallet and clip to the boiler side casing.
Your boiler and burner should be maintained and cleaned on an annual basis by a heating contractor, to ensure the reliable and economic function of your heating system.
We would recommend a maintenance contract. Boilers may only be installed and operated in boiler rooms which are suitable according
to the Landes-FeuVo [or local regulations].

Installation references
Positioning
The boiler should be installed on a level surface which is substantial enough to carry its weight.
It is recommended to place the boiler on a foundation or plinth. For dimensions see the specification.
During the boiler installation observe all building regulations, the FeuVo and VDI 2050 [in Germany] and local regulations, particularly regarding the size of the boiler room, the fresh air and exhaust air ventilation as well as the chimney stack connection.
Only install the boiler in boiler rooms which are free from frost and where adequate ventilation is ensured. Drain the boiler, the DHW cylinder and the entire heating system if there is a danger of frost, if the system has been shut down.
Position the boiler horizontally or slightly rising towards the back to ensure adequate venting of any trapped air.
Boilers should not be installed in areas subject to aggressive vapours or very dusty/ highly humid conditions (workshops, washrooms, hobby rooms etc).
The combustion air must be free from halogenated hydrocarbons (e.g. as contained in sprays, solvents and cleaning fluids, paints and adhesives) and high dust concentration.
Clearances towards walls and combustible materials must comply with local fire regulations. The above clearances are recommended.
Keep the flue pipe connection as short as possible and inclined towards the chimney stack.
Thoroughly seal-in the flue pipe. Use flue pipe bends with clean-out covers to facilitate the cleaning of the flue pipe. Repositioning the fixing screws enables the boiler door to be opened in the opposite
hand.
