Safety Requirements at the place of installation 2.3 Requirements at the place of installation 2.3.1 Approval for the heating system The appropriate supervisory authority (inspection agency) must always be informed when installing or modifying a heating system, and authorization must be obtained from the building authorities.
You can add anti-freeze to the heating water, however, this can reduce the heating ef‐ ficiency. Always follow the manufacturer’s dosing instructions when using anti-freeze, as using the incorrect amount can cause corrosion. Check the concentration of the an‐ ti-freeze at regular intervals. Froling GesmbH | A-4710 Grieskirchen, Industriestraße 12 | www.froeling.com...
Safety Requirements at the place of installation 2.3.4 Ventilation requirement for boiler room Introduction The external combustion air must meet certain requirements to ensure that adequate combustion air is supplied to the boiler and no by-products from the combustion get into the boiler room.
If the outside temperature is low, condensation water can freeze at the chimney outlet, which can result in inade‐ quate chimney escape, limited boiler output and a system breakdown. Froling GesmbH | A-4710 Grieskirchen, Industriestraße 12 | www.froeling.com...
Safety Requirements at the place of installation 2.3.9 Requirements for the chimney connection The chimney connection must be big enough to channel flue gases from the building. The whole flue gas system must be designed to prevent possible seepage, insufficient feed pressure and condensation.
Securing the main switch Switch off the main switch and secure with a padlock when carrying out maintenance work to the boiler. Froling GesmbH | A-4710 Grieskirchen, Industriestraße 12 | www.froeling.com...

Heating the boiler Before heating up the boiler Calculation To calculate the energy required we use the formula Q = m x c x Δt. Q = energy required m = mass of the medium to be heated c = heat capacity of the medium to be heated (constant for water) Δt = temperature difference between start and end temperature The amount of fuel can be calculated from the energy required and the energy content of the fuel.
❒ If too much fuel is added, the boiler will drop below its minimum output limit and enter into the “Slumber” operating status (blower fan is switched off) ➥ During “Slumber”, the efficiency drops, emissions increase and tar may form in the boiler.
