CHAPTER 4: Installation Instructions

4.6 BOILER LOCATION INSIDE A BOILER ROOM

Special attention shall be paid to local regulations and laws about boiler enclosures and boiler
rooms, particularly to the minimum clearances around the boiler. The installation shall be in
compliance with all the latest regulations and laws about boiler enclosures, boiler rooms,
installations of heating and hot-water systems, ventilation, vents capable of exhausting the flue
gases of condensing boilers, and any other applicable requirements.
The boiler can be put on a flat and sufficiently strong base with the same dimensions as the
boiler and at least 3.93'' (100 mm) high (see Figure 4-7), in order to assemble the condensate
trap. An alternative to this base may be a 100mm deep well or trench next to the boiler to
accommodate the condensate "U" drain pipe (see Figure 4-7). After installation the boiler shall
be perfectly horizontal and stable, to reduce any possible vibrations or noises.
