4.7 Location in Boiler Room

Pay special attention to local regulations and laws about boiler enclosures and boiler rooms,
particularly to the minimum clearances around the boiler. The installation must be in compliance
with all regulations and laws about boiler enclosures, boiler rooms, installations of heating and
hot-water systems, ventilation, 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 4-3), in order to assemble the condensate
trap. An alternative to this base may be a 100 mm deep well or trench next to the boiler to
accommodate the condensate "U" drain pipe (see Figure 4-3). After installation the boiler shall
be perfectly horizontal and stable, to reduce any possible vibrations or noises.

4.7.1 Boiler Room Safety Concerns

When selecting the position for the installation of the boiler comply with the following
requirements:
• Ensure easy access to the components of the boiler to facilitate maintenance.
• The room where the boiler will be placed must always be frost free.
• Do not store or use gasoline or other flammable vapors and liquids in the vicinity.
• Never use or store any chlorinated detergents or halogenated hydrocarbons (e.g. in spray
cans, solvents and detergents, paints, adhesives) in proximity to the boiler.
W A R N I N G !
If installing to an outdoor location where freezing temperatures may occur, it is necessary to install devices
and/or materials to prevent any freezing in the condensate drain and the Flow and Return manifolds.
Failure to do so may cause serious damage to the equipment.
