Mechanical Room - Viessmann VITOLIGNO 300-C Installation And Service Instructions Manual

Vitoligno 300-C Installation/Service

Mechanical Room

During the early stages of designing a new home, we recommend that proper consideration be given to constructing a
separate mechanical room dedicated to the wood pellet fired heating equipment and domestic hot water storage tank(s),
as well as method and location of wood pellet storage facility.
The boiler must be located in a heated indoor area, near a floor drain, and as close as possible to a wall. Whenever
possible, install the boiler near an outside wall so that it is easy to duct the venting system to the boiler.
Ensure that the boiler location does not interfere with the proper circulation of combustion and ventilation air of other
fuel burning equipment within the mechanical room (if applicable).
The maximum room temperature of the mechanical room where the boiler is located must not exceed 95ºF (35ºC).
Installation area conditions
WARNING
Incorrect ambient conditions can lead to damage to the
heating system and put safe operation at risk.
H Ensure ambient temperatures are higher than 32°F
(0°C) and lower than 95ºF (35ºC).
H Prevent the air from becoming contaminated by
halogenated hydrocarbons (e.g. as contained in paint
solvents or cleaning fluids) and excessive dust (e.g.
through grinding or polishing work). Combustion air
for the heating process, and ventilation of the boiler
room must be free of corrosive contaminants. To that
end, any boiler must be installed in an area that has no
chemical exposure. The list to the right indicates the
main, currently known sources.
H Avoid continuously high levels of humidity (e.g. through
frequent drying of laundry).
H Never close existing ventilation openings.
WARNING
If you notice fire coming from the appliance, call the fire
department immediately! Do not attempt to extinguish
the fire unless qualified to do so.

WARNING
Suffocation hazard due to carbon monoxide produced
during incomplete combustion due to lack of combustion
air. Ensure an adequate supply of fresh air. Never cover
or close vents.
