Mechanical Room
During the early stages of new home design, we recommend that proper
consideration be given to constructing a separate mechanical room dedicated to gas
or oil fired equipment including domestic hot water storage tanks.
The boiler should be located in a heated indoor space, near a floor drain, and as
close as possible to the vertical chimney or vent.
Install the boiler on a concrete foundation if:
- the floor may be flooded,
- the floor is not level,
- the boiler will be installed in a residential garage (in this case ensure that the
burner is raised at least 18” / 457 mm above the floor to avoid contact with
flammable vapors and fumes).
Viessmann strongly recommends installing the boiler on a concrete foundation.
Whenever possible install boiler near an outside wall so that it is easy to duct fresh
air directly to the boiler area. In addition, do not use exhaust fans in the boiler room
and do not install the boiler in rooms with refrigeration equipment. This equipment
requires uncontaminated outside air for safe operation - do not install where
chemicals are stored or in a room with negative pressure. See section entitled
“Combustion Air Supply” for further details regarding the above.
Locate boiler on flooring capable of supporting the weight of the boiler filled with
water. Ensure that the boiler location does not interfere with the proper circulation
of combustion and ventilation air within the mechanical room.
