1.2.4 Ventilation of boiler room
During the installation of your boiler provision must be made by the
installer to provide a source of combustion air for the boiler.
Maintaining this combustion air source is critical for proper operation of
your boiler, do not close off, block or otherwise obstruct the combustion
air source for your boiler. If you have questions regarding the
combustion air source please contact your installer.
Provision for outside combustion air may be necessary to ensure that
fuel-burning appliances do not discharge products of combustion into
the house. Guidelines to determine the need for additional combustion
air may not be adequate for every situation. If in doubt, it is advisable
to provide additional air. The Froling FHG, due to its powerful Induced
Draft Fan, needs adequate air to make up for the air being pushed up
the Chimney, especially during start up before the Chimney is warm.
The openings for the combustion air and the exhaust air should be
arranged as nearly opposite each other to achieve a good thermal draft
effect.

The combustion air must be drawn in directly from outside. The
exhaust air must be discharged directly to outside.
Both openings for air intake and exhaust air shall be well protected from
any interference caused by environment, as weather, snow, greenery,
small animals, etc.
Froling FHG boilers are not suitable for direct connection to outside air.
Outside air should be ducted to no closer than 12” (30 cm) from the
boiler. A 6” (150 mm) duct should be large enough for all sizes unless
the duct run is over 25 feet (7.6 m).
In addition to local codes and regulations a minimum cross section of
combustion air and exhaust air shall be 28 sq.in. (180 cm²) each.
Account for the reduced cross section area if gratings or fins are used!

IMPORTANT: Canada must conform to ANSI/NFPA outside air
requirements of 1 sq. inch per 1,000 Btu/hr.
1.2.5 Installing the heating system
The entire heating system has to be designed according relevant
national and local codes. The nominal power of the Central Heating
Boiler shall be corresponding to the calculated heat demand for all
heating appliances connected to the heating system both in summer and
winter time.
The heating system must be able to carry all heat produced by the
Central Heating Boiler and additional heat source, if applicable. The
whole heating system as well as all heating zones have to be
hydraulically balanced.
Special arrangements have to be provided for initial filling or re-filling
and bleeding of all heating zones. Flow-check valves and zone-valves
have to be installed for proper adjustment of water flow rates. All piping
must be water and air tight and insulated safely.
For the heating system piping, it is possible to use either copper or iron
piping materials. The supply and return water pipe should be insulated
to avoid heat loss. Included in chapter "3.6 System plumbing" are
conceptual piping diagrams showing the correct layout for a variety of
situations. Tarm Biomass can provide additional conceptual plumbing
diagrams.
