Combustion Air; Chimney Venting - ENERGY KINETICS EK3 Frontier Owners & Installation Manual

COMBUSTION AIR

The System 2000 Boiler must be installed in an area where adequate fresh air is available to support combustion.
The EK3 Frontier can be provided with a sealed Air Box that can be piped to air outside the building.
Boiler with outside air piping: Piping of outside air directly to the boiler is highly recommended because it completely
isolates the boiler from the interior environment, as well as greatly reducing operating noise from the boiler. In multiple
boiler installations, each boiler air intake should be piped separately. The outside air source must be located high enough
above grade to be at least 12" above expected snow accumulation. Use 4" PVC to pipe in the fresh air, 20 feet max and
five 90 degree elbows or less. Up to 40 feet max using 5" PVC and five 90 degree elbows or less.
Boiler without outside air piping:
WARNING:
The confined space shall be provided with two permanent openings, one near the top of the enclosure and
one near the bottom. Each opening shall have a free area of not less than one square inch per 1,000 BTU
per hour of the total input rating of all appliances in the enclosure, freely communicating with interior areas
having adequate infiltration from the outside.
WARNING:
Modern buildings of tight construction, as well as the operation of attic and exhaust fans, kitchen ventilation
systems, clothes dryers or fireplaces may create conditions of unsatisfactory combustion or venting.
Provisions must be made to use combustion air that communicates with a well-ventilated attic or with the
outdoors (such as using a louver or grate). The opening should have a free area of not less than one (1)
square inch per 4,000 BTU per hour of the total input rating.

CHIMNEY VENTING

WARNING:
Masonry chimneys must have a tile or metal liner. The liner must:
1) Extend above the masonry.
2) Have an insulating air gap, isolating the liner from the chimney, allowing for rapid heat-up and draft
establishment.
3) Be sealed at each joint to prevent air infiltration and damage from condensation.
NOTICE:
Inspect Chimney and Chimney base after initial three months of operation.
The installation of a chimney cap is recommended. The base of the chimney must always have a drop leg below the
flue connector to allow scale and condensation to accumulate without blocking the flue pipe.
CAUTION:
If drop leg is in excess of 12 inches deep, backfill with loose gravel or sand to obtain a maximum of 12-
inches depth. All clean out doors must be sealed to prevent cold air entry into chimney.
In retrofit installations, have chimney thoroughly cleaned. Carefully inspect chimney, base of chimney, and liner prior
to installation of System 2000 Boiler.
CAUTION:
If liner is not sound, or if existing tile liner fails to contain intermittent condensation, or if excessive debris is
found at the base of the chimney, then it is recommended to install a properly sized metal liner approved for use with oil
heat appliances.
The metal liner diameter and length should be as recommended by the metal liner manufacturer. Corrugated metal
liners should be at least 8" diameter. Connection of a flexible metal liner directly to the flue collar of the boiler is an
acceptable connection method and is recommended. Alternatively, a flexible metal vent connector may be used between
the flue collar of the boiler and a flexible metal liner. Call Energy Kinetics for details on metal liners.
Chimney connectors should be positioned to create the shortest possible run of flue pipe to the chimney. The overall
horizontal length of flue piping should not exceed 15 feet. Long runs or low firing rates may require insulated flue pipe
such as L-Vent or All-Fuels to keep the temperature at base of chimney adequate for draft and to prevent corrosion of
piping and connectors.
Because the System 2000 boiler uses a power burner, the flue pipe may experience some positive pressure on start
up. Energy Kinetics recommends that all pipe joints be sealed with high temperature silicone sealant to ensure passage
of all combustion products to the chimney.
Normally, pitch horizontal flue pipe up toward chimney approximately ¼" per foot. For existing installations, it is
permissible for the flue connection of the boiler to be higher than the chimney thimble, provided adequate draft is
established.
If a minimum of +0.08" w.c. draft overfire is not present after sufficient burner run time to heat up the chimney, there is
a problem that will need to be corrected. Call Energy Kinetics for help resolving draft problems. Under normal
circumstances, there is NO need for a DRAFT REGULATOR and one should not be installed. Call Energy Kinetics with
questions about flue pipe sizing.
WARNING:
No solid fuel appliance or fireplace should be installed in a flue common with this heating appliance. The
flue gas exit of the venting system must be at least three (3) feet above the point at which it passes through the roof and
at least two (2) feet higher than any portion of a building within 10 feet horizontally of its location.
