Enviro FS, FPI, BIH Deciding Where to Locate Your Pellet Appliance, Vent Termination Requirements

DECIDING WHERE TO LOCATE YOUR PELLET APPLIANCE

1.Check clearances to combustibles.

2.Do not obtain combustion air from an attic, garage or any unventilated space. Combustion air may be obtained from a ventilated crawlspace.

3.Do not install the stove in a bedroom.

4.You can vent the stove through an exterior wall behind the unit or connect it to an existing masonry or metal chimney (must be lined if the chimney is over 6” in diameter, or over 28 sq. inches cross sectional area). An interior vent can be used with approved pipe passing through the ceiling and roof.

5.Locate the stove in a large and open room that is centrally located in the house. This will optimize heat circulation.

6.The power cord is 8 feet (2.43 m) long and may require a grounded extension cord to reach the nearest electrical outlet.

VENT TERMINATION REQUIREMENTS

A.Do not terminate the vent in any enclosed or semi-enclosed areas such as a carport, garage, attic, crawlspace, narrow walkway, closely fenced area, under a sundeck or porch, or any location that can build up a concentration of fumes such as stairwells, covered breezeway, etc.

B.Vent surfaces can become hot enough to cause burns if touched by children. Non-combustible shielding or guards may be required.

C.Termination must exhaust above the inlet elevation. It is recommended that at least five feet of vertical pipe be installed outside when the appliance is vented directly through a wall to create some natural draft to prevent the possibility of smoke or odor during appliance shut down or power failure. To keep exhaust from causing a nuisance or hazard from exposing people or shrubs to high temperatures. In any case, the safest and preferred venting method is to extend the vent through the roof vertically.

D.The vent terminal cannot be:

-Less than 4 feet (1.2 m) below

-Less than 4 feet (1.2 m) horizontally from, and

-less than 1 foot (305 mm) above Doors, window openings, or gravity/ventilation air inlet into building:

E.Distance from bottom termination and grade –12” (305 mm) minimum. This is conditional upon the plants and nature of grade surface. The exhaust gases are hot enough to ignite grass, plants and shrubs located in the vicinity of termination. The grade surface must not be lawn. Distance from bottom of termination and public walkways is 7 feet (2.1 m) minimum.

F.Distance to combustible materials is 2 feet (610 mm). This includes adjacent buildings, fences, protruding parts of the structure, roof overhang, plants, shrubs, etc.

G.When installing an FPI or BIH the chimney must be fully lined. Unless the chimneys inside diameter are less than 6” around or has a cross section area of less than 28 square inches. We strongly recommend lining all masonry chimneys.

H.If the unit is incorrectly vented or the air to fuel mixture is out of balance, a slight discoloration of the exterior of the house might occur. Since these factors are beyond Sherwood Industries Ltd.'s control, we grant no guarantee against such incidents.

IT IS RECOMMENDED THAT ONLY AN AUTHORIZED DEALER INSTALL YOUR PELLET STOVE
