MT VERNON E2-C
B. Avoiding Smoke and Odors

Negative Pressure, Shut-Down and Electrical Power 

Failure

To reduce the probability of back-drafting or burn-back in 

the pellet appliance during power failure or shut down con-

ditions, it must be able to draft naturally without exhaust 

blower operation.  
Negative pressure in the house will resist this natural draft if 

not accounted for in the pellet appliance installation.

Heat rises in the house and leaks out at upper levels.  This 

air must be replaced with cold air from outdoors which flows 

into lower levels of the house.  
Vents and chimneys into basements and lower levels of the 

house can become the conduit for air supply and reverse 

under these conditions.

Outside Air

An outside air kit (OAK-3) is recommended in all installations 

and  must be ordered separately.
Per national building codes, consideration must be given to 

combustion air supply to all combustion appliances.  Failure 

to supply adequate combustion air for all appliance demands 

may lead to back drafting of those and other appliances.  

When the appliance is roof vented (strongly recommended):  

The air intake is best located on the exterior wall oriented 

towards the prevailing wind direction during the heating 

season.

When the appliance is side-wall vented: 

The air intake is best located on the same exterior wall as 

the exhaust vent outlet and located lower on the wall than 

the exhaust vent outlet.

The outside air supply kit can supply most of the demands of 

the pellet appliance, but consideration must be given to the 

total house demand.  
House demand may consume the air needed for the appli-

ance.  It may be necessary to add additional ventilation to 

the space in which the pellet appliance is located.  
Consult with your local HVAC professional to determine the 

ventilation demands for your house.

Vent Configurations

When installing a pellet appliance with a horizontal vent con-

figuration the frequency of power outages should be consid

-

ered:

•  Power outages during operation will cause the appliance 

to immediately turn off and may create conditions where 

smoke will back draft into the house. In order to reduce 

the likelihood of smoke back drafting into the house 

during a power outage, Hearth and Home Technologies 

strongly suggests:

•  Installing the pellet venting with a minimum vertical 

run of 5 feet (1.52m).

•  Installing the outside air kit at least 4 feet (1.22m) 

below the vent termination.

To prevent soot damage to exterior walls of the house and to 

prevent re-entry of soot or ash into the house:

  •   Maintain  specified  clearances  to  windows,  doors  and 

air inlets, including air conditioners.

  •   Vents  should  not  be  placed  below  ventilated  soffits.  

Run the vent above the roof.

  •   Avoid venting into alcove locations.
  •   Vents should not terminate under overhangs, decks or 

onto covered porches.

  •   Maintain minimum clearance of 12 inches (305mm) 

from the vent termination to the exterior wall.  If you 

see deposits developing on the wall, you may need to 

extend this distance to accommodate your installation 

conditions.

CAUTION

•  DO NOT CONNECT THIS Appliance TO A CHIMNEY 

FLUE SERVICING ANOTHER APPLIANCE.

•  DO NOT CONNECT TO ANY AIR DISTRIBUTION DUCT 

OR SYSTEM.
