Outside air flex pipe 

goes here.

Outside Air:

Hearth & Home Technologies recommend attaching 

outside air in all installations, especially lower level and 

main floor locations.

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 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.
When the appliance is roof vented: The air intake is best 

located on the exterior wall oriented towards the prevailing 

wind direction during the heating season.
The outside air connection will supply the demands of the 

pellet  appliance,  but  consideration  must  be  given  to  the 

total house demand. House demand may consume some 

air needed for the stove, especially during a power failure. 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. 
To install outside air use 3" non-combustible flex pipe Figure 

4.13. There is a break-away hole on the rear panel of the 

Absolute43 stove which must be removed before connecting 

the flex pipe. Figure 4.12. The pipe should be run outside and 

terminate to the side or below the vent pipe outlet so the flue 

outlet is more than 12" from the inlet cover. The Termination 

Cap should be used to keep birds, rodents, etc. out of the 

pipe Figure 4.13.
You may choose to use the optional Direct Vent Wall Pass-

through Kit which incorporates the venting pass-through and 

outside air inlet into one component. Figure 4.14.
