You have already made the important decision of choosing your U.S. Stove Pellet Burning Room Heater; now
your next step is to determine where to install your new pellet stove heater. To get the most efficient use of re-
circulated heat, you should consider a room that is centrally located within your home. Choose a room that
is large and open. It is Extremely Important to maintain proper clearances from any combustible surfaces or
materials in the room where your heater will be located. You can find proper clearance measurements in this
manual and on the rating label of your pellet stove. The pellet stove can be vented through an exterior wall or
into an existing masonry or metal chimney if “PL” or “L” vent pipe is used throughout existing chimney. Venting
can pass through the ceiling and roof if approved pipe is used. Where passage through a wall, or partition of
combustible construction is desired, the installation must conform to CAN/CSA-B365.

HORIZONTAL EXHAUST VENT INSTALLATION
1. Locate your pellet stove in a location which meets the requirements of this manual, but in an area where it
does not interfere with the house framing, wiring, etc.
2. Install a non-combustible hearth pad underneath the pellet stove. This pad should extend at least 6” (152
mm) in front of the unit.
3.
Place the pellet stove approximately 15” (381 mm) away from the interior wall.
4.
Locate the center of the exhaust pipe of your unit. This point should then be extended to the interior wall of
your house. Once you have located the center point, on the interior wall, cut a 7” (175 mm) diameter hole
through the wall.
5.
The next step is to install the wall thimble, refer to the instructions which come with the wall thimble for this
step.
6. Install the appropriate length of exhaust vent pipe into the wall thimble. See steps 11 and 12 when determining
the correct length of exhaust vent to use.
7.
Outside Fresh Air is Mandatory when installing this pellet stove room heater in airtight homes and mobile
homes. Be sure that the outside air vent has an approved cap on it to prevent rodents from entering. Be sure
to install in location that won’t become blocked with snow, etc.
8.
The air intake pipe is equipped with a butterfly valve that is preset to maximum air intake. For optimum
operating efficiency you may calibrate the butterfly valve to provide less intake air. Caution: Too much
restriction on the intake air will cause dirtier burn, therefore, will require more frequent cleaning.
9.
Connect the exhaust vent pipe to the exhaust outlet of your pellet stove.
10.
Secure all vent joint connections with 3 screws. Seal the exhaust vent joint connections with high temperature
silicone sealant.
11. Push the unit straight back to the interior wall, being sure to maintain the minimum clearances to combustibles
6” (152 mm) to the back of the unit. Seal the annular space of the wall thimble and around the vent pipe with
high temperature silicone sealant.
12. The exhaust vent pipe must extend at least 12” (300 mm) out past the exterior wall. Seal the annular space of
the wall thimble and around the vent pipe with high temperature silicone sealant.
13. Install an approved horizontal termination cap or if necessary install a 90° elbow and appropriate length of
vertical venting. An approved vertical vent cap is recommended.
