HEARTH PROTECTION
VENT TERMINATION REQUIREMENTS
The floor protector must be a non-combustible material extending beneath
the stove and to the front and sides as shown below.
Minimum Size Hearth Protection
1. 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.
2. Vent surfaces can become hot enough to cause burns if touched.
Non-combustible shielding or guards may be required.
3. Termination must exhaust above the inlet elevation. It is recommended
that at least five feet of vertical pipe be installed outside when the
stove is vented directly through a wall. This will create a natural draft
to prevent the possibility of smoke or odor during appliance shut
down or power failure and avoid exposing people or shrubs to high
temperatures.
4. The vent should terminate no less than four feet below, no less than
four feet horizontally from and no less than one foot above doors and
windows, or gravity/ventilation air inlets into the building.
5. The distance between the bottom of termination and grade should be
a minimum of 12” (305 mm). The distance between the bottom of
the termination and a public walkway should be a minimum of seven
feet.
6. Locate the vent termination at least two feet away from combustible
materials such as shrubs, plants, grass, fences, roof overhangs and
adjacent buildings.

Alcove Installations
Minimum alcove height is 41” (1041 mm), minimum width is 42-1/4” (1073
mm) and maximum depth is 48” (1219 mm). Note, it is quite difficult to
load pellets into the hopper when installed in an alcove only 41” (1041
mm) high. For alcove wall clearances see parallel clearances below.
