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 sun
deck or porch, or any location
that can build up a concentration
of fumes such as stairwells,
covered breezeway, etc.
2. Vent surfaces can
hot enough to cause burns
if touched by children. 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 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. This will 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.
4. Distance from the bottom of the termination and grade is 12" (30 cm) 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.
5. 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 the control of Sherwood Industries Ltd, we grant no guarantee against such
incidents.
NOTE: Venting terminals shall not be recessed into walls or siding.
