2. Vent surfaces can become 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.
