TROUBLE SHOOTING GUIDE
If the ventilation system is not operating
correctly check the following items.
1. Do the ducting pieces look like the examples
in the Duct Length Chart? The system should be
constructed using the examples shown in the
Duct Length Chart. The duct work should not
exceed 60 equivalent feet.
2. Were two elbows used together to get around
a floor joist or wall stud? Two elbows should not
be installed together. They will create a poor
vent path.
3. If cooking odors are filtering back into the
house, answer the following questions. Was the
system vented outside? Was the system vented
into the attic or a crawl space? The system must
be vented outside. Are all of the duct joints
sealed with duct tape? All joints must be sealed
with duct tape.
4. Was flexible ducting used in the installation?
Flexible plastic ducting should not be used. If
flexible metal ducting is used, each bend should
be counted as two metal duct elbows. A flexible
metal duct must be calculated as twice the length
of straight 6" metal duct.
5. Does the size of the ducting change? All
ducting should be the same size.
6. Is the ducting clear of all foreign matter?
Clear entire ducting. Foreign matter in ducting
will restrict air flow.
7. Has a piece of ducting collapsed? Replace
damaged ducting.
8. Is there a draft in the range area? Try to
eliminate the draft and check the operation.
9. How high above the ground is the wall cap? If
the cap is too close to the ground, air velocity
will bounce off the ground and return into the
wall cap, restricting the exhaust flow.
REMOVAL AND REPLACEMENT OF RANGE
1. Disconnect the electrical supply at the house
circuit breaker.
2. Disconnect the range venting.
3. Unplug the power supply cord.
4. Remove the anti-tip bracket.
5. Install the anti-tip bracket into the new
location using the instructions provided with
the bracket.
6. To replace the range follow the Installation
Instructions.
