Exhaust Spillage And Testing Procedure - Quadra-Fire GB40I Installation & Operating Instructions Manual

EXHAUST SPILLAGE AND TESTING PROCEDURE

There is a spill switch located on the back of the insert below the draft hood, which is designed to shut down
the insert due to a blocked flue or a severe down draft. The switch acts as a safety shutoff to prevent
carbon monoxide or unburned gas from leaking into the room.
TO TEST FOR SPILLAGE:
1. Start all exhaust fans in the home, then close all doors and windows in the room.
2. Turn the appliance on and adjust to highest setting. Blower off.
3. Wait five minutes, then use a match or other device which creates smoke to test for a draft. Place the
match in front of the spill tube extension (you may want to place a piece of scrap steel or aluminum
foil) under the match to block the natural convection air supplied through the convection grill). The
smoke should be drawn into the spill tube extension. If it is not, wait five minutes and try again. If
there is still no draw, turn the unit off and check the venting for the cause. You may need to seek
expert advice.
NOTE: For high wind areas, the use of a high wind cap is recommended.
