WARNING: This appliance has been designed to draw room air for proper heat circulation
from the sides of the unit. Blocking or modifying the louvers in any way can create hazardous
situations.
The vent length for the EG31 must be between 8ft (2.44 m) and 25ft (7.62 m).
This model is vented with TWO (2) 3” aluminum or stainless steel flex vent leading into a co-linear to co-
axial vent adaptor and using a Simpson Dura Vent vertical termination cap. The flue collars of this model
will fit inside of standard 3” vent and may be fastened directly to the vent. The Exhaust vent is in the
center of the flue connector. The Air Intake is on the left side of the vent collar plate (this outlet is not in
the center it is off to one side of the vent collar plate.)
Check periodically that the vents are unrestricted. Also ensure that all direct vent pipes have been
properly sealed and installed after routine inspection or cleaning. The air intake and exhaust pipes must
be installed in the correct locations on the removable draft hood connector.

An approved chimney liner and rain cap must be used. A throat connector or flashing must be installed to
ensure a tight seal, top performance, safety and efficiency. Carefully follow the manufacturer’s instructions
that accompany the chimney liner kit. Use double walled aluminum flex vent (3” flex conversion piece and
4”x 6 5/8” cap) from any of the following approved products; Simpson Dura-Vent (Direct Vent GS) or (ICC
Excel Direct). If necessary, remove the vent collar plate from the top of the insert and connect it securely
to the liner with sheet metal screws.
Check for any tears in the liner at this point. IMPORTANT: The screws that hold the vent collar plate in its
approved position must be installed.
NOTE:
If the EG31 unit is pulled out of its installation, and the vent air intake system is disconnected
for any reason, ensure that the vent-air intake pipes are re-sealed with high-temperature sealant and
reconnected with three (3) sheet metal screws evenly spaced.
