Masonry Fireplaces
A solid-fuel fireplace chimney must be clean and in
good working order. It must be constructed of no-
combustible materials. Chimney clean-outs must fit
properly.
When installing the Universal GI 350 DV gas
insert into a masonry fireplace, the insert will be
vented through dual 3” flexible gas aluminum liners.
This co-linear installation includes a pair of 3”
flex ducts that run from the insert completely
through the existing chimney to the termination cap.
One liner is attached to the Exhaust Outlet on
the back of the unit and will carry the exhaust gases
to the outside of the house. This exhaust liner must
be directly connected to the unit and run the full
length of the chimney. See fig. 6.
The other 3” liner will be attached to the Air
Intake Collar on the back of the unit to provide fresh
air for combustion. The Intake Collar is labeled for
easy identification. The liner must extend a mini-

through the damper area of the fireplace into the tile
liner of the chimney. This liner can also extend the
full length of the chimney and connect to the
termination cap.
IMPORTANT
If the intake flex does not extend the full length
of the chimney, forming a direct connection between
the unit and the termination cap, A METAL BLOCK
OFF PLATE MUST BE INSTALLED to seal the air intake
from room air. Normally this sealing plate will be
installed within the existing fireplace damper area.
See fig. 6. The sealing plate is not necessary if a direct
connection is made between the cap and the fire-
place. W

Before installation, label both ends of the exhaust flex

Cutting of any sheet metal parts on a solid-fuel
fireplace is prohibited.
