Venting; Gas Supply - Pacific energy Brentwood Gas Insert Installation And Operating Instructions Manual

Venting

Caution: Use only a flue liner system approved by the
local gas authority and install in accordance with the
manufacturers instructions. Consult local and/or national
building codes before altering fireplace.
The chimney must be relined with a minimum 4" flue liner
(Fig. #7). A combination of 4" flex and rigid flue liner may be
used. (Consult local codes) The liner should extend from the
Insert collar to the top of the chimney. At the top of the
chimney, the air space between the new liner and existing
chimney must be sealed to prevent water from entering. Place
a flashing that fits snugly around the 4" liner on top of the
chimney. Caulk the flashing in place to seal any gaps.
Remove the screw located in front of the vent connector plate.
Attach the flex end of the flue liner to the collar on top of the
connector plate.

Gas Supply

Caution: The gas line should be installed by a qualified
service person in accordance with all building codes.
Consult local and/or national building codes before pro-
ceeding.
The gas valve inlet accepts a 3/8" N.P.T. fitting. Correct gas
line diameter must be used to assure proper operation.
The gas control is equipped with a capture screw type pres-
sure test port, therefore it is not necessary to provide an 1/8
inch N.P.T. plugged tapping pressure port for checking gas
pressure immediately upstream of the gas supply connection
to the appliance.
A knockout is provided at the bottom right rear of the
appliance as an alternate inlet for a gas supply line (Fig. #8).
To use this inlet, remove the knockout from the rear of the
appliance. Remove the plastic bushing installed in the side
and reinstall into the hole at the rear of the appliance.
An optional 24" long flexible connector (part #
GASC.GASCON) may be used for easy gas connection. This
connector may exit the appliance through either the right
front or right rear access holes.
