10. The next step is to install the vent starter pipe onto the
fireplace.
11. Remove the glass panel and glass frame assembly from
the front of the firebox by loosening and removing the four
glass frame fasteners that are located along the top edge
of the glass frame.
12. While holding the glass panel and glass frame along the
outer edges, tip the top of the glass frame forward a few
inches.
13. Wrap your fingers around the frame and hold the glass and
frame together while you lift the frame up and out of the
lower glass retainer. Set the glass and frame assembly
aside in a safe place.
14. Carefully place the fireplace with the front down on a
protected floor.
15. At this point, it is necessary to determine whether your
installation will require the addition of flow restrictors to the
combustion air inlet system or the exhaust outlet or both.
Refer to the venting section that starts on page 8 to
make that determination.
16. If your installation does not require any restrictors, place
the vent starter pipe gasket on the back of the fireplace
aligning the holes in the gasket with the pilot holes on
the rear of the fireplace.
17. Align the inner pipe of the vent starter pipe with the
exhaust outlet pipe on the fireplace. The vent pipe will fit
tightly over the fireplace pipe. Gently push the starter
pipe on to the fireplace pipe until the outer pipe flange
makes contact with the starter pipe gasket. Be sure that
the holes in the starter pipe flange align with the gasket
and pilot holes. When the flange contacts the gasket,
install the four fasteners provided with the starter pipe.
18. If your installation does require an air restrictor or
exhaust restrictor or both, these must be installed before
you install the vent starter pipe. Again, refer to the
venting information starting on page 8 to determine
the specific restrictor requirements for your specific
installation.
19. The exhaust restrictor is installed by placing it through
the exhaust outlet pipe and resting it on the internal
baffle in the firebox. It is held in place with a movable
retainer clip. Simply hold the restrictor down against
the baffle and push the retainer up and tighten screw
to secure the restrictor. Note: Please take care to
insure that the exhaust restrictor is centered in the
exhaust outlet. Improper alignment could adversely
affect the appearance of the flames. Refer to the
adjacent illustrations for placement of the exhaust
restrictor and clip.
