REqUIREMENTS
Installation of the provided vent restrictor as-
sembly is required for the venting configura-
tions listed in Figure 16-2.
The Vent Restrictor Kit (provided with the
fireplace; see Figure 16-1) includes one vent
restrictor base, two wings, and four screws.
1. Refer to Figure 16-2.
For venting configurations listed under
“Setting 1”:
Use the vent restrictor base only
(no assembly is required).
For venting configurations listed under
"Setting 2" or "Setting 3":
Use the four provided screws to attach
the two wings to the vent restrictor
base in the applicable position.
2. If the baffle and back panel are already
installed, remove them before proceeding.
See Page 26.
3. Install the vent restrictor assembly from
inside the firebox. With the
flaps
on the
vent restrictor base facing UP, carefully
bend the flaps inward just enough to slide
the assembly up into the vent collar, as
shown in Figure 16-3).
The vent restrictor is held in place by fric-
tion only.
The entire vent restrictor assembly must be
up inside the vent collar, with no portion
showing inside the firebox.
