and outer flue collars of the fireplace and using ap-
propriate venting component(s) attach to fireplace with

STEP 6
NOTE: If using charcoal wall plate Pt. #10000257,
and collar Pt. # 52203-CG, put them in place before
putting the pipe sections through the wall.
Use appropriate length of pipe sections - telescopic or
fixed - and install the horizontal vent sections. The sec-
tions which go through the wall are packaged with the
starter kit, and can be cut to suit if necessary. (Fig. 18)
Sealing vent pipe and firestop gaps with
high temperature sealant will restrict cold
air being drawn in around fireplace.
