STEP 5
Tape the inner and outer flue collars of the fireplace
using UL approved metal adhesive tape to ensure the
joints are sealed. Attach an appropriate length of vent
pipe to the fireplace. Follow with the installation of the
inner and outer elbow, tape elbow joints and secure
joints as described on Page 13.

Measure the horizontal length requirement including
a 2" (50 mm) overlap, ie from the elbow to the outside
