C. Assembling Flue Components
Insert the inner flue of section A into the flared inner
flue of section B.
Start the outer flue of section A over the outer flue of
section B (see Figure 21). Note: The end of the pipe
sections with the lances/tabs on it will face towards
the appliance.

Once both inner and outer flues are started, press
section A onto section B firmly until all lances have
snapped into place. Check to make sure they have
snapped together (see Figure 22) and the seams are
not aligned (see Figure 23). Tug slightly on section A
to confirm it has completely locked into place.

For elbows that are changing the flue direction, two
screws minimum should be put in the outer flue at the
joint to prevent the elbow from rotating.
