vent pipe by the same manufacturer will also be required for the run from the boiler to the base of chimney.
b. Masonry chimneys cannot be used for an air chase
c. B vent chimneys can only be used for an air chase (Vent option 10) if the B vent has the minimum size shown in Table
7.13b and is fully accessible for sealing of all joints and seams.
d. When Vent Option 10 is used, install a Tee of the same size at the base of the vent. Route the smooth section of InnoFlue
Flex (3”) through a cap in the base of this Tee. Use a Centrotherm IAWP03B wall plate and RTV to seal this penetration.
Install the Base Support using the Base support bracket as described in the InnoFlue installation manual.
Connection of the PVC air intake pipe to the side outlet of the tee is made using a cap and a PVC socket x male thread
adaptor. Cut a clearance hole in the cap for the male threads. Secure the adaptor to the cap using a 3” electrical conduit
lock nut. Seal all joints with RTV.
