H. Assembly of Centrotherm InnoFlue Vent Systems

6. Installations using InnoFlue Flex (Vent Options 20,21,37,38):

Warning

Asphyxiation Hazard. When using InnoFlue Flex, observe the following precautions:
• InnoFlue Flex may be damaged by handling at low temperatures. Do not bend, uncoil or attempt to

install if it has been stored at a temperature below 42°F without allowing it to warm to a higher

temperature first.

• Do not bend InnoFlue Flex more than 45°.

• Instructions below reference the Centrotherm InnoFlue instruction manual. Not all vent configurations

shown in the Centrotherm manual are approved for use with this boiler.

Refer to Centrotherm InnoFlue Instructions for assembly of all flex components including the chimney cap and the adaptor

to rigid InnoFlue at the base of the masonry or B vent chimney. In addition, observe the following requirements:

a. Refer to the appropriate Vent option in Tables 7.13b or 7.21 for a list of the principle flex components required. Rigid

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 options 20, 21) 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 Options 20, 21 are used, install a Tee of the same size at the base of the vent. Route the smooth section of

InnoFlue Flex (3”) or Flex Adaptor (2”) through a cap in the base of this Tee. Use a Centrotherm IAWP2P or 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 (2” or 3”, depending on the Vent Option). Cut a clearance hole in the cap for the male threads. Secure the adaptor

to the cap using a 2” or 3” electrical conduit lock nut. Seal all joints with RTV.
