C. Assembly of Crown Concentric Venting

WARNING

Failure to follow the instructions could result in flue gas leakage into the combustion air or indoor air, resulting in unsafe or unreliable operation.

•Do not lubricate concentric gaskets with anything other than water.

•Do not attempt to cut any piping except as permitted in this section. When cutting these sections, make sure all cuts are square and allow for proper insertion.

•Do not attempt to try to mix this concentric pipe with other venting systems.

1)The components listed in Table 1.6 are required for 80/125mm and 100/150mm installations and are not supplied with the BWC150/225 boilers. Before starting assembly of the vent system, make sure that the planned installation is in accordance with the “Vent System Design” section of this manual and that all required vent components are on hand. These components are available through Crown distributors.

2)Cutting Straight Pipe - The following straight pipe sections may be cut:
