When using an existing vent system to install a new boiler:

￿WARNING Failure to follow all instructions can result in flue gas spillage and carbon monoxide

emissions, causing severe personal injury or death.

Check the following venting components before installing:

•Material - For materials listed for use with this appliance, see Section 2 - General Venting. For polypropylene or stainless steel venting, an adapter of the same manufacturer must be used at the flue collar connection.

•Size - To ensure proper pipe size is in place, see Table 2A. Check to see that this size is used throughout the vent system.

•Manufacturer - For a stainless steel or polypropylene application, you must use only the listed manufacturers and their type product listed in Tables 2D and 2F for CAT IV positive pressure venting with flue producing condensate.

•Supports - Non-combustible supports must be in place allowing a minimum 1/4" rise per foot. The supports should adequately prevent sagging and vertical slippage, by distributing the vent system weight. For additional information, consult the vent manufacturer’s instructions for installation.

•Terminations - Carefully review Sections 2 through 4 to ensure requirements for the location of the vent and air terminations are met and orientation of these fit the appropriate image from the Sidewall or Vertical options listed in the General Venting Section. For stainless steel vent, only use terminations listed in Table 2F for the manufacturer of the installed vent.

•Seal - With prior requirements met, the system should be tested to the procedure listed in parts (c) through (f) of the Removal of an Existing Boiler Section on page 11.

With polypropylene and stainless steel vent, seal and connect all pipe and components as specified by the vent manufacturer used; with PVC/CPVC vent, see the Installing Vent or Air Piping Section on page 19.

If any of these conditions are not met, ￿ WARNING the existing system must be updated or

replaced for that concern. Failure to follow all instructions can result in flue gas spillage and carbon monoxide emissions, causing severe personal injury or death.
