Installation & Operation Manual

1 Determine boiler location (continued)

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 3 - General Venting, Table 3A. For stainless steel venting, an adapter of the same manufacturer (Table 3B) must be used at the flue collar connection.

•Size - To ensure proper pipe size is in place, see Table 3D. Check to see that this size is used throughout the vent system.

•Manufacturer - For a stainless steel application, you must use only the listed manufacturers and their type product listed in Table 3A 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 3 through 5 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 3B 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 12.

With 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 17.
