Chlorine found usually in the form of freon or degreaser vapors, when exposed to flame will precipitate from the compound, and go into solution with any condensation that is present in the heat exchanger or associated parts. The result is hydrochloric acid which readily attacks all metals including 300 grade stainless steel. Care should be taken to separate these vapors from the combustion process. This may be done by wise location of the combustion air terminal with regard to exhausters or prevailing wind directions. Chlorine is heavier than air. Keep these facts in mind when determining installation location of the heater in relation to building exhaust systems. Form I-UD-V-SC,Page 2 1,1 Type of Pipe All pipe is field supplied.

Instructions Select a location away from fresh air intakes, allowing space for the for Vertical Vent/ concentric adapter box inside. Vent terminal must be located from adjacent Combustion Air buildings as shown in FIGURE 17, page 16. Kit (Option CC2) WARNING: All vent terminals must be positioned or located away from fresh air intakes, doors and windows to preclude combustion products from entering occupied space. Failure to comply could result in severe personal injury or death and/ or property damage. If more than one vertical concentric vent/combustion air terminal (Option CC2) is being installed, the minimum spacing between vent centerlines is determined by the minimum outdoor design temperature (most extreme outdoor condition at the installation site).

Length must comply with Requirement 1.3, pages 3-4. Seal all joints. Due to the high temperature, do not enclose the exhaust pipe or place pipe closer than 6" (152 mm) to combustible material. Provide supports for the pipes. Extend the runs to close to the roof at the location selected in Step 1. 3) Prepare a clearance hole through the roof for the combustion air pipe -- a 6" (152mm) diameter pipe for Sizes 30-125 or an 8" (203mm) diameter pipe for Sizes 150-400. A thimble may or may not be required depending on building construction and/or local codes. The larger diameter combustion air pipe serves as clearance for the vent pipe on non-combustible construction. 4) Prepare the Concentric Adapter Box a. Attach the brackets to the box. Follow the instructions in FIGURE 13.

Do not extend it more than 6" (152mm) below the box. b. Install the pipe. Being sure the pipe is in the proper flow direction, slide the end into the box and out through the combustion air pipe. Position the vent pipe so that the end is no more than 6" (152mm) below the box. The upper end should extend at least 3" (76mm) above the combustion air pipe. NOTE: The double-wall vent pipe does not attach to the box. The installer must provide support. Follow the instructions in FIGURE 3, page 5, for connecting the double-wall pipe to the Category III pipe or taper-type connector. Seal the circumference of the pipe and the opening of the box with silicone sealant. Seal the area around the pipe completely. 7) On the outside, if an additional section of double-wall pipe is needed (See FIGURE 16), add it. Make joint according to the pipe manufacturer's requirements. When vent pipe is the required height, slide the combustion air inlet over the vent pipe and fasten the collar to the combustion air pipe with sheetmetal screws. See FIGURE 16.
