Ensure any condensate is collected by strategically placing drains, or the appliance itself if permitted by the appliance manufacturer. 7

8 BOILER ADAPTER KITS (BKF and BKR) "C" Clamp Starter Section 90 DEGREE TEE (90T) When properly supported, the 90-Degree Tee will support 50 feet of vertical vent. This fitting is used to connect horizontal pipe runs into the vertical vent as well as a drain and/or inspection opening. Where access for a drain or an inspection opening is required, the following method for support can be used: Split Starter Ring Boiler outlet Figure 22 - Flanged Boiler Adapter For flanged appliance outlets, the Boiler Kit Flanged (BKF) should be used. The Boiler Kit Flanged consists of a split starter ring, starter section and the required number of "C" clamps for the installation. The Boiler Kit Flanged is installed in the following procedure: Apply a continuous bead of the proper sealant to the inner flange on one end of the Starter Section. Center the starter section on the boiler flange and place the two piece Split Starter Ring over the bottom flange on the Starter Section. Be sure that the tabs on the Split Starter Ring overlap and all parts fit snug. Place the required number of "C" clamps over the boiler flange and starter ring and tighten clamps. The flange can be field drilled to match the appliance outlet if desired. All other vent parts can now be installed (see joint assembly for the proper procedure). Figure Tees A. Suspended Tee - Support Plate or Wall Support at upper tee joint as shown in Figure 17. Raw end to connect to raw boiler outlet Rolled Flange to be connected to next section of pipe Figure 23 - Raw Boiler Adapter For a raw appliance outlets the Boiler Kit Raw (BKR) should be used. The Boiler Kit Raw consists of a collar type starter section. The Boiler Kit Raw is installed in the following procedure: Figure 25 - Suspended Tee B. Two axis support - This method is recommended if the total thermal expansion is expected to be above ¼ as shown in Figure Apply a continuous bead of the proper sealant to the inner flange of the appliance outlet. Place the starter section on the appliance outlet and tighten in place with the hardware provided. All other vent parts can now be installed (see joint assembly for the proper procedure). The boiler kits include a seal ring that will cover the gap between the inner and the outer shell. The seal ring clamps around the outer shell pipe and is held in place with (4) ¼ x 1 ½ bolts. Figure 25 - Two Axis Supported Tee 8

9 DRAIN TEE CAP (DTC) 90 DEGREE WYE (90Y) The Wye fitting is used when the vertical vent is located between two boilers and a low-pressure loss system is required. The Wye should be installed with the usual precautions observed for thermal expansions. Figure 26 - Drain Tee Cap The event, event Plus and event Plus2 has a 1" drain pipe that must be connected to a suitable drain. The eventsd has a 1/2" drain connection. The Drain Tee Cap must be connected at all times to a suitable drain. Upon entering the vent, rain will wash down and remove any corrosive combustible residue. The Drain Tee Cap must be installed with sealant at its mating surfaces with the flanged joint. This will ensure that moisture is drained through the drain as intended and will provide a tight seal. The Tee Cap can be installed for inspection access as required. 30, 45 AND 90 DEGREE ELBOWS (30L, 45L AND 90L) These elbows must be protected from the effects of thermal expansion. SUPPORT PLATE (SP) Figure 29-90Y The Support Plate offers the greatest strength for support of the event Series Venting System. It will provide vertical support and will provide for joint alignment and support for horizontal applications. Between any two fixed points in a system or whenever an adjustable length must be used to prevent the bending of tees and other fittings, locate and secure the Support Plate as necessary by means of structural ties to the building. The Support Plate must be secured to structural members of the building, which can adequately support the weight of the vent as shown on page 12 of these instructions. Figure 27-45, 30 and 90 Elbows 45 DEGREE LATERAL TEE (45LT) For venting systems that require a 45 degree entry to the vertical vent, the 45 Degree Lateral Tee (45LT) may be used. The 45 Degree Lateral Tee should be supported in the same way as the 90 Degree Tee. When properly supported, the 45 Degree Lateral Tee will support 50 feet of vertical vent and may be installed with a Drain Tee Cap or End Cap. Figure 30 - Support Plate Attachment The Support Plate consists of a split clamp flange, split plate and necessary hardware. The split clamp flange and the split plate are used to clamp the inner flanges together and are turned 90 degrees apart. The notches in the split plate and in the clamp flange are to accommodate the inner band end clips, allowing the "V" to rest solidly on the split plate. The installation procedure is as follows: Figure Lateral Tee Connect the joint to be supported by use of the inner band as previously discussed. Connect the split clamp flange to the split plate with the provided hardware. The split plate should be below the finished joint and the clamp flange should be above the finished joint. 3/8 x 1 ½ bolts should be used in all of the inner clamp flange holes. Tighten all bolts. Install the special outer bands provided and seal with sealant. 9

10 Proper performance and long service life of the Model event Series Venting System requires that the vent be rigidly braced and supported. Every installation offers unique support and bracing requirements and the following guidelines will provide minimum acceptable sizes for the mechanical hardware supplied by others. When the support plate is bolted to framework 3/8 bolts should be used in all of the holes on the perimeter of the support plate. event Series Size Framework Bracing 4" - 20" 2 x 1 x 3/16 to 5 x 2 x 2 x 2 x 3/16 3/16 or equivalent 22" - 36" 5 x 2 x 3/16 to 6 x 2 x 3 x 3 x 1/4 3/16 or equivalent 38" - 48" 6 x 2 x 3/8 or equivalent 4 x 4 x 3/8 The Wall Support is intended for attachment to non-combustible structures. When attached, the Wall Support provides a fixed point in the vent system. Install a Variable Length below a Wall Support to provide the necessary expansion compensation. The Wall Support, when properly installed, will allow for the required clearances to combustibles along the wall and will support the length of pipe outlined on page 12 of these instructions. WALL GUIDE (WG) The wall guide is used to protect the vertical vent from lateral wind loads and to allow for thermal expansions. When assembled, the proper installation location is at a joint but below the outer band. The outer wall of the vent must be able to move away from the outer ring of the wall guide. When properly attached to a combustible wall, the Wall Guide will maintain the proper clearances to combustibles. Wall Guides should be equally spaced along the wall at spacings no greater than 16 for 4 through 10 diameters and 24 for 12 through 48 diameters. WALL SUPPORT (WS) Figure 31 - Support Plate Bracing The Wall Support consists of two split plates, brackets and all necessary hardware. The notches in the split plates on the Wall Support are to accommodate the inner band end clips, allowing the "V" to be clamped between the split plates. Installation for the Wall Support is accomplished with the following procedure: Figure 33 - Wall Guide Connect the joint to be supported by use of the inner band as previously discussed. Connect the split clamp flange to the split plate with the provided hardware. The split plate should be below the finished joint and the clamp flange should be above the finished joint. 3/8 x 1 1/2 bolts should be used in all of the inner clamp flange holes. Tighten all bolts. Bolt the wall brackets to the split plate assembly with the (6) 3/8 x 1 ½ bolts as provided. Locate and bolt the entire assembly to the wall with (8) ½ dia. bolts. Apply sealant around outer Half Bands and support plate for exterior installations. CAUTION: Always maintain proper clearances to combustibles when installing all guides and supports. Keep all insulation away from required clearance (air) spaces surrounding the vent. Guides and supports are only suitable for attachment to noncombustible construction due to possible heat conduction. FLOOR ROOF GUIDE (FRG) Floor Roof Guides are used to provide lateral support for the vent in the roof and floor opening. The Floor Roof Guide is to be bolted to non-combustible construction in (4) four places. Figure 34 - Floor Roof Guide Figure 32 - Wall Support 10

11 FULL AND HALF ANGLE RINGS (FR AND HR) The full and half rings are used to guide the vent either vertically or horizontally. The rings should be placed at intervals shown in the chart below and securely connected to the building structure. The diameter of the Full Ring is slightly larger than the pipe. This will allow the pipe to slide within the ring. This movement must be allowed to compensate for thermal expansion. INSULATED THIMBLE (IT) The insulated thimble is used in conjunction with the flashing and rain collar when clearances to combustibles cannot be maintained at a roof penetration. The Insulated Thimble should be dropped through the roof opening. The (4) four tabs will set upon the roof deck and nailed or bolted down. The flashing is then set over the Insulated Thimble. event Series Horizontal Support Spacing eventsd When Terminating Horizontally Up To 6' eventsd When Terminating Vertically Up To 8' Event, eventplus & eventplus2 Up To 12' event Series Vertical Guide Spacing All event Series Diameters 5" to 10" Up To 16' All event Series Diameters 11" to 48" Up To 24' RAIN CAP (CC) Figure 37 - Insulated Thimble Figure 35 - Full Ring and Half Ring FLASHING AND RAIN COLLAR (FL AND RC) The Rain Cap provides partial protection from rain and debris. The Rain Cap is mounted on the end of a standard pipe section with the use of a inner band. A closure ring is provided to close off the space between the inner and outer liners. A minimum clearance of 8 feet (2.44 m) is recommended to ensure that all exhausted products are dispersed away from the building and intakes. To install the Rain Cap, the following procedure should be used: Both the Flashing and the Rain Collar are designed to fit the outside of the Model event Series Venting System. They are constructed of galvanized steel and should be protected from corrosion by cleaning and painting. The Flashing is nonventilated and for non-combustible and combustible flat roofs. Flashings of a special pitch are available upon request. The Flashing should be protected from lateral movement of the stack by use of the Full Ring or the floor/roof Guide Apply a bead of the proper sealant to the flange of the inner pipe to receive the Rain Cap. Place the Rain Cap on the existing inner flange and attach the "V" band as previously mentioned. Install the provided collar as shown. Apply a silicon sealant to fill any gaps and joints on the collar and tighten all bolts. The Rain Collar is secured around the pipe immediately above the flashing and should be sealed with a silicone sealant. Figure 36 - Roof Penetration Figure 38 - Rain Cap Assembly 11

12 To clean the flue or replace the Rain Cap, reverse the above procedure. To reinstall, follow the installation procedure. TOP SECTION (TS) The Top Section is installed using the same procedures as a Rain Cap (CC). Figure 39 - Top Section EXIT CONE (EXC) The Exit Cone is installed using the same procedure as the Rain Cap (CC). Figure 42 Rigid Guying Angle GUY SECTION (GS) Figure 40 - Exit Cone When the height above the roof line exceeds 12 feet, a Guy Section is recommended. The inner flanges of the Guy Section are connected in the same procedure as the typical pipe sections. The outer shell is then sealed by using special half bands and sealant. Guy wires or braces are to be attached to the horizontal flanges of the Guy Section (See Figure 35). The cables and pipe guys must be slightly loose to allow for thermal expansions. To reduce the thermal expansion effects on rigid bracing or guy wires, a Support Plate (SP) or Wall Support (WS) may be installed at or below the roof line. Guy tensioners may be required if the thermal expansion exceeds the allowable slack in cables. Figure 43 Bracing Requirements Figure 41 - Guy Section Figure 44 Maximum Freestanding Height 12

13 LIMITATIONS MAXIMUM HEIGHT ABOVE TOP LATERAL BRACE OR GUY Vent Inside Diameter Maximum Height 4-10 ( mm) 8 feet (2.44m) ( mm) 12 feet (3.66m) If the height above the roof line is less than that specified above, no guying or bracing is required. However, a Insulated Thimble (IT), Floor/Roof Guide (FRG) or Full Ring (FR) at the roof line is necessary to protect the Flashing (FL) from side loads caused by wind. For heights above the roof line greater than that shown above, the vent must be guyed or braced. Guying or bracing is accomplished by use of the Guy Section (GS) Full Ring (FR) or Wall Guide (WG). Guy wires or braces are to be attached to the horizontal flanges of the Guy Section. While 3 guys are usually sufficient, it is recommended that 4 equally spaced wires at an angle of 45 from the vertical be utilized. The cables and guys must be slightly loose to allow for the thermal expansion. Rigid bracing requires two braces with not less than 60 angle between them. The braces must be attached to a Guy Section (GS) or Full Ring (FR). DRAIN TEE CAP (DTC) DRAIN SECTION (DS) Figure 45 - End Cap The drain tee cap is installed exactly the same as the end cap.

The end cap is installed by connecting the inner cone to the adjacent pipe section with a inner band and sealant. The outer cover piece is then fitted over the outer shell and bolted into place with (2) ¼ x 1 ½ stainless steel bolts. Whenever the end cap is removed for inspection purposes the flanges must be cleaned and resealed when reinstalling the part. Figure 47 - Horizontal Drain 13

14 OPERATING PRECAUTIONS A licensed or qualified vent sweep should be contacted to clean the vent. Contact local building or fire officials about restrictions and installation inspection in your area. MAINTENANCE Venting and Exhaust Systems 1. After the installation of the vent or exhaust system, ensure that the required clearances are maintained and For tee caps, adequate clearance is required around clean-outs to assure accessibility for removal of caps and products accumulated within the vent. 2. that the system continues to be supported properly. The venting system should be inspected if there is any evidence of damage to the vent system, and at least annually, for internal deposits, soundness and correct clearances. Cleaning and repairs shall be as needed. It is recommended that exterior mounted venting systems located in geographical areas which experience sustained low ambient temperatures be enclosed to reduce or limit condensation, creosote buildup and poor draft Caulking on exterior portions of the vent, flashing, rain collar, etc. should be inspected and repaired or replaced as needed to prevent leakage. Painted portions of the vent shall be cleaned and touched-up or repainted as required to prevent corrosion. Supports, guys, braces, etc. should be inspected at least annually to make sure bolts are tight. For further information see NFPA 211, latest edition, chapter titled Maintenance. 14
