PART IDENTIFICATION
This vent is to be installed unenclosed or with enclosures. If the vent passes through any zone or story of a building above that on which the connected appliance is located, it is to be enclosed in construction having a fire rating equal to or greater than that of the floor or roof assemblies through which it passes. NOTE: Always check with the Authority Having Jurisdiction for material with an appropriate fire rating. If a portion of the vent passes between a dropped ceiling and roof, that portion is to be enclosed in a fire rated enclosure or proper clearance to combustibles are maintained. Vents are not intended to pass through combustible walls. Any wall through which the vent passes must be of non-combustible construction unless proper clearance to combustibles are maintained.
Clearances to non-combustibles shall be necessary for installation, inspection and maintenance.

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 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.
Figure 30 - Support Plate Attachment
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.
45 DEGREE LATERAL TEE (45LT)
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.
DRAIN TEE CAP (DTC) 90 DEGREE WYE (90Y)
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.
These elbows must be protected from the effects of thermal expansion.
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 29 - 90Y
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.
SUPPORT PLATE (SP)
3/8” x 1 ½” bolts should be used in all of the inner clamp flange holes. Tighten all bolts.

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 32 - Wall Support
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.

INSULATED THIMBLE (IT)
Apply a bead of the proper sealant to the flange of the inner pipe to receive the Rain Cap.
The Rain Collar is secured around the pipe immediately above the flashing and should be sealed with a silicone sealant.
Install the provided collar as shown.
Figure 36 - Roof Penetration
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 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.
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 non-ventilated and for non-combustible and combustible flat roofs. Flashings of a special pitch are available upon request.
RAIN CAP (CC)
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.
FULL AND HALF ANGLE RINGS (FR AND HR)
Place the Rain Cap on the existing inner flange and attach the "V" band as previously mentioned.
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:
The Flashing should be protected from lateral movement of the stack by use of the Full Ring or the floor/Roof Guide.

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.

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).

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.
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.
For tee caps, adequate clearance is required around clean-outs to assure accessibility for removal of caps and products accumulated within the vent.
For further information see NFPA 211, latest edition, chapter titled Maintenance.
OPERATING PRECAUTIONS
Supports, guys, braces, etc. should be inspected at least annually to make sure bolts are tight.
After the installation of the vent or exhaust system,
ensure that the required clearances are maintained and
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.
Painted portions of the vent shall be cleaned and touched-up or repainted as required to prevent corrosion.
MAINTENANCE
Caulking on exterior portions of the vent, flashing, rain collar, etc. should be inspected and repaired or replaced as needed to prevent leakage.
