10 A. V ent Guidelines Due to Removal of an Existing Boiler For installations not involving the replacement of an existing boiler , proceed to Step B. When an existing boiler is removed from a common venting system, the common venting system is likely to be too large for proper venting of the remaining appliances.
11 with at least one side open, similar to a joist bay application. Use double wall thimble [Burnham Part No. 81 16115 (3”), 100185-01 (4”)] when penetrating a combustible wall. 9. Do not install venting system components on the exterior of the building except as speci fi cally required by these instructions.
12 a. W ipe the male end of each joint using an alcohol pad to remove any dirt and grease. b. Align weld seams in pipes and use a slight twisting motion to FULL Y insert male end into female end of joint. Ensure bead in male end of pipe is below locking band and rest against the end of the female pipe.

17 V ertical V enting – 1. Do not exceed maximum vent lengths. Refer to T able 4. 2. Installation of a vertical vent tee 8116304U is required on all vertical vent applications. See Figures 6 and 7. Attach vertical vent drain tee directly to elbow or horizontal pipe from an elbow immediately after vent connector .
18 d. Install storm collar on air intake pipe immediately above fl ashing. Apply Dow Corning Silastic 732 R TV Sealant between air intake pipe and storm collar to provide weathertight seal. e. All exposed air intake piping must be constructed of corrosion resistant material such as aluminum, stainless steel or PVC.

28 1. Saf-T V ent SC is an advanced concentric vent system designed for zero clearance installation in residential applications. The inner wall is constructed from superferritic AL29-4C ® stainless steel. The outer wall is also constructed from stainless steel, providing durability and a lasting fi nish.
29 • For a venting system that extends through any zone above that on which the connected appliance is located (except for one and two family dwellings), the vent system shall be enclosed with an enclosure having a fi re resistance rating equal to or greater than that of the fl oor or roof assemblies through which it passes.
30 7. Joint Assembly Instructions: a. Before joining the sections or fi ttings together , use an alcohol pad to wipe the joint area of both ends of the inner pipe. This will remove any foreign matter which may af fect the integrity of the seal. Install the system with the female ends (ends with the red seal) pointing away from the appliance.
31 8. Straight Sections Cut T o Length: If a custom length of SC is necessary , a standard vent section can be cut. a. Measure the distance of the length needed, taking the measurement from the end of one of the outer jackets to the beginning of the other outer jacket on the section to connect to, (A to B on diagram).
32 9. Air Intake Connections for Dir ect V ent and Sealed Combustion Appliances*: The Air Intake T ee may be used on approved direct vent and sealed combustion appliances that have separate (non- concentric) air intake and fl ue exhaust collars.
33 11 . Horizontal Supports: Saf-T V ent SC must have supports for every six (6) feet of horizontal run and after every transition from vertical to horizontal. Support hangers by themselves do not maintain the necessary clearances to combustible materials; be sure to consider clearances when planning the system.
34 Support Clamp, (4_ _27SS): Support clamps are sold in pairs and can be clamped around the vent and suspended from a rod or cable. They can be used singularly as a saddle clamp to rest the vent in and suspended from two (2) rods or cables.
35 Fire Stop/W all Thimble/Support, (SC_ _FS): • The Saf-T V ent SC Fire Stop can be used as a fi restop, a wall thimble, or as a support plate. • T o use as a W all Thimble prepare an opening according to the chart below . Remove any insulation from the opening, using additional framing if necessary .
36 V ertical T erminations, (SC_ _VT): Install the vertical termination adapter into the last vent section and secure with the three (3) self-tapping screws provided. If the exhaust termination needs to be extended, a section of EZ Seal vent can be connected directly to the vertical termination adapter .
37 V ertical – 10. Installation of a vertical vent tee 81 16304U is required on all vertical vent applications. See Figure 6. Attach vertical vent drain tee directly to elbow or horizontal pipe from an elbow immediately after vent connector . 1 1. Install fi re stops where vent passes through fl oors, ceilings or framed walls.
