10 A. Vent 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 remainin...

12 a. Wipe 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 FULLY 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 Vertical Venting – 1. Do not exceed maximum vent lengths. Refer to Table 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 ...

28 1. Saf-T Vent 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 n...

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 assemblie...

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 affect the integrity of the seal. Install the system with the female ends (ends with the re...

33 11. Horizontal Supports: Saf-T Vent 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 ...

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. Support Legs Rotated Horizontally: Support legs can be use...

37 Vertical – 10. Installation of a vertical vent tee 8116304U 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. 11. Install fi re stops where vent passes through fl oors, c...

41 1. Do not exceed maximum vent/air intake lengths. Refer to Table 4. 2. This installation will allow a maximum of fi ve (5) feet vertical exterior run of the vent/air intake piping to be installed on separate horizontal venting and indoor air horizontal venting.

45 A. Design and install boiler and system piping to prevent oxygen contamination of boiler water and frequent water additions. 1. There are many possible causes of oxygen contamination such as:a. Addition of excessive make-up water as a result of system leaks. b. Absorption through open tanks and f...
