system designed for zero clearance installation in residential applications. The inner wall is constructed from superferritic AL29-4C steel. The outer wall is also constructed from stainless steel, providing durability and a lasting fi nish. 2. As a Special Gas Vent system: Saf-T Vent is approved for use on ANSI Category I, II, III, and IV Gas-Burning Appliances and certain Direct Vent Appliances.

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 red seal) pointing away from the appliance.
Page 31
8. Straight Sections Cut To 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).

9. Air Intake Connections for Direct Vent and Sealed Combustion Appliances*: The Air Intake Tee may be used on approved direct vent and sealed combustion appliances that have separate (non- concentric) air intake and fl ue exhaust collars. The male end of the tee connects to EZ Seal appliance adapters and the tee takeoff/snout connects to the appliance air intake.
Page 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 the system.
Page 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 used on horizontal runs by rotating the clamp at the rivet connection.
Page 35
Fire Stop/Wall Thimble/Support, (SC_ _FS): • The Saf-T Vent SC Fire Stop can be used as a fi restop, a wall thimble, or as a support plate. • To use as a Wall Thimble prepare an opening according to the chart below. Remove any insulation from the opening, using additional framing if necessary.
Page 36
Vertical Terminations, (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. Seal weather exposed joints of the outer jacket with foil tape or an exterior grade silicone sealant.

2. Maintain minimum ¼ inch per foot slope in horizontal runs. 3 Recommended horizontal installation consists of vent being sloped down away from boiler. See Figure 12. 4. Slope horizontal runs minimum ¼ inch per foot. Slope towards vertical vent drain tee. Position weld seams in vent pipes, in all horizontal runs, at the top to avoid condensate from lying on the seams.

. If a low water cutoff is required, it must be mounted in the system piping above the boiler. The minimum safe water level of a hot water boiler is just above the highest water containing cavity of the boiler; that is, a hot water boiler must be full of water to operate safely.
Minimum gas valve inlet pressure is stamped on the rating label located in the boiler’s vestibule compartment. 2. Maximum gas demand. Refer to the boiler’s input as printed on it’s rating label. Also consider existing and expected future gas utilization equipment (i.e.
