3.  Do not allow the fl exible vent to bend in radius tighter than 5" (127mm). Refer to Figure 2. 

  4. 

Horizontal 

runs 

of 

fl exible vent shall be supported at maximum 2 foot intervals; vertical runs, fi ve feet  

 

 

 

intervals. Metal strapping, properly secured, is an acceptable means to support the fl exible vent. 

 

 

5.  Flexible vent spacers are to be installed at intervals prescribed by the fl exible vent manufacture; and in such a   

 

 

way as to maintain concentric inner and outer vent spacing.  

 D. 

Attaching 

fl exible venting to vertical termination assemblies.

 

 

1.  When using Simpson pipe, a MHS fl ex-to-pipe adaptor and/or rigid pipe section(s) is required to connect the    

 

 

fl exible vent assembly to the vertical termination by using three self penetrating screws. 

  2. 

Review 

Figure 4 and corresponding instructions for proper overlap, clamp and screw placement.

 

 

3.  Three each self penetrating screws are drilled opposite one another and below the gear clamp. 

 

 

4.   Use only listed and approved terminations and accessories, installed per the installation instructions and  

 

 

 

 E. 

Installing 

fl exible venting to horizontal termination assemblies. 

  1. 

Connect 

the 

4" 

fl exible vent to the horizontal termination as in Figure 5.

 

 

2.  Slide termination cap adapter ring over the termination cap’s outside pipe and secure with three screws.

  3. 

Connect 

the 

7" 

fl exible vent to the termination adapter ring as in Figure 5.

  4. 

Review 

Figure 5 for proper overlap and clamp placement

 

 

5.  Three each self penetrating screws are drilled opposite one another and below the gear clamp. 

 

 

6.  Use only listed and approved terminations and  

 

  

 

 

accessories, installed per the termination instructions  

  and
