The system can now be assembled through the thimble (attach the termination first - note “UP” arrow) and then back to 

the appliance as per illustration using 

JOINT PROCEDURE

 as described on page #3. A gear clamp (or locking band) must 

be installed around the pipe on the inside of wall to trap pipe in position so that the system cannot be moved in or out of 

wall (see images 4 & 5). This applies to both combustible and non-combustible walls

3.

 

The system must be supported along its horizontal length at all elbow locations (see illustration 2 below) and joints (every 

forty-eight inches or less) using straps around pipes maintaining clearance to combustibles as per table on page 3. 

  

4.

 

The horizontal distance of the system from the appliance flue collar to the outside of the horizontal termination cannot be 

greater or less than that specified in the appliance manufacturer’s installation instructions.  Any horizontally installed portion 

of a venting system shall have a slope (upwards for Category II, III, or IV appliances or downwards for Category III or IV 

appliances) not less than 1/4” (6.4 mm) every 12 inches (305 mm) to prevent collection of condensate at any location in the 

assembly. 

Fasteners must not penetrate the components of the system either when joining pipes and fittings 

or using support straps.  Drilling holes in the vent components is not permitted.

 

 

 

The lengths of pipe may be cut on non-expanded end using aviation snips or a hacksaw (24 tpi).  Make certain to keep the cut end 

cylindrical.  The cut end must be filed or sanded smooth before joining (see images 6 & 7). 

i)

 

Measure 2 inches from cut end and draw a line to indicate depth insertion. 

ii)

 

Insert male end into female end to within ¼ inch of the drawn line to achieve full depth insertion.

When installing the condensate tube be sure to form a trap by means of a 3 inch (76.2 mm) loop filled with water. This tube must 

be 3/8 inch ID high temperature silicone for at least the first 6 inches (152 mm) and attached with a gear clamp or hose clamp (see 

image 8 & 9). The effluent must be disposed of according to local regulations. 

 

NOTE

: Z-FLEX recommends using a neutralizer kit when using a condensate trap. A condensate pump may be required.
