COMPLETE ASSEMBLY

DuraVent DirectVent Pro  GENERAL MAINTENANCE

Conduct an inspection of the venting system annually. Recommended areas to inspect are as follows:

1. Check areas of the Venting System which are exposed to the elements for corrosion. These will ap

-

pear as rust spots or streaks, and in extreme cases, holes. These component should immediately be 

replaced.

2. Remove the Vertical Termination Cap and shine a flashlight down the Vent. Remove any bird nests, 

or other foreign material.

3. Check for evidences of excessive condensation, such as water droplets forming in the inner liner, 

and subsequently dripping at joints. Continuous condensate can cause corrosion of caps, pipe, and fit

-

tings. It

may be caused by having excessive lateral runs, too many elbows, and exterior portions of the system 

being exposed to cold weather. 
4. Inspect joints to verify that no Pipe Sections or Fittings have been disturbed or loosened. 

Also check mechanical supports such as Wall Straps or plumbers tape for rigidity.

Pipe Sections and the insulation or other debris. For the Attic Insulation Shield, nail the base to floor of 

attic and adjust shield for appropriate insulation level, then attach the collar at the top of assembly (Fig. 

19). For a chase enclosure, it may be constructed out of sheetrock or similar building materials and 

framed around the support box or the pipe, maintaining the 1" clearance to combustibles as required 

by the appliance manufacturer. For vaulted ceilings a chase enclosure must be constructed as the Attic 

Insulation Shield can not be installed.
