JOINT PROCEDURE
(see illustration #1 below)
1. The outside of male end and inside of female end of pipe must be cleaned before applying silicone
bead. Remove dirt, grease, and moisture from surface to be sealed. Dry surface or allow to dry
thoroughly.
2. Apply high temperature silicone approximately one half inch from end around male end of pipe and
along both sides of seam for one inch in an even 1/4” bead as per illustration #1.
3. Pipes can now be pushed together as far as they will go. The seams on pipes should be aligned and
oriented upwards in all horizontal applications. Apply another bead of silicone around this joint and
smooth out.
4. Tighten gear clamps (15 [N/LB. MAX.).
5. Check all joints and seams for tightness prior to using vent system.
6. Allow the sealant to cure for one hour before operating the appliance. Length of time required for full
cure depends upon thickness of application and other factors such as weather, ambient temperature,
humidity, etc. All sealants must be used within the time limitations marked.
