WARNING! Risk of Fire or Explosion! DO NOT break silicone seals on slip sections. Use care when remov-ing termination cap from slip pipe. If slip section seals are broken during removal of the termination cap, vent could leak.
B. Assemble Slip Sections• Slidetheinnerflueoftheslipsectionintotheinnerflueofthepipesectionandtheouterflueoftheslipsectionovertheouterflueofthepipesection.SeeFigure7.5.
NOTICE: If slip section is too long, the inner and outer flues of the slip section can be cut to the desired length.NOTICE: When installing a vent system with an HRC termination cap, all pipe system joints shall be sealed using a silicone sealant with a minimum of 300 ºF (149 ºC) continuous exposure rating. • Apply a bead of silicone sealant inside the female outer
pipe joint prior to joining sections. • Only outer pipes are sealed, sealing the inner flue is not
required. • All unit collar, pipe, slip section, elbow and cap outer
• Secure the pipe and slip sectionwith two screwsnolongerthan1/2in.(13mm),usingthepilotholesintheslipsection.SeeFigure7.6.
