WARNING! Risk of Fire or Explosion! Use vent run supports per vent manufacturer’s installation instructions.

•Connect vent sections per vent manufacturer’s installation instructions.

D. Install Attic Insulation Shield

WARNING! Fire Risk. DO NOT allow loose materials or insulation to touch vent. Hearth & Home Technologies Inc. requires the use of an attic shield.
