VENTING - BELOW GRADE USING FLEXIBLE DIRECT VENT SYSTEMS
INSTALLATION PROCEDURES FOR ARCHGARD SNORKEL KIT (Part #
NOTE: The Archgard Snorkel kit is designed for 4” x 7” (101 mm x 178 mm) flexible gas liners that are NOT supplied with the Snorkel Termination Head and MUST be ordered separately.
•If the Snorkel Termination is installed BELOW GRADE, (I.E. basement application) proper drainage must be provided to prevent water from entering the Snorkel Termination.
•Do not attempt to enclose the Snorkel in the wall or any other type of enclosure.
•For Snorkel Terminations ABOVE GRADE installations follow national or local code re- quirements.
1.Follow all other venting instructions in the manual regarding minimum vertical rise to hori- zontal runs, recommended pitch, and clearances to combustible materials.
2.Locate the centerline of the termination and mark the wall. Cut an 11” x 10” (279mm x 254mm) hole in the wall. NOTE: a 2” (50mm) x 1 ½” (13mm) around the 7” (178mm) liner is required. See Fig. 1 for termination framing.
3.Drill holes and insert the anchors as required.
4.Gently pull the coaxial vent through the hole. Apply a small bead of high temperature fur- nace cement around the 4” (101mm) collar on the snorkel and secure the 4” (101mm) flex vent with a stainless steel hose clamp and at least 3 screws. Make certain you have not pulled the vent too hard and accidentally disconnected it from the appliance.
5.Securely attach the 7” (178 mm) air intake pipe to the 7” (178 mm) collar on the snorkel kit with a 7” (178 mm) stainless steel hose clamp and three screws.
6.Apply a thick bead of all weather caulking all around the outside edges of the snorkel as- sembly and flanges.
7.Gently feed the vent back into the opening and push the snorkel up against the wall. Line up the holes previously drilled and lag the vent assembly to the wall.
8.Wipe off any excess caulking that squeezes out or add more to any areas that you may suspect will allow water to seep in.
