RFSDV24/34 Freestanding Direct Vent Gas Stove Below Grade Installations When it is not possible to meet the required vent terminal clearances of 12” (305 mm) above grade level a snorkel vent kit is recommended. It allows installation depth of down to 7” (178 mm) below grade level. The 7” is measured from the center of the horizontal vent pipe as it penetrates through the wall. If venting system is installed below ground, we recommend a window well with adequate and proper drainage.
RFSDV24/34 Freestanding Direct Vent Gas Stove Do not back fill around snorkel. A clearance of at least 4” (102 mm) must be maintained between snorkel and the soil. Max. 8’ (2.4 m) If the foundation is recessed, use recess brackets (not supplied) for securing lower portion of the snorkel. Fasten brackets to wall first, then secure to snorkel with self drilling #8 x 1/2 sheet metal screws. It will be necessary to extend vent pipes out as far as protruding wall face. (Fig.
RFSDV24/34 Freestanding Direct Vent Gas Stove Vertical Through-the-Roof Installation 1. Locate your stove. 2. Plumb to center of the 4” (102 mm) flue collar from ceiling above and mark position. 3. Cut opening equal to 9³⁄₈” x 9³⁄₈” (240 x 240 mm). 4. Proceed to plumb for additional openings through the roof. In all cases, the opening must provide a minimum of 1” (25 mm) clearance to the vent pipe, i.e., the hole must be at least 9³⁄₈” x 9³⁄₈” (240 x 240 mm). 5. Place stove into position. 6.
