Vermont Casting RAD- VTBB Vent Termination Below Grade, Vertical Through the Roof Vent Assembly

11.For CFM only: Install Charcoal Gray Pipe Rings (#7FSDRG) or Polished Brass Pipe Rings (#7FSDRP) at pipe joints, if desired.

Vent Termination Below Grade

Install Snorkel Kit #7FSDVSKS when it is not possible to meet the required vent termination clearances of 12” (305 mm) above grade level. The snorkel kit will allow installation depth of down to 7” (178 mm) below grade level. The seven inches is measured from the center of the horizontal vent pipe as it penetrates the wall. If the venting system is installed below grade, a window well must be installed with adequate and proper drainage. (Fig. 31)

NOTE: Be sure to maintain side wall clearances and vent run restrictions. Refer to Page 6, Figures 3, 4, 5, 6.

1.Establish the vent hole through the wall.

2.Remove soil to a depth of approximately 16” (406 mm) below the base of the snorkel. Install a window well (not supplied). Refill the hole with 12” (305 mm) of coarse gravel and maintain a clearance of at least 4” (102 mm) below the snorkel. (Fig. 31)

3.Install the vent system as described on Pages 16-18.

4.Be sure to make a watertight joint around the vent pipe joint at the inside and outside wall joints.

5.Apply high temperature sealant around the inner and outer snorkel collars. Join the pipes and fasten the snorkel termination to the wall with the screws provided.

6.Level the soil to maintain a 4” clearance below the snorkel.

If the foundation is recessed, use extension brack- ets (not supplied) to fasten the lower portion of the snorkel. Fasten the brackets to the wall first, and then fasten to the snorkel with self-tapping #8 x 1/2” sheet metal screws. Extend the vent pipes out as far as the protruding wall face. (Fig. 31)

Vertical (Through the Roof)

Vent Assembly

Make certain the vent system conforms to all other requirements for vertical termination as specified on Page 9.

This installation will require you to first determine the roof pitch and use the appropriate vent components. Refer to Figure 11 on Page 10.

1.

Locate the final position of the stove, observing all

 

clearances for both the vent and the stove.

2.

Plumb to the center of the inner (4”) flue collar from

 

the ceiling above, and mark that location.

3.

4.

Plumb any additional opening through the roof or

 

other construction that may be needed. In all cases,

 

the opening must provide a minimum of 1” (25 mm)

 

clearance to the vent pipe.

5.

Place the stove in its final position.

6.

Install firestop(s) #7DVFS and Attic Insulation Shield

 

#7DVAIS as needed. (Fig. 32) If there is a room

 

above ceiling level, a firestop must be installed on

 

both the bottom and top sides of the ceiling joists.

 

If an attic is above ceiling level, an attic insulation

 

shield must be installed.
