Step-By-Step Installation For Flex DV Kit

1.Unpack vent components and check all items for shipping damage.

2.For this venting system to operate as designed it is depen- dent on the use of all parts and procedures detailed in these instructions. Failure to follow these instructions may poten- tially affect the performance of this vent system and the at- tached appliance.

3.As per the fireplace manufacturer’s instructions, replace the existing 6 5/8” diameter fireplace vent adapter with the 7” diameter flex vent fireplace adapter included in the vent kit. Install the adapter collar with the screws removed from the standard fireplace collar. Refer to the fireplace manual for ad- ditional information on the vent collar removal and installa- tion.

4.Once the fireplace location has been determined, mark the ceiling where the flex vent will pass through. Cut an opening for installation of the firestop thimble assembly. The open- ing must measure a minimum of 9-1/2” x 9-1/2” square. See

Figure 32.

5.Next, determine the location for the cutout in the roof open- ing. This opening must be large enough to provide a mini- mum 1” air space clearance from the vertical vent pipe to any combustible framing.

6.Install the Firestop/Thimble assembly to the framed opening in the ceiling using common nails or screws.

Note: The thimble assembly is adjustable up or down as needed within the firestop. It is also designed with a pivoting firestop for use with 0 - 3/12 pitch cathedral ceilings.

7.To begin vent system assembly, first layout all the vent com- ponents on the floor in the order in which they will be as- sembled.

8.Stretch the 4” diameter inner flex flue and 7” diameter outer flex vent to the maximum length of 6 feet.

9.Install the spring spacers provided around the 4” diameter flex flue at 1 foot intervals, then slide the flue pipe with spac- ers into the 7” diameter outer flex vent pipe. Make sure the springs are spaced evenly starting at 12 inches from the fire- place collar. See Figure 33.
