VERTICAL THRU THE ROOF APPLICATIONS
c)A minimum of an 8 ft. vertical rise.
d)Two sets of 45 degree elbow offsets within these vertical installations. From 0 to a maximum of 8 ft. of vent pipe can be used between elbows. (Fig. 25)
e)7DVCS must be used to support offsets. (Fig. 26) This application will require that you first determine the roof pitch and use the appropriate starter kit. (See Venting Components List)
TO INSTALL VERTICAL VENTING
1. | Locate your fireplace. |
2. | Plumb to centre of the (4") flue collar from ceiling |
| above and mark position. |
3. | Cut opening equal to |
4. | Proceed to plumb for additional openings through the |
| roof. In all cases, the opening must provide a minimum |
| of 1 inch clearance to the vent pipe, i.e., the hole must |
| be at least |
5. | Place fireplace into position. |
6. | Place firestop(s) #7DVFS or Attic Insulation Shield |

7. | Install roof support (Fig. 27) and roof flashing making |
| sure upper flange of flashing is below the shingles. Fig. 30. |
8. | Install appropriate pipe sections until above the flash- |
| ing. (See Fig. 30). |
9. | Install storm collar and seal around the pipe. |
10. Add additional vent lengths for proper height. Fig. 28. | |
