Horizontal Vent Installation
IMPORTANT NOTES:
1. All Ravelle™ 30 gas fireplaces that are horizontally terminated
may only use 6-5/8” x 4” direct-vent pipe by Security Chimneys™
or Dura-Vent
®
.
2. When this pipe passes through a wall, a wall thimble - Security
Chimneys part number SV4RSM or Dura-Vent part number 942 is
required. The hole in the wall for the wall thimble should be 9-1/4”
wide by 10-1/4” high.
3. Horizontal runs of vent must be supported every three feet. Wall
straps - Security Chimneys part number SV4BM or Dura-Vent part
number 988 are available for this purpose.
4. If the vent passes through a ceiling or floor, a firestop - Security
Chimneys part number SV4BF or Dura-Vent part number 1263 - is
required.
5. Also note that venting terminals shall not be recessed into a wall
or siding. If installing the termination cap on a wall covered with
siding, a vinyl siding standoff - Security Chimneys part number
SV4VS or Dura-Vent part number 1250 - or furring strips must be
used to ensure that the termination cap is not recessed into the
siding.
6. The horizontal run of vent must have a 1/4” (6 mm) rise for every
one foot of run towards the termination.
7 If the wall being penetrated is constructed of non-combustible
material, such as masonry block or concrete, a 7-1/2” (191 mm)
diameter hole is acceptable and a wall thimble is not required.
8. The location of the horizontal vent termination on an exterior wall
must meet all local and national building codes and must not be
blocked or obstructed. For allowable external vent terminations
locations, see the diagram on Page 23.
9. Allowable clearances from the vent pipe to combustible materials
must be maintained. See Page 10 for these clearances.
10. Do not locate the termination cap where it may be blocked by
shrubbery or snow.
