Below Grade Installations (Snorkel) - Irving IRFSDV24 Installation Instructions And Homeowner's Manual

STEP 5
Measure the horizontal length requirement including a
2" (50 mm) overlap, i.e. from the elbow to the outside
wall face plus 2" (or the distance required if installing a
second 90 elbow (Fig. 21).
Always install horizontal venting on a
level plane.
STEP 6
Note: If using the charcoal wall plate, Part #52202-CG,
and collar, Part #52203-CG, put them in place before
putting the pipe sections through the wall.
Use appropriate length of pipe sections - telescopic or
fixed - and install. The sections which go through the
wall are packaged with the starter kit, and can be cut to
suit if necessary (Fig. 22).
Sealing vent pipe and firestop gaps with
high temperature sealant will restrict
cold air being drawn in around fireplace.

STEP 7
Apply high temperature sealant to 4" (100 mm) and 7"
(175 mm) collars or the termination one inch away from
crimped end. Guide the vent terminations 4" and 7"

 
collars into their respective vent pipes. Double check
that the vent pipes overlap the collars by 2" (50mm).
Secure the termination to the wall with screws provided
and caulk around the wall plate to weatherproof.
             


 
  
Support horizontal pipes every 3' (91 cm)
with metal pipe straps.
Check fireplace to make sure it is lev-
elled and properly positioned.
BELOW GRADE INSTALLATIONS
When it is not possible to meet the required vent
terminal clearances of 12 inches (305mm) above grade
level a snorkel vent kit is recommended. It allows
installation depth of down to 7 " (178mm) 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.
Ensure sidewall venting clearances are observed.
