Vermont Casting IRFSDV24, IRFSDV34 installation instructions Below Grade Installations

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).

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.
