HORIZONTAL INSTALLATION, cont.

Step 3.

With the adapter and pipe attached to the stove, slide the stove into its correct location, maintaining minimum clearance to combustibles. Mark the wall for a 10” x 10” (254mm x 254mm) square hole. The center of the square hole should line up with the centerline of the horizontal pipe, as shown in Fig. 6. Cut and frame the hole in the exterior wall where the vent will be terminated. If the wall being penetrated is constructed of noncombustible material, i.e. masonry block or concrete, a 7” (178mm) diameter hole is acceptable.

Also, if you have installed the Hearth Legs, they will reduce the centerline clearance by 3" (75mm).

NOTE:

(1)Installation requires a minimum of 1’ (305mm) horizontal run of vent with a 1⁄4” (6mm) rise run towards the termination. Each 1’ (305mm) of horizontal venting must include a 1/4” rise. Never allow the vent to run downward. This could cause high temperatures and may present the possibility of a fire.

(2)The location of the horizontal vent termination on an exterior wall must meet all local and national building codes, and must not be easily blocked or obstructed, see page 26.

(3)For installations requiring a vertical rise on the exterior of the building, Aladdin Snorkle Kit #844-8920, 14” (356mm) and 36” (914mm) tall snorkel terminations are available. Follow the same installation procedures as used for standard horizontal terminations. If the snorkel termination must be installed below grade (i.e. basement application), proper drainage must be provided to prevent water from entering the snorkel termination. Do not backfill around snorkel termination.
