DIRECT VENT SPECIFICS - MODEL GDS50

VENTING LENGTHS &

AIR TERMINAL LOCATIONS

Use only Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp or American Metal Amerivent venting components.

Minimum and maximum vent lengths, for both horizontal and vertical installations, and air terminal locations for ei- ther system are set out in this manual and must be ad- hered to. For Simpson Dura-Vent, Selkirk Direct Temp and American Metal Amerivent, follow the installation procedure provided with the venting components.

For vent systems that provide seals on the inner exhaust flue, only the outer air intake joints must be sealed using a red high temperature silicone (RTV). This same sealant maybe used on both the inner exhaust and outer intake vent pipe joints of all other approved vent systems except for the exhaust vent pipe connection to the fireplace flue collar which must be sealed using the black high tempera- ture sealant Mill Pac. High temperature sealant must be ordered separately.

Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp and American Metal Amerivent venting systems must not be combined.

A starter adaptor must be used and may be purchased from the corresponding supplier:

Dura-Vent	GDS924N
Amerivent	4DSCB-N1
Direct Temp	4DT-AAN

When using Napoleon venting components, use only the following vent kits: WALL TERMINAL KIT GD175 (7-1/2' of venting included), or 1/12 TO 7/12 PITCH ROOF TERMINAL KIT GD110, 8/12 TO 12/12 ROOF TERMINAL KIT GD111, FLAT ROOF TERMINAL KIT GD112 or STOVE PERISCOPE KIT GD180 (for wall penetration below grade) in conjunc- tion with the appropriate venting components.

These vent kits allow for either hori-

zontal or vertical venting of the stove. FIGURES 4, 5, & 6. The maxi-

mum number of 4" flexible connec- tions is two horizontally or three vertically (excluding the stove and

the air terminal connections).

When terminating vertically, the minimum vertical rise is 34 inches above the stove and the maximum vertical rise is 40 feet. FIGURE 3.

Deviation from the minimum ver- tical vent length can create diffi- culty in burner start-up and/or carboning.

Use an adjustable pipe as the final length of rigid piping to the stove for ease of installation.

We recommend that exhaust vents that pass through unheated spaces be wrapped in a protective sleeve to minimize condensation and reverse flow symptoms. See Trouble Shooting for details.

For optimum flame appear- ance and stove perfor- mance, keep the vent length and number of el- bows to a minimum. On extreme vent configura- tions, allow several min- utes (5-15) for the flame to stabilize after lighting. The air terminal must remain unobstructed at all times. Examine the air terminal at least once a year to verify that it is unobstructed and undamaged. FIGURE 4

The maximum horizontal run is 34 inches with a 90o elbow located 29" above the stove. FIGURE 4.

The maximum horizontal run with a 57 inch vertical rise immediately above the stove is 20 feet FIGURE 5.

IF VERTICAL RISES GREATER THAN 57 INCHES ARE NECESSARY, THE INCREASED RISE MUST BE DEDUCTED FROM THE HORIZONTAL RUN.

A terminal shall not terminate directly above a side- walk or paved driveway which is located betweeen two single family dwellings and serves both dwell- ings. Local codes or regulations may require dif- ferent clearances.

Do not allow the inside liner to bunch up on hori- zontal or vertical runs and elbows. Keep it pulled tight. a 1-1/4" air gap all around between the inner liner and outer stove pipe is required for safe op- eration. Use a firestop when penetrating interior walls, floor or ceiling.

All horizontal runs must have a minimum ¼ inch rise per foot.
