Waterford Appliances T25-LP, T25-NG Vent Restrictor, DURA-VENT Horizontal Installations

INSTALLATION

VENT RESTRICTOR

The above Offset to Vertical Installation re- quires more restriction, the Vent Restrictor must be set to 5/8" (16mm).

The Vent Restrictor on the stove comes preset with a 7/8" (22mm) opening. The Vent Restrictor is located inside the firebox over the flue outlet.

To adjust the restrictor simply use a large phillips screwdriver to loosen the 2 retaining screws and slide the restrictor up to a 5/8" gap. Tighten the screws to secure it in position.

DURA-VENT

HORIZONTAL

INSTALLATIONS

1)Set the unit in its desired location. Check to determine if wall studs or roof rafters are in the way when the venting system is attached. If this is the case, you may want to adjust the location of the unit.

2)Direct Vent pipe and fittings are designed with special twist-lock connections to con- nect the venting system to the appliance flue outlet. A twist-lock appliance adapter is installed on the unit at the factory. Assem- ble the desired combination

of pipe and elbows to the appliance adapter with pipe seams oriented towards the wall or ceiling, as much out of view as possible.

The final positioning of the pipe and 90o elbow assembly is determined by the mounting orienta- tion of the adapter on the stove and twist- l o c k e d

for a sol- id con - nection.

Note:

a)Twist-lock procedure: Four indenta- tions, located on the female ends of pipes and fittings, are designed to slide straight onto the male ends of adjacent pipes and fittings, by ori- enting the four pipe indentations so they match and slide in to the four entry slots on the male ends (dia- gram 1). Push the pipe sections com- pletely together, then twist-lock one section clockwise approximately one-quarter turn, until the two sec- tions are fully locked. The female locking lugs will not be visible from the outside on the Black Pipe or fittings. They may be located by examining the inside of the female ends. Apply sealant "Mill-Pac" to in- ner pipe and high temp silicone seal- ant to outer pipe on every twist-lock joint.

Hint: Apply silicone to f e m a l e end.

b)Horizontal runs of vent must be sup- ported every three feet. Wall straps are available for this purpose.

3)With the pipe attached to the stove, slide the stove into its correct location, and mark the wall for a 10" x 10" (inside dimensions) square hole. The center of the square hole should line up with the centerline of the horizontal pipe. Cut and frame the 10 inch square hole in the exterior wall where the vent will be terminated. If the wall being penetrated is constructed of non-combus- tible material, i.e. masonry block or con- crete, a 7" diameter hole is acceptable.

Note:

a)The horizontal run of vent should have a 1/4 inch rise for every 1 foot of run towards the termination. Nev- er allow the vent to run downward. This could cause high temperatures and may present the possibility of a fire.

b)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 External Vent Ter- minal Locations, see diagram on page 10.

4)If installing the vent termination to a wall with vinyl siding, the Vinyl Siding Standoff must be used. Attach the Vinyl Siding

Standoff to the Horizontal Vent Termination, but first run a bead of non-hardening mastic around its outside edges, so as to make a seal between vent cap and the standoff. Install the Vinyl Siding Standoff (Part # 950) between the vent cap and the exterior wall and attach with the four wood screws provided. Seal around the Vinyl Siding Stand- off on all four sides. Diagram 2. Thearrow on the vent cap should be pointing up. Insure that the 1-1/4" clearances to com- bustible materials are maintained. See dia- gram 2.

Diagram 2

Note: If installing termination on a siding covered wall, a vinyl siding stand- off or furring strips must be used to ensure that the termination is not recessed into the siding. The f o u r w o o d s c r e w s p r o v i d e d should be replaced with appropri- ate fasteners for stucco, brick, concrete, or other types of sid- ings.

5)Before connecting the horizontal run of vent pipe to the vent termination, slide the black decorative wall thimble cover over the vent pipe, then slide the Wall Thimble (Part # 942) over the vent pipe.

6)Slide the appliance and vent assembly to- wards the wall carefully inserting the vent pipe into the vent cap assembly. It is impor- tant that the vent pipe extends into the vent cap a sufficient distance so as to result in a minimum pipe overlap of 1-1/4 inches.
