Drolet GTX-I manual Horizontal wall vent termination, Apply sealant On four sides

3.3.4.4 Horizontal wall vent termination

The position of the horizontal vent termination must be positioned in such a way as to meet all local building codes. Attach the correct length of vertical section pipe and an elbow fitting to the stove. Mark the center line of the pipe facing the wall (allowing for a 1/4” rise per foot of horizontal, example 10 ft of horizontal would require a rise of 2.5”).

NOTE: ALLOWING THE VENT PIPE TO SLOPE DOWN TOWARDS THE VENT TERMINATION COULD CAUSE POOR COMBUSTION AND/OR HIGH TEMPERTURES THAT MAY PRESENT A FIRE HAZARD.

Mark a 10” x 10” square around the center mark (inside dimensions).Cut and frame the exterior wall to except the wall thimble. Install the wall thimble shield using wood screws. If the wall being penetrated is constructed of non-combustible material, a 7” hole for the vent pipe is acceptable.

On four sides

Caution: When installing the terminal on to vinyl siding, a vinyl siding kit or furring strips must be used to prevent the terminal from being recessed into the siding.

When the termination is to be attached to vinyl siding, apply a bead of non-hardening mastic around the outside edge to form a seal between the standoff and the terminal. Attach the terminal to the exterior wall using four wood screws through the holes in the corner of the vent terminal. Complete the terminal installation; apply a bead of mastic around the outer edge of the vinyl standoff. With the termination installed you can now connect the completed vent assembly by sliding the unit back towards the wall and carefully inserting the pipe into the terminal. Before the final connection is made slide on the decorative wall thimble. Secure the terminal by securing the termination straps to the pipe as close to the exterior wall as possible using sheet metal screws, ensure that the straps are hidden by the wall thimble cover. Apply decorative trim if required.

Before sliding the pipe into the termination, ensure that you have slid the decorative wall thimble cover and penetration heat shield over the pipe.

Slide the pipe into the vent, making sure that at least 11/4” overlap between the pipe and the terminal. Attach the pipe by attaching two sheet metal screws through the terminal straps and into the pipe. Bend back the straps towards the terminal making sure they are hidden by the decorative thimble. Finally attach the wall penetration heat shield and secure with wood screws
