VENTING - HORIZONTALLY USING SIMPSON DURA-VENT DIRECT VENT SYSTEMS

The Optima 45-3 can be vented horizontally using Simpson Dura-Vent Direct Vent System. To vent using Simpson Dura-Vent exclusively, you must use the Archgard SDA-U Adaptor and connect the SDA-U adaptor to the top of the Optima 45-3 as shown in Fig. 1.

NOTE: Apply high temperature sealant to the SDA-U adaptor and the flue connection on the Optima 45-3. Seal all pipe joints and follow all venting instructions within this manual.

NOTE: Call your local Authorized Archgard Dealer to purchase Simpson Dura-Vent Direct Vent Kits and/or venting components.

Minimum components required for horizontal termination using Simpson Dura-Vent:

1	SDA-U (Appliance adaptor)	1	90 Deg. Elbow
1	Horizontal Termination Cap	1	Wall Thimble
1	Length of pipe for top of appliance	1 Length of pipe to suit wall thickness

Measure wall thickness from the back of the fireplace standoffs to inside mounting surface of the termination cap. If a Vinyl siding standoff is required, measure to the outside surface of the wall without siding and add 2” (50 mm).

NOTE: The Termination cap must NOT be recessed into siding. Measure wall thickness including finishing straps.
