Optima 70 - 2
20
1.
Place the Optima 70 in the framing. Locate the centerline of the termination and mark the
wall. Cut an 11” x 10” (279mm x 254mm) hole in the wall. NOTE: a 2” (50mm) x 1-
1/2” (13mm) around the 7” (178mm) liner is required. See Fig. 1 for termination framing.
2.
Locate the Horizontal termination head and the 4” (101mm) flexible exhaust pipe, and
“DRY” slip the exhaust pipe over the 4” (101mm) exhaust port on the termination head.
Un-slip the “DRY” connection and apply high temperature sealant to the 4” (101mm) flexi-
ble exhaust port and reattach to the 4” (101mm) exhaust connection on the termination
head and fasten with three screws on the pre-drilled locations. Repeat this same process
with the 7” (178mm) flexible liner.
3.
Locate the wall sleeve and cut to the thickness of the wall and slip it through the wall.
4.
Locate the Firestop and secure in place with 4 screws.
5.
Pull/Straighten the inner 4” (101mm) exhaust pipe to its maximum capacity and “wrap” the
spring spacers at every change of direction. And every 3ft (914mm) if longer lengths of
flexible liner is used. Next pull the 7” (178mm) intake liner over the 4” (101mm) exhaust
liner. NOTE: take care when “pulling/stretching out the liners, inspect for “breaks” in the
liners or in the termination head. Any “breaks in the venting system will cause poor flame
and improper combustion.
6.
Slip the assembled liner and termination head through the wall sleeve and make sure the
termination cap faces up and fasten the termination head to the wall with 4 screws pro-
vided with the kit. NOTE: If installing the termination head to vinyl or wood siding a Vinyl
Siding Deflector (VSD-1) is required. The VSD-1 must be set on top of the horizontal ter-
mination cap (fin side out) and then the two screws holding the termination cap are used
to secure the termination head and VSD-1.
7.
Apply high temperature sealant over the fireplace’s inner exhaust collar and slip the
4” (101mm) inner flexible exhaust liner down over it and attach the connection with three
screws.
8.
Repeat with the 7” (178mm) liner.
9.
Apply a bead of all weather silicone (not provided) around the termination head & house
to prevent water from entering in.
INSTALLATION PROCEDURES ARCHGARD DIRECT VENT (FLEX) SYSTEM
VENTING - HORIZONTALLY USING FLEXIBLE DIRECT VENT SYSTEMS
NOTES:
•
If installing a Vinyl Siding Deflector (VSD-1)
attach the VSD-1 to the front top of the
horizontal termination head “fin side out” to
ensure the termination head is not re-
cessed into the siding.
•
Horizontal sections of pipe MUST be sup-
ported every 3’ (914mm).
•
Spacers shall be installed at every change
of direction and every 3’ (914mm) if using
additional flexible pipe.
IMPORTANT: Do not locate termination head where excessive snow or ice build up may occur.
Check termination head area after every snow fall, and clear if necessary to prevent blockage.
If using snow blowers, make sure snow is not directed at the termination head.
NOTE:
Be sure to include 1/4”
(6mm) rise per foot of
horizontal length.
