Before connecting the appliance to the gas supply line, double check that the appliance you
have purchased is designed for the gas type you are using. The gas type markings are located
on the certification label and also on the appliance’s gas valve.
Adequate clearance for proper installation and checking of the gas connections must be
provided. All gas connections must be checked for gas leaks.
GAS CONNECTIONS
Have your gas supplier or a qualified gas fitter run a gas supply line into the fireplace.
The line must be properly sized and fitted according to the installation codes. Immediately
upstream of the supply connection, the fitter shall provide an accessible manual shut-off valve
and a 1/8” (3mm) NPT plugged tapping accessible for connection to a test gauge. When
connecting the supply line to the gas valve, the installer shall brace the gas valve to ensure that
gas valve is not moved from its bracket. If the valve is not braced when the supply line is
connected, the valve may be moved and cause a “break” in the main burner supply line. Such
damage is not covered by the manufacturer’s warranty.
CAUTION: The appliance and its individual shutoff valve must be disconnected from the gas
supply piping system during any pressure testing of that system at test-pressures in excess of
1/2 psig (3.5 kPa). The appliance must be isolated from the gas supply piping system by
closing its individual manual shutoff valve during any pressure-testing of the gas supply piping
system at test pressures equal to or less than 1/2 psig (3.5 kPa). Failure to do so will damage
the appliance’s gas valve. Such damage is not covered by the manufacturer’s warranty.
Natural Gas Pressure Settings:
The inlet supply or line pressure must be a minimum of 4.5” W.C. (1.1 kPa) and a maximum of
14 W.C. (3.5 kPa). The orifice is a #37 DMS (2.64 mm) drill size.

4500 ft (1372 M) and above. 30,000 BTU/hr (8.8 kW) less 4% per 1000 ft. (305 M)
Please contact your local distributor for the appropriate orifice size you require.
Propane Pressure Settings:
The inlet supply or line pressure must be a minimum of 11” W.C. (2.8 kPa) and a maximum of
14” W.C. (3.5 kPa). The orifice is a #51 DMS (1.70 mm) drill size.

4500 ft. (1372 M) and above. 30,000 BTU/hr (8.8 kW) less 4% per 1000 ft. (305 M)
Please contact your local distributor for the appropriate orifice size you require
NOTE: THE INPUT RATING SHOULD ALWAYS BE CHECKED WHEN FIRST RUNNING
THIS APPLIANCE. To do this, reduce the background flow rate, time the meter, light the
fireplace and take another reading after 15 minutes of operation. Check with your gas supplier
for the gas BTU content at your elevation. Input is the rate of flow multiplied by the heating
value of the gas (cubic feet/hour x BTU per cubic feet). Adjust the manifold pressure so that
the unit does not operate above the rated input.

NOTE:
• Galvanized pipe is desirable above the roof-
line due to its higher corrosion resistance.
Continue to add pipe sections throughout the
flashing until the height of the vent cap meets
the minimum height requirements specified in
Fig. 5. or local codes.
• For steep roof pitches, the vertical height
must be increased. A poor draft, or down
drafting can result in high wind conditions,
trees or neighbor's roof lines. In these cases
increasing the height may solve a drafting
problem. REMEMBER to check that you are
within the maximum vertical height restric-
tions, and are placing the appropriate vent
restrictors as outlined in the venting chart
within this manual.
• Any storage spaces or closets which the vent
must pass through must be enclosed.

FLEXIBLE PIPE CONNECTIONS
1. The intake pipe shall be
securely fastened to the
appliance and to the terminal
and all joints shall be secured
using a minimum of 3 screws
evenly spaced around the pipe.
2. Approximately 1” (25mm)from
the end of the 4” (101mm) pipe
outlet at the appliance and at
the 4” (101mm) terminal inlet
apply a bead of high tempera-
ture silicone approximately
1/4” (6mm) wide. Slide the
4” (101mm) pipe onto the
appliance and secure with 3
screws evenly spaced to the
outlet. Repeat the procedure at
the terminal inlet.
3. Install a vent spacer between
the outer and the inner liner to
maintain clearances. Spacers
shall be installed at every
change of direction and every
3” (76mm).
4. See Fig. 1 & 2 to determine
where to place the SDA-1
adaptor, and connect the SDA-
1 adaptor as shown in Fig. 3.
5. Follow all vertical venting direc-
tions as outlined in the Vertical
termination sections.
Connecting the SDA-1 Adaptor
Slide the 4” (101mm) flex pipe over the 4” (101mm) section of
the SDA-1 Adaptor, and secure with a bead of high tempera-
ture silicone and three screws. Repeat the process for the
7” (178mm) liner. Follow with Simpson Dura-Vent Pipe and

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.
