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 ⅛” (3mm) NPT plugged tapping accessible for connection to a test gauge. When
connecting the supply line to the gas valve, the installer should brace the gas valve to ensure
that it 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
½ 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 ½ 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.

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.

2. Set the gas appliance in its desired location. Drop a plumb bob down from the ceiling to the
position of the appliance flue exit, and mark the location where the vent will penetrate the
ceiling. Drill a small hole at this point. Next, drop a plumb bob from the roof to the hole previ-
ously drilled in the ceiling, and mark the spot where the vent will penetrate the roof.
NOTE: you may wish to relocate the appliance to avoid cutting load-bearing members.
3. A Firestop spacer must be installed in the floor or ceiling of every level. To install the Firestop
spacer in a flat ceiling cut a 10” (254mm) square hole. Frame the hole as shown Fig. 1 and
install the firestop.
4. Assemble the desired lengths of pipe and elbows as outlined in the Venting Chart, necessary
to reach from the Appliance adaptor (999-DV-SDA). Ensure that all Simpson Dura-Vent and/
or flexible gas liners are connected and sealed accordingly.
5. Cut a hole in the roof centered on the small drill hole placed in the roof as outlined in Step 2.
6. The hole should be of sufficient size to meet the minimum requirements for each combusti-
bles of 1” (25mm). Slip the flashing under the shingles (shingles should overlap half of the
flashing) as per Fig.2.
7. Continue to assemble pipe lengths and/or flexible gas venting.
8. Ensure vent is vertical and secure the base of the flashing to the roof with roofing nails;
slide storm collar over the section and seal with a mastic.
9. Install the vertical termination cap by twist-locking it.

VENTING - VERTICAL TERMINATION USING SIMPSON DURA-VENT PIPE ONLY
The 72-DVT30N-2 can be vented vertically using Simpson Dura-Vent Direct Vent System. To
vent using Simpson Dura-Vent exclusively, you must use the Archgard 999-DV-SDA Adapter
and connect the adapter to the top of flue outlet on the Optima 72 gas fireplace.

NOTE:
• Galvanized pipe is desirable above the roofline
due to its higher corrosion resistance. Continue
to add pipe sections throughout the flashing
until the height of the vent cap meets the mini-
mum 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, increas-
ing the height may solve a drafting problem.
REMEMBER to check that you are within the
maximum vertical height restrictions, and are
placing the appropriate vent restrictors as out-
lined in the venting chart within this manual.
• Any storage spaces or closets which the vent
must pass through must be enclosed.

The 72-DVT30N-2 can be used with Flexmaster Model GA 4” & 7” (101mm & 178mm) vent
liners, and terminate through the roof using Simpson Dura-Vent by using an 999-DV-SDA
(Adapter, Flex to Simpson Dura-Vent).
• Refer to the venting chart before considering vertical termination.
• Check the Allowable Termination Locations chart within this manual.
CONNECTING THE 999-DV-SDA ADAPTER TO FLEX & SIMPSON DURA-VENT
Clearance to combustible material and fire-stops
must be installed as required by local codes; in the
absence of local codes, in accordance with the local
enforcing authority.
VENTING - VERTICAL TERMINATION USING FLEX GAS LINER
FLEXIBLE PIPE CONNECTIONS
1. The intake pipe must be
securely fastened to the
appliance and to the terminal
and all joints must 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 temperature non-silicone
sealant approximately
¼” (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
should be installed at every
change of direction and every
3 ft. (914mm).
4. See Fig. 1 & 2 to determine
where to place the 999-DV-
SDA adapter, and connect the
999–DV-SDA adaptor as
shown in Fig. 3.
5. Follow all vertical venting di-
rections as outlined in the Ver-
tical termination sections.
Connecting the SDA-U Adaptor
Slide the 4” (101mm) flex pipe over the 4” (101mm) section of
the 999-DV-SDA adapter, and secure with a bead of mil-pac or
other non-silicone sealant (DO NOT use silicone) and 3
screws. Repeat the process for the 7” (178mm) liner. Follow
with Simpson Dura-Vent Pipe and guidelines for installation as
outlined within this manual
