WARNING: Failure to position the parts in accordance with these diagrams or failure to use only parts
specifically approved with this appliance may result in property damage or personal injury.
The installer must mechanically attach the marking supplied with the gas fireplace insert to the inside of
the firebox of the fireplace into which the gas fireplace insert is installed. Cutting of any sheet-metal
parts of the fireplace, in which the gas fireplace insert is to be installed, is prohibited. If the factory-built
fireplace has no gas access hole(s) provided, an access hole of 1½” (37.5 mm) or less may be drilled
through the lower sides or bottom of the firebox in a proper workmanship like manner. This access hole
must be plugged with non-combustible insulation after the gas supply line has been installed. The
fireplace flue damper can be fully blocked open or removed for installation of the gas fireplace insert.
The fireplace and fireplace chimney must be clean and in good working order and constructed of noncombustible materials. The chimney cleanouts must fit properly. Refractory, glass doors, screen rails,
screen mesh and log grates can be removed from the fireplace before installing the gas fireplace insert.
Smoke shelves, and baffles may be removed if attached by mechanical fasteners. Trim panels must
not seal ventilation openings in the fireplace.

GAS CONNECTIONS
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.
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 must provide an accessible manual shut-off valve and a ⅛ (3
mm) NPT plugged tapping accessible for connection to a test gauge. When connecting the
supply line to the gas valve, the installer must 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
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.
Natural Gas Pressure Settings:
The inlet supply or line pressure must be a minimum of 4.5” wc (1.1 kPa) and a maximum of 8”
wc (2 kPa). The orifice has a #31 DMS (305 mm dia.) drill size.
ELEVATION INPUT RATING
0-4500 ft. (0-1372 M) 40,000 BTU/hr (11.7 kW)
4500 ft. (1372 M) and above 40,000 BTU/hr (11.7 kW) less 4% per 1000 ft. (300 M)
Please contact your local distributor for the appropriate orifice size.
Propane Pressure Settings:
The inlet supply or line pressure must be a minimum of 11” wc (2.8 kPa) and a maximum of 14”
wc (3.5 kPa). The orifice has a #49 DMS (1.85 mm dia.) drill size.
ELEVATION INPUT RATING
0-4500 ft. (0-1372 M) 40,000 BTU/hr (11.7 kW)
4500 ft. (1372 M) and above 40,000 BTU/hr (11.7 kW) less 4% per 1000 ft. (300 M)
Please contact your local distributor for the appropriate orifice size.
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.

LEVELING THE OPTIMA 40-SB DIRECT VENT INSERT
Before placing the appliance into the fireplace, check the hearth of the fireplace to see if it is
level with the front of the fireplace. If it is not, measure the depth of the hearth. Loosen the
three screws of the leveling “L” bracket at the back of the appliance. Lower it to the
measurement obtained and tighten the screws
ELECTRICAL CONNECTIONS
The Optima 40-SB comes complete with a temperature activated fan and rheostat installed
and wired to a three-prong (grounding) plug for your protection against shock hazard and
should be plugged in directly into a properly grounded three-prong receptacle. Do not cut or
remove the grounding prong from this plug.
NOTE: This appliance, when installed, must be electrically grounded in accordance with local
codes or, in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70, or
the Canadian Electrical code, CSA C22.1.
Optima 40 - SB 11
VENTING INSTRUCTIONS
WARNING: Operation of this heater when not connected to a properly installed and maintained venting system can result in carbon monoxide (CO) poisoning and possible death.
The appliance must not be connected to a chimney flue serving a separate solid fuel
burning appliance.
Caution: Only two 3” (76 mm) “FLEX-MASTER” Model GA gas flex vent liners (or approved equivalent)
and a vent terminal is approved for use with this appliance.
Approved vent terminals are:
Archgard terminal. Part # 999-INS-TK.
Simpson Dura-Vent terminal. Part # 980, 923GK (adaptor with flashing) or 991 (high wind cap)
NO OTHER VENTING SYSTEM OR COMPONENTS MAY BE USED. If you are using DuraVent vertical
termination cap, follow the instructions provided with the DuraVent cap.
This appliance is designed to attach to two 3” (76 mm) co-linear aluminum flex gas liners running the full
length of the chimney. The flue length must be a minimum of 8’ (2.44 M) and a maximum of 35’ (10.6 M)
The minimum flue size is 4” x 7” (100 mm X 178 mm). Masonry chimneys may take various contours
which the flexible liner will accommodate, however, keep the flexible liner as straight as possible, avoiding
unnecessary bending but at all times keep a minimum of 3” (76 mm) inside bend radius.
The Air Intake Flex Liner must be connected to the inlet air collars of the termination cap and the appliance. The Exhaust Flex Liner must be connected to the exhaust collars of the termination cap and the
appliance. (DO NOT MIX UP THESE CONNECTIONS).
The Air intake and Exhaust connections are marked on the gas appliance. See Fig. 1.
CAUTION: To ensure that the venting path is not accidentally obstructed, or punctured the
damper of the host fireplace must be permanently disabled. By either complete removal of the
damper or welding it in it’s “open” position. Temporarily disabling the damper with braces,
wedges, brackets, ext,. Is not allowed.

VENTING INSTRUCTIONS 999-INS-TK
Instructions for use with Archgard vertical termination cap. Part # 999-INS-TK. Install the termination cap being sure to provided sufficient space (around and on top) so as to not to impede the
flow of air both into and out-of the cap. This cap is only to be used for non combustible installations. Do not recess into the top of the chimney.
1. Mark each end of one liner with “Air Intake”.
2. Mark each end of the second liner with “Exhaust”.
3. Pull the liner through the chimney.
4. Install the flashing. Do Not bend or cut the flashing in any way.
5. Seal and attach the liner marked “Air Intake” to the vent terminal pipe marked “Air Intake” with the collar
clamp provided.
6. Seal and attach the liner marked “Exhaust” to the vent terminal pipe marked “Exhaust” with the collar clamp
provided.
7. Seal and attach the end of the flex marked “Air Intake” to the collar marked “Air Intake” on the appliance with
the collar clamp provided with the unit.
8. Caulk all joints as usual.
NOTE: The vertical termination cap must be sealed to the liner with suitable high temperature sealant and with the
hose clamps fasteners provided. The liners must form a complete connection from the appliance flue collars to the
vertical termination cap.
