45-DVFS28N-2 7

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 heater. 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” (3 mm) 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 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” w.c. (1.1 kPa) and a maximum of 8”

w.c. (2 kPa). The orifice is a #38 DMS (2.64 mm) drill size.

ELEVATION INPUT RATING 0-4500 ft (0-1372 M) 28,000 BTU/hr (8.2 kW) 4500 ft (1372 M) and above 28,000 BTU/hr (8.2 kW) less 4% per 1000 ft. (305 M) Please contact your local utility company or 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 #52 DMS (1.60 mm) drill size.

ELEVATION INPUT RATING 0-4500 ft. (0-1372 M) 28,000 BTU/hr (8.8 kW) 4500 ft. (1372 M) and above. 28,000 BTU/hr (8.8 kW) less 4% per 1000 ft. (305 M) Please contact your local utility company or 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.

LOCATING GAS HEATER

This appliance must be installed in a location that is free of plumbing, electrical wiring and heating or air conditioning ducts. Select a location that is accessible for venting.

See ALLOWABLE TERMINATION LOCATIONS listed in this manual.

NOTE: See venting chart for maximum and minimum vertical/horizontal venting configurations.

VENT TERMINATION LOCATIONS

1. See ALLOWABLE TERMINATION LOCATIONS and establish a suitable vent termination location.

2. In heavy snowfall areas make sure the vent termination is located where it can not be blocked by snow and from snowfall or snow removal equipment.

3. Locate the vent termination away from plants, bushes or any other object near the vent termination

that will interfere or obstruct the air flow around it.

4. DO NOT recess vent termination into walls, sidings or planters.

5. Vent terminations located below 7ft (2.13 M) from grade level or anywhere that it can be a burn

hazard to the public, such as patios and balconies, must be protected with an approved termination cage. If using Archgard Venting System order (Part # 999-DV-SC).

VENTING CONNECTION

For best and safe venting performance, here are some general venting rules:

 Use only Archgard or Simpson Dura-Vent direct vent systems and components.

 Maintain a minimum of 1” (25 mm) clearance to combustibles from the outside surfaces of

vertical vents and minimum of 1” (25 mm) sides and bottom, and 2” (50 mm) from top surfaces of horizontal vents.

 Observe local code restrictions, if any, regarding the installation of this type of gas appliance.

 Observe the venting charts given in this manual

 Use vent spacers between the inside 4” (101 mm) and outside 7” (178 mm) vents at 3 ft (915

mm) intervals (Archgard Direct Vent System ONLY).

 Never slope horizontal vents downwards, towards the vent termination.

 Maintain a minimum ¼” rise (6mm) for every linear foot (305 mm) of horizontal vent.

 Terminate (Horizontally) the vent only with an approved vent termination supplied by Archgard

Part # 999-DV-HTC or Simpson Dura-Vent Termination Cap.

 Terminate (Vertically) the vent only with Simpson Dura-Vent Vertical Termination Cap.

 Support horizontal vents every 3 ft (915 mm) to prevent sagging.

Please, strictly follow the venting instructions for optimum performance from

the appliance, and to avoid sooting and/or service calls.

VENTING ABOVE ROOF OF THE HOUSE USING A VERTICAL TERMINATION

Use Simpson Dura-Vent listed direct vent system caps for all vertical vent termination

applications (through the roof).

Please strictly follow the venting instructions for optimum performance from the appliance and to avoid sooting and/or service calls.

45-DVFS28N-2 14

VENTING - VERTICAL TERMINATION USING SIMPSON DURA-VENT PIPE

The Optima 45 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 Adaptor and connect the adaptor to the top of flue outlet on the Optima 45 gas fireplace.

1. Maintain 1” (25 mm) clearance (air space) to combustibles when passing through ceilings walls, roof, enclosures, attic rafter, or other nearby combustible surfaces. Do not pack air spaces with insulation. Check page 13 (Venting Chart) for the maximum vertical rise of the venting system.

2. Set the gas appliance in its desired location. Drop a plum 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 previously 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” (254 mm) 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), if using Simpson Dura-Vent from the appliance up through the roof. Ensure that all Simpson Dura-Vent and/or flexible is 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” (25 mm). 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.

NOTE: Apply high temperature sealant to inner and outer pipe on every Simpson Dura-Vent twist-lock joint. See Fig. 3

VENTING - VERTICAL TERMINATION USING SIMPSON DURA-VENT PIPE

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 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.

 Any storage spaces or closets which the vent

must pass through must be enclosed.
