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 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.

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 (2.65 mm) drill size.

ELEVATION INPUT RATING 0-4500 ft (0-1372 M) 30,000 BTU/hr (8.8 kW) 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 #52 DMS (1.62 mm) drill size.

ELEVATION INPUT RATING 0-4500 ft. (0-1372 M) 30,000 BTU/hr (8.8 kW) 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.

LOCATING GAS FIREPLACE

This appliance must be installed in any 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. The fireplace may be

installed in any location that maintains proper clearances to combustibles, air conditioning ducts, electrical wiring and plumbing. Select a location that is accessible for venting See section Allowable Termination Locations listed in this manual. When the appliance is installed directly on carpeting, vinyl tile or other combustible materials, other than wood flooring, the appliance must be installed on metal or wood panel extending the full width and depth of the appliance.

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

VENT TERMINATION LOCATIONS

ALLOWABLE TERMINATION LOCATIONS and establish a suitable vent termination location.

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

2. Locate the vent termination away from plants, bushes or any other object near the vent termination that will interfere with or obstruct the airflow around it.

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

4. 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 # C-1.

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” (25mm) clearance to combustibles from the outside

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

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” (101mm) and outside 7” (178mm) vents at 3 ft

(915mm) 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 (305mm) of horizontal vent.

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

Archgard Industries (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 (915mm) to prevent sagging.

Please strictly follow the venting instructions for optimum performance from the

appliance and to avoid sooting and/or service calls.

RESTRICTOR PLACEMENT FOR ROOFTOP VENTED APPLICATIONS ONLY

WARNING: These restrictors are only to be installed in the vent system if the vent exceeds 10’ in

vertical height. Restrictor Number 1 below is required if the vent system is between 10’-18’ and Restrictor Number 2 below is required if the vent system exceeds 18’. Installing them under any

other circumstances may cause hazardous venting conditions and may result in personal injury, property damage or death.

NOT FOR USE IN SIDEWALL VENTED APPLICATIONS

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.

72-DVT30N

VENTING - VERTICAL TERMINATION USING SIMPSON DURA-VENT PIPE ONLY

The Optima 72 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.

1. Maintain 1” (25mm) 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 15 (Venting Chart) for the maximum vertical rise of the venting system.

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 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” (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.
