Installation
Typical Application & Location
Installation must be in accordance with recognised standards in the country concerned, for North America, NEC / CEC regulations should be followed.
The AGS Timed Gas Control unit (TGC) is carefully designed for the commercial and hospitality sector to control the gas supply for a range of appliances such as fireplaces, fire pits and barbeques etc.
The controller incorporates a simple user interface to open/close gas lines and an automatic shutoff timeout feature is configurable via switches upon installation. The controller can also be integrated with remote devices with an open/close circuit isolating the gas supply in an emergency.
Located and installed in positions determined by those who have knowledge of the process plant system and equipment involved, and in consultation with both safety and electrical engineering personnel.
The controller should be installed in the correct orientation, as recommended by the manufacturer at a height to suit public access and status observation (if intended for public use) and is designed for indoor operation unless used in conjunction with a weatherproof cover (sold separately).
Mounting & Cabling
- If mounting direct to wall – ensure the wall surface is flat to prevent base distortion!
- Where suitable cable glands/conduits are used for wire entry, use 20mm (3/4 inch) max separated by at least 20mm!
- Fill any holes drilled to maintain integrity of the equipment!
- Any parts that form part of the connections/installation must have a minimum fire-retardant rating of UL 94V-2!
- Restrain the hazardous live wiring from accidental loosening to prevent wires from moving after installation and touching parts of opposite polarity or at low voltages!
- A switch or circuit breaker must be fitted, it must be accessible and marked as the disconnecting device!
- Isolate the equipment from all hazardous live power sources before opening the cover!
- When metal conduit is used provision shall be provided by the installer for bonding in accordance with the NFPA70.
-
Carefully remove the front cover from the unit by using an M3 socket wrench.
-
Using the rear base – mark mounting holes to the wall or align with an appropriate gang/pattress box.
-
Fixing straight to wall – drill 0.2” (5mm) hole, insert plugs and use the four screws (No.4 Pozi) provided.
Alternatively – Fix direct to a vertical 2-gang/double electrical pattress box. -
There are pre-fractured areas for cable entry on the rear of the base and pilot holes positioned on the top and bottom of the enclosure suitable for entry points up to ¾” (20mm). Drill out as necessary ensuring all swarf is removed from the box and holes have smooth edges.
-
Secure the front cover with all M4 bolts and insert security caps provided.
Clear Weatherproof Covers
These indoor/outdoor low-profile covers protect devices without restricting legitimate operation.
The versatile cover offers excellent protection against physical damage (both accidental and intentional), dust and grime as well as severe environmental conditions inside and out.
Wall Mount Cover. Part No: AGS-TGC-WM-COVER
Flush Mount Cover. Part No: AGS-TGC-FM-COVER
Contact your AGS Representative to order.
Circuit Board Terminals
- Damage to PCBs when creating cable entry points may void any warranty!
- Take care when making connections to high voltage connectors!
- Any damage attempting to remove the circuit board may void any warranty!
- All Class 2 wiring is to be installed within flexible tubing to maintain segregation between circuits!
- Wiring of different circuits shall be separated by means of routing, clamping or barrier!
- A switch or circuit breaker must be fitted, it must be accessible and marked as the disconnecting device!
- A disconnector is required and accessible for the 24V supply and an adequate overcurrent device is fitted!
- For field connections use wires suitable for at least 167°F (75°C)
- Any parts that form part of the connections/installation must have a minimum fire-retardant rating of UL 94V-2!
- Connecting both mains 120V~ and 24Vac/dc power is considered misuse – use only one power input!
- Terminals are pluggable for ease of wiring and therefore subject to misplacement resulting in a hazardous condition!
Wiring – Power Inputs
The controller requires a power supply of 100-120V~ Wired to the [POWER/LINE IN] connector using a 3A switched fused spur. Alternatively, the unit can be powered via the 24V [POWER IN] terminal. This can be AC or DC. When power is connected/live, a red LED will illuminate on the front of the controller on the AGS Logo.
Wiring – Gas Valve Outputs
Use earth terminals for gas valves not considered class II apparatus!
Connecting two valves to both mains 120V~ and 24V~ simultaneously is
considered misuse – use only one valve output!
A gas solenoid valve should be powered using one of the terminals marked
[VALVE OUT].
Terminals offer control via 100-120V~ or 24V~.
When wired to a normally closed gas solenoid valve, the TGC controller can be used to isolate the gas supply either by; pressing the Off button on the unit; when the configured time runs out or if remote emergency devices are activated.
Wiring – Remote Stop
Cable lengths wired to this volt free contact will depend on cable condition and thickness.
The Timed Gas Controller can be connected to remote devices with an open/close
circuit via the [EM STOP] volt free switch terminal.
This terminal has a factory fitted link installed (normally closed circuit)
and when open will isolate the gas supply resetting the gas supply timer.
No audible alarm will occur – only the EM Stop LED indicator located on the
front fascia will illuminate.
Selectable Automatic Timeout Switches
On the circuit board are two dipswitches used for selecting the automatic gas
shut off timeout.
The controller LED will turn yellow ten (10) minutes before the selected time
is reached and when five (5) minutes remain the buzzer will beep, and the
yellow LED will then intermittently flash.
After this time, the gas will automatically shut off until reactivated by pressing the ‘On’ sensor located on the front fascia.
Basic Operation
Isolate the equipment from all hazardous live power sources before opening the cover!
When power is supplied to the TGC controller, the LED on the logo will
illuminate Red. To turn the TGC controller off, disconnect electrical power
supply.
Status LED
The LED changes colour when the controller enters three (3) different states as follows.
- Gas On. Remains illuminated when gas is being supplied.
- 10 Minutes Remaining. The LED will turn yellow ten (10) minutes before the automatic gas shut off timeout is reached and when five (5) minutes remain the buzzer will beep, and the yellow LED will then intermittently flash. After this time, the gas will automatically shut off until reactivated.
- EM Stop. Remains illuminated when a remote stop device has been activated.
The gas supply is isolated until the emergency has been investigated, rectified, and reset. Press ON to re-enable/open the gas supply.
Basic Maintenance
Keep your gas controller in good working order – follow these basic principles.
- Remove any dust/debris from the outer enclosure regularly using a slightly damp cloth.
- Never use detergents or solvents to clean your device.
- Never spray air fresheners, hair spray, paint or other aerosols near the device.
- Never paint the device.
