Installation
Typical Application & Location
Installation must be in accordance with the recognised standards of the
appropriate authority in the country concerned!
Access to the interior of the device, when carrying out any work, must only be
conducted by trained personnel!
Before carrying out any work ensure local regulations and site procedures are
followed!
Isolate the equipment from all hazardous live power sources before opening the
cover!
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!
-
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!
Internal Fuse: Anti-Surge 3.15A 250V ∼
Wire Rating Min. 18AWG Tinned Copper @ 167°F / 75°C 
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
A gas solenoid valve should be powered using one of the terminals marked
[VALVE OUT].
Terminals offer control via mains 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.
| S1| S2| Gas Supply Timeout
---|---|---|---
O| O| = 30 Minutes
X| O| = One (1) Hour
O| X| = Two (2) Hours
X| X| = Three (3) Hours
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.
