Version: August 2020 3
Step 1: Unpack and ensure all components are correct and undamaged
•Appliance with 2 remote controls (one spare)
•Box of firebed mediums
•Flue kit
Step 2: Install plinth (if required)
•If the appliance is to sit on a plinth, ensure it is capable of
supporting a 200kg load.
•There is no clearance requirement for the base of the appliance.
It may safely sit directly upon combustible (eg. timber)
and non-combustible (eg. concrete) materials.
Step 3: Install appliance into cavity
•Before installation, confirm all minimum clearances
from the outside surfaces of the appliance to the surrounding
enclosure are no closer than 25mm from combustible
materials and 5mm from non-combustible materials.
•The exception to these minimum clearances is the base
and the outer 2mm steel perimeter panels of the appliance, the
base can safely sit directly upon combustible (eg. timber)
and non-combustible (eg. concrete) materials. The outer
2mm steel perimeter panels and rear air channel can safely
touch combustible (eg. timber) and non-combustible
(eg. concrete) materials.
•If a gas supply pipe has already been run to the cavity, ensure 1000mm of 3/8 soft copper tube is available
at the lower side of the cavity, as this is where the copper tube with the gas supply enters the appliance.
•If an electrical supply cable has already been run to the cavity (must be a minimum of 1.0mm 3 core cable),
ensure that the cable reaches the lower side of the cavity, as this is where it will enter the appliance.
•In order to access the fixing slots in the base of the appliance, and the gas and electrical connections, it is
necessary to first remove the glass and the burner tray.

Version: August 2020 4
Glass removal process
•Note: Glass removal is best carried out by two people.
•Carefully remove glass, which is held in place by retaining clips along the top of the glass and powerful
magnets in each lower corner.
•Remove the top retaining clips by undoing the 4mm Allen head
cap screws.
•Gently pull at the top corners in a forward motion. The glass will
tilt forward.
•In one movement gently pull the glass up and away from the appliance to break the magnetic connection.
Take care that the glass doesn't fall completely off once it’s free from the fixing magnets.
•Lift glass away from the appliance and lay flat in a safe place with insulating material facing down to
protect glass.

Version: August 2020 5
Glass installation process
•Note: Glass installation is best carried out by two people. Check all glass edges and surfaces for damage.
Do not install the glass if it is damaged. Check that the insulating material (ladder rope around the outer edge
of the glass and around the opening of the appliance) is complete and undamaged. Do not install the glass if
the insulating material is damaged or missing.
•Carefully install the glass, which is held in place by retaining clips along the top of the glass and powerful
magnets in each lower corner.
•On the back corner of each glass there are 3mm steel magnet
panels. In one movement, gently lower the glass down allowing the
steel magnet panels to catch the top front face of the magnets.
Take care lowering the glass completely down into position. The
glass will lower onto a safety switch. There is a safety switch at the
base of each glass panel.
•Gently push the top corners of the glass back into position.
•Tighten the 4mm cap screws that hold the glass retaining clips in
position.
Make sure the retaining clips sit flat onto the glass surface.

•Remove the burner tray by following the ‘Burner Tray Removal Process’in this guide.
•With the burner tray removed the electrical connections between the appliance and the wall isolation switch
can be seen, use 3 core (minimum 1mm) cable from the wall isolation switch.
•Following these connection details, using the 3 core cable that has been run at site, connect the wall
isolation switch to the appliance
•IMPORTANT: Before testing, ensure the gas valve is
turned OFF.
•The GD12 models have for each glass panel a safety
switch, at the base of each lower opening. The safety
switch turns the appliance off if the glass is not in the right
position. The safety switch will need to be held down to
complete electrical testing. It is recommended that
masking tape is used to hold the safety switch down.
•Test electrical functions by switching the wall isolation switch to the appliance ON.
•Using the remote control, switch the appliance ON, following the ‘GD12 Operating Instructions’ in this
guide.
•The fan will start and after approximately 25 seconds, the pilot will spark. Because the gas supply is turned
off, the pilot will spark for approximately 25 seconds then automatically switch off.
•Using the remote control switch the appliance OFF, following the ‘GD12 Operating Instructions’ in this
guide.
•Switch the wall isolation switch to the appliance OFF. Electrical testing is complete.
•Install the burner tray by following the ‘Burner tray installation process’ in this guide.

•Particular care should be taken when placing the chosen firebed mediums into the burner tray. Failure to
place the medium correctly may result in the fire performing inefficiently.
•Open the firebed cardboard box and identify firebox mediums.
River Rocks option has two firebed mediums:
Vermiculite –3 bags
White rocks –large and small
Beach Driftwood option has three firebed mediums:
Vermiculite –3 bags
White rocks –large and small
Driftwood –large and small
Forest Logs option has three firebed mediums:
Vermiculite –3 bags
White rocks –large and small
Logs –large and small

Version: August 2020 20
How to lay Vermiculite
•In order to access the burner tray, it is necessary to first remove the glass.
•Note: glass removal is best carried out by two people.
•Follow the ‘Glass installation process‘ in this guide.
•Lift glass away from appliance and lay flat in a safe place with insulating material facing down.
•Beginning in the middle at the back of the burner,
carefully empty the bags of vermiculite into the
burner tray.
•Ensure not to spill any vermiculite in cavities
in front of and behind burner tray.
•Do not pour vermiculite directly into burner slots.
•Fill area behind burner up to top of burner tray.
Use hand to spread out and push under burner.
•Fill up area in front of burner and gently pat
down vermiculite to ensure it is spread evenly
throughout the burner tray.
•Using a small Allen key (or similar), remove any
vermiculite that may have fallen into burner slots.
