This guide walks you through framing and installing your EcoSmart Flex Island Fireplace, from preparing the wall cavity to securing the appliance and completing the final setup for safe, seamless integration.
Flex Island Fireplace Installation
Equipment required: Power Drill, Screwdriver, Level
1. Construct the framework with the opening size shown in Table F. The base of the frame can be a solid bench/platform, which will assist in leveling up the appliance when in position.
WARNING: This four-sided appliance cannot be inserted into a wall structure. It must be installed on a separate framework securely anchored to the floor. Do not install on moveable or weak structure. The top part of the appliance should be installed on framework secured to the ceiling and aligned with the bottom frame. Four-sided appliances are designed as wall divider inserts. If you do not comply with this installation instruction, the structure could overheat and catch fire.

Physical appliance dimensions should be verified against cut out dimensions BEFORE
installation begins to confirm tolerances align.

IMPORTANT: The framing above the appliance must be self-supporting. The appliance is not load-bearing.
2. Remove the extension flange from the firebox so that both sides are the same height. This will help make sliding the firebox into the frame easier. Pay attention not to lose the screws, they will be needed again when the flange is re-installed.
3. Slide the appliance inside the framing cavity (the bottom tray can sit directly on top of the frame). The appliance is shipped with red stability bracket(s) installed on the open side(s) to keep the appliance square while in transport and during installation. Keep the bracket(s) on while framing up the setting to assist in minimising movement of the appliance.
4. Align the flange extension panel with the threaded holes on the appliance. Screw it into place using the included screws (bottom row onto appliance, top row onto framing material) to secure it into position.
5. Fix the appliance to the framework with screws using the existing mounting holes on the appliance flanges. Make sure that the appliance is level before securing it in place.
6. Remove the red stability bracket(s).
7. Complete the construction by finishing the wall paneling around the appliance. (See section on FINISHING INSTRUCTIONS and ensure that you fully understand where non combustible materials must be used.)
8. Place the burner into position.
9. Remove the dust protective tape that covers the windscreen mounting slots.
10. Install the windscreen by inserting the two ends into appropriate slots in the appliance. Use a small amount of pressure to push the windscreen in place until it bottoms out into the hidden glass clips. Repeat the same for the back side windscreen and if your appliance includes a decorative box on the left / right or both.
*Decorative logs must NOT be placed directly over an open flame. They are designed to sit near heat but not over flames. Add only one set of decorative logs to this model style.
WARNING: The glass used is toughened glass - which means it is stronger than normal glass. Importantly, even though it is stronger, toughened glass still has weaknesses. The corners and sides are specific pressure points where it is more fragile and can break if care is not taken. Glass breaks into many small pieces. Take care to avoid cuts. We recommend you wear protective gloves when handling glass.
11. Spread the glass charcoal evenly around the appliance tray.
CAUTION: Make sure the burner lid is closed. Keep the glass charcoal away from the burner flange to avoid glass charcoal from accidentally going into the burner chamber. Be careful not to scratch the burner.
