This guide walks you through framing and installing your EcoSmart Flex Single Sided Fireplace, from preparing the wall cavity to securing the appliance and completing the final setup for safe, seamless integration.
Flex Single Sided Fireplaces Installation
Equipment required: Power Drill, Screwdriver, Level
1. Construct the main wall framework with the opening size shown in Table A. The base of the frame can be a solid bench/platform, which will assist in leveling up the appliance when in position.
Table A: Framework Opening Sizes
Physical appliance dimensions should be verified against cut out dimensions BEFORE
installation begins to confirm tolerances align.

* Appliance weight includes burner/s (dry weight excluding fuel), glass charcoal and glass. It does NOT include glass charcoal for side boxes.
IMPORTANT: The framing above the appliance must be self-supporting. The appliance is not load-bearing.
2. Slide the appliance inside the framing cavity (the base of the appliance can sit directly on top of the 2 x 4 framing material). 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 minimizing movement of the appliance.
3. Secure 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.
4. Remove the red stability brackets.
5. 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.)
6. Place the burner into position.
7. Remove the dust protective tape that covers the windscreen mounting slots.
8. If your appliance includes a decorative box on the left / right or both, insert the internal glass panel/s by feeding the glass upwards into the slot then pushing down into the positioned clips.
*Decorative logs must NOT be placed directly over an open flame. They are designed to sit near heat but not over flames.
9. Install the windscreen by inserting the two ends into the 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.
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.
10. 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.
