This guide walks you through framing and installing your EcoSmart Flex Peninsula Fireplace, from preparing the wall cavity to securing the appliance and completing the final setup for safe, seamless integration.
Flex Peninsula Fireplace Installation
Equipment required: Power Drill, Screwdriver, Level
1. Construct a main wall framework with the opening size shown in Table E. The base of the frame can be a solid bench/platform, which will assist in leveling up the appliance when in position.
WARNING: Three-sided appliances cannot be inserted into a one-way cavity wall, it must be a two-way cavity where the glass on all sides are free from obstructions. Do not apply pressure or materials to the glass. Triple sided appliances are designed as room divider inserts. If you do not comply with this installation instruction the wall could overheat and catch fire.
Table E: Framework Opening Sizes
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 into the framing cavity (the bottom tray can sit directly on top of the frame). The appliance is shipped with red stability bracket(s) on the open sides to keep the appliance square while in transport and during installation. Keep these brackets on while framing up the setting to assist in minimizing movement of the appliance.
4. Ensure that the back and open side edge of the appliance are flush with frame studs.
5. 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.
6. 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.
7. Remove the red stability brackets.
8. 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.)
9. Place the burner into position.
10. Remove the dust protective tape that covers the windscreen mounting slots.
11. If your appliance includes a decorative box on the left / right or both, insert the internal glass panel 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.
12. Insert the full height glass panel into the open end side by inserting the glass into the opening at the top of the appliance, and lowering it into the slots in the base until it bottoms out into place.
13. 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.
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.
14. 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.
