Whether you’re recessing a linear electric unit, dropping an ethanol burner into a custom niche, or hanging a wall-mount model, this step-by-step checklist covers clearances, framing, wiring, ventilation and inspection tips for a code-compliant, trouble-free install.
| Unit type | Side clearance | Top clearance | Bottom clearance |
|---|---|---|---|
| Electric (recessed) | ½ in (ventilation channel) | 2 in | 0 in* |
| Ethanol burner in niche | ¾ in fireproof shim | 3 in | 1 in air gap |
| Water-vapor cassette | 1 in | 4 in (for mist exit) | 2 in |
| Vent-free gas log set | Use firebox walls | Damper fully open or removed | Grate clearance per manual |
*Keep insulation or vapor-barrier fabric away from rear vents.
Mount the TV so the bottom edge is ≥ 8 in / 200 mm above the top heater outlet (electric) or use a mantel shelf as a heat deflector. For recessed electric units with front vents, this clearance drops to 4 in.
