Installation and Fit
Keep the cassette’s air intake and mist outlet open and provide access for filling, drainage and service. Confirm whether the supplied unit is automatic-fill or manual-fill before planning plumbing. Automatic-fill models require the appropriate supply connection and a leak check; manual-fill models use their designated filling arrangement. The nominal catalog SKU does not identify that configuration. Have the electrical supply matched to the rating label. Use the manual’s finished-opening dimensions for the exact model, not its overall outer-edge dimensions.
What’s Included
Fireplace, remote control, decorative media supplied for this series, and manufacturer documentation when available. Confirm framing, electrical, ventilation, and clearance requirements before installation.

Common Questions
Can the flame effect be used independently?
Yes. Mercury is designed as a decorative water-vapor flame system rather than a conventional heater.
How should I choose a size?
Use the listed overall dimensions for planning, then verify the current manufacturer installation instructions before framing or ordering finish materials.
Does it include smart control?
Yes. This series supports smart app control in addition to the included remote.
Does Mercury need a permanent water connection?
That depends on the supplied configuration. The manual distinguishes A automatic-fill models from M manual-fill models. A models use the specified direct-water connection; M models do not use those plumbing steps. The catalog SKUs omit the suffix, so confirm the configuration before ordering or planning services.
How much electricity does Mercury use?
The linked manual does not provide a verified wattage for each model, so a numerical hourly cost cannot be confirmed here. Once the rating is confirmed, divide watts by 1,000 and multiply by operating hours and your electricity price per kWh. Do not use a 1,500W electric-heater estimate for this decorative water-vapor cassette.
