Bottom Air Inlets and Panel Cooling: Ventilation for SXRX and SXKT

A neat stone surround can conceal an important installation detail: where does air enter beneath the burner? Bioethanol fireplace ventilation needs a connected air path, not simply a decorative opening. SXRX and SXKT both require bottom intake, with the exact arrangement confirmed against the supplied installation drawing.

Start with the airflow route, not the grille

A bottom air inlet may be concealed beneath the platform or incorporated into a visible lower grille. Either approach depends on a continuous route to the intended ventilation openings. A large grille cannot compensate for a blocked space behind it. Stone, insulation, trim and items stored inside the enclosure must not close the required passage.

Ask the installer to confirm the inlet location and usable free area for the actual configuration. The frame size of a grille is not the same as its airflow area. Photos illustrate an approach; they are not dimensioned installation instructions.

Why SXRX and SXKT need bottom intake

Internal cooling

Air entering beneath the appliance supports ethanol fireplace cooling by helping internal heat dissipate through the intended route. SXKT documentation also identifies an internal fan/cooling path that must remain clear. The shared ventilation principle does not make the two series’ internal designs or opening requirements identical.

Combustion air supply

According to SXFireplace’s installation guidance, bottom intake supplies combustion air and supports normal flame appearance. The aim is a suitable air supply, not the strongest possible airflow. Do not use a fan or an air-conditioning outlet to push air across the burner; excessive draughts can disturb the flame.

Panel heat dissipation

The ventilation openings beside the burner trough help cool the panel. Keep both sides clear of decorative pieces, adhesive and dust accumulation. Do not fill, cover or modify these openings when fitting a surround. A restricted enclosure should be reviewed with the installer or SXFireplace, rather than corrected by altering the burner.

Room ventilation is a separate requirement

SXRX fireplace ventilation and SXKT fireplace ventilation include the appliance’s own air paths, but an enclosure inlet does not replace room ventilation. Follow the specific manual and local installation requirements. Any extraction arrangement also needs professional assessment so it does not pull flames towards the panel or interfere with their direction.

A short pre-use check

• Trace the lower intake through to its intended destination.
• Check that underside, panel and burner-trough openings remain unobstructed after finishing.
• Remove coverings and construction debris, then arrange supervised commissioning.

Designing a built-in surround? Review the SXRX smart bioethanol burner or SXKT smart bioethanol burner, then share the enclosure drawing with SXFireplace. Confirm the air route before the stonework or decorative panels are closed.
