Fireplace insert must be surrounded with an incombustible casing, which is equipped with convection air inlets and outlets (for convection air heating and cooling the insert)
Casing can be made of:
- Light, heat reflecting material which stays colder on the surface and increases the temperature of convection air. (Peak power is high, but distributes heat only for a short period of time)
- Heavy, heat storing material which becomes warm on the surface and prolongs the heating period. (Peak power is lower, but distributes heat for a much longer period of time)Both casing materials are available from us, with or without installation.
