The Jet Stream Extra system is mounted without additional cost – the only thing the customer needs to do is to provide the name when ordering the specific fireplace insert.

Fireplaces

 

1. Properly built fireplaces have suitably sized openings at the bottom and top of the casing ensuring a constant flow of convected air that guarantees a long-lasting problem-free usage.
