What sizes does the box come in?

The Stove Box is available in four fixed sizes and is supplied flat pack. If depth is a problem the SB1 and SB2 now comes as an adjustable option. The following kW's are advisory recommendations based on our experience over testing our installations in a 5 year period.

  • SB1 for use up to 8kW - Fixed size and adjustable
  • SB2 for use up to 5kW - Fixed size and adjustable
  • SB4 for use up to 6.5kW - Fixed size
  • Blazer for use up to 9kW - Fixed size

All the boxes are ridged, comprising of 2 sides and a rear panel that fix to the interior of the box to give a decorative finish also protecting the box.

We have also introduced two other boxes that are adjustable in depth approx 100mm (4") for when installing into a smaller breast when depth is an issue.

The stove box must be fitted to meet building regulations.  The appliance must be fitted by an approved installer. Do not fit a stove with a higher kw than suggested. The stove box cannot be fitted without a fire resistant interior.
