Description
The Kratki JAS is a compact, good-looking wood insert for homeowners who want a built-in fire with a clean, modern face. Its white Accumote lining reflects the flames, so even a small fire looks bright and lively, and the glow carries on when only coals are left. Made in Poland, it is a popular way to add a proper closed fire to a feature wall or an old hearth.
Kratki JAS Insert Features
Bright, reflective firebox
The combustion chamber and baffle are lined with Accumote ceramic panels. They protect the steel housing from warping, raise the inside temperature for a cleaner burn, and hold heat after the fire dies down. They also bounce hot air onto the glass, which helps keep it clean.
Strong steel build
The body is 4mm boiler plate steel, so it handles years of hot fires. At 61 kg and 38.2 x 72 x 56.5 cm, the kratki jas insert is light enough for most walls and simple to build in.
Controlled burning
Primary and secondary air controls let you start the fire quickly and then settle it down. An air wash system runs air over the glass, and the chamber takes standard firewood lengths.
Flexible output
Output runs from 3.3kW to 9.9kW, so this insert fireplace can tick over gently or work hard on a cold night. The flue leaves from the top at 150 mm.
Is the Kratki JAS right for your home?
Kratki gives it a heating area of about 66 m2, which suits a small to medium lounge with a standard ceiling. For a larger room, ask about bigger models in our Kratki fireplace range, or read our Kratki buyer’s guide.

Kratki JAS FAQs
What size logs fit the Kratki JAS?
It takes standard firewood lengths for a firebox of its size. We will show you the usable depth when we measure up. Use dry, seasoned hardwood for the best heat and the cleanest glass.
Is a kratki fireplace hard to maintain?
Not really. Empty the ash regularly, wipe the glass when cool and have the flue swept once a year. The Accumote panels and air wash do a lot of the work of keeping the glass clear.
