The Kozy Heat Chaska 29 is a compact gas fireplace insert engineered for one specific job: turning the smallest existing masonry fireplaces — including older home fireplaces and mobile home installations — into clean, efficient modern gas units. With a fireplace opening requirement of just 29-1/2 inches wide and 15 inches deep (the smallest in the entire Kozy Heat insert lineup), 30,000 BTU/hr of heating power, three media options (Log, Rock, or Glass), and a standard 75 CFM blower, the Chaska 29 fits installations no other Kozy Heat insert can accommodate. The Smallest Gas Insert in the Kozy Heat Lineup The Chaska 29's defining feature is its compact form factor. Many older homes — especially pre-1950s construction — have masonry fireplaces with openings 30 inches wide or narrower. Most modern gas inserts (including the Kozy Heat Chaska 34 and Nordik 34i) require fireplace openings 33+ inches wide. The Chaska 29 fits cavities the others can't — including small home library fireplaces, compact bedroom fireplaces, and mobile home installations where no other Kozy Heat insert is approved. If you've measured your existing fireplace and discovered it's too small for standard gas inserts, the Chaska 29 was specifically engineered for your situation. The Chaska 29 isn't just a smaller version of the Chaska 34 — it's a purpose-built compact insert with its own dedicated feature set. Standard features included with every Chaska 29: 30,000 BTU/hr input (Natural Gas or LP) — substantial heat output for a compact insert, well-matched to smaller rooms Standard 75 CFM blower — fan kit included as standard equipment (not an upgrade) Refractory brick lining — traditional brick interior included 3-inch co-linear direct vent — sealed combustion system runs through the existing chimney SIT ProFlame 2 controls (IPI configuration) — proven gas valve technology with full-function remote Ember bed light kit (IPI configuration) — included for realistic glowing ember effect Multiple screen front options — design customization available at order Custom Kozy shrouds available — integrate the insert with your existing fireplace surround Bedroom AND mobile home approved — unique combination in the Kozy Heat insert lineup Canada P-4 approved — efficiency rating recognized internationally Will the Chaska 29 Fit Your Fireplace?
