Kozy Heat Chaska 29 Gas Insert
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
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

Kozy Heat Gas Insert FAQs
What is a Kozy Heat gas fireplace insert?
A gas fireplace insert is a gas-burning appliance installed inside an existing wood-burning fireplace. It updates the old fireplace with a sealed gas firebox, burner system, and venting.
Can a Kozy Heat gas insert go into my existing fireplace?
In many cases, yes. Gas inserts are designed for existing masonry or approved factory-built wood fireplaces, but exact fit depends on the fireplace opening, chimney condition, venting requirements, and the specific Kozy Heat model.
Do Kozy Heat gas inserts use natural gas or propane?
Many Kozy Heat gas inserts are available for natural gas or propane. Fuel availability depends on the model and installation setup.
Do I still need my chimney?
Yes, but not in the same way as a wood fire. A direct vent gas insert commonly uses the existing chimney as a chase for the intake and exhaust venting system.
Are gas inserts good for zone heating?
Yes. A Kozy Heat gas insert can help heat the room or area where you spend the most time, reducing reliance on whole-home heating in some situations.
Do Kozy Heat gas inserts require professional installation?
Yes. Gas inserts should be measured, selected, vented, connected, and tested by a qualified fireplace professional. At all Leisure Time Inc. locations we offer the services necessary to get your fireplace insert properly installed.
