Installation Steps (General Overview)
- Prepare the existing fireplace opening, ensuring it is clean and free of debris.
- Install a continuous chimney liner from the top of the chimney to the fireplace insert flue collar.
- Carefully slide the fireplace insert into the prepared opening.
- Secure the insert according to manufacturer instructions and local codes.
- Install the chosen trim kit, ensuring a snug and aesthetic fit.
- Connect the electric blower (included) and ensure it is operational.
Operating Instructions
Fueling the Fireplace Insert
- Use only dry, seasoned hardwood. Softwoods burn faster and produce more creosote.
- The firebox volume is 1.6 cubic feet. Maximum firewood length is 18 inches side to side or 11 inches front to back.
- Avoid overfilling the firebox, as this can lead to inefficient burning and excessive heat.
Starting a Fire
- Open the air intake control fully.
- Place crumpled newspaper or fire starters at the bottom of the firebox.
- Arrange a small amount of kindling (small, dry sticks) over the newspaper.
- Light the newspaper/fire starter.
- Once the kindling is burning well, gradually add larger pieces of wood.
- Close the door once the fire is established.

Adjusting Air Control
The air intake control regulates the burn rate and heat output. Adjust it to achieve the desired flame and heat. Fully open for a hotter, faster burn, and partially close for a slower, more efficient burn. Avoid closing the air control completely, as this can lead to incomplete combustion and creosote buildup.
Heat Activated Blower
The Model 21 includes a heat-activated blower. This blower automatically turns on once the unit reaches a certain temperature, circulating warm air into the room. The blower speed may be adjustable via a control knob, allowing you to customize the airflow.
Maintenance
Ash Removal
Remove ashes regularly to prevent them from accumulating and blocking the air intake. Use a metal container with a tight-fitting lid for ash disposal. Ensure ashes are completely cool before disposal.
Glass Cleaning
The glass viewing area may accumulate soot. Clean the glass when the unit is cool using a non-abrasive glass cleaner specifically designed for wood stove glass. Avoid using harsh chemicals or abrasive pads that can scratch the glass.
Chimney and Flue Cleaning
Have your chimney and flue inspected and cleaned by a certified chimney sweep at least once a year, or more frequently if you burn wood continuously. This prevents creosote buildup and reduces the risk of chimney fires.
General Inspection
Periodically inspect the door gasket for wear and tear. A worn gasket can lead to air leaks and reduced efficiency. Check for any cracks or damage to the cast iron body. Address any issues promptly.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Smoke coming into room | Blocked chimney, downdraft, wet wood, insufficient draft | Check chimney for obstructions, ensure proper air intake, use dry wood, consult chimney sweep. |
| Poor heat output | Wet wood, insufficient air, small fire, blower not operating | Use dry wood, open air control, build a larger fire, check blower connection/function. |
| Excessive creosote buildup | Burning wet wood, low burning temperatures, restricted air flow | Burn dry wood, maintain hotter fires, ensure adequate air supply, clean chimney regularly. |
| Blower not working | Not hot enough, power issue, faulty blower | Allow unit to heat up, check power connection, inspect wiring, contact service if necessary. |
