Stove Break-In Procedure
Jøtuls are constructed of cast iron plates and sealed with stove furnace cement. Cast iron, while very durable, expands and contracts as it is heated and cooled. Cast iron construction requires the stove to be “broken-in” gradually so that thermal expansion does not occur too quickly. This seasoning process is accomplished by burning a short series of small-to-medium fires while using a stovetop thermometer to monitor temperatures. Follow the procedure outlined below.
During the break-in period, some smoke and fumes will be evident as the stove paint cures. Be sure to allow plenty of fresh air into the room to alleviate this temporary condition.
1. Fully open the primary air valve. Light a small fire of newspaper, kindling and several small splits, no bigger than 2" thick. Only allow the stove to reach a temperature of 200°F (93° C). Maintain the fire at that level for approximately 1 hour and then allow the stove to cool to room temperature.
2. Build a second fire using small-to-medium logs (2”-3” dia), allowing the stove to reach a maximum temperature of 400°F (204°C) for 1 hour.
3. Cool the stove to room temperature.
4. Build a third fire with larger diameter logs nd gradually allow the stove to reach and maintain a surface temperature of 500°F (260°C).
5. Cool the stove to room temperature. This completes the “break-in” procedure and the stove may be operated normally.
NOTE: Keep the stove under 400°F (204°C) surface temperature during any “break-in fire”, with the exception of the final one. If the temperature exceeds 400°F, move the primary air control lever all the way to the left to minimize the air supply. It is normal for the stove top temperature will continue to climb until the fuel burns down somewhat. Once the fire is out and the stove has cooled to room temperature, continue the break-in procedure. Never attempt to reduce the temperature by removing burning logs from the fire.
Be careful to avoid overfiring the stove. No part of the stove should be glowing red under normal operation. If any cast iron part glows red, you are overfiring and creating a hazardous condition which can damage the stove.
