When to replace your Stove Glass Seals and door seals?
Your stove door seal will most likely be thermal rope which will harden and wear over time. This rope seal is vital in preventing gases from escaping and outside air entering through the gap rather than through the air intake vent which will affect the performance of your wood burner. So inspect your door seals every 6 months. They are relativley cheap & easy to replace.
Glass seals prevent gases from escaping and air entering through these gaps and can cause the glass to overheat and crack due to a rise in temperature caused by increased combustion. Inspect annually and replace if they show signs of hardening or wearing.
