The season is here for alternative heating.
Be extra careful when using your heating system using wood or other material for burning. Many people use wood for alternate heat and it is usually safe.
Be sure your flue is clear of soot creosote build-up. This material in the flue can ignite and cause a flue fire which can cause a hot fire somewhere in the flue. Devices or a service company can be used to clean your flue.
Have an area around your loading door that is tile or fire brick so when the door is open, sparks will not land on flammable surfaces.
Regularly check the furnace for proper seals on all doors and flue connections to be sure smoke is being vented outside.
Be safe when saving money by burning wood.
