Operating Furnace FAQs:

  • Am I burning too much wood?

You may be. Is the wood properly seasoned? Have you cleared the firebox? High wood consumption can be caused by a number of factors.

  • Can I leave my Outdoor Wood Burner over the weekend?

You may have someone "feed" your furnace for you or you may lower the thermostat temperature.

  • Should I turn my thermostat down at night?

No, the lower the water temperature will cause the use of more wood to recover.

  • What are the critical items to operate and maintain my furnace efficiently?

1. Keep water full

2. Manage ash

3. Use water treatment

4. Use seasoned wood

5. Keep fire in the middle of the firebox

6. Clean tubes regularly

Maintenance FAQs

  • Why is water treatment important?

The boiler chemical (water treatment) that you would apply to your furnace water coats the inside of the furnace to reduce the effects of corrosion on the metal. Click HERE to order our Liquid Armor Water Treatment and other outdoor wood furnace parts.

  • How often do I need to Inspect my Chimney/Flue

Inspect chimney and flue monthly and clean as needed. Clean chimney and flue annually. Perform cleaning and maintenance only when no fire is present in the firebox and ashes are cooled completely.

  • Why is ash management important?

If the ash becomes wet it is corrosive to the metal of the furnace. If the level of ash is too thick in the water box it does not allow for efficient heat transfer to the water in the water jacket of the furnace. The temperature of the water in the jacket is used to heat your house.


  • Why am I not getting hot water?

Check that the hot water system is connected properly. Check if the heat exchanger is partially or totally clogged.

  • Why does my furnace continue to burn when it is not operating?

Check the door seal, door adjustment, and solenoid.

  • I can't find a leak in my furnace. Why am I losing water?

Outdoor Wood Burning Boilers use a non-pressurized system, this means that the existing heating system is exposed to the air. Since the water in the system can and will be warmer than the air, there will be evaporation of the water in the system. The water must be checked and adjusted at least once a month, sometimes more.
