Regular Maintenance you can do yourself youtube

Filling with water: Connect your domestic water to the return line to the furnace using a ball valve. This makes it much easier to fill and flush the unit. Start filling the unit inspect for leaks. Make sure the ball valves on the unit are open to the return and supply. Once the green light on the control panel goes on, you’re full. Or if is simple over flows. Don’t worry this is not a problem.
Flushing your Furnace: It is very important to drain and flush your furnace each spring. To drain furnace — open drain valve and let stove empty completely. To flush — leave drain valve open and close pump valve. Add water to furnace through the return lines. Let flush for several minutes. Close drain valve and open pump valve. Refill stove and add boiler treatment right away.
Adding Boiler Treatment: This should be done every year! Allow system to burn for 2 hour and then add boiler treatment as follows. Before adding boiler treatment, be sure that the water temperature is at least 100 degrees or higher. Add the boiler treatment that came with your unit or purchased from your dealer. Add the treatment to vent (Small tube) on top of the unit.
Annual WoodMaster Maintenance: Protect your fire chamber by placing the chimney cap over the chimney during the off season, inspect all silicon caulking and make sure it has a good seal so moisture can’t enter furnace. If you have an ash auger, remove it, clean out all the ashes and scrape excess creosote from the fire chamber surface. Reinstall the ash auger. Moisture combined with ashes will eat through metal in a short time.
Bleeding the unit: Routinely pay attention to the water level light. If light is not lit, this indicates water level is low and the furnace may need to have water added. Add water until it over flows the vent pipe on top of unit. Not a bad idea to check to make sure the light is working properly. Open ball valve in back to see if light goes out or check the over flow pipe with flash light. The circulation pump will be very helpful in bleeding the air out. It can take several minutes to do this.
Firing the Unit: Once you have determined that there are no leaks and all looks good. Paper and kindling should be used for starting the fire. Build a small fire, and add wood as needed. Be sure pumps are circulating when firing the furnace. You might notice some water on the inside walls of the unit, this is normal the furnace is sweating like a cold drink on a summer day. Once the furnace has reached 180 degrees, the furnace is ready to be filled to capacity. I recommend burning cut, split, seasoned wood. Do not overfill the unit so hot coals fall out when opening the door. The best is a well controlled fire and when the wood get low, rake the ashes exposing buried unburned coals. You will be surprised those coals will heat your home all day and then some.

Caution: Do Not Burn garbage, rubber, gasoline, or any oil products. Do not use chemicals or oil products to start fire.

Ash removal, rotation and disposal: Maintain a good ash rotation. This should be done weekly. Remove ashes when the furnace is very low on wood. If your furnace is not equipped with an ash auger system use a shovel to take ashes from the front of the firebox and use a rake to pull ashes from rear of the furnace to create a level bed of hot coals. Tip Ashes are great for the garden. Ashes should be placed in a metal container with a tight-fitting lid. The closed container of ashes should be placed on a noncombustible floor or the ground, well away from all combustible materials, pending final disposal. Ashes should be retained in the closed container until all cinders have thoroughly cooled. At least 48 hours. (coals can live for a week or so) Keep this in mind when disposing ash and coals. Forest fires!
Creosote information and need for removal: When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow burning fire. As a result, creosote residue accumulates on the lining. When ignited this creosote makes an extremely hot fire. The chimney connector and chimney should be inspected at least monthly during the heating season to determine if a creosote build up has occurred. If creosote has accumulated it should be removed to reduce the risk of a chimney fire. This is another reason why an outdoor Wood Master furnace is the superior solution to heating your home.
