End of Season Wood Boiler Shutdown and Cleanout

Crown Royal Stoves will provide long life if maintenance is performed correctly. The most important step is cleaning out your boiler once a year at the end of winter and the heating season.

1. One last hot fire: throw cardboard or other fast-burning material into the stove and turn up the aquastat to get a full, long burn. This softens any creosote for the next step.
2. Shut off the boiler and disconnect power to ensure your safety during maintenance.
3. Allow the boiler to cool to a point you can safely work, and use gloves, a mask, safety glasses, and other protective gear. Be careful not to touch any metal that may still be hot.
4. Clean the primary burning chamber and cleanout areas: using a scoop and the provided hoe, remove ash and soot from the firebox, air passages, and heat exchanger tubes — scraping until bare metal is seen. On a Pristine, this may require removing the side panels, the square back air chamber, or the top refractory brick to clean the secondary-burn passages. On a Multipass, give extra attention to the sides and above the water exchanging tubes, and clear ash buildup behind the ash pan.
5. Inspect and clean the chimney for creosote buildup or debris, running a chimney brush down it if needed. On a Pristine, actuate the front turbulator cleanout lever one more time and clean the top section by the blower motor. On a Multipass, clean the top heat exchanger including between the 1st and 2nd heat exchangers and out into the chimney.
6. Inspect the door gaskets and seals, replacing any worn-out or damaged gaskets, and adjust the doors as needed to keep proper sealing force.
7. Wash the outside of the stove — car wash soap in water works well.
8. Corrosion protection: spray the firebox with diesel or a 50/50 mix of diesel and used motor oil for extra protection during the off-season, when ash buildup mixed with moisture is hardest on the stove.
9. Water sample: the off-season is a good time to remember to send in your annual water sample to Crown Royal Stoves.

Follow proper safety precautions throughout. If you're unsure about any step or lack experience, consult a professional technician or contact your dealer or the manufacturer for guidance.
