Anyone have this happen with your Woodmaster?

[Rassmo]

I'm new to the forum and was just wondering if anyone else has ever had this happen with their Woodmaster OWB. Last season in the middle of the winter I went out to check the fire and the water temp was in the 190's and rising. The fan was not blowing but there was orange flames belching out of the chimney at least a couple feet. I went opened the door and the flames were roaring big time. Couldn't figure it out. Went inside and turned the bathtub water on full hot. (I have a heat exchanger and wanted to reduce water temp returning to OWB.) Went back out to investigate. Opened cover on the door to check damper and blower. The electric magnet that opens damper on the burn cycle was stck open so fire was still getting plenty of air. Quickly popped it back down to close air supply. Sprayed WD-40 on magnet and worked it up and down several times and didn't have the problem again all season but gave it some more WD-40 last week before stating to burn for the season. I'll probably spray it again mid-season just to be sure. The water temp got up to 203 before starting to fall.

Wow! New to the OWB so no I haven't had it happen, but thanks for bringing it up it will be something I'll definately check if I ever have that type of problem.

I have a CB 5036 and a few times last year a piece of creosote or a coal popped from an ash log and kept the damper open and it boiled the stove over. This is the only thing I could think of because when I went out there the damper was closed back down. It takes a while for the temp to come down when it's that high. I turned on the bathtub, kitchen and bathroom sinks and the blower for the furnace and it took 2 hrs to get back down to 180.

Sometimes it is a combination of heat formed varnish from evaporated oil that collects dust that gums things up. Another shot of a light oil like WD 40 loosens it temporarily but it comes back worse. Sometimes best to clean all lube off with a degreaser, blow dry and spray on a graphite or moly dry lube. That might be tricky to do safely with the fire on but just a thought. Make sure it is not some bent or distorted part that is causing the hangup.
Not directly connected but have had to use the same treatment where extreme cold was causing lubrication to gum up the works. Firing pin strikers!

The dude across the street from me has a woodmaster. One night I looked out and saw some serious flames shooting out the pipe. Looked like a rocket engine. lasted about 20 secs and petered out.

Never had that happen but it is something to check each year. Wife left the door craced open once and the water temp was up to 200. My dealer told me to check each year for bees nest in by the fan as that may cause problems. I burn all year so I don't have any bees.

Had something simular happen to my indoor coal boiler that is in my detached garage. Basically same issue with the combustion blower. I was at work and the wife called me at 3am and said it was 90 deg in the house. ( heat dump safety dumps the excess heat into my house) She looked out at the boiler and the water was a whopping 240 deg!!!! I told her to put the fire out in the boiler and she said "Hold on until i get the hose" NO !!!!!!!!!! luckily she heard me yelling over the phone and then I told her ASHES ONLY ON THE FIRE !!!

I did learn a few things from this experience.

1. ALWAYS keep some ashes close by
2. Aluma Pex will/can handle 240 deg water
3. Coal really does burn super hot !!!
