My stove has 3 secondary burn tubes, each one has a different number of holes. The tube with the fewest number of holes is in the rear, the tube with the most holes is in the front. The front tube rarely burns off gas. It seems like if it was reversed, it would be more efficient and allow it to burn off more gas. Are mine arranged wrong?
Don’t know what kind of stove you have, but are there air wash holes or a control for such above the door… and perhaps on nearly the same plane as your forward most 2ndary tube? Would it be possible (if you do have air wash) it’s open too much and interfering with touch off of gasses there? I don’t know, just wondering out loud.
You can look in the manual or look up replacement tubes for your specific stove. They are often sold individually as well as in sets.
Really the stove seems to burn good, I'm just questioning the arrangement of the burn tubes. I called the manufacturer today to see what they had to say, and after about 45 minutes talking to customer service, they didn't have an answer. It just seems like the tube with the most holes should be in the back to burn more gas, but then again I don't know the science behind it. Eric I have a Pleasant Hearth LWS-127201. It does have an air wash, with the control above the door. The forward most tube is about an inch above the air wash holes, very close to the same plane. I'm new to the world of wood stoves, but I do tinker with it to learn how it responds. Even when it's really gassing, the front tube rarely sees action. If I knew a wood stove would fascinate me so much, I would have invested in a better one. Maybe I'll sell this one and do that. Dave_in_abq I wish I would have seen your post before I called customer service, or I would have asked about part numbers. Oddly the manual doesn't even list a part number for the the burn tubes, or the baffle....
Yup, Drolet even mentions how many holes. The more I learn about wood stoves, the less I'm impressed with my stove, and much less with the support...
I was researching burn tubes for durability and how they're attached in the stove for a model I was interested in. I foud the info i needed on the spare parts order page. Seems many (if not most or all) stoves have more holes towards the front. I would have guessed back too. Which stove do you have?
It's odd they don't list the burn tubes, or the baffle. The tubes are removable, they're only held in place with a cotter pin.. If I have to replace one, I'll buy a new stove!
Your forward most tube is likely firing less because the other tubes have already burnt most of the readily available wood gas as it moves up and forward on its way out. Aaaand the forward tube is at the end of the secondary air supply route on many tube equipped stoves. My 2 cents worth I could be off in this estimation also as I have zero time with that exact stove make/model.
