whitfld adv II

May take awhile for someone to get back to you. After supper on some stoves as this is a older stove with fewer of them surviving.

A very high orange flame sounds like bad combustion. When was the last time you cleaned the stove? Please describe how you cleaned it.

Did you remove the combustion blower and clean it out, clean out your venting system? You should also remove the ash trap behind the firebricks and clean out the air passages behind those.

The high flame doesn't concern me so much as your description of the flame being orange. An orange flame tells me you have a combustion issue, the large amount of pellets in the burn grate would also be directly related to that. The stove just isn't burning them fast enough and they are building up and leading to a huge flame.

chevelle, I have the same stove as you, if it is clean, try adjusting your draft on the left side of the stove, pull it out to increase your draft you shouldn't need to pull it out much 1/4" at a time you should see the flame getting lower and a nice bright yellow, the pellets will start to dance. If I open this all the way out I can blow the burning pellets right out of the pot.

Have an old Whitfield Quest (one of two stoves in house). Believe your problem is as others describe - not enough air. If adjusting damper doesn't resolve it you almost certainly need to clean stove exhaust behind firebricks. Will need small hose on good vacuum, possibly bottle brush to do this. If really bad may need to go in from exhaust side. Read about "leaf blower trick" in other threads. Slow, orange flame = poor quality, air starved flame normally caused by constricted exhaust if damper is open.

on low (1) there is a 45 second delay between auger moves. also check the the air intake for blockage. there is a good link on here for how to clean the hidden ash traps on a whitfield. also use a potatoe brush to get the ash buildup on each side of heat exchanger. (can be challenging)
