Does this flame look OK?

I have an Eskabe DVEL 12 (propane) direct vent wall heater. When I fire it up, initially all looks fine, then after it heats up (maybe 5 minutes) it starts getting a tall lazy yellow flame near the point where the propane feeds in to the burner (which is near the pilot light assembly). I made a little video of it, which is posted here:

One other weird thing that after this yellow flame starts going, once I turn it to "pilot", the pilot flame is bright yellow for quite a while, but then eventually goes back to blue.

Is this normal? If not, any ideas on what the problem might be? Thanks.

I see that lots of people have viewed this, but so far, no responses. This isn't a complicated question---I'm just wondering if this is something that would normally be seen in a propane heater. Anybody out there with a propane heater is qualified to respond. I've never had any propane appliance before, and it looks unusual to me, but I don't know. Thanks.

I (and probably most people) don't have software on their computer to view a .mov file so I can't view the video. Upload the video to youtube or somewhere and post a link here so we can view it.

The flame looks fine blue with slight orange to red tips is a hot flame...the orange flare on the right is probably the pilot light ...and is likely much lower w/o the main flame going... if not, adjust it down.

It is normal for the pilot light to behave like this. The supply to the pilot is increased during burn it takes a while to burn off after burner shut down. This increased flow helps to prevent pilot blowout when the burner shuts down.

You really can't go the pilot's appearance with the main burner running.

totally normal. it is your specific blend of gas that is doing this. it will be different in a few days/weeks.
