Not sure if this applies to the intake but it might, better safe than sorry. Use at least 3 screws at each joint and whatever necessary to connect to the stove and thimble, it's not uncommon to get a minor "explosions" or a "puff back" usually during loading. Not much you can do at thimble but as long as the rest of it is secure and solid that shouldn't matter. It's very possible it will blow the pipes off the stove, and if you don't have them at joints they can come apart. Other than the safety issue you'll have a mess on your hands. Pipes coming off that have not been secured properly have happened. See here for more information: Minor Explosion In Coal Stove
As long as the flue pipes are properly secured it's non issue other than maybe your underwear or eyebrows if it happens when door is open.
The other question is if that is hand fired stoke why does it have intake at all? Such a large volume of air is not needed except maybe to get it started or if you really wanted to get it ripping. During normal operation a hand fired stove is going to need very little air. Is there a handle up front to control that?
