There should be a cotter pin at the left end of the secondary tubes.

I climb on the roof and go top down. But others go bottom up. Here is a handy tool some people like: Amazon product ASIN B0010H5JXA

If there are no cotter pins, the tubes may come out like this

The Boston is a very nice stove. Tube removal and diagrams are in the manual. Be sure to mark the tubes first so that they get reinstalled in the right position and location. The front and the rear tubes are different from the middle tubes.

Removing Air Tube: If a secondary air tube needs to be removed, place a screwdriver (any style except flat head) into one of the air holes and tap it with a hammer/mallet to the left until the right end of the tube is freed. To install a secondary air tube, reverse the above instructions.
