An oven (1) for baking foods having a baking cabinet (2), at least one door (3), a plurality of burners (4), a plurality of annular heat exchange tubes (6) for receiving in an annulus (7) at an intake end (8) combustion gases (5) from the burners (4), a flue (9) for conducting the combustion gases (5) out of the oven (1), and a blower device (11) for recirculating air from within the baking cabinet (2), over the heat exchange tubes (6) and back into the baking cabinet (2). In the improvement, a first bracket (20) is removably attached to the oven (1), a second bracket (21) is attached to the oven (1) and spaced a distance from the first bracket (20). A plurality of annular heat exchange tubes (6) are disposed between the brackets (20, 21) with the intake end (8) of each tube attached to the second bracket (21) and the discharge end (10) of each heat exchange tube (6) attached to the first bracket (20) so as to form a removable rack (25) of the heat exchange tubes (6). Each heat exchange tube forms a curved configuration such that the length of the curved configuration of each heat exchange tube is greater than a distance (X) between the brackets so that each heat exchange tube is independently free to expand and contract with heating and cooling of the heat exchange tubes without significant force being placed on the brackets.
