We present observations towards the Class I protostar EL 29 of the CO J = 6 → 5 and J ≥ 15 transitions obtained with JCMT and ISO LWS respectively, and of five H_2 rotational lines obtained with ISO SWS. The simultaneous analysis of these observations reveals the presence of a warm gas component at about 170–250 K, ~550 AU in size, and whose density is ≥ 10^6 cm^(-3). The mass of the warm gas is ~8-24 x 10^(-4) M_⊙. These values compare extremely well with the predictions of the temperature and mass of the flaring disk surrounding EL 29, probed by the dust continuum. We propose that the observed FIR CO emission originates in the super-heated surface layer of the disk of EL 29 and discuss its characteristics. We find that the CO abundance in...
