We present 1.2 mm continuum images and spectral line observations of CO(1--0)and SiO(3--2) rotational transitions of the recent nova V4743 Sgr. The nova isdetected at 1.2 mm showing a variable millimetre emission. Only upper limits ofT_A* = 0.06 K for CO and T_A* = 0.03 K for SiO could be derived. We discuss theresults in terms the nature of the millimetre emission favouring dust from aphase before the recent outburst as the likely radiating source. We alsocomment on the possibility of free-free emission from the ionised shell as thesource of the measured millimetre radiation.Comment: Latex, 4 pages, 3 figure
