2.4.2.3 Vertical downow gas unit heaters
A minimum distance of 1 m from all sides is required
around the vertical downow gas unit heater.
Table 2.1 p. 27 shows recommended minimum and
maximum heights for installation and the air jet range to
the oor, depending on the actual height of the gas unit
heater from the oor (indicated with H).
For vertical downow gas unit heaters, the louvres
of the delivery grille must be in the fully open po-
sition.
