The recommended height from the oor to the
gas unit heater base is 2,2 to 3,5 m (see Figure
2.2 p. 26 ). Installing the gas unit heaters at
heights below 2,2 m from the oor is not recom-
mended.
2.4.2.2 Centrifugal gas unit heaters
The position of gas unit heaters with centrifugal fan must
consider the position of the warm air duct. This must be
suitably sized and veried in relation to the air ow rate
and the head of the centrifugal fan (Paragraph 3.4 p.35 ).
The recommended height from the oor to the
gas unit heater base is 2,5 to 3,5 m (see Figure
2.2 p. 26 ). We do not recommend installing the
gas unit heaters at heights below 2,5 m from the
