3.6 Ventilation
It is important to ensure that there is adequate air 
space around the heater to supply air for 
combustion, ventilation and distribution in 
accordance with local and national codes. See Page 
10, Section 6
.
3.7 Gas Supply
It is important that the gas supply pipe is sized 
correctly to provide the inlet pressure as stated on 
the heater data plate. The gas supply pipe and 
electrical connections must not support any of the 
heater's weight. See Page 18, Section 8.
3.8 Electrical Supply
A permanent 120 V /1 Ø/60 Hz electrical supply is 
required for the main electrical power. The heater 
also requires suitable controls in accordance with 
Page 19, Section 9.
