    Installation As A Category I Appliance General The GS Series humidifiers have a fan-assisted combustion which operates with a non-positive vent static pressure when installed with the appropriate vent diameter. Category I appliances must be vented vertically or nearly vertically (see Figure 7, 8, 9, 10 & 11).
  • Page 21 45° elbow equals 5'. The vent run should be as direct as possible with no more than 6 elbows in the system. Contact Condair technical service if you have any questions This category installation may not be common vented with any other natural draft gas appliance or power assist appliance.
  • Page 22 The vent terminal must be installed in the same atmospheric pressure zone as the combustion air inlet of the humidifier. If this is not possible (as in cases of positive or negative room pressures) the humidifier should be installed with the sealed combustion or direct vent option. 19 | GS Series Installation...
