Page 7: Ducting To The Outside
INSTALLATION NOTES: 1) When selecting an installation option, consideration should be given to the increased electrical consumption of the furnace fan. The way that your Heat/Energy-recovery ventilator is installed may make a significant difference to the electrical energy that you will use. To minimize the electricity use of the Heat/Energy-recovery ventilator, a stand-alone fully ducted installation is recommended. -
