No Ice-Device Keeps Sewer Vents Open

No Ice-Device Keeps Sewer Vents Open FARM HOME Houses 20-6-35 Here's a simple new way to keep ice from forming in sewer vent stacks. The "No Ice-Device" from Behrens Construction, Minot, N. Dak., prevents ice build-up in outlet stacks by blowing room-temperature air up into them. It's powered by a small electric fan that forces room temperature air into the stack. The unit can be wired into a thermostat so it automatically turns the fan on when the furnace starts and off when it stops, or into a timer or switch. It has a plunger-type stop that prevents sewer gas from entering the building. Sells for $87.50 plus $5 S&H.
