Type of Vent: Downdraft - pulls air from the bottom of a kiln to ventilate fumes from the kiln under vacuum. Vents kiln fumes to the outside. The Vent-Sure downdraft ventilation system produces better firing by promoting higher temperature uniformity in the kiln - up to a 1/2 cone improvement.
Voltage and Amperage: 120 Volts at 1.37 Amps. On/Off Switch and Cord: Switch on six foot cord (120 volt models only).
Blower Mounting: Blower is normally mounted on the wall with discharge through a 4” round opening. (See Options below for optional Multi-mount bracket). This keeps the heat of the kiln away from the motor (for long motor life) and keeps the motor vibration away from the kiln (which can cause ware to move, damage to the kiln, and misfiring of cones on a kiln sitter). Although the vent motor normally discharges right through the wall it is mounted on, use of 4” duct can extend this distance 60 feet (horizontally or vertically) with up to four 90 degree bends.
Duct Work: 15 Feet of 3” flexible and expandable duct is included along with necessary hose clamps. Longer lengths or lengths of 3” stove pipe can be used as well.
Capacity: The blower vents up to 130 cfm (cubic feet per minute). This will handle up to a 20 cubic foot kiln (and usually larger) or even two separate kilns. More than one vent can be attached to larger kilns. Vent Control: A vacuum bypass on the kiln bypass/collection box adjusts the amount of venting from the system.
Application: The Vent-Sure is designed to be used on almost all L&L kilns.
Warranty: Limited 3 year warranty. (hotkilns.com/warranty).
UL Listing: The Vent-Sure is c-MET-us listed to UL499 standards for use with Easy-Fire, Jupiter, Liberty-Belle, and DaVinci kilns.
It is MET-us listed to UL499 standards for use with Hercules and Easy-Load kilns.
