For some kilns, a high firing may take a little longer. The insulation value and the number of air leaks in the kiln also determine the length of the firing. (L\u0026amp;L NOTE: We have seen vents overpower smaller kilns - so it is important to adjust the amount of venting in some cases. On the other hand an example of an e23T 7 cubic foot kiln firing an 85 pound load on Fast Glaze program to cone 8 took 7 hours and 4 minutes with a vent on and 6 hours and 24 minutes without a vent.

(With the special “Multi-Mounting Bracket” the vent motor may be mounted on the floor or a wall with the outlet pointing up and then connected to an existing vent system or 4” wall outlet). The Bypass Collection Box mounts to the kiln either on the side of the bottom kiln section, or underneath the kiln on the kiln stand. (Jupiter and Easy-Fire kilns have studs on the stands to accept this box). It covers holes drilled through the brick. The blower is then connected to the Bypass Collection Box with the flexible aluminum duct, and the blower is plugged into a 120 Volt receptacle for operation.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\" data-mce-style=\"font-weight: bold;\"\u003eNEGATIVE PRESSURE\u003c\/span\u003e \u003cbr\u003e When operating, the L\u0026amp;L downdraft kiln vent system creates a negative pressure (partial vacuum) in both the Kiln and the flexible aluminum duct, so that fumes are pulled out of the kiln as well as out of the flexible duct. No taping of joints is necessary (although it is OK to do this). Should a leak develop in the duct, air will be sucked into the duct rather than blown out of it.

Holes may be drilled in the lid brick at any time if later found necessary. If you decide to drill holes in the lid start with a 1\/4” diameter hole drilled about 4 inches in from an edge of the lid (and then add other holes as necessary in the back of the lid and then on the sides). BE SURE NOT TO DRILL ANY HOLES WITHIN 6” OF THE THERMOCOUPLES.
