General Information
The AMACO ® AH-10 High Fire Kiln has a maximum attainable temperature of Cone 10 (2381ºF, 1305ºC). The AH-10 is available with
manual control switches or the Select Fire Computer Control for precise control, convenience, and consistent results firing after
firing. During every firing, pyrometric cones should be placed in the kiln so that they can be viewed through the peephole(s).
This booklet contains a wiring diagram for the AH-10 kiln, Select Fire Controller (single and three phase) and a parts list with accompanying
drawing for the AH-10 and Select Fire. Before installing the kiln, consult these diagrams for recommendations on electric
service, fuses, etc.
Also included with this booklet is an AMACO ® Electric Kilns Installation/Operation/Maintenance manual, which includes important
information about selecting a location for your kiln, firing guidelines, and do-it-yourself instructions for replacing elements, plus
complete programming and operating instructions for the Select Fire Controller.
Operating Information for Manual Models with Kiln-Sitter ®
The Amaco ® AH-10 high temperature kiln is equipped with a fused safety switch box and three toggle switches. A pilot light indicates
when the kiln is operating.
Close kiln door and latch securely before firing. Turn safety switch to “ON”, place the appropriate cone in the Kiln-Sitter ® , and push
the plunger button. NOTE: If the kiln is equipped with a KilnVent, it must be turned on prior to firing.
The toggle switches operate as follows:
LOW: Turn on any switch
MEDIUM: Turn on any two switches
HIGH: Turn on all three switches
The time required for firing will depend on the temperature to be attained, the number of objects being fired, and electric current
fluctuations. Approximate cycle times are as follows:
LOW: approximately one hour
MEDIUM: approximately one hour
HIGH: until desired temperature is reached
When firing time has been completed, turn off all switches and allow the kiln to cool overnight. If glazed pieces are removed from the
kiln when the pieces are too hot, crazing may result due to sudden cooling. NOTE: Kilns equipped with a KilnVent will cool faster.
Installation of Kiln
Place kiln at least 18 inches from any existing wall at the sides and back. Connect kiln to an electric circuit which corresponds to that
stamped on the kiln name plate. No. 6 gauge wire or larger should run from the power supply to the fused safety switch box on the
kiln. 45 ampere fuses are required.
