Commercial Kiln Warranty

POLICIES POLICIES Home> Policies> Commercial Kiln Warranty Commercial Kiln Warranty REV: 2/15/2025 Limited Two-Year Warranty Definition of "Commercial" Commercial Kilns are kilns used for industrial ceramics or other industrial processes as opposed to kilns used for hobby, school, or professional ceramics and pottery. This warranty is also specifically for Easy-Load and Bell-Lift kilns. Specifications Commercial Kilns are warranted by L&L Kiln Mfg., Inc. ("L&L") to meet all quoted specifications unless any subsequent changes to those quoted specifications made by the Buyer are accepted in writing by L&L. Two Year Term Commercial Kilns are warranted to be free of defects in material and workmanship for two (2) years after the date of shipment, with the following exceptions. Limitations and Exclusions Controls and Subsystems L&L warrants Bartlett Controls (which include the DynaTrol and Genesis). All other controls are warranted by their manufacturer under separate warranties and are not L&L's responsibility. NOTE: L&L will act as the intermediary in resolving any claims under separate control and component warranties, but the determination of the original manufacturer of the component is final with regard to responsibility. Alloy muffle, retorts, fans, castings, and other alloy parts are not warranted against warpage, cracking, or weld failure except insofar as the alloy fabricator of the component determines, through its analysis, that such failure was due to faulty material or workmanship. Ceramic parts, including but not limited to, hearth plates, are not warranted against breakage. The warranty is not valid for second-hand or damaged kilns sold by unauthorized sellers. Any modifications to the original kiln by anyone other than the factory or someone specifically authorized in writing by the factory will void the warranty. Any modification is made solely at the customer's risk. L&L takes no responsibility for hazardous conditions created by unauthorized modifications. Repair and Replacement If any part needs repair or replacement during the warranty period, L&L, at its sole discretion, L&L will repair or replace the necessary items at no cost to the purchaser, not including disassembly or reassembly costs and/or any re-packaging or handling. L&L will prepay return shipping cost without charge in the Continental United States. Shipping outside the Continental United States is at cost. To take advantage of this Standard Commercial Limited Warranty, the Buyer may be asked to return defective parts to L&L for inspection. Conditions Voiding Warranty Using elements and/or parts other than genuine L&L Kiln parts. Kiln warranty may be voided by firing materials that introduce harmful atmospheres into the kiln. Atmospheres containing carbon, reducing atmospheres (caused, for example, by introducing carbonaceous gasses or solids like graphite or paper into the kiln), binders from lusters and decals, wax burn-out effluents, fluorenes, halogens, acids, sulfur, metal oxides, and salts are some of the corrosive and harmful atmospheres that will damage a kiln. Most ceramic processes will release some of these harmful constituents into the kiln and venting will prevent most of the problems that those processes would cause. Also, depending on the concentration of the toxic gases, kiln ventilation (such as our Vent-Sure) may limit the damage to the kiln. The customer is responsible for ensuring the materials and processes are not harmful. Damage due to neglect, inadequate room or kiln ventilation, mechanical abuse, improper storage, insufficient maintenance, improper use or freight damage. Damage to the elements or element holders due to failure to keep the kiln clean properly. Damage to the kiln caused by firing in ambient conditions that are too hot for the control or other components in the kiln. The DynaTrol (or Genesis) is rated up to 125°F (52°C). That means the room temperature should be less than 100°F (38°C) (because the control will be slightly hotter than room air due to heat transfer from the kiln). Note that direct sunlight on the control face may raise the board's temperature beyond what you would expect from the ambient temperature or the kiln heat. Exclusions Firebrick is naturally fragile and will chip, crack, and create dust. L&L designs its kilns to minimize these effects but cannot warrant against cracking, breakage, spalling, or dusting. There is specifically no warranty for cracked arches, tops, lids, or bottoms. Corrosion of the case is specifically not warranted. Exposure to certain ambient conditions, including but not limited to humidity, acid, rain, snow, dust, and salt air will cause corrosion. This Standard Commercial Limited Warranty does not cover losses or damages caused by the malfunction of the control system or thermocouple or by the mismatching of control and thermocouple type (after the initial configuration by L&L). Note that any time a control is installed as a replacement it is the Buyer's responsibility to check the control configuration before operating the kiln. L&L highly recommends the use of an over-temperature safety system. Overfiring of the kiln for any reason, including, but not limited to, faulty controls, thermocouples, or improper wiring, is not covered under this Limited Warranty. Limitations This Limited Warranty does not extend to the Buyer's process of manufacture or to the quality of the products processed in the kiln or through the use of the Kiln. The Kiln is not warranted for any specific uses unless stated explicitly in the L&L quotation and the disclaimers and exceptions contained in the L&L Standard Commercial Limited Warranty and in the L&L Terms & Conditions of Sale apply to this order. L&L is not responsible for downtime costs and equipment failure or malfunction expenses. This Standard Commercial Limited Warranty applies only to the original purchaser of the equipment (i.e., the Buyer). L&L is not responsible for any consequential, secondary, or incidental damages resulting from, or caused by, the malfunctioning of its equipment, regardless of how arising, or for any other reason. L&L's liability is expressly limited by the terms of L&L's Standard Terms & Conditions of Sale and by this Standard Commercial Limited Warranty. All technical advice, recommendations, and services are rendered by L&L free of charge and are based on data believed to be reliable or which was furnished by the Buyer. Such information is intended for use by skilled and knowledgeable persons at their own risk. L&L assumes no responsibility to the Buyer for any events resulting from or damages incurred from using such information on the part of Buyer or L&L. Any advice given is not to be taken as a license to operate under, nor to suggest infringement or disregard of any existing patent or instructions from another manufacturer. Buyer agrees that L&L's total and cumulative liability for any and all damages or remedies arising hereunder or in any way related to this order shall be limited to direct and verified damages in an amount not exceeding the purchase price paid by Buyer to L&L, excluding holdbacks. On-site labor is not part of this warranty and is not covered by L&L. L&L's warranty is strictly limited to repairing or replacing defective items. Kilns may not be returned. Compliance L&L is not responsible for compliance with applicable Federal, State, Province, or Local governmental safety, environmental, licensing, permitting, or performance statutes, ordinances, rules or regulations unless noted explicitly in L&L's Quotation, and then only concerning such laws, ordinances, rules, or regulations which are published and in force as of the date of the Quotation. Implementation of all such statutes, ordinances, rules, or regulations at the Buyer's location where the kiln is installed is, and will remain, the Buyer's responsibility. Safety Buyer acknowledges that process and manufacturing systems improperly installed, maintained, or operated can pose serious and dangerous threats to worker safety, environmental integrity, and product/process quality. The kiln may be provided with various safety, performance, and operating limits, designs, and devices which, if disconnected, altered, tampered with, or changed by Buyer, Buyer's employees, Buyer's agents, or others acting on Buyer's behalf or with Buyer's knowledge, will become Buyer's sole risk and responsibility and such actions will absolve L&L of any obligations and liabilities concerning the function of such limits, designs, and devices, and further, Buyer shall indemnify and hold L&L harmless for any damages incurred by L&L due to such above actions and/or non-action(s) on Buyer's part.
