When it ships & how it's delivered · freight to your door

Paragon builds most kilns to order once your order is placed. We email your confirmed ship date and tracking.

  • The freight carrier calls you to book a delivery window.
  • Delivery is curbside with a liftgate. Have a helper or hand truck to move it inside.
  • Check the crate before you sign. Note any damage on the receipt and send us photos.

Authorized Paragon dealer · full factory warranty

Brand new and shipped direct from Paragon, so it carries Paragon's full factory warranty. If something goes wrong, call us and we handle the claim with the factory for you.

Warranty terms are in the Warranty and support section below.

Returns: request within 15 days, unused

Because kilns are heavy and often built to order, returns are limited, so we'd rather help you pick the right one up front:

  • Ask within 15 days of purchase or 2 days after delivery, whichever comes first. We issue a return authorization (RA).
  • It must be new, unused (beyond the factory test fire) and in its original packaging.
  • A restocking fee of at least 25% applies, up to 50% on custom, 3-phase or made-to-order units. Return freight is on the buyer unless we made an error.
  • Damaged in transit? Note it on the delivery receipt, send us photos and we'll help with the freight claim.

Will it work in my space? Power check

Most 240V kilns need their own circuit and the matching outlet, installed by an electrician. Homes are usually 240V; schools and commercial buildings are often 208V, so pick the voltage that matches your panel.

Send us a photo of your breaker panel or outlet and we'll confirm before your kiln is built: 470-264-3563 (call or text).

The KM45's recessed heating elements sit in machined grooves for even heat distribution across the full 45-inch depth, backed by a solid-state relay with a dedicated backup safety relay. It ships in a rigid steel case with a built-in stand and runs on 240V single-phase power with Paragon's SENTINEL Touch Xpress controller.

What’s included
The oven, assembled and wiredParagon builds and wires it at the factory. The door style you chose is already fitted: a spring-assisted drop door or a side-swing door, both standard at the same price.
Digital controller, factory-installedParagon fits and wires the controller before the kiln leaves the factory. Paragon has been renaming and replacing its controller line and dealer listings are out of date at different dates, so we do not print a model name here. We confirm the exact controller with Paragon when you order.
Type-K thermocouple, installedFitted at the factory and wired to the controller. Type-K is standard across the current Paragon range.
Door safety switchWired in at the factory. It cuts power to the elements the moment you open the door, so you are not reaching into a live chamber.
Cord and plugParagon ships this kiln with a cord and plug. The receptacle type changes with the voltage option you order, so we confirm the exact plug — or whether your configuration is wired direct instead — with Paragon before the order goes in.
Printed manualsA printed instruction manual for the kiln and a separate guide for the controller. Warranty registration is done online at Paragon, and we do not promise a printed warranty card in the crate because we could not confirm one is packed.
Paragon limited warranty — one yearOne year from purchase on this model, per Paragon's published warranty schedule. Paragon does not warrant the Type-K thermocouple, so treat that as a wear part. Keep your proof of purchase.
Not includedNo shelves, posts or kiln furniture ship with a knife oven. The Knifemaker's Heat Treating Kit — four knife holders, eight firebrick supports, a heat treating fork and hot gloves — is a separate purchase, and so are the upgraded touchscreen controller and the gas-inlet option.

Common questions
What can I heat treat in a chamber this long?
The 45-inch chamber is built for full-length swords, machetes, and other long blades that won't fit in shorter knife ovens, as well as batch loads of several standard-length knives at once. At 2350°F max, it covers hardening and tempering for high-carbon steels (1095, 1084, 1075) and common tool steels (O1, A2, D2).
Why does the KM45 use a solid-state relay instead of mercury relays?
The KM45 ships standard with a solid-state relay (SSR) and aluminum heat sink, plus a dedicated backup safety relay. SSRs switch faster and more quietly than mechanical relays and have no moving parts to wear out, which matters over the long, even heating cycles a 45-inch chamber requires.
Does the KM45 come with a stand?
Yes — unlike some of Paragon's shorter knife ovens, the KM45 ships in a rigid steel case with a built-in stand, so there's no separate stand to purchase or assemble. It's ready to plug in and stand on its own in your shop.
How does the KM45 compare to the KM36 and KM24?
All three run on 240V single-phase power and reach the same 2350°F maximum, differing mainly in chamber depth — 24", 36", and 45" respectively. The KM45 is the choice for bladesmiths who regularly work with swords or other long-format blades and need the extra length; for standard knife lengths, the shorter models are more space-efficient.
Can I purchase this oven through any dealer, and how does the warranty work?
Paragon warranties are only valid when purchased through authorized dealers like Peach State Pottery. You must register your oven within 30 days of delivery to activate the one-year limited warranty. As an authorized Paragon dealer, we provide full warranty support, technical assistance, and access to genuine replacement parts.
