eFL Series Assembly Instructions
Rev: 3/1/2025
BEFORE YOU GET YOUR KILN
- Read these instructions and decide how you will handle the kiln when you get it - don’t wait until it arrives.
- Decide how you are going to unload the kiln. eFL Kilns are not like typical top loading sectional kilns. They are top-heavy and require special handling to unload and move them. In particular the largest model requires special handling because of its weight.
- Note that weights and center of masses are indicated on the General Dimension Drawings which are available on each kiln model page.
- If you are not comfortable moving and installing the kiln yourself - especially if you have difficult installation conditions - we can recommend hiring a professional moving company or rigger to unload the kiln from its pallet and put in place.
- Remember, because of the nature of the product, there is some unavoidable risk and you must take proper safety precautions at all times.

CAUTIONS & DELIVERY ISSUES
How to unload & move your eFL kiln
- The high center of mass makes the eFL kilns a potential tipping hazard. The kilns can weigh over 500 lbs. and are top heavy. If the kiln leans over far enough to exceed the tipping point it will fall over and the weight of the falling kiln could cause severe injury or death.
- Exercise extreme caution at all times when moving and if you do not feel qualified to do the job then hire a professional.
- If you have the caster option never move the kiln from above the base (like by pulling on the door handle.)
- eFL Kilns, unlike sectional top-loading kilns, cannot be easily disassembled for easy moving.
- They cannot be removed from a truck without the aid of a lift gate or fork lift.
- They cannot easily be lifted over curbs, transported on non-paved roads or walkways, tilted (because of being top heavy), or moved up inclines without a forklift or other secure method.
- They cannot be moved up or down stairs.
- Terrain and grade must be essentially smooth, hard and flat. (Note: it may be possible to cover gravel or grass with plywood to move the kilns).
- No second story installation unless you have an appropriate elevator (because the kiln body cannot be disassembled and moved up stairs).
- 30” minimum door opening
Trucking Company Rules
- No dirt roads
- No dead ends
- Must have ability for truck to turn around
- No woods/narrow drives
- Gravel drive depends on weather (no rain or snow in forecast)
- No inside delivery
- Lift gate unavailable for certain addresses
Where can the kiln be delivered?
- Any addresses with loading docks and/or forklifts.
- Shipping to typical shipping terminals is not acceptable because ownership cannot be transferred to the buyer before opening and inspecting the kiln. If any damage were to happen between the terminal and the final destination no claim could be filed.
- L&L cannot be held responsible for any damage to the kiln once it is moved from its initial delivery location.
- Any place where you can promptly inspect for shipping damage (MUST BE WITHIN 2 DAYS) and then subsequently move safely to your location. L&L cannot take responsibility for any damage after the initial inspection.
- Homes where the above trucking company rules are met.
- Difficult addresses might require you to have the kiln shipped to a professional mover and then moved into place by the mover.
WHEN YOU FIRST RECEIVE YOUR KILN: INSPECT FOR DAMAGE!
There are three main causes for shipping damage:
- Dropping the kiln when loading and unloading during a terminal transfer during shipping
- Tipping over (this will be very obvious)
- Excessive Vibration. This will be hard or impossible to detect until you have opened up the package.
Who is responsible for inspecting your kiln?
- L&L takes responsibility for filing damage claims as long as customers follow our guidelines.
- FREIGHT COMPANIES ALLOW 2 DAYS TO REPORT SHIPPING DAMAGE.
- WE CANNOT HELP YOU WITH A DAMAGE CLAIM AFTER 2 DAYS.
- If box is dented, crushed, un-banded or off the skid, note it on Delivery Receipt.
- Inspect the Kiln Shock Watch Label on the outside of the crate. If it is red then note “Possible Concealed Damage” on the Bill of Lading.
- Check number of cartons against Delivery Receipt. Inspect contents while driver is present.
- If this is not possible, take photos and mark Delivery Receipt “SUBJECT TO INSPECTION.”
- If obvious severe damage is visible, take photos and refuse shipment.
- After you have received the kiln the first thing is to open the package enough to inspect the door brick (located in the back of the box) and the front of the kiln face in the front. You do not have to unpack the kiln beyond that point if you intend to store it before installing it.
- IF YOU FIND DAMAGE: Take as many photographs of everything as soon as you can and email them to service@hotkilns.com. The time stamp on these photograph/emails is critical when filing a damage claim!
- If you can, write a description of the breakage or damage or shortage on all copies of the freight bill before you sign it. Make your notations as specific as possible to protect if concealed damage is subsequently discovered. (In some cases, the shipper may not allow you to do that).
- See hotkilns.com/shipping for full policy.
- Damages must be reported immediately. If there is any problem at all, call L&L (856-294-0077) if during our business hours (preferably before the driver leaves).TAKE PICTURES, AND NOTE ON THE BILL OF LADING ANY DAMAGE. If you don’t, there is no recourse against the carrier who is responsible for the condition of the kiln when it is delivered. Once you accept the kiln, it is not returnable.
Placement and Location
- GENERAL DIMENSION DRAWINGS: You can find the General Dimension Drawing of all kilns on the webpage of each kiln model. These have ventilation requirements and clearance requirements
- L&L strongly recommends an 18" clearance to all walls. The Uniform Mechanical Code 2000 Edition states that "the sides and tops of kilns shall be located a minimum of eighteen (18) inches (457 mm) from any noncombustible wall surface and three (3) feet (914 mm) from any combustible wall surface."
- The National Fire Protection Agency states that temperatures at combustible ceilings and floors be kept below 160 Deg F (71 Deg C) near industrial furnaces (which are like kilns).
- Note that, when L&L tested kilns for UL, temperatures were measured 12" from the walls of the kiln and found to be safe from a flammability standpoint. However, locating a kiln just 12" from a wall may violate the Uniform Mechanical Code and possibly local fire codes, so do this at your own risk.
- Check with local building codes for recommended non-combustible wall materials for walls that are adjacent to the kiln. Cement board, cinder blocks, and masonry tile are possible choices.
- Make certain floor is not flammable. The Uniform Mechanical Code 2000 Edition states that "kilns shall be installed on noncombustible flooring consisting of at least two (2) inches (51 mm) of solid masonry or concrete extending at least twelve (12) inches (305 mm) beyond the base or supporting members of the kiln."
- Recommended floor surfaces are cement, ceramic tile, stone, slate, cinder blocks or brick. Do not install on a wood floor or on carpet. Vinyl flooring may be combustible. Protect linoleum flooring from discoloration with a noncombustible covering.
- BE VERY CAREFUL ABOUT IMPLEMENTING THESE SUGGESTIONS. Remember that the kiln is putting out heat over a long period of time and that this could very well start a fire under certain conditions. Also, if an overfiring occurs, materials like glass and glazes can be super-heated and electrically conductive, and they can melt right through the kiln floor. If there is a combustible floor, this could cause a fire. Also keep in mind the continued heat of the kiln can dry out combustible surfaces over time and reduce their flash point.
- The NFPA 86 (Section 2-1.5 concerning Floors and Clearances) that might be construed as applicable to kilns requires that temperatures at combustible ceilings and floors be kept below 160°F (71°C). In general, the NFPA recommends installing furnaces on noncombustible surfaces and has specific requirements if this is not possible.
- Make sure you have 24” in front of the panel and 18” in the back to be able to perform maintenance functions on the kiln.

Assembly
TOOLS TO HAVE ON HAND
The following list assumes you will be doing all of this work yourself with a team of helpers.
- Two wrenches with 1/2” opening
- One nut driver with a 5/16” opening (for tightening bands) (See video)
- 9/16” socket wrench
- Crescent wrench or box wrenches
- Phillips head screw driver (preferably powered)
- Safety Glasses and gloves
- Knife or scissors
- Standard Pallet Jack
For eFL2626 and eFL2635 kilns you will need an Engine Hoist or other means of lifting the door onto the Door Mounting Brackets. (Watch the video). This can be rented from the same types of places as a pallet jack. You can also rent a pallet jack from them and/or power tools. See this link or search for Sunbelt Engine Hoist: sunbeltrentals.com/equipment/detail/1134/0730011/engine-hoist/
Note: These engine hoists can be disassembled for moving and for moving through a door. There is a video on our unpack-efl page.

WEIGHTS
Approximate weight of kiln bodies without door, vent, hearths or any packing material:
- eFL1616: 325 lbs (147 KG)
- eFL1626: 410 lbs (186 KG)
- eFL2026: 425 lbs (193 KG)
- eFL2626: 490 lbs (222 KG)
- eFL2635: 575 lbs (261 KG)
Approximate weights of doors:
- eFL1616: 80 lbs (36 KG)
- eFL1626: 100 lbs (45 KG)
- eFL2026: 120 lbs (54 KG)
- eFL2626: 135 lbs (61 KG)
- eFL2635: 160 lbs (73 KG)
STARTING THE PROCESS
- Watch the video above.
- Remove all external packing materials but NOT the box inside the kiln and NOT the straps around the kiln case.
- Inspect for shipping damage.
- With the kiln still on the pallet, move the kiln onto a level area as close to where you are going to install the kiln. The floor must be as level as possible when you remove the pallet.
- Remove the door from the pallet by hand and set aside.
- Follow the video instructions.
Be mindful of the tipping point of the kiln at all times. You can see the center of mass on the General Dimension drawings. When the door is removed the center of mass is approximately in the center of the kiln about 3 to 12” above the hearth level. The tipping point is approximately 20 Deg. DO NOT EXCEED A GRADE OF MORE THAN 10 DEG (when the door is off). It is much worse when the door is on.
FORKLIFT METHOD
Almost any forklift will do (although smaller is better). Adjust forks to fit between the legs and lift kiln from under the kiln base (not from under the shelves) to keep the center of gravity as low to the forks as possible.
- You can lift it from the front, back or sides.
- Move the kiln into its final position and continue with the final assembly.
- You can use the forklift as a hoist to lift the door with the nylon rope or straps when you are installing the door (if you want to).
MOVING THE KILN THROUGH A 30” DOOR
- Do this BEFORE you reinstall the door of the kiln or the vent system.
- All models are approximately 29-1/2” from the face of the brick front to the back plate of the kiln.
- Move the kiln using a pallet jack or the Forklift until you get it near the door that you need to go through.
- By hand with at least two people turn the kiln so it will go through the door sideways.
- Push it through the door.
- CAUTION: Push the kiln as low as you can and NEVER above the base of the kiln (not on the brick section). This will be below the center of gravity and will make it harder (but not impossible) to tip over. Push SLOWLY. BE VERY AWARE OF TIPPING HAZARDS AT ALL TIMES.
- After this you can resume moving the kiln with whatever method you are using.
INSTALLING DOOR
This is a two person job. For the larger kilns (eFL2626 and eFL2635) use an engine hoist, forklift, or other appropriate means to lift the door up and in position.
- Attach two Door Supports into position as shown using 3/8” Bolts (provided).
- Insert Hinge Bushings (two) in the holes on the Hinge Channel on the top hole as shown and also on the bottom hinge hole.
- Have the 3/8” Hinge bolts and nuts ready to install.
- Lift Door in place onto the Door Supports.
- Slide door back into position and insert the hinge pins (bolts) and secure with the nut. Be sure to leave the stepped bushing in place.
- When you replace the door be sure to check the adjustment so that the seal is even all around the face of the kiln.
- The door hinge has been adjusted at the factory. One of the main reasons L&L ships the door unmounted from the kiln (aside from preventing shipping damage) is to prevent the hinge from loosing its adjustment. If for any reason the door does not fit tightly against the front of the kiln brick then contact the factory for instructions on how to adjust the door.
IF YOU DO NOT HAVE THE CASTER OPTION
- Level kiln with shims or leveling bolts.
- We recommend using the shipping brackets to bolt the kiln to the floor.
IF YOU HAVE THE CASTER OPTION
Note: The caster option is not available on the eFL2635
- Lift kiln up with pallet jack about 1 inch.
- Follow the video instructions.
- Bolt on Casters System using the 3/8” Bolts, lock washers and nuts provided.
INSTALLING VENT
- Install the Vent Collection Box. This gets attached with included hardware.
- See the Vent Instruction for the rest of the process.
FINISHING UP
- Check door for tightness.
- Check for a level hearth.
- Vacuum out kiln for any dust.
- Make sure all elements are tightly in place.
- Install Door Peephole Plug
- Have kiln wired by a licensed electrician following your wiring diagram.
FIRST FIRING
- Leave small ceramic washers that are in the back corners of the kiln in place - at least for the first firing. This ensures that the elements stay in place until they loose their springiness on the first firing.
- Do your first firing following the First Firing Instructions
