1. Adequate
space - at least 12 inches
of space between the kiln and
the wall. (However, for operator
comfort, allow room to walk
around the kiln if maintenance
is required. Stackable kilns
require tightening of the kiln
rings while firing for proper
alignment.)
2. All
flammable materials such as
curtains, plastics, etc. in
the area of the kiln should
be removed. Determine room
size required from the outer
dimensions of the kiln you
wish to purchase. For commercial
kilns, check door width, and
if the door is insufficient
to allow kiln entry, contact
Olympic Kilns to check if modifications
can be made to kiln before
it is ordered and built.
3. Proper
ventilation - Heat can accumulate
in restricted areas above both
gas and electric kilns if a
hood is not used. If the kiln
is gas and located in a confined
area it is essential that an
exhaust hood be place above
the kiln and vented to the
outside. This ensures removal
of heat and exhaust gases,
including carbon monoxide.
Even if the kiln is outside
be sure that the hot exhaust
gases do not cause damage.
Check all local requirements
or codes before installation.
1. Position
the kiln with the observation
holes clearly visible and with
the switches, kiln sitter or
electronic controller within
easy reach.
2. For
kilns equipped with a power
cord, place the kiln to the
left of the proper electrical
outlet so that the kiln can
be plugged in without touching
the metal jacket.
3. Because
all kilns generate heat the
stand or frame should be placed
on a cement floor. Tiles or
linoleum could be damaged without
this precaution.
4. If
the kiln is to be placed outside,
ensure that moisture is not
permitted. Use a roof over
the kiln or some type water
resistant tarp when the kiln
is not being fired.
5. Remember
to use sheet metal or non-flammable
material to shim the legs when
leveling the kiln.
To
provide the performance it
was designed to give, your
new kiln must have the proper
outlet and breaker to supply
adequate voltage and amperage.
An incorrect connection may
cause disappointing or even
hazardous results. A qualified
electrician needs to be consulted
to determine whether your wiring
is adequate.
Electric
kilns running on 120 volts
will plug into a standard outlet
but check your breaker to ensure
proper performance. Standard
electric kilns will run on
240 volts, single phase. If
your kiln was ordered 208 volts,
single or three-phase power,
it will be noted on the nameplate
on the kiln. Commercial electric
kilns may be wired for 240,
208, 380, or 480 volts; single
or three phase. Most commercial
kilns require direct wiring
and a receptacle outlet is
not required.
Any
kiln ordered three-phase will
be direct wired (there is not
a power cord attached to the
kiln).
If
you purchase an Olympic 120-volt,
Front Loader, Electric Raku
or Solid Jacket electric kiln,
your kiln is ready to fire
upon arrival. After the kiln
is unpacked or removed from
the pallet, place kiln directly
on stand; or in the case of
a kiln with attached frame,
place the kiln where it is
to be located, plug-in and
fire away.
Kilns
built in rings and those with
counter weight lid systems
must be disassembled from the
shipping pallet then reassembled
on the stand. The proper method
is to remove the top ring and
place the bottom of the top
ring flat on the floor. Repeat
for each section until you
reach the bottom of the kiln.
Place the bottom on the kiln
stand with the hose clamps
to the back. At this time the
stand can be leveled. If shims
are required to make the bottom
level, or prevent rocking of
the bottom on the stand, use
only sheet metal under the
legs of the stand. Now reassemble
the kiln with the observation
holes to the front and electrical
boxes aligned. Grasp the rings
by the outside surface and
not the firebrick to avoid
damaging the kiln. If the lid
brace of the kiln was disconnected
for shipping it should be reconnected.
Olympic
Commercial Electric kilns are
assembled and ready to fire
upon receipt.

Olympic gas kilns burners are
factory set for use on either
propane or natural gas determined
by the customer's order.
If propane is used, your
tank must have a low-pressure
regulator like those on a
camper or trailer. If an
adjustable regulator is used
approximately ½ pound
of pressure is necessary.
The larger the tank the better;
however, a five (5) gallon
tank is the minimum size
for the 1827G or 18 Raku
and a 15 gallon tank is the
minimum size for the 2327G/23
Raku and 2827G/28 Raku kilns.
Due to gas flow, the propane
tank may have a tendency
to freeze solid. If ice is
observed forming on the outside
of the tank, water can be
run over it to help keep
it melted. The tank can also
be lowered into a large bucket
of warm water.
A larger burner orifice in
necessary when used on natural
gas pressure, six (6) to
eight (8) inches of water
column is required. If your
kiln was ordered for use
on household natural gas,
it is equipped this way.
Olympic Torchbearer kilns are
built in rings and may be
detached and reattached when
moving from one location
to another. When handling
your new kiln rings, always
be sure to grasp the rings
by the outer surface only.
Do not grasp the bricks as
they are made of a porous
material and may chip in
your hand. Raku kilns are
shipped fully assembled.
After
making certain the stand
is level, adjust the burner
manifold so the pipe section
on top of each air mixer is
approximately ½ inch
below the bottom of the kiln.
The kiln bottom must be positioned
on the stand so each burner
is directly beneath one of
the holes.
 |
It
is recommended that the
burners be positioned with
the gas valve on the right
side when you are facing
the kiln, however, if it
is more convenient to place
the manifold in another
position be sure to align
the burners with the holes
in the kiln bottom.

Proper ventilation is required when firing a gas kiln. Gas kilns fired outside may not require a vent. When purchasing vents it is often best to choose a local HVAC or sheet metal manufacturer, or Olympic Kilns can manufacturer one for you. Vent dimensions need to be round or square in a cone shape and the bottom of the vent needs to be larger than the outside diameter of the kiln. Diameter at the top of the vent needs to be 10" discharging into an exhaust pipe required by building conditions or local codes.

- Because
all kilns generate heat,
the burner system/stand should

Vinyl tiles or linoleum could
be damaged without this precaution.
It is important that the
kiln be fired only on the
metal stand or frame provided
with the burner system. The
eleven-inch height of the
frame is necessary for proper
burner positioning and adequate
cooling beneath the kiln.
Remember to use sheet metal
or non-flammable material
to shim the legs when leveling
the kiln.

Olympic gas kilns burners are
factory set for use on either
propane, or natural gas from
a street main. If propane
is used, your tank must have
a low-pressure regulator
like those on a camper or
trailer. If an adjustable
regulator is used approximately ¾ to
1 ½ pounds of pressure
is necessary. The table below
is the minimum size tank
for a cone 10 firing for
each DownDraft model. You
need to purchase a larger
tank than the cone 10 firing
requirement so that you are
not having to refill the
tank after each firing.

A larger burner orifice in
necessary when used on household
gas pressure of six (6) to
eight (8) inches of water column.
If your kiln was ordered for
use on household natural gas,
it is equipped this way.
Olympic DownDraft kilns are
shipped ready to fire. There
is no assembly of putting
the kiln together, unless
you have requested a custom
kiln. If you have requested
a custom order, example a
DownDraft kiln with outside
dimensions that cannot normally
go through a 34 ½" door.
If the door has to be taken
off, or some other irregular
situation is needed, contact
Olympic Kilns before dismantling
the kiln to maintain your
warranty and to insure that
no damage occurs to the kiln.
Proper ventilation is required
when firing your gas kiln.
Gas kilns fired outside may
