Installation must conform to local codes. Contact your local building or fire oicials about codes,
restrictions, and installation inspection in your area. In the absence of local codes, installation
must conform to the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Natural Gas and Propane
Installation Code, CSA B149.1, or Propane Storage and Handling Code, B149.2, as applicable. It is
recommended that this oven be installed, maintained and serviced by authorized professionals.
Always disconnect the power supply to the oven before servicing or cleaning.
IMPORTANT: Always use safety equipment provided with your oven such as gas regulator and gas leak
detector. Do not change gas orifices without consulting manufacturing representatives prior to making
change. Incorrect orifice or gas pressure can result in carbon monoxide exceeding safety levels.
IMPORTANT: Do not change fuel types between natural gas and propane without consulting
manufacturer, manufacturer’s representative or local service representative. Natural gas and
propane require dierent orifices and failure to use correct fittings can present risk of fire or carbon
monoxide poisoning.
WARNING: Always shut o natural gas or propane source and purge line when not in use or before
performing maintenance on gas module. When operating oven as wood only, be sure to turn o
natural gas or propane supply line and set to o position on control panel.
IMPORTANT: When using gas burner aer sitting, test for leaks before firing oven. If pilot light goes
out, use gas leak detector to check for gas buildup before reigniting.
DANGER — IF YOU SMELL GAS:
1. Shut o gas to the oven.
2. Extinguish any open flame.
3. Open door.
4. If odor continues, keep away from the oven and immediately call your gas supplier
or your fire department.
In a prominent location, please post a statement outlining this procedure (or an alternate
procedure to follow in the event that you smell gas, available from your local gas supplier.)
WARNING — FOR YOUR SAFETY:
1. Do not store or use gasoline or other flammable vapors or liquids in the vicinity of
this or any other appliance.
2. An LP cylinder not connected for use shall not be stored in the vicinity of this or
any other appliance.
3. Always keep the area under and around this appliance free and clear of any and all
combustible materials.
WARNING. Improper installation, adjustment, alteration, service, or maintenance can result in
property damage, injury, or death. Please read this entire manual and the installation, operating,
and maintenance instructions thoroughly before installing or servicing this equipment.

WARNING
READ ALL INSTRUCTIONS BEFORE INSTALLING AND USING THE APPLIANCE. FAILURE TO FOLLOW
INSTRUCTIONS MAY RESULT IN PROPERTY DAMAGE, BODILY INJURY, OR EVEN DEATH.
When this oven is not properly installed, a fire may result. To reduce the risk of fire, follow the installation
instructions. It is essential to use only building and insulation materials designed for the purpose.
Use proper safety equipment when installing this oven, including gloves and professional breathing masks.
Contact your local building or fire oicials for clarification on any restrictions on installation of this oven in
your area, or need for inspection of the oven installation.
HOT WHILE IN OPERATION. KEEP CHILDREN, CLOTHING AND FURNITURE AWAY. CONTACT MAY CAUSE SKIN BURNS.
DO NOT BURN GARBAGE OR FLAMMABLE FLUIDS.
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.
Keep children and pets away from hot oven.
Use firewood for burning only. DO NOT use charcoal, pressure treated lumber, chipped wood products, sappy
wood such as pine, laminated wood or any material other than dry medium or hard firewood.
DO NOT USE liquid fuel (firelighter fluid, gasoline, lantern oil, kerosene or similar liquids) to start or maintain a
fire.
BEWARE of very high temperatures in the oven and use long oven gloves and mitts to handle pots and tools.
DO NOT put unprotected hands or arms inside oven while it is lit.
Dispose of ashes using a metal shovel and place in a metal bin with a tightly fitting lid. The container should
be stored on a non-combustible surface, away from all combustible materials. Ensure ashes are completely
cold before disposing of them appropriately.
BEWARE of flying sparks from mouth of oven. Ensure that no combustible materials are within range of oven
at any time.
DO NOT close the oven door fully while a fire is in the oven. Closing the door fully will cut o oxygen to the fire,
causing the fire to erupt suddenly when the door is removed. Always keep door tilted to allow air to circulate
in the oven.
DO NOT use water to dampen or extinguish fire in the oven.
DO NOT pack required air spaces with insulation or other materials.
When the curing of the refractories is not done as part of the manufacturing process, the manufacturer’s
recommended curing process shall be specified. Follow the instructions for curing the oven. Failure to follow
the curing schedule can cause damage to the oven, and void the oven warranty.

Oven Clearances
It is essential to maintain clearance space between the oven
components and any combustible material, such as walls
and ceilings. Failure to maintain these clearances can result
in fire.
Combustible Wall Clearance
The oven must have a minimum 1" (25 mm) clearance to
combustibles from all sides, and 14" (35 cm) clearance to
combustibles from the top.
If building materials will contact the oven, they must be
completely noncombustible. Please note that standard
drywall (or sheet rock) is considered a combustible.
The area directly above the doorway and 6" (15 cm) to
each side of the doorway must be covered with non-
combustible material.
Non-combustible construction may contact the oven and
must then maintain 1" (25 mm) clearance to combustibles.
If the space between the legs of the stand is used for wood
storage, it is recommended that it be a covered container
or box to prevent the possibility of sparks or embers from
making contact with the stored wood. An 8-1/2" (eight
and one-half inch) (21 cm) air space clearance is required
between the bottom of the oven and any wood storage
container.
Floor Hearth Extension
The minimum floor hearth extension areas from the oven
door opening to combustible floors are as follows:
☐ 30" (76 cm) to each side of the door opening
☐ 36" (91 cm) in front of the door opening

The stand dimensions for your specific oven installation
are based on the following formula:
Width = Oven exterior width + insulation thickness +
enclosure wall thickness.
Depth = Oven exterior depth + rear insulation thickness +
rear enclosure wall thickness + landing depth
The sample dimensions above are based on 2" (5 cm)
upper walls and a 6" (15 cm) oven landing. Adjust your
dimensions according to your specific installation.

1. Foundation
Overview
Your oven stand and oven chamber are installed on a
concrete pad. We recommend a minimum thickness
of 5 1/2 " (14 cm) for the foundation slab, however
your location, soil conditions and local building
ordinances will dictate the thickness required.
The slab dimensions listed below are 8" (20 cm) wider
than the dimensions of your concrete block stand,
providing you with 2" (5 cm) for finish material, and a
2" (5 cm) reveal on either side of the stand. The slab
is also 10"(25 cm) deep, allowing for 4"(10 cm) in the
back (2" (5 cm) finish and reveal), and 6" (15 cm) in
front (the additional space makes a nice edge for your
wood storage). The foundation slab will also be used
to support forms that you will use during the hearth
slab construction The finished top of the slab should
be 2"-3" (5-8 cm) above ground level.
Instructions
First, excavate your foundation. The slab frame for a
5 1/2"(14 cm) foundation is best composed of
2" x 6" (5 x 15 cm) lumber set so the top of the form
is 2-3" (5-8 cm) above ground level. The longer form
boards should sit inside the shorter boards, and
the completed form can be held in place by driving
wooden stakes into the ground around the perimeter.
Before securing everything permanently, check
to make sure the form is located and faces exactly
where you want it, and is level and square.
Lay a 3" (9 cm) base of pea gravel (or crushed rock),
compact the rock, and cover it with a layer of 6 ml
plastic sheeting to stop the slab from wicking water.
Place a sheet of wire mesh inside the foundation
frame, and install a two-piece grid using 1/2" (1 cm)
rebar (#4) set 4"(10 cm) and 8" (20 cm) inside the
foundation frame. Tie the rebar together with tie
wire, then set the wire mesh and rebar half way up
the pad (2 3/4” or 7 cm) , using either rebar stand-os
or fragments of brick.
1.1. Framed, lined, with wire mesh and rebar.
Mix and pour the concrete, and then level it. Use a
2"x 4" (5 x 10 cm) to screed and level the concrete,
then finish to a smoothness that works for you as the
bottom of your wood storage area. Allow the slab
to cure for a day or two. Keeping it damp will help it
cure better and become stronger.
1.2. The nished foundation ready to cure.
Other Considerations
Depending on where you live, you may have to
excavate 18" (45 cm) or more, of topsoil to reach a
stable substrate such as hard clay. If you do excavate
to a depth greater than the foundation form height,
you will need to add a material, such as thoroughly
compacted pea gravel or crushed rock, which will
allow for the drainage of water from under the
concrete slab. Placing a layer of plastic sheeting over
the material will help prevent it from wicking water

from the slab too quickly, making it brittle and prone
to cracking.
You may also want to install your oven as part of a
larger outdoor kitchen project. Use the dimensions
for the oven in conjunction with your other kitchen
elements, such as counters, a grill, storage, a sink,
and refrigeration. You might find it easier to form your
entire kitchen at one time.
Hints and Tips
Use a tiller to break up the ground before you
excavate. You can rent one from Home Depot. If your
ground is hard and/or dry, water it with a sprinkler for
a couple of days before you start. Your site should be
so, but not muddy.
Compare both diagonal measurements of your
foundation frame to ensure that your foundation will
be square. Double check that your foundation really
faces the exact direction you want your oven to face.
Once the diagonals are of equal length, you may
want to temporarily attach 2"x 4" (5 x 10 cm) lumber
horizontally to form triangles at the corners and hold
your form square during the pour.
The weight of concrete in the foundation can be
heavy (40 80 lb. bags or more), and mixing it by hand
in a wheelbarrow might use up energy and time that
will serve you better later in the project. Rent a mixer
from Home Depot, and ask a friend (or pay a local
teenager) to help you mix and pour the slab.
There are also mix-on-your-site trucks that come and
just make as much concrete as you need on site, so you
might want to price this option if available in your area.
Check with your local equipment rental company for
a 1-yard mixer that you can tow behind a standard
pickup truck.
If your building site is far from your street or curb,
you can hire a concrete pump to shoot the concrete
where you want it. The pump rental is typically a
dierent company from the concrete delivery truck.
2. The Oven Stand
Overview
The oven stand is typically constructed using
standard 8"x 8"x 16" (20 x 20 x 40 cm) concrete
masonry units (CMU), though it can also be made
from brick, metal, or formed concrete.
Instructions
Build a block stand comprised of four courses using
standard 8"x 8"x 16" (20 x 20 x 40 cm) and 8"x 8"x
8" (20 x 20 x 20 cm) concrete blocks. The first three
courses of the block stand form a three-sided U,
leaving an opening in the oven front that provides
access for wood storage. The fourth course of blocks
spans the opening at the front of the U, by resting on
two pieces of 2"x 2"x 3/8" (50 x 50 x 9.5 mm) angle iron.
Using a chalk line, mark the layout of your block
stand directly on the foundation slab. Make sure that
it faces exactly where you want your oven opening
to face. Then, lay your first course of blocks directly
on your slab. Use pre-mixed mortar where necessary
to ensure that the first course of blocks is level, front
and back, side to side, and on the diagonals.
Take your time with getting the first course set
correctly, because it will be increasingly diicult to
correct problems later.
2.1. Carefully lay out the rst course of blocks.

In the following courses, stagger your blocks using
either 8"x 8"x 8" (20 x 20 x 20 cm) blocks, or cut
blocks, to ensure that the joints are oset. Lay the
next two courses, for a total of three.
Aer you have laid your first three courses, set your
two pieces of 2"x 2" (5 x 5 cm) angle iron across the
opening between the two legs of the U shape. Note
that the back piece of angle iron must be cut to allow
clearance for the rest of the top course of blocks.
2.2. Cut the back angle iron to leave room for blocks.
Grind, or cut, 3/8" (9.5 mm) from the edges of each
block that rests on the angle iron, so that they lie
flush with the rest of the fourth course. Finish laying
the rest of the fourth course of blocks.
2.3. The nished stand.
Aer you have completely assembled the block stand,
check that the walls are square, level and plumb.
Drop a section of 1/2" (12.7 mm) rebar in every other
core, and fill those cores with concrete.
Gas option: a minimum of 19 3/4" w x 19 3/4" h (50.1
cm w x 50.1 cm h) opening is required for air flow to
burner assembly.
Variations
Variations include round stands, corner ovens, oven
with an attached outdoor kitchen, pre-cast lintels,
and metal stands.
2.4. Custom metal stand with stud frame.
Tips and Hints
When selecting the direction your oven will face, consider
making sure that your opening does not face possible winds,
which might disrupt your cooking and fire management.
We also recommend dry stacking your blocks, then
filling every other core (or the corners) with concrete.
It’s a lot faster, and sturdier as well. Block the cores that
you have not filled with your empty concrete bag to stop
your hearth concrete from spilling into the holes.
