Congratulations, you are ready to go! You may
also add or remove the upper cooking grid at any
time by keying it into the slots at the back of the
grill. Up to 2 additional upper cooking grids can
be purchased to expand your cooking surface to
nearly 1,000 square inches.
Section 2- Important Safety In-
formation
• CAUTION: Your Madera is to be used in an
outdoor location- one that allows for adequate
ventilation and protects from being used in a
wet environment.
• Plug the unit into a GFCI (Ground-Fault Cir-
cuit Interrupt) protected outlet. Remember to
unplug your grill after use. (Wait until cooling
fan has automatically shut off.) Unplug unit
before cleaning or performing service work.
• All surfaces can become hot, including han-
dles. Use caution and grill gloves if needed.
• Supervise children in the area during and
after using the unit as any part of the grill can
become hot.
• Maintain a clearance of at least 12 inches
from the back and sides of your grill. The grill
produces an open ame- do not store any
ammable liquid near the grill.
• Cooking certain foods can cause grease to
accumulate quickly. To prevent grease res;
regularly clean your grill and replace the foil
drip trays. If you do have a grease re, re-
move the food (if you are able to do so safely)
and close the lid until the re is out. Do not
use water to put out a grease re.
• Do not cover the exhaust vents at the top of
your grill.
• Be sure the grill has thoroughly cooled before
cleaning, moving and covering.
• Use only food-grade wood pellets. Do not use
wood chips/chunks, charcoal or lava rocks.
• The Madera grill is for residential purposes.
• Every home should have a type ABC re ex-
tinguisher in good working order
Section 3- Initial Priming and
Seasoning the Grill
Follow these steps one time be-
fore you begin using your grill.
1. Fill the hopper at the rear of the unit with qual-
ity hardwood cooking pellets.
2. Place 1/2 cup of pellets directly into the burn
pot. This fuel allows the grill to light while the
auger is priming for the rst time.

3. Remove and clean your cooking grids with
warm soapy water, then coat with vegetable
or BBQ spray oil and replace on the grill.
4. Plug the grill into a GFCI protected outlet.
5. Power on the grill by pushing the power but-
ton on the control board. Using the TEMP
Arrows set the cook temperature to 480°.
6. Let the grill run for 1 hour then push the power
button again to shut down the grill. The initial
priming and seasoning process is complete
and you are now ready to cook! You will no-
tice that every time you power off your grill
the display will show: - - - . The combus-
tion fan will continue to run for 15 minutes
then the grill will automatically shut down.
This helps to cool the grill and remove
unwanted ash buildup.
Section 4- Cooking With the
Madera Grill
With your Madera Premium Pellet Grill you will
soon be grilling, barbecuing, slow smoking and
even baking. But before we get cooking, here
are a few helpful tips to keep your grill looking
and working as fantastic as your food is going to
taste:
• Only use premium grade BBQ wood pellets.
Do not use home heating pellets. We recom-
mend Bear MountainTM Premium Hardwood
Cooking Pellets available through you dealer
or at maderagrills.com
• Keep your pellets and your grill dry by always
covering your grill.
• You may cover the sides of the drip tray and
Quick Grill Zone cover with aluminum foil to
make cleaning easier.
• Wipe down your grill with a damp cloth before
and after each use.
About Your Digital Controls
Your Madera grill automatically controls the tem-
perature, smoke, and convection with the push of
a button. There are two basic user modes for the
grill:
Auto mode: Simply set your desired temperature
and the grill does the rest.
Manual/Smoke mode: Choose between 20 pre-
programmed settings (L1-L20) to nd your favor-
ite custom smoke setting.
1. Power - This powers on the grill from standby
mode. When you re up the grill this is al-
ways the rst button that you push
2. Mode - This button switches the grill between
auto mode and manual/smoke mode. The
grill always starts in the setting that was used
when the grill was last powered off. The grill’s
mode is indicated by the LED lights above the
mode button.
3. LED Display - By default the LED always
displays the grills cooking temperature set
point but will also temporarily display actual
temperature, meat probe settings and other
important information.
4. TEMP Arrows - Adjust the temperature, meat
probe or smoke setting of the grill up or down.
5. Probe - Pushing this button will display the
actual probe temperature (P) then will display
the SET TEMP (S) for the meat probe. You
can adjust the set temperature that you would
like your meat cooked to by using the Temper-
ature Control Pad. See “Understanding The
Meat Probe” later in this section.
6. Temp Display (PRIME)- Pushing this button
once will display the actual rebox tempera-
ture (Auto mode only). NOTE: Holding this
button down continually feeds pellets to
the burn pot.
7. Probe Input: Plug in the meat probe when
using the probe feature.
Starting Your Grill
1. Make sure that the hopper is lled with hard-
wood cooking pellets and make sure that you
have completed section 3 (initial priming and
seasoning).
2. Make sure your grill is plugged into an outlet.
3. Push the power button then, using the TEMP
arrows, select any desired cooking tempera-
ture. If you are cooking above 300°, we

8
recommend starting the grill on high (480°)
for 15 -20 minutes to quickly pre-heat.
4. Your grill will automatically run a lighting se-
quence that will last 9 minutes. You will notice
that the auto light will ash on the board dur-
ing the lighting sequence. Once the lighting
sequence is over the grill will begin to operate
at the temperature that you have selected.
5. If your grill fails to light after 15 minutes, un-
plug your grill, clean out excess pellets from
the burn pot and re-light.
Using Your Grill In Auto Mode:
You will almost always want use your grill in auto
mode. In auto mode the grill uses an internal
temperature sensor to adjust fuel and fan speed
allowing the grill to maintain the cooking tem-
perature that you select. To use the grill in auto
mode, simply push the power button and then
adjust the grill to your desired temperature using
the temperature control pad. If the grill was last
used in manual mode you will need to push the
mode button to return the grill to auto mode. Al-
low the grill to pre-heat for 15-30 minutes before
using. Important: to maintain your desired
cooking temperature, always use the grill with
the lid closed as much as possible. Opening
the lid too often will waste pellets and greatly
increase your cooking time.
Grilling. ~350°-480°
Grilling is done over high heat and is the way to
go for backyard staples such as steaks, ham-
burgers and hot dogs. For wood-red grilling on
your Madera simply power on your grill and set
to the desired grilling temperature.
Using the Quick Grill Zone
For high temperature grilling and searing you can
easily slide open the Quick Grill Zone by pulling
out the handle located on the right side shelf until
it stops. Place your food on the center of the grill
and sear it to perfection. When grilling on high
(480°), the center cooking grid will reach tem-
peratures over 600°. To close off the Quick Grill
Zone and return to normal barbecuing, push the
handle back in until it stops.
**Helpful Tip**
To get your grill up to grilling temperature
quickly, you can set the grill to high (480°) for
15 minutes then set the grill to your desired
grilling temperature (350° to 480°).
Barbecuing. ~220°-350°
To BBQ is to cook with indirect heat in a smoky
environment. Roasts, ribs, chicken and various
vegetables are excellent on the Barbecue. Great
BBQ is easy with the Madera. Be sure the Quick
Grill Zone is closed and using the TEMP control
pad, set the your grill to your desired BBQ tem-
perature. In about 15 minutes the barbecue will
be hot and ready. Load the cooking grids with
food, close the lid and let the Madera do the
rest. There’s no need to tend your food, turning
it often, or worry about it getting burned. That’s
the beauty of Madera design. Through convec-
tion the wood-re heat is distributed all around
the food, sealing in juices while cooking evenly.
When barbecuing, leave the lid closed. This will
help maintain a more even temperature, efcient
cook time, smoky avor and save your wood fuel.
For larger items, such as a big roast or whole
chicken, use the Madera meat probe for worry-
free barbecuing. Make sure you insert the meat
probe horizontally into the center of the largest
part of meat (e.g. - on whole chicken- the center
of the breast.) Your grill will turn down to 200°
and sound an alarm when the food is done (see:
“Using Your Meat Probe” below).
Slow Smoking. ~180°-220°
When your temperature is set below 300° the
Madera automatically adjusts fan speed for
smoking. You can also set the grill to manual/
smoke mode (MODE button) and use the TEMP
control pad to select your favorite smoke settings.
Preparation for slow smoking in your Madera is
similar to barbecuing. With the Quick Grill Zone
closed, set the Madera controls to your desired
temperature and load the grids with food. Re-
member that some smoked foods need a longer
cooking time so be sure to ll your pellet hopper
before smoking. When smoking at low tem-
peratures (below 180°) extreme care should
be taken to ensure bacteria does not grow on
food. If you are unsure about how to properly
smoke meats, only use your grill at low tempera-
tures to smoke sh, nuts etc.
A tip to help achieve your desired level of smoke

9
avor is to combine a slow smoke session with a
grill or barbecue session. You can smoke a whole
chicken at 180° for an hour then finish it off by
barbecuing at 350° until done. You can also bake
in your Madera. It will achieve as even a tem-
perature as your kitchen oven, and makes excel-
lent pizza, calzones and breads. As a rule, the
higher the temperature your Madera is set to the
less smoke it will produce. Thus, a pizza cooked
at 425° will have just a hint of brick-oven smoke
avor. Desserts like oatmeal raisin cookies and
apple pie are uniquely delicious when prepared in
the Madera.
Using Your Grill In Manual/Smoke Mode
Use this mode to vary the intensity and avor of
your smoked foods. In Manual Smoke Mode the
grill does not use the internal temperature sensor
to maintain a precise temperature, rather in uses
pre-set feed rates for more controlled smoke
production. This mode can also be used if your
temperature sensor fails and you are waiting for a
replacement. The temperature of the grill will vary
depending on the outside (ambient) temperature
and how long the grill is on.
To use the grill in manual mode, push the power
button then push the mode button. You will see
the LED light switch from Auto to Manual and
the display will read the current smoke level (L10
by default). Use the chart below to determine a
good smoke level:
Feed Rate Approximate

L18 390° little to no smoke
L19 440° little to no smoke
L20 500° little to no smoke
*These are the recommended settings for most
manual smoking
Tips For Smoking In Warm Weather
Your Madera grill is very well insulated which
means you will cook with less fuel and more even
temperatures. This also means that in warmer
weather (70° and above) it can be more dif-
cult to achieve low temperature smoking (below
200°). If you nd that the grill is running warmer
than you would like, you can switch to manual
mode and place the grill on L1 which will feed the
lowest amount of pellets possible. If you require
even lower temperatures you can prop open the
lid of the grill 1-2” to allow excess heat to bleed
off, lowering the temperature of the grill. For
even lower temperatures see the advanced user
features at the end of this section.
Low Temperature Warning
When the grill is reading very low temperatures
(below 150°), an alarm will sound every minute
warning you that the grill may have gone out.
Low temperatures can be caused by high winds
or the lid being left open for an extend period of
time. If this is the case, protect the grill from wind
and/or close the lid and the grill will continue to
operate normally. It can also mean that the grill
has gone out. If the grill has gone out, shut the
grill off, unplug and check the hopper to see if
you have run out of pellets.
If You Run The Grill Out Of Pellets.
Try to always watch the level of fuel in the pellet
hopper so that you do not run the grill out of fuel.
If you do, you will need to re-prime the auger feed

10
tube just like you did when you lit the grill for the
rst time:
1. Fill the hopper with quality hardwood cooking
pellets. Place 1/2 cup of pellets directly into
the burn pot
2. Power on the grill (any temperature setting).
When to use the meat probe
Using the meat probe allows you to barbecue
your food to an internal temperature that you se-
lect. Use the meat probe when you are cooking
larger cuts of meat such as roasts, whole turkeys,
and brisket. For checking the internal tempera-
ture of smaller cuts like steak, chicken thighs, and
sh, we recommend using an instant read hand-
held BBQ thermometer.
Understanding The Meat Probe Display
Push the probe button and the LED Display will
cycle 4 pieces of information:
P - 0 8 0 - S - 000
P- Stands for PROBE TEMP and the number
that follows will be the current temperature that
the probe is reading.
080 - This is the lowest temperature that the
probe will read. As your meat cooks this number
will change telling you in real time what the inter-
nal temperature of your meat is.
S- Stands for SET TEMP and the number that
follows is the temperature that you will set your
meat to be cooked to.
000 - This SET TEMP number is adjusted by
pushing up or down on the Temperature Control
Pad. 000 means that the probe is off. 080 is the
lowest temperature that can be set for your meat.
240 is the highest temperature that can be set for
your meat.
Using your meat probe.
Before setting your probe see the cook time chart
below to determine the minimum safe internal
temperature for different cuts of meat.
Step 1: Insert the meat probe plug into the input
located on the face of the Digital Control Board
Step 2: Insert the probe through the exhaust vent
on the side of the grill and into the thickest part of
your meat.
Step 3: Fire up your grill and set your desired
temperature just as your normally would.
Step 4: Push the probe button once and you will
see the LED display cycle the probe informa-
tion. When the set temp (S) is displayed, push
up on the Temperature Control Pad to select
your desired internal temperature (80°-240°). In 2
seconds the display will default back to the cook
temperature set point.
Step 5: You can monitor your meat’s internal
temperature by pushing the probe button at
anytime. When the probe senses that the meat
reaches the internal temperature that you have
set, the grill will sound an alarm and display
“OFF” notifying you that the meat is done. The
grill will then automatically turn down to 200°. If
you would like to adjust your probe temperature
at any time, simply push the probe button again
and re-adjust using the temperature control pad.
Step 6: To turn off the probe, simply turn the
probe set temp (S) down to 000 or shut off the
grill.
Thoroughly wash your meat probe with warm
soapy water in between each use.
