SAFETY INFORMATION
Please read this entire manual before installation and use of the pellet fuel-burning appliance.
Failure to follow these instructions could result in property damage, bodily injury or even death.
Contact local building or re ocials about restrictions and installation inspection requirements in
your area.
SAVE THESE INSTRUCTIONS.
DANGER: Read carefully prior to use.
• Only use grill outdoors in a well ventilated area. Do not use in a garage, building, breezeway, tent, any other
enclosed area, or beneath overhead combustible construction.
• Do not use grill in any vehicle or in any storage or cargo area of any vehicle. This includes, but is not limited to, cars,
trucks, station wagons, mini-vans, sport utility vehicles, recreational vehicles, and boats.
• Do not put grill cover or any ammable on, or in the storage area under the grill while it is in use
or is hot.
• Should a grease re occur, turn o the grill and leave lid closed until re is out.
WARNING: Follow these guidelines to prevent this colorless, orderless gas from poisoning you,
your family or others:
WARNING: Warning on Installation Clearance:
• Maintain a MINIMUM distance of 36 inches (91.4 cm) from the grill to combustible construction at the rear,
side and top.
• A minimum of 40 inches (102 cm) is required when operating this grill under overhead combustibles.
• Know the symptoms of carbon monoxide poisoning:
headache, dizziness, weakness, nausea, vomiting,
sleepiness, and confusion. Carbon monoxide
reduces the blood's ability to carry oxygen.
Low blood oxygen levels can result in loss of
consciousness and death.
• See a doctor if you or others develop cold or u-like
symptoms while cooking or in the vicinity of this
appliance. Carbon monoxide poisoning, which can
easily be mistaken for cold or u, is often detected
too late.
• Alcohol consumption and drug use increase the
eects of carbon monoxide poisoning.
• Carbon monoxide is especially toxic to mother and
child during pregnancy, infants, the elderly, smokers,
and people with blood or circulatory system
problems, such as anemia, or heart disease.
• Only use your Grilla Grill outside on a
noncombustible oor and away from combustible
materials.
• Never use gasoline, gasoline-type lantern fuel,
kerosene, charcoal lighter uid, or similar liquids to
start or 'freshen up' a re in this appliance. Keep all
such liquids well away from the appliance when
in use.
UNPLUG GRILL WHEN NOT IN USE.

3CHIMP WOOD PELLET GRILL | OPERATION MANUAL
• For safe assembly, use at least two people to
unpack and assemble the grill.
• Children should never use the Chimp, as parts of
the Chimp may be very hot. Keep children away
while in use. Close supervision is necessary when
any appliance is used near children.
• The Chimp will become hot while in operation.
Keep persons, clothing and furniture away from all
hot surfaces.
• Do not store or use combustible materials,
gasoline or other flammable vapors and liquids in
the vicinity of Chimp.
• Never use ammable liquids such as gasoline,
charcoal lighter uid, kerosene, or similar liquids to
start or re-light the re in your grill. Keep all such
liquids well away from the unit while it is in use.
Burning improper fuel (i.e. charcoal) can result in
carbon monoxide poisoning, which may lead to
sickness or death.
• Caution when moving the Chimp when the pellet
hopper is full. The unit can be become top-heavy
and may tip over if moved.
• Never move or transport the unit while it is hot
and/or in operation. Make sure it is completely
cold before being transported.
• Position your grill on level ground. The grill should
be kept as level as possible so that the grease
flows into the trough and out into the can and
also to ensure that the sensor reads evenly, as hot
air displaced to one side or the other will cause
irregular operation.
• Follow Maintenance and Care instructions for
safety of user and optimal performance.
• Should a grease fire occur, turn the grill off, unplug
it, and then close the lid until the fire extinguishes.
• Do not touch hot surfaces. Use handles or knobs.
Use heat-resistant mitts or gloves, pot holders or
BBQ mittens when operating your Chimp.
• Keep a re extinguisher or water hose close
by for safety.
• Do not operate Chimp in the rain. Shield electric
digital Control Panel, keeping it dry and out of rain at
all times.
• To prevent Chimp from being splashed on or falling
into water, do not use Chimp within 10 feet of pool,
pond or other body of water.
• Do not use water or other liquid spray to clean
Chimp without rst shutting o unit and unplugging.
• Do not operate any appliance with a damaged cord
or plug, after appliance malfunctions, or if it has
been damaged in any manner.
• Never remove grounding plug, or use with a two-
prong adapter.
• Outdoor extension cords should be marked with
sux letter W-A and with a tag stating "Suitable for
Use with Outdoor Appliances."
WARNING: Electrical shock can kill or result in serious injury. When using electrical appliances, basic safety precau-
tions should always be followed to reduce the risk of re, electric shock and injury to persons, including the following:
WARNING: Direct contact with the Chimp fire chamber during operation may cause severe burns to a person's
skin. Never put water into the Fire Pot; it will jam the Auger, and possibly short out the Igniter.

OUR
STORY
True story: Two men on a fishing trip, chowin’ down at camp on a plate of ribs. One looks over
at the grill (he’s the industrial designer) and says, “Why do all those grills look the same, big ole
barrel cut in half?” The other, a metalsmith by trade, answers, “Because we haven’t built one.”
That’s when the light bulb went off. Why not design and build a smoker-grill that stands apart,
literally, from the crowd? Hundreds of design hours later, the Grilla was born.
Fast forward a few successful years: same idea. Only this time, bring a rock-solid, proven smoker-
grill to the market using the same streamlined business model that delivers savings to the
consumer. Design the grill to efficiently feed you and your friends or the entire neighborhood.
Make it easy to use and good looking. Hundreds of design hours later, the Silverbac was born.
It's not always convenient to haul a full size pellet grill around to the campground, family
gatherings or out to the park. We heard the wild calls of stomach rumblings from here and
answered with the no compromises Chimp pellet grill. Now you can beat your chest with pride as
everyone gathers around the deliciousness that follows you wherever you go.
All Grilla products, including pellets, sauces and accessories, are available direct to the hungry
consumer. No fat in this business model, just pure value meal after delicious meal. Enjoy!

About your new Chimp

7CHIMP WOOD PELLET GRILL | OPERATION MANUAL
Maintenance and care
Here are some maintenance and cleaning tips to help keep your Chimp running and operating smoothly. It may
be helpful to refer to the “Parts Diagram” in this Operation Manual to locate the parts on your grill discussed
below. Your Chimp can run efficiently for extended periods of time at different heat output levels, as long as the
wood pellet supply is uninterrupted and timely cleaning and maintenance is performed.
• Always make sure your Chimp is off, unplugged and cold before performing any maintenance or cleaning.
• Use a wire brush to clean your cooking grates after each use.
• Cover your drip tray with aluminum foil, and then change the foil frequently. This is the simplest way to
maintain your drip pan. Ensure foil is wrapped tightly around the drip pan, not to obstruct flow of air.
• If you have used a low-and-slow method that has caused the accumulation of grease on the aluminum foil, be
sure to change it before cooking at high temperatures (or risk causing a grease fire).
• After every other bag of wood pellets, clean the ash from the interior of your grill and fire pot, empty hopper
and vacuum out debris (a shop vacuum cleaner is the perfect tool for this job).
• Clean temperature sensor with a damp or lightly soapy towel regularly to ensure proper temperature readout.
• Never use wet pellets in your grill as they will swell and jam your Chimp's auger and can short out your
igniter.
• Use a mild soap and water to clean the grill’s powder-coated parts.
• Use a soft cloth and stainless steel polish to clean any of the grill’s exterior stainless steel parts.
• Never use stainless steel polish on the cooking grates.
For more Chimp maintenance and care information visit GrillaGrills.com
DISPOSAL OF ASHES: Ashes should be placed in a metal container with a tight fitting lid. The closed container
of ashes should be placed on a noncombustible floor or on the ground, well away from all combustible materials,
pending final disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be
retained in closed container until all cinders have thoroughly cooled.

TROUBLESHOOTING and faq
The Chimp is very trouble-free in operation when
properly maintained and quality fuel is used. If the
Chimp fails to operate properly, use the following to
troubleshoot.
Where do I get parts for my Chimp?
1. Check outlet and verify control panel is
powering up.
2. Turn Chimp “O."
3. Remove lower cooking grate (12), drip pan (11),
and heat deector (10).
4. Clean area of burned and unburned pellets.
5. Turn Chimp “On."
6. Verify auger begins to turn and fuel is dropping
into fire pot. If auger is not turning see
previous section.
7. If auger is turning but pellets are not coming
out, ensure there are pellets in the hopper. If it
ran empty or this is the rst time for use, it will
be necessary to prime the auger. This will ensure
pellets are at the end of the tube and will begin
dropping once unit is turned on.
8. Igniter should begin to turn red within
1 to 2 minutes. *Caution, igniter will be
VERY HOT.
1. Verify pellets are in the hopper.
2. If this is the initial firing or the Chimp has run
out of pellets, allow sufficient time for the
pellets to travel from the hopper to the fire pot
(may take up to four minutes).
3. Once pellets begin to drop, turn the
Chimp “Off” and then back “On” to
re-start Ignition Mode.
4. Ensure the auger is turning by removing the
lower cooking grate (12), drip pan (11) and heat
deector (10), and visually checking the auger.
5. If auger is not turning, unplug power and
check fuse on back of controller and replace as
necessary. If good, contact Grilla® or visit our
website to view support videos.
Be sure to be ready with your name, phone number,
address, Chimp model number and serial number,
along with the part identication number from the
“Parts Diagram” on page 8 and 9.
caution:Never squirt gel on a burning or hot fire.
caution:During troubleshooting some
components are hot. Allow unit adequate time to
cool. Use gloves as needed.
Pellets are not being delivered into the
Fire Pot – why?
For more Chimp troubleshooting information call Customer Service or visit GrillaGrills.com
Why won’t my Chimp light?
Three elements are needed for a re in your Chimp.
You need fuel, heat and air. Here are the things to look
for: Pellets? Auger turning to deliver the pellets? Fan
blowing air to the pot? Igniter heating up at start up?
Power?

15CHIMP WOOD PELLET GRILL | OPERATION MANUAL
APPROVED FUEL: wood pellets
Chimp is only approved for burning barbecue wood pellets. Wood pellets are small in size and generate about
8,200 BTUs per pound with very little ash and moisture content.
There are more than 125 active pellet mill operations in the United States and Canada, producing millions of pounds of
pellets each year. We have our own Grilla brand that we recommend. These all ignite easily and create great heat and
avor. Some brands infuse Charcoal or Alder wood which will burn hotter & faster and may cause issues.
General specications for barbecue pellets are:
• 100% hardwood
• 1”long or less in length
• ¼“ diameter or less
• Less than 2% ash content
• Less than 2% nes
• Under 10% moisture content
• Approx. 8,200 BTU’s per lb.
• About 40 lbs per cubic ft. density
CAUTION: Always store wood pellets in a dry location, away from sources of heat and other fuel containers.
• For best flavor, use Grilla Competition-Grade wood pellet fuel.
• Do not use pellet fuel labeled as having additives.
