CHIMP WOOD PELLET GRILL OPERATION MANUAL2
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 lightbulb 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 two guys, 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 Chimp was born.
Just like a silverback is the proven and respected leader in a family of mountain gorillas, so
too is Chimp the patriarch of the Grilla family of smoker-grills. No confusing Chimp with any of
these flimsy me-too grills. Been there, done that.
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. Not bad for
two fishing buddies. Enjoy!

CHIMP WOOD PELLET GRILL OPERATION MANUAL4
SAFETY INFORMATION
• The unit is for outdoor use only. Never use the
Chimp in an enclosed area.
• For safe assembly, use at least two people to
unpack and assemble the grill.
• Keep young children and pets away from the grill
while it’s in use.
• Always use heat-resistant hand wear when
touching or handling the grill while it’s in use.
• Keep the grill at least two feet away from any
combustible surface.
• Never use ammable liquids such as gasoline,
charcoal lighter uid, kerosene, or similar liquids to
start or freshen the re in your grill. Keep all such
liquids well away from the unit while it is in use.
• Clean the grill on a regular basis. Clean the
unit’s drip tray and ensure that the grease drain
is able to function properly (i.e., not on an uphill
slope on a deck or patio). Should a grease fire
occur, turn the grill off, unplug it, and then close
the lid until the fire extinguishes.
• Never place flammable items in the grill’s
storage area.
• Install the service access panels (under the
grill’s pre-installed shelf and on the rear) before
plugging the unit in. Always keep the unit’s
shelf-side louvers clear of any obstructions.
• Never put your hand in the pellet hopper or
attempt to service any part of your Chimp while
the unit is plugged in.
• Check your Chimp for re pot obstructions
occasionally. This will help maintain proper airow.
• 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 grease
catch evenly, as hot air displaced to one side or
the other will cause irregular operation.
• Never move the unit while it is hot and/or in
operation. Make sure the fire is completely
out and that the grill is completely cold before
being transported.
• Never move the Chimp when the pellet hopper is
full. The unit can be become top-heavy and may
tip over if moved.
• Clean temperature sensor occasionaly to ensure
proper temperature readput.
It’s important that you read all of the safety information in this manual before operating your new Chimp grill.
Congratulations on your purchase of a Chimp grill! Used and cared for properly, this grill will give you years
of enjoyment and trouble-free operation. Before assembling and using your new grill, please review the
information in this manual thoroughly. In it, you’ll find many useful tips to help maximize your Silverbac’s
long list of benefits and features.
Your Chimp is much more than just a traditional grill. In fact, you can cook almost anything on this grill.
Try pizza, marinated vegetables, casseroles, or bread — or, stick to the basics like steaks, roasts, hams, pork
chops or tenderloins, wild game, and poultry.
Using advanced technology, the unit adjusts the rate at which pellets are introduced into the fire pot in
order to keep the temperature consistent and predictable. Because of this, the Chimp is the easiest and most
convenient way to grill, cook, bake, slow smoke and roast food while also adding flavors that can only be
generated by a wood fire. Set your grill’s temperature and let it do the rest.
Thank you for choosing a Chimp Grill!

Chimp 101: How to Operate
Your Chimp.
Follow these operating instructions exactly as stated to ensure safe and reliable operation. Carefully read this manual
in its entirety before starting your Chimp for the rst time.
Getting Started
You will need to season your Chimp before you cook on it for the rst time:
Operating Your Chimp
1. Clean upper and lower cooking grates with
soap and water.
2. Fill hopper with approved cooking pellets.
3. Plug Grill into 110 Volt AC grounded outlet.
4. For your rst start, remove the Lower Cooking Grate
(8), Grease Pan (6), and Heat Bae (5).
5. Turn Grill on, and the igniter rod should turn a light
red in 1 to 2 minutes (do not touch).

and have started dropping (roughly 2 to 4 minutes),
turn OFF the grill.
7. Place components back in place and restart the grill
by turning the grill on.
8. This procedure is not necessary again unless
the grill runs out of pellets and it needs to have
the tube “re-primed."
9. Set temperature to 450°F and let the grill run
for 45 minutes.
1. Check hopper for debris and add pellets
as necessary.
Warning — remove the grease can
before movement of the grill to

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 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 grease tray.
• 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 fifth bag of wood pellets, clean the ash from the interior of your grill, empty hopper and
vacuum out debris (a shop vacuum cleaner is the perfect tool for this job).
• Clean inner temperature probe.
• Don’t ever use wet pellets in your grill as they will swell and jam your Silverbac’s auger.
• Once the grill is completely cooled, clean its outside with automotive wax, per the product’s directions.
• 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 stainless steel parts.

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.
General specications for barbecue pellets are:
There are dierent avors of wood pellets for your Silverbac.
Here is a table of wood pellet avor suggestions and what they go best with:
Mesquite Flavoring:
Mesquite, which means “the honey tree," gives a delicate, subtle, sweet flavor to grilled foods. It is
especially good with poultry and seafood.
Hickory Flavoring:
Hickory intensifies the flavor of food with a robust, tangy taste that is better suited to red meat than to
poultry or fish.
Apple or Fruitwoods Flavoring:
Apple or fruitwoods, many from orchards destroyed by re or old age, are a big hit. Like its mesquite counterpart,
the heaviest branches of the apple tree are heated to kill insects, then chipped, made into pellets and packaged
for retail. Apple (or any fruitwood) adds a smoky, mild sweetness to everything you cook and is highly
recommended for any baking.
Alder Flavoring:
Popular in the Northwest United States, alder produces a mild taste suited for salmon and other fish.
• 100% hardwood
• 1” long or less in length
• ¼“ diameter
• Less then 2% ash content
• Less then 2% fines
• Under 10 % moisture content
• Approx. 8,200 BTUs per lb
• About 40 lbs per cubic ft. density

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.
Why won’t my Chimp light?
Where do I get parts for my Silverbac?
1. Check outlet and verify Control Panel is
powering up.
2. Make sure green LED light is on. This ensures outlet
is good and fuse on the board is good. If not,
check outlet and unplug grill and check fuse.
3. Turn Chimp “O."
4. Remove Lower Cooking Grate (8), Grease Pan (6),
and Heat Bae (5).
5. Clean area of burned and unburned pellets.
6. Turn Chimp “On."
7. Verify Auger begins to turn and fuel is dropping
into Fire Pot. If Auger is not turning see
previous section.
8. 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.
9. Igniter should begin to turn red within
1 to 2 minutes.
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 5 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(8), Grease Pan (6) and Heat
Bae (5), and visually checking the Auger.
5. If Auger is not turning check fuse on back of
controller and replace as necessary. If good,
contact Grilla Grills 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 14.
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?
