Initial Setup Procedure
Before cooking for the first time, we recommend that you remove the cooking grate and wash it with
mild soap and water. Fill your hopper at least halfway up and place a small handful of pellets into
the fire pot, enough to cover the igniter. Do not over fill the fire pot. Reinstall the grate, set grill to
400°F and once the grill reaches 400°F, let run with the lid down for 1 hour. This will provide a final
cure and remove any residue that may have accumulated during manufacturing and shipping. After
this initial burn, your auger and fire pot are primed, and your grill is ready for cooking.
Operating Your Grill
Power Button:
Press power button to turn grill on and adjust temperature knob to desired temperature.
• Turning the grill ON activates the automatic startup mode and illuminates the digital readout.
• If your grill fails to light itself within 30 minutes of startup, the Smart Grill Technology™ processor
will turn the grill off and display ER-2 on the screen.
• Pressing the power button again activates the shut down mode of your grill. If grill’s actual
temperature is below 160°F, pressing the power button will simply turn the grill off.
• When the power button is used to shut down your grill, the Smart Grill Technology™ processor
will stop adding pellets to the fire pot and the fan will continue running to completely burn the
pellets remaining in the fire pot. During this cooling process, the display screen will display FAN.
Shortly thereafter, the display screen will change to display AUG - this will push out any embers
left in the auger tube.
WIFI: Download recteq app from Apple App Store for Apple devices or Google Play, and follow
the directions on app.
WIFI Troubleshooting: Go to recteq.com/wifi-setup
Temperature Control Knob: Turn knob to select computer maintained temperature in 5°
increments. (Range: 200°F - 500°F)
Additional Temperature settings: LO and FUL
LO: LO will display as actual temperature when knob is turned counterclockwise beyond 200°F and
Xtreme Smoke will be activated. The grill will feed pellets to the fire at the minimum feed rate (lowest
rate possible to maintain a reliable fire). This will produce the most smoke and achieve the lowest
temperature possible, given environmental conditions/type of pellets used.
FUL: FUL will display as actual temperature when knob is turned clockwise beyond 500°F. Grill will
feed pellets to the fire at 100% of auger capacity. This will produce the highest temperature possible,
given environmental conditions/type of pellets used.

Operating Your Grill
Settings Button: Press and hold the setting button to access the adjustable parameters menu. Short presses
of the settings button will scroll through the adjustable parameters. Pressing and holding the settings button
will exit the adjustable parameters menu.
Test Mode: With grill OFF, press and hold the Settings Button to enter the Adjustable Parameters Menu.
Enter Test Mode from either of the four screens AUG, OFS, PrA, or PrB by pressing the Power Button. Each
additional press of the Power Button will advance you through the 8 Test Mode screens. The last screen is
the BYE screen. While on the BYE screen, press the Settings Button to return to the adjustable parameters
screen then press and hold the Settings Button and your grill’s controller will return to the OFF state.
Adjustable Parameter 1: Min Feed Rate - Min Feed Rate
is the minimum rate that the auger is allowed to feed fuel to
the fire pot, regardless of Set Point. Decreasing the value will
allow the grill to achieve lower temperatures but will increase
the risk of flame-outs. Increasing the value will prevent losing
fire but will limit your ability to maintain low temperatures
on hot, sunny days. Note: Changing this does not change the
auger speed. The auger speed is constant.
Adjustable Parameter 1 controller will display AUG.
Additionally, the current auger minimum feed rate will be
displayed as a number. Turning the Temperature Control
Knob clockwise will increase, and turning counterclockwise
decrease, the value within the range of 5 - 250. (Factory
preset: 30)
Adjustable Parameter 2: Temperature Offset - Your
grill has been precisely calibrated at our facility, but the
Temperature Offset allows you to customize how your
controller will operate. Should you choose to rely on a
secondary temperature probe, you can use the following
process to recalibrate your Smart Grill Technology Controller.
Adjustable Parameter 2 will display OFS.
Additionally, the current temperature offset percentage
value will be displayed. Turning the Temperature Control
Knob clockwise will increase, and turning counterclockwise
decrease, the value within the range of -25.0 to 25.0.
(Factory preset: 0)
Due to varying qualities of pellet brands, we give you the ability to adjust your minimum feed
rate downward in the event that your grill is running hot at lower temperatures. However, if you
experience a sudden loss, followed by an immediate increase in grill temperature, then your grill
has experienced a flame out and will automatically relight. This signifies that your minimum feed rate
was adjusted too low and needs to be increased.

Shutting Off Grill
When you are done cooking, simply press the power button. The blower fan will start to cool
your grill down and will shut off on its own. The auger will feed pellets during the process; this is
completely normal. Keep lid closed during this process. Do not move until fully cooled.
Tips, Tricks, and Temps
Preheating
It is important to allow your grill to preheat to achieve your desired cooking temperature before
cooking. This allows the entire grill to heat up and quickly return to your desired temperature
once your food is introduced. If you do not allow the grill to preheat, you will find that it takes a
longer period of time to bring both the grill and the food to your desired cooking temperature. It is
important to leave the lid closed during preheating.
Pellet Information
Ultimate Blend premium hardwood pellets contain approximately 8,200 BTUs of heat per pound
and leave less than 1% ash residue. Pellets should be stored in a dry area, as wet pellets will swell
and turn back into sawdust. For the best results, always use premium hardwood pellets in your grill.
The use of grades other than premium hardwood pellets may result in temperature variations, uneven
cooking, and poor results. Remember, pellets do not contain preservatives and will deteriorate over
time.
Caution: Some wood pellets produced for heating fuel have a high content of softwood which can
include pitch and should not be used for cooking. Always check with the pellet manufacturer to
ensure that you are cooking with a premium, 100% hardwood pellet.

• Clean your grill regularly to maintain beauty and proper function. It is advised to clean before
any long cook.
• Always use grill on a level surface.
• Check and clean fire pot regularly; this will ensure proper ignition and heat output.
• Not all pellets are created equal; always use dry and fresh pellets.
• Always store pellets in a dry area.
• Get to know your grill and keep good cooking notes. This will help with consistency.
•Practice makes perfect.
• Always allow your meat to rest before serving.
• Always keep your cooking area clean.
• Avoid lifting the lid more than necessary.
• Wind can cool your grill temperature.
• Always preheat grill to desired temperature before use.
•Wipe off stainless steel surfaces before preheating; dirt and food stains can cook into surface.
• Always check pellet hopper for debris and remove excess pellet dust as needed.
• Leave at least one inch of clearance between food for even cooks (crowded foods will take
longer to cook).
• Foods cooked in pans or containers will require more time than foods cooked directly on grate.
• Use your platinum-tipped meat probe to determine meat-doneness; never rely on time.
• Know your food’s internal temperature.
• Use long handled tongs and spatulas for turning meats; do not use plastic utensils.
•Injecting, mopping, and spritzing are great ways to keep meat from drying out.
•When going low and slow, plan for your meats to stall; larger pieces of meat tend to take
longer from160°F-180°F. Be patient.
• Never unplug your grill to turn it off.
• When not in use, unplug and cover with recteq Premium Grill Cover.
Temperatures
Remember, you can’t tell whether meat is safely cooked by looking at it. Any cooked, uncured red
meats (including pork) can be pink, even when the meat has reached a safe internal temperature.
After you remove the meat from your grill, allow it to rest for a specified amount of time. During the
rest-time, its temperature remains constant or continues to rise, which destroys harmful bacteria.
• Hot foods should be held at 140°F or warmer.
• Cold foods should be held at 40°F or colder.
• Perishable foods should not be left out for more than 2 hours at room temperature; 1 hour when
the temperature is above 90°F.
• Always follow food safety guidelines provided by the USDA.

Maintenance & Cleaning
• Clean your fire pot every 3-5 cooks or after every 16 hours of cooking time, to ensure proper
airflow.
• Use a grill brush to clean your cooking grate after every cook to provide years of trouble-free
use.
Note: Make sure that no bristles have shed onto the cooking grate.
• Clean the ash from the interior of your grill after every 2-3 bags of pellets.
WARNING: Always wait at least 12 hours after cooking to remove ash from your grill!
• Use a mild soap and water to clean the exterior of your grill.
AVOID USING CAUSTIC CLEANERS!
• If left in an exposed area, keep your grill covered and unplugged when not in use.
• Never let your pellets get wet; they will swell and jam your auger.
• If grill is not used for 6 weeks or more, it is advised to remove all pellets from hopper.
Never store the grill in a small space or place in a vehicle unless completely cool and fire is verified
as extinguished. Never move the grill while it is still hot. Never move the grill without assistance.
Clean the ash from the interior of your grill, fire pot, and hopper every 5-6 bags of pellets – a shop
vac is an ideal tool for this job. It also helps to leave a thin layer of ash on the bottom of the barrel
for insulation.
If you have completed a low and slow cook that has caused the accumulation of grease on your
foil, you must change the foil before cooking at high temperatures!
Failure to do so will most certainly cause a grease fire in your grill.

Troubleshooting
In case of igniter failure, you can start your RT-700 manually:
1. Remove the stainless steel grates, drip pan, and heat deflector.
2. Clean out fire pot and place no more than 1/2 cup of pellets in the bottom. Add a
small amount of solid fuel fire starter, such as those made from sawdust and wax, or
use wood shavings.
Tip: A paper towel, shredded cardboard, or shredded newspaper can work as a
substitute.
If you have a torch lighter, a fire starter is not needed.
3. Light the fire starter.
4. After the pellets are burning briskly, turn on your grill. If your fire goes out, repeat
steps 1-4.
5. If your fire stays lit, replace the stainless heat deflector, drip pan, and cooking grates
then close the lid.
Be careful not to touch the fire.
CAUTION: Do not use flammable liquids such as gasoline, gasoline-type
lantern fuel, kerosene, charcoal lighter fluid, or similar liquids to start or
freshen-up the fire! Keep all such liquids well away from the grill while it is in
use.
