Great Outdoors Smoky Mountain Propane Smoker

GOSM Wide Body  Propane SmokerI am assuming that you have already put the thing together and seasoned it – You can read a short tutorial on seasoning a new smoker here if you need to before we move on.

I am also going to assume that you have properly prepared some meat for smoking and have it ready to go into the smoker all rubbed down with Jeff’s Naked Rib Rub.

Step 1 – Hook up the propane tank (remember righty loosy – lefty tighty) and make sure it is snug. Propane as with all fuel gases use left handed threads.

Step 2 – Open the door of the smoker by turning the handle 90 degrees counter clockwise.

Step 3 – Remove the smoke box, fill it full of mesquite, hickory, oak, apple, cherry, etc. wood chips or chunks. Replace the lid on the smoke box and return it to the wire frame cradle just above the burner where you removed it originally.

Step 4 – Get a large piece of heavy duty foil and line the water pan which is located just above the chip box. If you make this step into a habit it will save you lots of time cleaning all of the goo out of the water pan. You can simply remove the foil and dispose of it leaving a clean water pan ready for your next smoke.

Step 5 – Go into the house or if you’re lucky, the sink in your outdoor kitchen area and fill a half gallon pitcher full of hot water and then go back to the smoker and pour the water into the water pan that you just lined with foil.

Step 6 – Now for the fun part!  Turn the large knob on the left a few clicks and make sure it is spitting a spark next to the burner. If no spark is coming out then feel below the control area (the area just below the two knobs) and find a wire; make sure its securely connected then try again. You may need to contact the company if you are still having problems.

If it sparks properly, turn the right side knob to high (start) and immediately turn the left knob a few clicks to ignite the propane burner.

Step 7 – While the smoker is coming to temperature, you need to make sure the vents are set properly. If you have the type with two lower vents then set them to closed at the tab stop which is the “GOSM” way of helping you to not make a mistake by closing them all the way.

Now set the very top vent to the same position of closed at the tab stop.

You may have the type with only the top vent and if so then simply set it to closed at the tab stop.

I know some folks who have learned that with certain milder woods they can get more smoke flavor by bending up the stops and closing the vents a little more.

For now, leave them be and stay on the safe side.

Note: it is extremely important on ANY smoker to set the vents correctly to allow proper airflow into the smoker and out of the smoker. This allows your fire to burn properly and lets the smoke “kiss” your meat without settling on it and building up creosote.

Step 8 – Let the smoker continue to burn on high for a minute or so then lower it to an area between low and medium to allow it to settle in at 225 degrees.

Step 9 – The wood will start smoking in about 4 or 5 minutes maybe even sooner so you want to quickly get your meat into the smoker.

If I am only smoking a small amount, I will use the rack at the same level as the thermometer to make sure I know what the exact temperature is at meat level.

If you are loading it down then make sure to leave a little room between the meat to make sure everything is smoked properly with plenty of room for airflow.

Step 10 – Once you have the meat in the smoker, close the door and latch it by turning the handle 90 degrees clockwise.

Step 11 – Sit back for about an hour or so with your favorite beverage, checking occasionally to make sure it is maintaining your target temperature and make small adjustments as necessary.

You will find that it sometimes takes as much as 2 or 3 minutes for the temperature to level out once you make a change so make a very small change and then wait to see what happens.

With practice you will find out exactly where to set it to maintain a certain temperature.

You will also notice a difference based on how much meat is in the smoker- a smoker full of cold meat will take more heat to reach and maintain temperature than a smoker with only one pork butt in it.

Step 12 – After about 1.5 hours you will probably need to add more chips/chunks to the chip box. Just before the wood completely burns up and stops giving off smoke it will start smoking very heavy; this is a tell tale sign that it is almost time to add more wood.

Quickly and carefully open the door and with some heavy duty tongs (big channel-lock pliers also work great) and a welding glove or something similar, pull out the chip box carriage and remove the lid, then the chip box with the pliers or whatever you are using and set it on the ground.

Quickly close/latch the door so it can maintain heat while you are replacing the wood chips/chunks.

Step 13 – Pour out the ashes and pieces of coal still in the chip box into a metal container making sure there is nothing that can catch fire within the vicinity.

Refill the chip box with chunks or chips and return it to the chip box carriage in the reverse order of removal as quickly as possible to minimize heat loss.

For ribs, poultry, etc. you will probably only need to replace the wood one time but for larger cuts like brisket, pork butt, etc. you may need to do it 2 or 3 times.

A good way to measure it is to keep replacing wood until the temperature of the meat reaches 140 degrees and it will be about right.

Step 14 – When the meat reaches time to be almost done based on a digital probe meat thermometer or a tenderness test depending on your personal method get yourself another cold beverage and hang out around the smoker so you can be ready to pull the meat out when it reaches perfection.

Here are some times and temperatures that I use:

Ribs
Time – 6 hours
Target Temperature – 170 degrees

Chicken
Time – 4 hours
Temperature – 167 degrees

Turkey (12 pounder)
Time – 6.5 hours
Temperature 170 degrees

Pork Butt/Pork Picnic
Time – 1.5 hours/pound
Pulling Temperature – 205 degrees
Slicing Temperature – 160 degrees

Brisket
Time – 1.5 hours/pound
Thick Slicing Temperature – 190 degrees
Thin Slicing Temperature – 180 degrees
Tip – If the brisket is tough slice thin and against the grain, if the brisket is falling apart tender slice thick with the grain.

Step 15 – Turn the knob on the right to the OFF setting and then turn the propane tank off by turning it clockwise until it stops turning.

Step 16 – Carefully remove the meat from the smoker and carry it to your kitchen or wherever you are planning to prepare it for eating (i.e. slicing, pulling, etc).

Step 17 – Go back out one last time to make sure the smoker door is shut and latched, and that all ashes and hot coals have been cooled down with water and are incapable of starting a fire. (That would pretty much ruin your day!)

Step 18 – Enjoy the food and the praise!

    can i convert this smoker from propane to natural gas?

    • TulsaJeff
      September 29, 2009 | 12:22 pm

      It can be converted although I have not performed the task myself.. I hear you can drill the holes (orifices) in the burner about 2 sizes larger and remove the regulator to accept natural gas but I would certainly check with someone who knows a little more about the subject before attempting this.

      You may also need a regulator if it is not regulated at the meter.

      There will also be kits that will convert the propane over to NG if you look online.

    I recieved the smoker as a gift, used. It did not come with the manual. I was really stuck because I could not get the heat up. It turns out the you must turn the dial to off, before the full flame will happen on full.

    Thought it might help save someone the hours of frustration it caused me.

    While this article recommends keeping all three dampers nearly closed, I have to disagree as less air flow promotes incomplete combustion and creosote formation, leading to bitter meat and a smoker lined with resinous goo. If you preheat your chips or chunks and don’t soak them in water, you can get away with choking off the vents a bit but that shouldn’t be attempted until normal air control with moderately open vents has already been mastered.

    • TulsaJeff
      March 3, 2010 | 10:15 pm

      The vents have a stop which will not allow you to close them all the way. They should be closed all the way to the stop for best results.

      Closed to the stop leaves them open enough for more than adequate airflow. I agree in most cases, you do not want to allow a smoker of any kind to be left with no way for air to flow into the smoker and back out. As you have pointed out, this is a setup for major creosote.

      Thank you Fred for the comment as it shows the post may have needed some clarification.

    These instructions are a whole lot better than the ones that come with the smoker. The one with the smoker left out the part about spraying oil on the inside surfaces. I also like the temp and time chart included that was not with the one that came with the smoker.
    Is there a particular way to load the smoker and what meat should be higher than others if smoking multiple meat choices?

    I have enjoyed my Smokey Mountain Gas Verticle Smoker for 4 years. This year it started producing a fine black soot from the burner. It accumulates on the bottom of the wood chip box as a fine black powder. Unfortunately it accumulates on the meat as well. Would you know how I can fix the problem? Thanks.

    Just bought this smoker. My wood chips burn out after about an hour, even when wet. Is burning one box of chips sufficient or should I keep replacing them? It took me about 12 hours to smoke a pork shoulder the other day and I’m worried about constantly opening and closing the door.

    I find your instructions are very complete except you give none for smoking Salmon.
    the way I have been smoking Salmon is to keep the temp. between 160 to 170 degrees. I put 5 8 pieces on 1 rack. 3 racks would be for 15 to 24 pieces. I try to fill them making sure I leave enough space between each piece. I have left them on betweem 8 and 20 hours depending on how think they are. I soak the Salmon in a brine for 2 or 3 days before smoking useing garlic, salt, brown sugar, a little paprika to make the Salmon darker looking. Then I leave the Salmon out for about 1 to 2 hours before smoking. It seems to smoke better if it is a little dried out before placed in the smoker. Could you give me your thoughs on smoking salmon. Thanks Tom

      Paul,

      I had the same problem a while back since storing my Big Block GOSM in the barn for a while. I had flames shooting out of the gas line in multiple places.

      I figured there was a blockage somewhere that was preventing the normal flow of gas through the line so I took the burner off the smoker and blew out the lines with high pressure air and tapped the burner on the concrete lightly to knock out any dust or debris. I also poked a wire up in the gas line toward the burner to make sure there was no obstructions.

      When I put it all back together it worked like a charm. I can only assume that you would have the same good fortune if you replicated this procedure.

    We recently bought a propane smoker and lost the operating instructions. It has 2 side vents and one top vent. You mentioned in your article to open the vents to the tab stop. Our smoker does not have such stops. Can you tell me about how much of an opening that would be?
    Thank you.

    • TulsaJeff
      October 17, 2010 | 4:21 pm

      On my smoker, the vents are round and the opening are pie shaped. Each opening is about 1″ at it’s widest point when closed all the way to the tab stop. This seems to be a perfect spot with plenty of air coming in at the bottom and plenty of smoke flowing out at the top to prevent creosote buildup due to inadequate airflow.

    What no input on smoking fish . What temp and how long

    • TulsaJeff
      October 18, 2010 | 5:59 pm

      I’ll get something on fish eventually. For now, you should smoke whole trout at around 225 degrees F for 2-3 hours or until the meat reaches 145 degrees. If you wait until it flakes it may be overcooked.

      Salmon is best cooked really slow to keep the fat from cooking out of it. Keep the smoker temperature around 150 degrees and it could take 5- 6 hours. The salmon is done when it reaches 145 degrees.

      For best results use apple wood or alder with fish.

    I am smoking a 5.5lb brisket right now. It’s my first time using this smoker and I’m able to keep the heat steady, between 200-225 no problem. However, I can’t get any smoke. I started with the wood-chip box filled with water-soaked wood chips for about an hour, and then dumped out the charred chips and switched to dry wood chips, but still no smoke. suggestions?

    • TulsaJeff
      May 28, 2011 | 3:41 pm

      I usually turn the heat to high until I see smoke, then I turn it down to maintain my temperature. Now that you have food in there, just turn the heat on high and crack the door open about 1/2 inch or so to maintain your temperature until you see smoke. Once you see smoke you can close the door and set it to maintain 225 or so.

      I am assuming you have the cast iron box for the chips.. those take a little while to produce smoke and the heat must be on high for several minutes before this happens. If you want smoke a little faster (less than a minute usually) find a large metal coffee can and cut the top down a little bit with tin snips or a rotary cutting tool so that it will fit where your original smoke box is now. The metal is much thinner and all of the heat goes to getting the chips to smoking instead of heating up a bunch of thick cast iron.

      I always use dry chips or even chunks in my propane smoker.

    I am a rookie smoker – I just bought the Smoky Mountain 30″x24″ smoker last week, and let me tell you – I am impressed with this one. Contrary to what many reviewers have said, the temperature gauge is quite accurate. I recommend keeping a hanging thermometer inside the smoker to ensure its accuracy. Per many suggestions, I wrapped the water pan completely in foil. I also bought a cheap 9″ steel bread loaf pan for the wood chips – I wrapped this in foil as well and use a piece of foil with holes poked in it for the cover. I turn my propane tank a 1/4 turn and run the regulator juuuust slightly above the lowest setting with the damper as closed as it can get (still somewhat open). I put in a pork shoulder last night, woke up this morning after 7 hours and was nervous to check the temp. 220 degrees on the dot. BOOM. It maintained temperature perfectly. For $140 from Walmart, you can’t get a better value for a propane smoker!

    I have the 30 x 24 smoker and have really enjoyed smoking. I have a question though about time and temperature. At the lowest setting my oven reachs 225 degrees. The internal temperatures of my meats seem to rise continually to about 150 degrees. Then they stall and rise very, very slowly. They take me well past the predicted times. I’ve been turning the heat up at this point to get the meats at the reccomended temperatures.
    Should I start my cooking at a slightly higher temperature? Is this normal?

I had it plumbed into my propane system for my stove and water heater, etc. I have a question. If I want to smoke some things at lower temps is it OK to reduce the gas entering the smoker using the valve from my gas system? The lowest temp I can achieve now is about 185-90 degrees and I’d like to get it down to about 165-70 for some things. Thanks for your responses!

    I just received the smoker as a gift after using a charcoal smoker for a long time. Problem I have is that it won’t produce smoke at any less than 350 degrees which is way to hot to smoke. And at that temperature the chips burn dry or soaked. Any ideas? Pretty frustrated why my new smoker won’t make smoke!

    • TulsaJeff
      January 2, 2012 | 11:46 pm

      I have found that the best way to get the smoke going is to place the food on the grate then leave the door cracked open a few inches and leave the smoker on HIGH until a good amount of smoke is flowing out. The door being cracked open keeps the heat at a minimum inside the smoker. At that point you should be able to close the door and turn the smoker down to a more medium setting. If that does not work as well as you’d like, find a metal coffee can, cut it down shorter if you need to but use that in place of the smoke box that comes with the smoker. The thin gauge metal of the coffee can will get the chips to smoking a lot faster.
