Check Valve

1. GrillGuns are equipped with a gas-flow check valve, to stop or dramatically reduce the flow of fuel through it if liquid propane tries to enter the torch. Any time the torch is tilted on its side enough that the liquid propane in the bottle can flow into the torch or if liquid propane is trapped in the adaptor hose, the check valve will close and the only way to release the check valve it is to disconnect the fuel from the torch. You can then hold the GrillGun vertically and reconnect the fuel to gas connector and the GrillGun will operate correctly.

Handle Trigger Lock

2. The handle trigger lock is designed to keep you from inadvertently squeezing the handle trigger. The handle trigger bypasses the control valve to give you the ability to instantly provide full fuel force to the GrillGun, regardless of the position of the fuel valve knob.  Its purpose is to keep the handle trigger from being unintentionally actuated while holding the GrillGun.

Operational Safety Tips and Details

3. It is always a good practice to keep and store propane bottles and the GrillGun, disconnected from each other when not in use.
4. Always teach someone how to properly operate the GrillGun, before allowing them to handle it.  Only allow someone who is capable of properly handling, understanding and respecting the output power of the GrillGun, to handle and operate it.
5. The GrillGun has the potential of burning something up to 5 feet away from the end of the barrel.  Never point it at something that you don’t intend to burn.
6. Always operate the GrillGun with the propane tank upright, where only propane gas will enter into the GrillGun.  Do not invert or otherwise allow liquid propane from the bottle or hose to enter the GrillGun. The built-in check valve will stop the flow and you will need to hold the GrillGun upright again and remove the propane connection in order to all the check valve to release.
7. If the check valve were not in place, attempting to operate it either inverted or tipped over far enough on its side, such that liquid propane could enter the GrillGun, would also allow it to also exit through the barrel as a burning liquid. The burning liquid would travel much further than the burning gas (up to 5 or 6 feet), much like a flame thrower would.  This action not only carries the liquid propane from the gun but also any small solids floating in the propane, which could clog the output orifice or foul the valves, requiring you to have the GrillGun serviced to clean out the lodged debris.  While this action would cause no permanent damage to the GrillGun itself, it is both a dangerous practice and potentially a source of frustration for you to have your GrillGun, rendered inoperable.
8. The end of the GrillGun is called the Fire Bell, and it will be quite hot after operating the GrillGun.  Allow it to cool down completely before touching or allowing it to come in contact with a flammable surface.
9. While GrillGuns clearly look “really cool” they are very serious tools.  You don’t use big torches like these without needing to assume all the responsibility for using them safely, responsibly and taking care to fully understand how to use them correctly and how keep them from getting into the hands of small children or other persons that clearly don’t understand the destructive power they are wielding nor have the self-control to use them responsibly.  There are a couple of design features of the GrillGun that are created to help the user to operate it safely, but in the end, the safe operation of a GrillGun rests squarely on the user and not on the manufacturer for making such an incredibly cool and powerful tool.
10. The GrillGun is designed with a very lean gas to air mixture so the only way to get it to light consistently when you pull the trigger, is to have the gas on at its lowest possible setting.  This flow rate will almost always light the first time you pull the trigger, and it will almost never light with the fuel is turned up high or the handle squeeze trigger pulled, creating a high velocity flow of gas. I am not saying it will NEVER light with high gas flow, because there is gas in the presence of a spark and it may ignite anyway, but the likelihood of it lighting is significantly reduced.  This consideration was made in the design of the GrillGun to maximize the fuel burn, while still being able to safely light. You will want to just barely turn on the valve when lighting and then turn up the gas or pulse the flame with the squeeze handle, only when you want the intense heat, not before.
11. Never aim and light the GrillGun pointed at anything within a 5’ range that you don’t want to burn.
12. DO NOT TOUCH the fire bell after use as it most likely will be quite hot and will severely burn you until you allow it to cool down.
13. After using the GrillGun, do not lay it down in a manner where the fire bell is laying on or in direct contact with anything that is flammable or will be marked or melted by the hot metal fire bell.
14. Your GrillGun is shipped with a wire bottle stand.  The purpose of the stand is to allow you to set your GrillGun attached to a 1lb bottle, directly into the stand where it will stand upright while the fire bell cools down.  If you are using your grill GrillGun attached to an 8’ hose and propane tank, the wire stand can be used to lay the GrillGun’s fire bell upon it, keeping it off the table while it cools down.
15. A GrillGun or any other torch start fires and is dangerous if used carelessly, ignorantly or without regard to life, property or safety.
    If there is any possibility of the GrillGun getting into the wrong hands, you should separate the GrillGun from its fuel source and stored in a safe place when not in use.
