The All Weather Electronic Ignition System (AWEIS) delivers an unprecedented performance that few can even come close to comparing! Whether you have a fire pit or a concrete fire bowl, your gas feature will continue to display an incredible flame set in even the most inclement weather with the help of an AWEIS.
The AWEIS (click on the picture at right to see a larger view) is considered the "heart" of an outdoor fire feature. It's main responsibilities are controlling the gas flow through the valve, initiating a pilot flame, and then causing the gas to ignite. It can be used to light one or multiple features, or even those hard to access fire bowls that have been positioned atop a tall pedestal, for example. The AWEIS does need to be connected to your home or pool electrical system, and can be easily operated with a switch or remote control.
Before we explain how to install an AWEIS, let's cover some general information and safety instructions:

LP Gas Installation Considerations:
Due to the fact that LP (propane) gas is different from natural gas there are slight differences in the installation procedures as follows:
PLEASE NOTE: a small amount of air will exist in the fuel supply lines. When first lighting your AWEIS, it will take a few seconds for air to purge from lines. Subsequent lighting of the AWEIS will not require such purging.
You need either one drain hole (1/2" in diameter) or multiple drain holes (each 1/4" in diameter). Without proper drainage, the bowl could fill up with water and damage the remote control module.
One dedicated 24 volt/75 VA transformer is required to power one AWEIS. We supply you with a 24 volt transformer and it is recommended that it is configured into your set-up in a remote location, away from the fire feature. It must be placed in an approved, weatherproof electrical junction box and installed in accordance with local codes. It is highly recommended that you have one dedicated wire run (2 wires) from each transformer to each fire feature.
Daisy-chaining of the wire can be accomplished if you use a minimum of 12 gauge wire to prevent voltage drop. When daisy-chaining the wire from the transformers to the first fire feature and to the remaining features, you must first wire the transformers in parallel with one another and to the wire leading to the fire features.
There are numerous electrical devices that can be used power your fire feature on and off. Wall switches and remote control devices that are used should be UL listed and approved for turning high voltage (110 volt electrical power) on and off. High voltage electrical power should be connected to the supplied 24 volt AC transformer by a qualified electrical installer only.
My pilot flames either won't light or fails to ignite consistently.
Problems with pilot flame ignition are most often caused by a low current situation. The hot surface igniter used in the AWEIS pilot burner requires a minimum of 1.2 amps at 24 volts to reach full operating temperature so that it can ignite the gas.
When the AWEIS is first turned on, the initial amp draw should be a minimum of 1.2 amps for the first 4 seconds. It will then increase to approximately 1.6 amps once the pilot valve is opened by the AWEIS. After ignition occurs, the hot surface igniter is turned off and the main gas valve is turned on. Amp readings after the main valve is turned on are approximately 0.8 to 1.0 amps.
What causes a low current situation?
This occurrence can be the result of one of two things:
My AWEIS turns off after a few minutes of operation.
This problem is caused by improper pilot burner positioning. In most cases, the pilot burner is positioned too high in relation to the fire ring. Remember: the top of the pilot burner cage should be no more than 1" above the fire ring.
My AWEIS turns off after an extended period of operation (greater than 15 minutes).
Generally, the AWEIS won't turn back on upon power cycling until 10 minutes later. Inside the AWEIS is a circuit board controller. It has a self-resetting thermal fuse which protects the system from overheating. If the AWEIS gets too hot, the thermal fuse will open and thus shut down the AWEIS. Once the fuse cools to a certain temperature (average time 10 minutes), it will reset itself and allow the AWEIS to be turned on again.
This situation occurs most frequently with fire features that use propane gas. For propane applications, a brass air mixer is added to the outlet of the AWEIS. The orifice inside the air mixer is sized to accommodate propane pressures between 7" to 10" WC (or 1/4 to 1/3 psi). When used with higher gas pressure, propane will be expelled out the 6 air holes in the mixer, causing a small fire directly above the valve box of the AWEIS. This small fire heats the valve box, which in turn causes the thermal fuse to open. In order to eliminate this problem, you can reduce the propane gas pressure by adjusting the second stage regulator until the pressure falls within proper WC range.
This problem can also be caused when extra large lava rock (greater than 4 inches in diameter) are used in the fire feature. Extra large lava rocks, due to their size, can absorb heat faster than they can radiates it. This is because it the core of each rock is incapable of release heat. Therefore, extra large pieces will get much hotter than smaller ones. Therefore, we recommend using lava rock no bigger than 4" in diameter.
