The Igniter is a machine added by the RedPower2 Mod that creates a flame in the front of the block when powered by a redstone source, and extinguishes the flame when in an unpowered state.
The igniter block just like most other blocks faces towards the player upon placing it.
The flame produced by the igniter is treated normally, and as such it can be extinguished by other sources. It can also be used to ignite Nether Portals.
Usage In Automated Animal Farms
This machine can be a very useful addition to the creation of slaughter houses in an effort to create a type of automatic animal killer and meat cooker; which obviously offers more 'steak' restoration alongside the prevention of 'chicken poisoning'.
