An electric circuit consisting of two pieces of dissimilar metals joined together at one end (hot junction). When the hot junction is heated, the thermocouple produces DC voltage across the other end. Heat from the pilot will generate 24mv to 30mv.  This in turn holds the electomagnetic coil open, allowing gas to enter the valve body and hold a pilot flame.  It also acts as a safety device that will shut off the gas supply to the main burner and pilot when no flame (heat) is sensed.

A thermodisk is a temperature sensing device. When heat is applied to the disk, a bi-metal plate will bend. This allows the electric current to activate the blower motor and ensures continuity.

A number of thermocouples connected in series to produce a higher voltage than a single thermocouple. When heat is applied to the thermopile, an electric current is generated in the range of 450mv to 750mv. When the valve coil reaches the minimum required millivolts, the valve will open and gas will flow to the mainburner and ignite.

A wall mounted device that regulates the heat in the home by controlling the operation and heat of your gas fire.

Zero clearance gas fireplaces are used in installations where there is no existing fireplace (new construction or renovation).  These are factory-built metal fireplaces using a multi-layer construction (an inner & outer shell) which can safely be placed in direct contact (zero clearance) with combustible floors and walls.
