Pre-wired NK8046 Furnace, Forge & Sawdust Burner Kit
Utilizing the industry’s smallest microcontroller and associated voltage control circuitry, these modules with LED, consume less than 20 ma. This makes all of the NK8046 Kit well suited for low power applications such as battery operation but can easily be powered by any well-filtered and regulated DC power source with an output of 6-18VDC. The very small overall size of this module will allow it to be easily placed in and around any structure.
Connecting
the NK8046:
Installing the NK8046 is very straightforward. Because the module has circuitry on both sides, care must be taken to be sure that the components or wire solder points will not make contact with any metal object which could cause a short
This kit is pre-wired with
input power wires already connected. The red wire is for connection to +DC and
the black wire is for connection to –DC (ground). These wires are pre-tinned for
easy soldering to your power source.
Figure 1 below shows a close-up of the circuit and wiring connections. Point 3 &
4 are the outputs that connect to the attached LEDs with approximately 6 inches
of very tiny #38 insulated wire. Care must be taken not to kink these
wires during installation
Important note:
A low-wattage iron with a pointed tip should be used for connection of wires. Too much heat or solder can easily damage the wires.

The LED
included with this kit will provide sufficient brightness for a realistic
effect. The brightest light output will be seen from the front of the LED
surfaces, but this LED does also have relatively bright “side-shine” allowing
good viewing over a horizontal angle of up to 150 degrees. Plan the positioning
of the LED in your model to “point” them toward the middle of the viewing angle
for best effect.
We recommend mounting the LED from the back by
attaching adhesive to the wires near the back of the LED so adhesive is
not placed directly on the LED. It is also recommended that whatever
adhesive is used that it does not contain high aggressive solvents that
could attack the insulation on the wires. Walthers Goo is an example of
an “aggressive” solvent type adhesive. Elmers white Glue, CA (superglue)
and 2-part epoxies are very safe for this type of mounting and will not
damage wires or surfaces of your model in most cases.
We hope the
added realism it provides enhances your enjoyment of the hobby.
