LOADING AND STARTING THE FIRE
COLD START LIGHTING
1. The air should be off. The engine should be running, but the PTO should be disen-
gaged.
2. The pit should be loaded with “Good Wood” as previously described.
3. Add accelerant like diesel fuel or something recommended by your local fire depart-
ment or forest service. A 40 foot pit will need about 10 gallons spread across the
pile.
4. For best results and quickest light up, start the fire from the bottom, because the fire
will spread up much better than it will spread down.
5. Use a propane torch (like a weed burner) or oil soaked rags on poles to light the
fire.
If you are using Diesel fuel as a starter, let the fire burn until you begin to see wisps of
white smoke replacing the wisps of black smoke from the Diesel fuel, or if you are us-
ing propane torches, wait until the fire has strengthened and flames are reaching the
top of the pit. Then engage the air fan at approximately 1,000 to 1,400 RPM. As the
fire burns stronger, increase the air (approximately 200 RPM every 15 minutes) up to
maximum.
Don’t increase the air too quickly, as you can “blow” the fire out. If you add air and the
smoke gets heavy, then reduce the RPM and let the fire “catch-up.” Once it clears up
you can slowly increase the air again.
Sometimes it is helpful to “fan” the fire during the start-up phase. You accomplish this
by increasing the RPM for 3 to 8 minutes, then decreasing them (i.e. 1,000 RPM up to
2,000 RPM and back down to 1,000 RPM). This sometimes helps to spread the fire
throughout the material. How much air to add and when to add it during startup will
vary with the type of materials being burned.
DANGER: Do not
use a highly flammable accelerants like gasoline
and solvents as they light explosively and may cause injury or death.
