From Wolf's site, about pilots: interesting, even if you factor in bias.

"Wolf Challenger ranges use one pilot light for each two burners (others use two). 3 standing pilot lights on a 6 burner Challenger range. (Other brands have 6).

A pilot burns about 673,000 btu / month.

It costs approximately $6.50 per pilot per month. Natural gas, LP gas approximately $10.00. Having 3 less pilot lights on a 6 burner range saves money monthly. Using the $6.50 figure is a monthly savings of $19.50 x 12 months = $234.00 per year x minimum average life of range at 7 years = $1,638.00 savings. "

"NOTE: Commercial ranges have open pilot lights and are not insulated, thus cannot be placed beside cabinets. Clearance to combustible material : 10" Sides, 2" Back. 0" Clearance to non-combustible material (most models)"

673,000 btu/mon is a lotta energy, relatively speaking.
