• a housing having an interior wall which surrounds an interior of said housing and
• a plurality of substantially parallel adjacent burner assemblies in said interior of said housing wherein each of said burner assemblies comprises:
• (a) a firebox comprising a longitudinally extending combustion chamber containment wall which is positioned within and different from said interior wall of said housing and which defines a combustion chamber therein, said combustion chamber containment wall having a substantially V-shaped cross-section, said combustion chamber containment wall having an upper discharge opening, and said combustion chamber containment wall further comprising:
• a longitudinally extending bottom spaced above and different from an interior bottom of said housing,
• a longitudinally extending left side, and
• a longitudinally extending right side,
• wherein, as viewed in said substantially V-shaped cross-section of said combustion chamber containment wall, said left and said right sides extend upwardly from said bottom of said combustion chamber containment wall to said upper discharge opening, said left and said right sides also diverge outwardly from, or proximately from, said bottom of said combustion chamber containment wall to, or proximately to, said upper discharge opening of said combustion chamber containment wall, and said left and said right sides have lower ends at said bottom of said combustion chamber containment wall which are located at a shared point or are not more than ½ inch apart and
