Burner Ignition Sequence1.) Pilot Ignites Main Burner Next

to Pilot Assembly. 2.) Remaining Burners and Carry

Over Bar Fill with Gas, First Burner Ignites Carry Over Bar.

3.) The Combination of the Ignited Carry Over Bar and flame crosses over between Burners to Ignite the remaining Burners.

Heat Exchanger/Inshot Rack on Commercial Unit

Construction of inshot rack securely holds burners on their centerline so they do not impinge on tube interior surface, a potential cause of premature heat exchanger failure

Attaches directly to the bottom of the tubular heat exchanger assembly
