*Overall length is
approximate and is dependent on length of actual burner
used. **Indicates Flanged Connection (150# RF).
***Add 4" to C and @" to D for 15 PSI Design. #Suffix Model Number by desired max operating pressure and
burner designation (e.g., MCH-12-15-50-PF-P = 15 BPH/50
psi trim/Power Flame Burner/Propane). Based on 150
PSI Section 1 Design.
