Minimum Flow Capacity
NOTICE
The minimum flow capacity values in the charts are at 0.5" w.c. pressure drop
(inlet pressure minus outlet pressure). If your gas system has more available
pressure drop then a general rule of thumb approximate calculation is as
follows:
Minimum Flow Capacity @ your pressure drop = Square Root
(your pressure drop/0.5) x value from chart
Example: What is the approximate minimum flow capacity
(natural gas) of the Dormont 30 Series x 24" @
1" wc pressure drop?
Answer: Square Root (1/0.5) x 150,000 = 212,132 BTU/hr
WARNING
All installations must completely comply with all Dormont
manufacturing company warnings and instructions, national,
state and local codes and all applicable ANSI standards.
