regulator is of adequate capacity to service the gas appliances (such as dryer, furnace, etc.). If this regulator's capacity is
not sufficient to add the Gas Fireplace, an additional "inches to inches" regulator must be installed for the Fireplace.
EXCEPTION: Some codes allow 2-PSI (1.4KPA) supplies to enter the residence, in which case "pounds to inches" regula-
tors are used.
The following table provides information on correct gas pressure requirements. Be sure your gas supplier or plumber
carefully follows this table.
