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.
GAS PRESSURE REQUIREMENTS
NOTE:
For altitudes above 2.000 feet some variations in air shutter settings may be required.

Manifold pressure must
be taken at the “OUTPUT PRESSURE" tap and inlet pressure at the "INLET PRESSURE" tap
with the burner
operating
by a qualified installer. Perform pressure tests prior to installing fascia material around this
fireplace.
