Fireplace

Pressure requirements for Heat-N-Glo gas appliances are shown in the table below.

Pressure	Natural Gas	Propane
Minimum	5.0 inches	11.0 inches
Inlet Pressure	w.c.	w.c.
Maximum Inlet	14.0 inches	14.0 inches
Gas Pressure	w.c.	w.c.
Manifold	3.5 inches	10.0 inches
Pressure	w.c.	w.c.

A one-eighth (1/8) inch (3 mm) N.P.T. plugged tapping is provided on the outlet side of the gas control for a test gauge connection to measure the manifold pressure. To measure inlet pressure, provisions must be made to attach a test gauge to a one-eighth (1/8) inch (3 mm) N.P.T. plugged tapping immediately upstream of the gas supply connection to the fireplace. On some models there may be a tap for the manifold and inlet pressure on the face of the valve. Use a small flat blade screwdriver to open the needle valve tap. Position a rubber hose over the tap to obtain the pressure reading.

The fireplace and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of the system at test pressures in excess of one-half (1/2) psig (3.5 kPa).

The fireplace must be isolated from the gas supply piping system by closing its individual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than one-half (1/2) psig (3.5 kPa).

NOTE: Electrical wiring must be installed by a licensed electrician.

DISCONNECT REMOTE CONTROLS IF YOU ARE ABSENT FOR EXTENDED TIME PERIODS. THIS WILL PREVENT ACCIDENTAL FIREPLACE OPERATION.
