GAS Pipe Pressure Testing, Optional Brick Panel

INSTALLATION

GAS PIPE

PRESSURE TESTING

The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig. (3.45 kPa). Disconnect piping from valve at pressures over 1/2 psig.

The manifold pressure is controlled by a regulator built into the gas control, and should be checked at the pressure test point.

Note: To properly check gas pressure, both inlet and manifold pressures should be checked using the valve pressure ports on the valve.

1)Make sure the valve is in the "OFF" position.

2)Loosen the "IN" and/or "OUT" pressure tap(s), turning counterclockwise with a 1/8" wide ﬂat screwdriver.

3)Attach manometer to "IN" and/or "OUT" pressure tap(s) using a 5/16" ID hose.

4)Light the pilot and turn the valve to "ON" position.

5)The pressure check should be carried out with the unit burning and the setting should be within the limits speciﬁed on the safety label.

6)When ﬁnished reading manometer, turn off the gas valve, disconnect the hose and tighten the screw (clockwise) with a 1/8" ﬂat screwdriver. Note: Screw should be snug, but do not over tighten.

AERATION SYSTEM

The air shutter can be adjusted by moving the adjusting wire up or down. The wire is accessed through the bottom louver opening. Open the air shutter for a blue ﬂame or close for a yellower ﬂame. The burner aeration is factory set but may need adjusting due to either the local gas supply or altitude.

Minimum Air Shutter Opening:

1/8" Natural Gas

1/4" Propane

CAUTION: Carbon will be produced if air shutter is closed too much.

Note: Any damage due to carboning resulting from improperly setting the aeration controls is NOT covered under warranty.

Note: Aeration Adjustment should only be performed by an authorized FPI Installer at the time of installation or service.

OPTIONAL

BRICK PANEL

1)Unwrap the brick pattern panels from the protective wrapping.

2)Remove the glass front if it is already installed (see manual).

3)Put the rear brick panel ﬂat against the back of the unit.

4)Before installing the side brick panels, loosen the screws for the brick tabs enough so that you can slide the brick tabs on to the screws easily but that the tabs are secure. For the location of the side brick tab screws see diagram 1.

5)Remove the brick tabs and slide the side brick panels into position. Install the brick tabs. See diagrams 1 and 2.
