INSTALLATION

Be careful not to damage thermal insula- tion when sliding on vent connector plate.

This could cause blockage.

9)Connect the 2nd liner to the exhaust collar marked with an "E", seal connection with high temperature silicone. Secure with gear clamp.

NOTES:

1)Final gas connection should be made after unit is in place to avoid damage to line when pushing the unit into position.

2)Mill-pac may be used instead of high temperature silicone and screws may be used instead of gear clamps at connections of liner to inlet and vent collars.

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 fl at 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 specifi ed on the safety label.

6)When fi nished reading manometer, turn off the gas valve, disconnect the hose and tighten the screw (clockwise) with a 1/8" fl at 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 fl ame or close for a yellower

ame. The burner aeration is factory set but may need adjusting due to either the local gas supply or altitude.

Minimum Air Shutter Opening:

3/16" Natural Gas

1/4" Propane

OPTIONAL

BRICK PANEL

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

2)Remove the glass front if it is already installed, see "Standard Flush Door" section.

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

4)Beforeinstallingthesidebrickpanels,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.

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.

Themanifoldpressureiscontrolledbyaregulator 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.

Aeration Adjustment Wire

PULL= Open

PUSH = Close

CAUTION:Carbonwillbe produced if air shutter is closed too much.

Note:anydamageduetocarboningresulting fromimproperlysettingtheaerationcontrols is NOT covered under warranty.

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