U32-5 FPI Direct Vent Gas Insert

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.

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.

INSTALLATION

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.

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. See diagram 1.
Install the brick tabs. See diagram 2.

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.

GAS INSERT

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
fl 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

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.

Aeration Adjustment Wire

PULL= Open

PUSH = Close

Be careful not to damage thermal insula-

tion when sliding on vent connector plate.

This could cause blockage.
