2) The appliance is provided with an opening
on the left hand side of the control com­partment. A 1/2" gas supply pipe must be
brought near this inlet hole. (See Diagram
3 on page 11).

3) Locate the center point where the vent will
pass through the chimney above the appli­ance. Move the appliance into the exact
location where it is to be installed. Ensure
that the Insert is level.

4) The installer must provide a valve with a
plugged tapping, accessible for test gauge
connection, immediately upstream of the
gas supply connection to the appliance.

HIGH ELEVATION

This unit is approved in Canada for altitude 0 to
2000 ft. with the orifi ce supplied. For 0' - 4500'
use the optional fi eld conversion kit (Part #400-
970 for Natural Gas units and Part #400-971 for
Propane units). In USA refer to ANSI Z223.1­1988, Appendix F, for re-sizing orifi ce.

Periodically check that the vent is unrestricted and
an adequate draft is present when the unit is in
operation. (See page 8 for spillage test.)
Before installing vent system ensure that the damper
plate is open and secure to prevent the damper plate
from falling down and crushing the liner.

DRAFT HOOD
CONNECTION

1) Attach the vent to the fl ue collar on the detach-

able draft hood. The fl ue collar of the appliance
will fi t inside a standard vent and may be fas-
tened directly to the vent by sheet metal screw.
Diagram 1.

2) Before pushing the appliance into position
inside the fi replace, align the draft hood with
the guides on the insert top and pull forward.
While pushing the unit back into place, keep
pulling the draft hood forward until the screw
hole in the spill tube aligns with the screw hole
in the draft hood locking tab on the underside
of fi rebox top. The screw is secured through the
draft hood locking tab into the front of the spill
tube. (If screw holes do not line up then draft
hood is not positioned correctly.

WARNING: Operation of this appli­ance when not connected to a prop­erly installed and maintained venting
system or tampering with the blocked
vent shutoff system can result in
carbon monoxide (CO) poisoning and
possible death.

Combustion and Ventilation Air

WARNING: This appliance needs
fresh air for safe operation and must
be installed with provisions for ad­equate combustion and ventilation
air available to the room in which it
is to be operating.

Follow CAN/CGA B149 (in Canada) or ANSI Z223.1
(in the USA) requirements, and any local codes or
regulations of the enforcing authority.

Air for combustion is drawn in through the front
of the unit, therefore, the front of the unit must be
kept clear of any obstructions.

VENTING

This appliance is designed to attach to a 4" diam­eter type B-Vent or listed gas fuel type vent liner
running the full length of the chimney. A minimum
fl ue height of 12 feet is recommended. B-Vent
must be supported by a vent support - supplied
by vent manufacturer. See chart on this page
for minimum distances from roof.

The Regency Insert incorporates its own internal
draft hood, so no additional external draft hood
is required.

NOTE: fi nal gas connection should be after

unit is in place to avoid damage to line
when pushing the unit into position.

GAS PRESSURE TEST

The unit is preset to give the correct gas input at the
specifi ed manifold pressures shown on the label.
The maximum gas manifold pressure is:
Natural Gas 3.5" w.c.
Propane 10" w.c.
The manifold pressure is controlled by a regulator
built into the gas control, and should be checked at
the pressure test point. The pressure check should
be carried out with the unit burning and

the setting should be within the limits specifi ed.

GAS INSERT AERATION

SYSTEM

The aeration adjustment rod is attached to the
air shutter which is located just above the orifi ce
bracket. The rod is used to adjust the aeration
on the main burner without having to take the
appliance apart.

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

Natural Gas: 3/8" (9.5mm) open
Propane: 3/8" (9.5mm) open

Note: Any damage due to carboning result-

ing 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.

Check for proper draft by placing a
match close to the draft check open­ing. This should be checked after the unit

Diagram 1

The smoke should be drawn into the spill tube. If
the smoke is still not drawn into the spill tube, turn
the unit off and check for the cause of the lack of
draft. If necessary, seek expert advice.

OPTIONAL

BRICK PANEL

1) Unwrap the brick pattern panels from the pro-

tective wrapping.

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

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

the unit.

TEST FOR FLUE

SPILLAGE

A " spillage" test must be made before the
installed unit is left with the customer. Follow
the procedure below:

1) Start all exhaust fans in the home and then

close all external doors and windows in the
house.

2) Light the unit and set controls to maximum.
Turn fan off.

3) After fi ve minutes, test that there is a “pull” on
the fl ue by placing a smoke match, cigarette or
similar device which gives off smoke, in front
of the spill tube. T o ensure a valid test, place a
scrap piece of sheet metal (or other noncom­bustible material) between the spill tube and
the upper louver, this will prevent the natural
convection of the unit from interfering with the
test. See diagram 1.

For wind turbulent sites, a wind cap may remedy
the problem.

Note: The thermally activated safety switch will
sense the change in temperature and shut down
the gas valve in the event of a severe downdraft
or a blocked or disconnected vent. The switch
acts as a safety shut-off to prevent a build-up
of carbon monoxide. If the fl ue is blocked or
has no "draw", the switch will automatically
shut off the supply of gas within 5 - 10 minutes.
Tampering with the switch can result in carbon
monoxide (CO) poisoning and possible death.

If the heater turns off because of lack of draft
during the spillage test, check for the cause
and if necessary, seek expert advice.

4) Before installing the side brick panels, loosen

the screws for the brick tabs enough so that you
can slide the brick clips on to the screws easily
but that the tabs are secure. For the location
of the side brick tab screws see Diagram 2.

Diagram 2

5) Slide brick panel under brick clips, tighten screws
securing clips to complete installation.

The thermally actuated safety switch will auto­matically reset after it has cooled off. The switch
will continue to cycle until the draft problem is
corrected. DO NOT BYPASS OR DISCONNECT
THIS SWITCH.

FIRST FIRE

The fi rst fi re in your stove is part of the
paint curing process. To ensure that the
paint is properly cured, it is recommended
that you burn your fi replace for at least
four (4) hours the fi rst time you use it
with the fan on. When fi rst operated,
the unit will release an odour caused by
the curing of the paint, the burning off of
any oils remaining from manufacturing.
Smoke detectors in the house may go
off at this time. Open a few windows to
ventilate the room for a couple of hours.

The glass panel may require cleaning
after the unit has cooled down.

DO NOT ATTEMPT TO CLEAN THE
GLASS WHILE IT IS HOT.

Note: When the glass is cold and

the appliance is lit, it may
cause condensation and fog
the glass. This condensation
is normal and will disappear
in a few minutes as the glass
heats up.

DO NOT BURN THE APPLI­ANCE WITHOUT THE GLASS
FRONT IN PLACE.

AUTOMATIC

CONVECTION

FAN OPERATION

The fan operates automatically, turn the knob
on the side of the faceplate to adjust to the
desired speed. The fan will turn on as the stove
comes up to operating temperature. After the
unit has been turned off and the unit cooled to
below a useful heat output range the fan will
shut off automatically.

NORMAL OPERATING SOUNDS OF

GAS APPLIANCES

It is possible that you will hear some sounds
from your gas appliance. This is perfectly
normal due to the fact that there are various
gauges and types of steel used within your
appliance. Listed below are some examples.
All are normal operating sounds and should
not be considered as defects in your appliance.

Blower:

FPI gas appliances use high tech blowers to
push heated air farther into the room. It is not
unusual for the fan to make a "whirring" sound

a

when ON. This sound will increase or decrease
in volume depending on the speed setting of
your fan speed control.

Burner Tray:

The burner tray is positioned directly under the
burner tube(s) and logs and is made of a differ­ent gauge material from the rest of the fi rebox
and body. Therefore, the varying thicknesses of
steel will expand and contract at slightly different
rates which can cause "ticking" and "cracking"
sounds. Y ou should also be aware that as there

Regency U31-3 Gas Fireplace Insert

2525

MAINTENANCE

are temperature changes within the unit these
sounds will likely re-occur. Again, this is normal
for steel fi reboxes.

Blower Thermodisc:

When this thermally activated switch turns ON
it will create a small "clicking" sound. This is the
switch contacts closing and is normal.

Pilot Flame:
While the pilot fl ame is on it can make a very
slight "whisper" sound.

Gas Control Valve:
As the gas control valve turns ON and OFF, a
dull clicking sound may be audible, this is normal
operation of a gas regulator or valve.

Unit Body/Firebox:
Different types and thicknesses of steel will
expand and contract at different rates resulting
in some "cracking" and "ticking" sounds will be
heard throughout the cycling process.

MAINTENANCE

INSTRUCTIONS

1) Always turn the gas valve to off before

cleaning. For relighting, refer to lighting
instructions. Keep the burner and control
compartment clean by brushing and vacu­uming at least once a year.

When cleaning the logs, use a clean soft

paint brush as the logs are fragile and easily
damaged.

2) Clean (never when unit is hot) appliance,
door and louvers with a damp cloth. Never
use an abrasive cleaner. The gold louvers
(and optional gold door) may be scratched
if abrasives are used to clean them.

The heater is fi nished in a heat resistant

paint and should only be refi nished with
heat resistant paint (not with wall paint).
FPI uses StoveBrite Paint - Metallic Black
#6309.

3) Make a periodic check of burner for proper
position and condition. Visually check the
fl ame of the burner periodically, making sure
the fl ames are steady; not lifting or fl oating.
If there is a problem, call a qualifi ed service
person.

4) The appliance and venting system must be
inspected before use, and at least annually,
by a qualifi ed fi eld service person, to ensure
that the fl ow of combustion and ventilation
air is not obstructed.

During the annual service call, the burners

should be removed from the burner tray
and cleaned. Replace the embers but do
not block the pilot.

5) Keep the area near the appliance clear and
free from combustible materials, gasoline
and other fl ammable vapours and liquids.

WARNING: CHILDREN AND
ADULTS SHOULD BE ALERTED
TO THE HAZARDS OF HIGH
SURFACE TEMPERATURE AND
SHOULD STAY AWAY TO AVOID
BURNS OR CLOTHING IGNITION.
YOUNG CHILDREN SHOULD BE
CAREFULL Y SUPERVISED WHEN
THEY ARE IN THE SAME ROOM
AS THE APPLIANCE.

CAUTION: ANY SAFETY SCREEN
OR GUARD REMOVED FOR SERV­ICING AN APPLIANCE MUST BE
REPLACED PRIOR TO OPERAT­ING THE APPLIANCE.

CLOTHING OR OTHER FLAM­MABLE MA TERIAL SHOULD NOT
BE PLACED ON OR NEAR THE
APPLIANCE.

6) Each time the appliance is lit, it may cause

condensation and fog the glass. This
condensation and fog is normal and will
disappear in a few minutes as the glass
heats up.

Never operate the appliance without the

glass properly secured in place, with
broken glass or with the door open.

7) Verify proper operation after servicing.

8) Periodically check the pilot fl ames, there

should be three strong blue fl ames approx.
3/4" long - 1 fl ame to the front burner, and
1 to the thermopile and one to the left. See
diagrams below.

Correct fl ame pattern has four strong blue
fl ames: 1 fl owing around the thermopile and

thermocouple and 1 reaching towards the
rear burner and 1 toward the front(it does
not have to be touching the burner).

Top View of pilot fl ame

Incorrect fl ame pattern will have small, prob-
ably yellow fl ames, not coming into proper
contact with the rear burner or thermopile.

Top View of pilot fl ame

If you have an incorrect fl ame pattern,

contact your FPI dealer for further instruc­tions.

GOLD-PLATED TRIM

The 24 carat gold plated fi nish on the trim
requires little maintenance, and need only be
cleaned with a damp cloth. DO NOT use abrasive
materials or chemical cleaners, as they may
harm the fi nish and void the warranty.

Clean any fi ngerprints off before turning the

unit on. If the top louvers start to discolour,
check the door gasket seal and replace if
necessary.

LOG REPLACEMENT

The unit should never be used with broken logs.
Turn off the gas valve and allow the unit to cool
before opening door to carefully remove the
logs. The pilot light generates enough heat to
burn someone. If for any reason a log should
need replacement, you must use the proper
replacement log. The position of these logs
must be as shown in the diagram under Log
Installation.

NOTE: Improper positioning of logs may

create carbon build-up and will alter
the unit’s performance which is not
covered under warranty.

GLASS GASKET

If the glass gasket requires replacement use
7/8" fl at glass gasket (Part # 936-243) for the
Bay Front and for the Flush Front.

very important- try to move the fan back and forth,
there should be no noise, if there is check that the
