GAS CONNECTION
3) Locate the center point where the vent will
pass through the chimney above the appli-
ance. 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 orifice supplied. For 2000' -
4500' use the optional field conversion kit (Part
#400-970 for Natural Gas units and Part #400-
971 for Propane units). In USA refer to ANSI
Z223.1-1988, Appendix F, for re-sizing orifice.
GAS CONNECTION WARNING:
Only persons licensed to work
with gas piping may make the
necessary gas connections to
this appliance.
1) If the appliance is to be installed into an
existing chimney system, thoroughly clean
the masonry or factory built fireplace.
2) The appliance is provided with an opening
on the left hand side of the control compart-
ment. A 1/2" gas supply pipe must be brought
near this inlet hole.
NOTE: Final gas connection should be after unit
is in place to avoid damage to line when
pushing the unit into position.
Diagram 1
WARNING: Operation of this appli-
ance when not connected to a prop-
erly installed and maintained venting
system or tampering with the blocked
vent shuto 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 ad-
equate 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.
GAS PRESSURE TEST
The unit is preset to give the correct gas input at the
specified 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 specified.

VENTING
This appliance is designed to attach to a 4" diam-
eter type B-Vent or listed gas fuel type vent liner
running the full length of the chimney. A minimum
flue 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.
DRAFT HOOD
CONNECTION
1) Attach the vent to the flue collar on the detach-
able draft hood. The flue collar of the appliance
will fit 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 fireplace, 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 firebox 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.)
Periodically check that the vent is unrestricted and
an adequate draft is present when the unit is in
operation. (See page 15 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.

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.
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 flue 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.
The thermally actuated safety switch will auto-
matically 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.
OPTIONAL
BRICK PANEL
1. Unwrap the brick pattern panels from the pro-
tective wrapping.
2. Remove the safety screen and glass front if it
is already installed.
3. Put the rear brick panel flat 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 five minutes, test that there is a “pull” on
the flue by placing a smoke match, cigarette
or similar device which gives off smoke, in
front of the spill tube. To 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.
GAS INSERT AERATION
SYSTEM
The aeration adjustment rod is attached to the air
shutter which is located just above the orifice 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 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.
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.
5) Slide brick panel under brick clips, tighten screws
securing clips to complete installation.
