Regency®E18 Gas Fireplace Insert 9
INSTALLATION
For minimum and maximum supply pressure
see the Specifications table.
1. If the appliance is to be installed into an
existing chimney system, thoroughly clean
the masonry fireplace that has been chosen
for the Regency®Gas Fireplace.
2. The appliance is provided with an opening
on the left hand side of the control
compartment for the gas line.
Note: During any pressure testing of the
gas supply piping system that exceeds test
pressures of 1/2 psig, this appliance and its
individual shut-off valve must be disconnected
from the piping system. If test pressures equal
to or less than 1/2 psig are used then this
appliance must be isolated from the piping
system by closing its individual manual shut-off
valve during the testing.
CAUTION: If the glass is removed for
servicing, it must be replaced prior to
operating the appliance. The glass must be
fixed in the closed position when operating.
GAS CONNECTION
Only persons licensed to work with gas piping
may make the necessary gas connections to
this appliance.
The gas connection is a 1/2" NPT accessible on
the left side of the unit. The gas line connection
may be made of rigid pipe, copper pipe or an
approved flex connector. (If you are using rigid
pipe, ensure that the valve can be removed
for servicing.) Since some municipalities have
additional local codes it is always best to consult
with your local authorities and the CAN/CGA
B149 installation code.
For USA installations follow local codes and/
or the current National Fuel Gas Code, ANSI
Z223.1.
When using copper or flex connectors use only
approved fittings.Always provide a union so that
gas lines can be easily disconnected for burner
or fan servicing. Flare nuts for copper lines and
flex connectors are usually considered to meet
this requirement.
Important: Always check for gas leaks
with a soap and water solution or gas
leak detector. Do not use open flame
for leak testing.
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. Read manometer.
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.

of wear and durability.
4.Determine the route for the electrical for
the circulation fan. The circulation fan is not
optional.
5. Determine the route for the gas supply.The valve
has a 1/2" Male Flare on the left side of the E18.
Some modification may need to be made to a
hard lined gas supply to connect to the E18.
6. Clean out the existing appliance of all dust and
debris.
7. Make the appropriate modifications to the existing
appliance specified in the "Existing Appliance
Modification" section of the manual. Make sure
when done there are no sharp edges exposed
to a person during operation of the unit.
8. Unpack the E18 from the box and disassemble.
9. Install the E18 into the existing unit as per
instructions.
10. Connect Gas Supply.
11. Connect Circulation Fan Power Cord.
12. Test Fire the E18 and check gas pressures
and confirm Circulation Fan begins operation
with 10 minutes of firing the unit.
13. Check draft hood for spillage as per instructions.
14. Install Trim Kit as per instructions.
MATERIALS REQUIRED
Electrical power supply is required for the circulation
fan A 120 Volt AC power cord is hooked up to the
fan. Plug the 3 wire cord into a suitable recepta-
cle. Do not cut the ground terminal off under any
circumstances. When connected with 120 volts,
the appliance must be electrically grounded in ac-
cordance with local codes, or in the absence of local
codes, with the current Canadian Electrical Code
CSA C22.1 (in Canada) or with the current National
Electrical Code ANSI/NFPA 70-1987 (in U.S.A.).
NOTE:This unit is equipped with a heat sensor

The Regency®Insert incorporates its own internal
draft hood, so no additional external draft hood is
required. Check periodically that the vent is unre-
stricted and an adequate draft is present when the
unit is in operation.
Before installing the vent system ensure that the
damper plate is locked into the open position and
secure to prevent the damper plate from falling
down and crushing the liner.
