Outside Air Through
Rear of Pedestal
Remove the blanking plate from the rear of the
pedestal cover plate and bend the two tabs
out 90 degrees. Pipe fresh air into the pedestal
area by using duct pipe with a mesh grill at the
outside termination.Attach the pipe to the tabs
with screws.
OPTIONAL
OUTSIDE AIR
Outside air for combustion can be brought in
either through the bottom of the pedestal or
through the rear plate of the pedestal.
Forbothbottomand rear "outside air" the Ped-

Onceyouhaveproperly markedthepositionof
your unit as outlined in "General Information"
and "Clearances to Combustibles", cut a prop-
erly sized hole though the floor directly under
your pedestal base to the outside. Pipe fresh
air into the pedestal area by using appropriate
metallic duct pipe with a mesh grill at the out-
side termination. Do not remove the knockout.
CLEARANCES TO
COMBUSTIBLES
The clearances listed below are MINIMUM dis-
tances. Measure the clearance to both the appli-
ance and the chimney connector. (The farthest
distanceis correct if thetwo clearances donot
coincide.) For example, if the appliance is set as
indicated in one of the figures but the connector is
tooclose,movethestoveuntilthecorrectclearance
to the connector is obtained.
This unit can be installed on a solid combustible
surface like a wood floor. This unit can also be
installed directly on carpeting or vinyl when the
bottom pedestal cover plate (provided with unit)
is installed.

INSTALLATION
VENTING
This heater is a vented appliance and must be
connected to a chimney/flue in accordance with
the installation codes.
Note: The rear pedestal cover plate is only
required when outside air is being
used.If usingroom airfor combustion,
remove this plate from the back of the
pedestal.
For your safety this heater is equipped with a vent
safety switch designed to sense incorrect venting
and react by shutting down the gas supply. This
thermallyactuated switch is located withinthedraft
hood and will detect either a blocked chimney or
backdraft condition where the chimney flow has
reversed. If this switch shuts the unit down, it in-
dicates a drafting problem that must be identified
andrectifiedwithout delay - the thermally activated
switchmust neverbebypassedordisconnectedas
a hazardous or deadly condition can result.
Venting Requirements
Afourinchdiameter ventisrequired. B-Vent,Class
Aor Masonry with an approved liner are all accept-
able. For cosmetic or aesthetic purposes 6" outer
ventcanbeusedaslongasanapprovedinnervent

sleeve of the B-Vent when tightening the screw.
Followallventingmanufacturer’srequirementsand
local building codes. In cold climates, we recom-
mendtheuseofinsulatedB-vent,chase,andliners.
For altitudes above 2000 ft. we recommend that a
minimum flue height of 12 ft. is used.
Flue Mounting Bracket
Attach the flue mounting bracket with the enclosed
screw as shown in the diagram.
DRAFT HOOD
This heater has a draft hood built in. It must not
be altered, obstructed, or blocked in any way, and
the unit must be installed so that the draft hood
is in the same atmospheric pressure zone as the
combustionair inlet to the burner.This heater must
be properly connected to a venting system. This
heaterisequippedwithaventsafetyshutoffsystem.
WARNING: Operation of this heater when not

shutoff system can result in carbon monoxide
(CO) poisoning and possible death.
HIGH ELEVATION
The U38-1 (with 40,000 BTU rating) is approved
in Canada for altitude 2000 ft. to 4500 ft. (CAN/
CGA-2.17-M91)withtheorificekit(Part#591-975).
For Natural Gas installations above 4500 ft. follow

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). Disconnectpipingfromvalveatpressures
over 1/2 psig (14" w.c.).
Themanifoldpressureiscontrolledbyaregulator
builtintothegascontrol,andshouldbechecked
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" posi-
tion.
2) Loosen the "IN" (# 7) and/or "OUT" (# 6)
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.
GAS CONNECTION

The thermally activated safety switch must
be manually reset before first startup.
Note: If the flue is blocked or has a strong
reverse flow, the thermally actuated safety
switch mounted in the draft hood will auto-
maticallyshutoffthegassupplywithinabout
10 minutes. If the heater turns off because
ofthis during thespillage test, checkfor the
cause of the lack of draft.
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 any
other gas appliances. Then close all doors
and windows.
2) Light the unit and set controls to maxi-
mum.
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, on the edge of the draft hood. See
diagrams.
LOUVER
INSTALLATION
1) Attach the top & bottom louvers to the side
stove panel using 2 screws per side.

INSTALLATION
(packaged separately)
1) Open the two side panels.
4) Thelatchesshouldalreadybeattheproper

to close, you may want to adjust them by
loosening the latch catch. See diagram 3.

5) Removetheblueplasticprotectivecoating
from the glass.
6) Test the seal around the door by placing
a piece of paper between the unit and the
door,closethedoorandtrytopullthepaper
out. If it slips out easily, then the door is
not properly sealed. Tighten or loosen the
latch. See diagram 3.
2) Slide the door
ontothetwohinge
pins making sure
the two pieces
areflushtogether.
See diagram 1.
3) Close the door.
The latch plate
must be cen-
tered around the
alignment pin. See
diagram 2. If the latch
plateinterfereswiththe
corner of the stove you
may want to angle the
plateslightlysothedoor
closes easier.
Note: The door latch may require adjust-
ment as the door gasket material
compresses after a few fires and
after glass replacement. Turn the
latch catch inward or outward to
loosen or tighten.
The smoke should be drawn into the draft
hood. If the smoke is not drawn into the draft
hood, turn the unit off and check for the cause
of lack of draft.

FINAL CHECK
Before leaving this unit with the customer, the
installer must ensure that the appliance is firing
correctly. This includes:
1) Clocking the appliance to ensure the correct
firing rate (rate noted on label) at 15 minutes.
2) If required, adjusting the primary air to ensure
that the flame does not carbon. First allow the
unit to burn for 15 min. to stabilize.
3) Check for proper draft.
CAUTION
Any alteration to the product that
causes sooting or carboning that
results in damage to the exterior
facia is not the responsibility of the
manufacturer.
1) Choose a convenient location on the wall
to install the receiver and the receptacle
box (protection from extreme heat is very
important). Run wires from the fireplace to
that location, use Thermostat Wire Table.
2) Connectthewiresasperthewiringdiagram
above.
CAUTION
Do not connect the millivolt re-
mote control wires to
the 120V wires.
3) Install3AAAalkalinebatteriesintransmitter
and 4 AA alkaline batteries in the receiver.
Install the receiver and its cover in the wall.
Switch the remote receiver to "remote"
mode. The remote control is now ready for
operation.
OPTIONAL
WALL THERMOSTAT
A wall thermostat may be installed if desired.
Connect the wires as per the wiring diagrams.
Note that the wires are connected to the "TH"
on the gas valve. Use table below to determine
the maximum wire length:
Note:Preferableifthethermostatisinstalled

Regency®offers an optional programmable
thermostat but any 250-750 millivolt rated non-
anticipator type thermostat that is CSA, ULC or
UL approved may be used.
