following:
INSTALLATION AND REPAIR
SHOULD BE DONE BY A QUALIFIED SERVICE PERSON. THE APPLIANCE SHOULD BE INSPECTED BEFORE USE AND AT LEAST
ANNUALLY BY A PROFESSIONAL
SERVICE PERSON. MORE FREQUENT CLEANING MAY BE REQUIRED DUE TO EXCESSIVE LINT
FROM CARPETING, BEDDING
MATERIAL, ETC. IT IS IMPERATIVE THAT CONTROL COMPARTMENTS, BURNERS AND CIRCULATING AIR PASSAGEWAYS OF
THE APPLIANCE BE KEPT CLEAN.
DUE TO HIGH TEMPERATURES,
THE APPLIANCE SHOULD BE LOCATED OUT OF TRAFFIC AND
AWAY FROM FURNITURE AND
DRAPERIES.

Before leaving this unit with the customer, the
installer must ensure that the appliance is firing
correctly and operation fully explained to customer.
This includes:
1) Clocking the appliance to ensure the cor-
rect firing rate (rate noted on label) after
burning appliance for 15 minutes.
2) If required, adjusting the primary air to
ensure that the flame does not carbon. First
allow the unit to burn for 15-20 min. to
stabilize.
CAUTION: Any alteration to the product that
causes sooting or carboning or that results in
damage is not the responsibility of the manufacturer.

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.
For both bottom and rear "outside air" the
Pedestal Cover Plate must be installed. Loosen
the 4 screws on the rear of the pedestal and
slide the cover plate over them. Slide the plate
to the left to center it and tighten down the 4
screws.
Outside Air Through
Pedestal Bottom
Once you have properly marked the position of
your unit as outlined in "General Information"
and "Clearances to Combustibles", cut a properly 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 outside
termination. Do not remove the knockout.
CLEARANCES TO
COMBUSTIBLES
The clearances listed below are MINIMUM distances. Measure the clearance to both the
appliance and the chimney connector. (The
farthest distance is correct if the two
clearances do not coincide.) For example, if
the appliance is set as indicated in one of the
figures but the connector is too close, move the
stove until the correct clearance 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.
This appliance may be installed only with the
clearances as shown in the situations pictured.
Do not combine clearances from one type of
installation with another in order to achieve
closer clearances.
Use the minimum clearances shown in the
diagrams below for installation with "B" vent.
Minimum ceiling height is 36" / 914 mm
from top of unit.
If further reduced clearances are needed, obtain requirements for construction of a protected wall from your local building authorities and
their allowable reductions of the listed clearances.
Rear View
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.

INSTALLATION
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 combustion air inlet to the burner. This
heater must be properly connected to a venting
system. This heater is equipped with a vent
safety shutoff system.
WARNING: Operation of this heater when
not connected to a properly installed and
maintained venting system or tampering
with the vent safety shutoff system can
result in carbon monoxide (CO) poisoning and possible death.
HIGH ELEV ATION
The U38 (with 40,000 BTU rating) is approved
in Canada for altitude 2000 ft. to 4500 ft. (CAN/
CGA-2.17-M91) with the orifice kit (Part # 591-
975). For Natural Gas installations above 4500
ft. follow current CAN/CGA-B149.1.
In U.S.A., for installations above 2000 ft. refer
to current ANSI Z223.1 Sc8-8.1.2a appendix F,
for resizing orifice.
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 using room air for
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 thermally actuated switch is
located within the draft 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 indicates a
drafting problem that must be identified and
rectified without delay - the thermally activated
switch must never be bypassed or disconnected as a hazardous or deadly condition can
result.
Venting Requirements
A four inch diameter vent is required. B-Vent,
Class A or Masonry with an approved liner are
all acceptable. For cosmetic or aesthetic purposes 6" outer vent can be used as long as an
approved inner vent is installed. Fasten but do
not penetrate the inner sleeve of the B-Vent
when tightening the screw.
Follow all venting manufacturer’s requirements
and local building codes. In cold climates, we
recommend the use of insulated B-vent, chase,
and liners. For altitudes above 2000 ft. we
recommend that a minimum flue height of 12 ft.
is used.
Vent Terminations
Installation into Existing
Woodstove Flue System
1) Clean existing Chimney system.
2) Run an approved 4" flex liner or "B" vent into
existing chimney.
Note:
See the chimney systems
manufacturer for detailed
installation instructions.
Regency U38 ULTIMATE Freestanding Gas Heater
Flue Mounting Bracket
Attach the flue mounting bracket with the
enclosed screw as shown in the diagram.

INSTALLATION
GAS CONNECTION
The gas line can be rigid pipe, or to make
installation easier, use a listed flexible connector if allowed by local codes. Copper may also
be used if approved by local codes.
The gas connection at the valve is 3/8" NPT. For
minimum and maximum supply pressure see

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 (14" w.c.).
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" (# 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.
4) Light the pilot and turn the valve to "ON"
position.
