CODES
Adhere to all local codes or in their absence the
latest edition of The National Fuel Gas Code
ANSI Z223.1 or NFPA54 which can be obtained
from The American National Standards Institute, Inc. (1430 Broadway, New York, NY,
10018) or National Fire Protection Association,
Inc. (Batterymarch Park, Quincy, MA, 02269).
State or local codes may only allow operation of
this appliance (manual version only) in a vented
configuration. Check your state or local codes.
Seller of unvented propane or natural gasfired supplemental room heaters shall provide to each purchaser a copy of 527 CMR 30
upon sale of the unit.
Serene Heat Gas Log appliances are certified by
OMNI-Test Laboratories to ANSI Z21.11.2 unvented room heaters standard. These gas log
appliances may be used as a space heat source
for a room in conjunction with an approved
unvented firebox.
Additionally, these units are design certified
by OMNI-Test Laboratories to ANSI 21.60 as a
vented gas log set.
As such, these units may be used as a vented
gas log set in any wood-burning fireplace that
has been properly constructed to code, and in
the case of factory built fireplaces, installed in
compliance with manufacturers listing and
installation instruction.
Use of the log sets covered by this manual in
a properly vented wood-burning fireplace which
has had the damper blocked open as detailed
below, preclude consideration of the combustion and ventilation air and clearance to combustible restrictions discussed herein.
When local codes require the damper to be
fixed open, a damper stop must be installed to
prevent full closure of the fireplace damper
and provide a minimum 29 square inch flue
opening at all times.
If damper clamp is not available, the damper
may be fixed open in the following manner.
Drill a hole in the end of the damper. Screw in
a bolt of sufficient size and adjust to provide the
minimum 29 square inches of flue opening.
COMBUSTION AND VENTILATION AIR
These heaters shall not be installed in a confined space. The heater may be located in
unusually tight construction provided the
space is unconfined, or if confined, is provided with two permanent openings communicating directly with an additional room(s)
of sufficient volume so that the combined
volume of all connected spaces meets the
criteria for an unconfined space, (National
Fuel Gas Code ANSI Z223.1 (latest edition),
Section 5.3). Generally 50 ft
input of all operating appliances in the space.
The National Fuel Gas Code defines a confined space as a space whose volume is less
than 50 ft
3
per 1,000 BTU/Hr (4.8 m3 per kw)
of the aggregate input rating of all appliances
installed in that space and an unconfined
space as a space whose volume is not less
than 50 ft3 per 1,000 BTU/Hr (4.8 m3 per kw)
of the aggregate input rating of all appliances
installed in that space.
NOTE: DIAGRAMS & ILLUSTRATION NOT TO SCALE.
3
per 1,000 BTU
Rooms communicating directly with the space
in which the appliances are installed, through
openings not furnished with doors, are considered a part of the unconfined space.
Unusually tight construction is defined as construction where:
a. wall and ceilings exposed to the outside
atmosphere have a continuous water vapor
retarder with a rating or one perm or less with
openings gasketed or sealed, and
b. weather stripping has been added on operable windows and doors, and
c. caulking or sealants are applied to areas
such as joints around window and door frames,
between sole plates and floors, between wallceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines,
and at other openings.
Use the following equations to determine if
you have a confined or unconfined space.
1. Determine the volume of space — ft
Length x Width x Height = _____ ft
3
.
3
(Include adjoining rooms with doorless passageways or ventilation grills between rooms.)
Example: 24' (L) x 16' (W) x 8' (H) = 3072 ft
2. Divide the volume of space by 50 ft3 to
determine the maximum BTU/Hr the space
can support.
______ (volume of space – ft3)/ 50 ft3 =
(Maximum BTU/Hr the space can support)
Example: 3072 ft3 / 50 ft3 = 61.44
or 61,440 BTU/Hr the space can support.
3. Add the BTU/Hr of all the fuel burning appli-
ances in the space.
Vent-Free Heater _______ BTU/Hr
Gas Appliance #1* _______ BTU/Hr
Gas Appliance #2 + _______ BTU/Hr
Total = _______ BTU/Hr
Example:
Vent-Free Heater 36,000 BTU/Hr
Gas Appliance #1 35,000 BTU/Hr
(water heater)
Total = 71,000 BTU/Hr
* Do not include Direct-Vent Gas Appliances.
Direct-Vent is sealed combustion and draws
combustion air from the outdoors.

can support with the actual amount of BTU/
Hr used.
_________ BTU/Hr
(max. the space can support)
_________ BTU/Hr
(actual amount of BTU/Hr used)
CAUTION: APPLIANCES CREATE WARM AIR
CURRENTS. THESE CURRENTS MOVE HEAT
TO WALL SURFACES NEXT TO APPLIANCE.
INSTALLING APPLIANCE NEXT TO VINYL OR
CLOTH WALL COVERINGS OR OPERATING
APPLIANCE WHERE IMPURITIES IN THE AIR
(SUCH AS TOBACCO SMOKE) EXISTS, MAY
DISCOLOR WALLS.
Follow these instructions carefully to ensure
safe installation. Failure to follow these requirements may create a fire hazard.
Step 1. Sidewall Clearances: The sides of the
fireplace opening must be at least 16" from any
combustible side wall (
Figure 1
).
Example:
61,440 BTU/Hr
(max. the space can support)
71,000 BTU/Hr
(actual amount of BTU/Hr used)
The space in the above example is a confined
space because the actual BTU/Hr used is more
than the maximum BTU/Hr the space can support. You must provide additional fresh air.
Your options are:
a. Rework equations adding the space of ad-
joining room(s). If the extra volume provides
an unconfined space, then remove door or
add ventilation grills between rooms. Refer
to National Fuel Gas Code, ANSI Z223.1,
Section 5.3.
b.Vent room directly to the outdoors. Refer to
National Fuel Gas Code, ANSI Z223.1, Section 5.3.
c. Install a lower BTU/Hr appliance, such as a
24,000 BTU/Hr, to make the area an unconfined space.
If the actual BTU/Hr used is less than the
maximum BTU/Hr the space can support, then
the space is an unconfined space. You will need
no additional fresh air ventilation for an unconfined space.
Note: Illustrations shown in this manual reflect
“typical” installations with nominal dimensions
and are for reference only. Actual installations
may vary due to individual design preferences.
However, always maintain minimum clearances
to combustible materials and do not violate any
specific installation requirements. Refer to Figures 1 through 7 for clearances.
Note: The following steps represent the normal
sequence of installation. Each installation is
unique, however, and might require a different
sequence.
• Turn off gas supply to the fireplace or firebox.

INSTALLATION
WARNING: DO NOT ALLOW FANS TO
BLOW DIRECTLY INTO THE FIREPLACE.
AVOID ANY DRAFTS THAT ALTER
BURNER FLAME PATTERNS.
WARNING: DO NOT USE A BLOWER INSERT, HEAT EXCHANGER INSERT OR
OTHER ACCESSORY NOT APPROVED
FOR USE WITH THIS APPLIANCE.
This appliance must not be operated without a
fireplace screen installed. Fireplace screens
must not impair the free flow of combustion air
to the appliance.
Do not burn solid fuels in any fireplace equipped
with this Dual-Listed gas appliance.
WARNING: INSTALLED DECORATIVE
GLASS DOOR ENCLOSURES MUST BE
FULLY OPENED WHEN OPERATING THIS
DUAL-LISTED GAS APPLIANCE.
Any outside air ducts and/or ash dumps that
are part of the original solid fuel burning fireplace system must be fully closed and sealed at
the time of installation of this Dual-Listed gas
appliance.
WARNING: SPECIAL CARE IS REQUIRED
IF YOU ARE INSTALLING THE UNIT INTO
A SUNKEN FIREPLACE. YOU MUST RAISE
THE FIREPLACE FLOOR TO ALLOW ACCESS TO GAS LOG CONTROLS. THIS WILL
INSURE ADEQUATE AIR FLOW AND
GUARD AGAINST SOOTING. RAISE THE
FIREPLACE FLOOR USING NONCOMBUSTIBLE MATERIALS.
A qualified gas appliance installer must install
this appliance.
Step 2. Connecting Gas Line – A qualified gas
appliance installer must connect the dual-listed
gas appliance to the gas supply.
Consult all local codes.
Route gas line using techniques and materials
prescribed by local and/or national codes. Only
use pipe of ¹⁄₂" or greater diameter to allow full
gas volume to the gas fireplace. Undue pressure loss will occur if the pipe is too small.
An ANSI approved manual shut-off valve and
union must be installed upstream of the appliance
within the fireplace cavity when rigid pipe is used.
IMPORTANT: HOLD APPLIANCE REGULATOR
WITH A WRENCH TO PREVENT MOVEMENT
WHEN CONNECTING TO INLET PIPING
An external regulator must be used on all
propane (L.P.G.) appliances, in addition to the
regulator fitted to the appliance, to reduce the
supply tank pressure to 13" w.c. (maximum).
WARNING: CONNECTING DIRECTLY TO
AN UNREGULATED PROPANE TANK MAY
CAUSE AN EXPLOSION.
The appliance gas inlet connection is ³⁄₈" NPT
at the regulator/valve, located on the left side
facing the appliance. If a right side connection
is required, the connection pipe may be piped
under the rear of the appliance to end at the left
hand side for connection to the inlet.
When tightening up the joint to the regulator
hold the regulator securely with a wrench to
prevent the regulator from moving.
Checking Gas Connections
Secure all joints tightly using appropriate
tools and sealing compounds (ensure propane resistant compounds are used in
propane applications).
B. Brush all joints and connections with the
gas leak test solution to check for leaks. If
bubbles are formed, or gas odor is detected,
turn the gas control knob to the “OFF” position. Either tighten or refasten the leaking
connection and retest as described above.
C. When the gas lines are tested and leak free,
be sure to rinse off the leak testing solution.
D. When the gas lines are tested and leak free,
observe the individual tongues of flame on the
burner. Make sure all ports are open and
producing flame evenly across the burner. If
any ports are blocked, or partially blocked,
clean out the ports.
Gas Pressure Check
The appliance regulator controls the burner
pressure which should be checked at the pressure test point (¹⁄₈" NPT plugged tap) located on
the manual control valve body (on Manual
models) or on the control valve itself (on Millivolt models), identified OUT for the manifold
side and IN for inlet pressure (
Ensure operating pressures are within the limits specified in the technical chart on page 10.
The pressure should be checked with the gas
appliance burning and the control set to high.
Manual Valve
Manifold Pressure
Millivolt Valve
see Figure 8
).
Check gas type: The gas supply must be the
same as stated on the appliance’s rating
plate. If the gas supply is different, DO NOT
INSTALL the appliance. Contact your dealer
for the correct model.
Step 1. Placement of Appliance – Center the
appliance in the fireplace or firebox. Make
certain the grate front feet sit inside the front
edge of the fireplace or firebox, and that there
is adequate clearance around the appliance for
access and operation.
6
Turn on gas supply and test for gas leaks,
using a gas leak test solution (also referred to
as bubble leak solution).
Note: Using a soapy water solution (50% dish
soap, 50% water) is an effective leak test
solution but it is not recommended, because
the soap residue that is left on the pipes/
fittings can result in corrosion over time.
Never use an open flame to check for leaks.
A. Light the appliance (refer to the lighting
instructions label in the control compartment
or in the Homeowner's Care and Operation
Instructions).
