INTRODUCTION
These Gas Log Appliances incorporate unitized ceramic fiber logs which
provides some glow realistically when the appliance is operating.
The gas log sets covered in this document are heater rated units. These
units are equipped with a millivolt gas valve. The control knob is set to
the desired position, which maintains a continuous gas burning rate.
A spark ignition system (piezo) allows the gas pilot to be lit without the
use of matches or batteries and permits operation of the heater during
a power outage.
GENERAL INFORMATION
These Dual-Listed Gas Log Appliances are equipped with a specially designed
pilot utilizing an oxygen depletion sensor (ODS) which responds to the
amount of oxygen available in the room and shuts the heater off before the
oxygen level drops below 18%. The pilot can be relit only when fresh air is
available. Refer to the Combustion and Ventilation Air section.
These appliances are approved to be installed into an existing masonry
fireplace (built to UBC 37, Masonry Standards) or factory built solid
fuel, wood burning fireplace (listed to UL 127, Factory Built Fireplace
Standards) or a built-in Vent-Free Firebox (listed to Ventless Firebox
Enclosures for Gas-Fired Unvented Decorative Room Heaters to ANSI

Burn-in Period
During the first few times of operation of this appliance there will be some
odor due to the curing of the paint and burning off of lubricants used
in the manufacturing process. We recommend that you open windows
and ventilate the house during the initial burns. The paint emits non-toxic
odors during this process.
Depending on your use, the burn-in period may take a few hours or a few
days. Also if you have a sensitive sense of smell you may notice slight
odors during operating after the burn-in period is over.
KEEP YOUR HOUSE WELL VENTILATED DURING THE BURN-IN PERIOD.
THE ODOR AND HAZE EMITTED DURING THE BURN-IN PERIOD CAN BE
QUITE NOTICEABLE AND MAY SET OFF A SMOKE DETECTOR. MAKE
SURE SMOKE DETECTORS ARE NOT TOO CLOSE TO THE FIREBOX

centimeters) in length.
• The individual manual shut-off must be a T-handle type valve.
COMBUSTION AND VENTILATION AIR
This heater shall not be installed in a confined space or unusually tight
construction unless provisions are provided for adequate combustion
and ventilation air. The heater may be located in unusually tight construc
tion 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
NFPA 54 / ANSI Z223.1 (latest edition), Section on Air for Combustion
and Ventilation. Generally 50 ft
appliances in the space.
The National Fuel Gas Code, ANSI Z223.1/NFPA 54-latest edition defines
a confined space as a space whose volume is less than 50 cubic feet per
1000 Btu per hour (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 cubic feet per 1000 Btu per hour (4.8
m³ per kW) of the aggregate input rating of all appliances installed in
that space.
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 continu-
ous water vapor retarder with a rating or one perm (6 x 10-11 kg per
pa-sec-m2) or less with openings gasketed or sealed;
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 wall-ceiling
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 3.
Length x Width x Height = _____ ft
(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 ft 3 to determine the maximum BTU/Hr
the space can support.
(volume of space – ft 3) / 50 ft 3 = (Maximum BTU/Hr the space can
support)
Example: 3072 ft
3
/ 50 ft 3 = 61.44
or 61,440 BTU/Hr the space can support.
3. Add the BTU/Hr of all the fuel burning appliances in the space.

Example:
Vent-Free Heater 36,000 BTU/Hr
Gas Appliance #1 35,000 BTU/Hr

(actual amount of BTU/Hr used)
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 adjoining 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
- latest edition, Section on Air for Combustion and Ventilation.
b. Vent room directly to the outdoors. Refer to National Fuel Gas Code,
ANSI Z223.1 - latest edition, Section on Air for Combustion and Ven
tilation.
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 2 through 8 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.
• Position appliance in fireplace or firebox.
• Connect gas line.
• Secure appliance.
• Operate the appliance and check operation.
• Maintain adequate clearances for accessibility for purposes of servicing
and proper operation.
• Minimum clearances include any projections such as shelves, window
sills, mantels, spacers/standoffs or surfaces to combustible construction etc. above the appliance. Paint or lacquer used to finish the mantel
must be heat resistant in order to avoid discoloration.
Check Gas Type
-
This appliance can only be connected to the gas type specified on the
appliance rating plate. This appliance can not be modified in the field
for a different gas type. If the gas supply differs, DO NOT INSTALL the
appliance. Contact your dealer to obtain the correct appliance.
CLEARANCES
WARNING
If the area in which the heater may be operated is smaller
than that defined as an unconfined space or if the building is of unusually tight construction, you must provide
adequate combustion and ventilation air by one of the
methods described in the National Fuel Gas Code, ANSI
Z223.1, Section on Air for Combustion and Ventilation or
applicable local codes.
PREINSTALLATION
