ANSIZ223.1 or NFPA54 which can be obtained from:
WARNING
American National Standards Institute, Inc.
1430 Broadway
New York, NY 10018
or
National Fire Protection Association, Inc.
Batterymarch Park
Quincy, MA 02269
Due to high temperatures, do not install the heater:
• Where curtains, furniture, clothing or other flammable objects are less than
42" from the front of the heater.
• In high traffic areas.
• In windy or drafty areas.
DO NOT PLACE CLOTHING OF OTHER FLAMMABLE MATERIAL ON OR NEAR
THE APPLIANCE.
ADEQUATE COMBUSTION AND VENTILATION AIR
This heater shall not be installed in a confined space unless provisions are provided for adequate combustion and ventilation air.
(a) Walls and ceiling exposed to the outside atmosphere have a continuous water vapor retarded
with a rating of 1 perm (6 x 1011 kg per pa-sec-m²) or less with openings gasketed or sealed , and
(b) Weather stripping has been added on openable 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, gas lines, and at other openings.
The National Fuel Gas Code defines a confined space as a space whose volume is less than 50 cubic feet
per 1,000 BTU per hour (4.8m³ per kw) of the aggregate input rating of all appliances installed in that space
and an unconfined space is defined as a space whose volume is not less than 50 cubic feet per 1,000 BTU
per hour (4.8m³ 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 that unconfined space.
6
INSTALLATION
The following formula can be used to determine the maximum
heater rating per the definition of unconfined space:
BTU/HR = (L1+L2) Ft x (W) Ft x (H) Ft x 1000
50
Consider two connecting rooms with an open area between,
with the following dimensions:( See Fig. 2, Example)
L1=15-1/2 Ft., L2=12 Ft., W=12 ft., H=8Ft
50
=52800 BTU/HR
If there were a door between the two rooms the calculation would
be based only on the room with the heater.
BTU/HR=(15-1/2) x (12) x (8) x 1000
50
=29760 BTU/HR
WARNING
When installing the appliance directly on carpeting, tile or other combustible
material, other than wood flooring, the appliance must be installed on a
metal or wood panel extending the full width and depth of the appliance.
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, provide
adequate combustion and ventilation air by one of the methods described in the
National Fuel Gas Code, ANSI Z223.1, Section 5.3, or applicable local codes.
WARNING
FIGURE 2.
Ensure the minimum clearances shown in FIGURE 3 are maintained for
accessibility for purposes of servicing and proper operation. Left and

GAS CONNECTION
A qualified gas appliance installer must connect the fireplace to the gas supply.
Consult all local codes.
Use new black iron or steel pipe only. Internally tinned copper tubing can be used
in some areas when permitted by local codes. Only use pipe of 1/2" or greater
diameter to allow full gas volume to heater. Excessive pressure loss will occur if the
pipe is too small.
A manual shutoff valve, union and plugged 1/8" NPT pressure tapping point must be
installed upstream of the heater (FIGURE 5).
A sediment trap must be installed upstream of the heater to prevent moisture and
contaminants from passing through the pipe to the heater controls and burners.
Failure to do so could prevent the heater from operating reliably (FIGURE 5).

OPERATING INSTRUCTIONS
Avoid any drafts that alter the burner flame patterns. Do not allow fans to blow directly into the heater. Do not place
a blower inside burn area of firebox. Ceiling fans may create drafts that alter burner flame patterns. Sooting and
improper burning will occur.
This vent-free gas heater is intended to be smokeless. If logs appear to smoke, turn off the heater and call a qualified
service person. Initial burn off may cause slight smoke and odor during the first four hours of operation.
WARNING
FOR YOUR SAFETY READ BEFORE LIGHTING
WARNING: If you do not follow these instructions exactly, a fire or explosion may
result causing property damage, personal injury or loss of life.
A.
This appliance is equipped with an ignition device (piezo) which automatically lights the pilot. If piezo fails,
then light the pilot using matches. Refer to match lighting instructions (page 13). When lighting the pilot,
follow these instructions exactly.
B.
BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because
some gas is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
• Do not attempt to light any appliance.
• Do not touch any electric switch; do not use any phone in your building.
• Immediately call your gas supplier from a neighbor's phone. Follow the gas supplier's instructions.
• If you cannot reach your gas supplier, call the fire department.
C.
Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not push in or
turn by hand, don't try to repair it, call a qualified service technician. Force or attempted repair may result
in a fire or explosion.
D.

WARNING
OPERATING INSTRUCTIONS
Wait 30 seconds before readjusting the heater when the control has been turned
down to a lower setting.
MATCH LIGHTING INSTRUCTIONS
If the pilot will not light using the piezo ignitor, you can light the pilot with a match. First, locate the pilot. The pilot
is located between the two burner tubes on the right end (facing the unit), inside the firebox. To light pilot with a
match, move the gas control (knob 1, pg. 12) to the pilot position and hold down. Light match and place near pilot.
Once pilot is lit, continue to hold the knob for about ten seconds. Then follow steps 7 thru 10 on page 12.
CHECKING FLAME APPEARANCE
Flames from the pilot, front and rear burner should be visually checked when the heater is installed. In addition a
periodic visual check of the flames should be made.
PILOT FLAME
The pilot flame should always be present when the
heater is in operation and should just touch the top of
the thermocouple tip (FIGURE 9).
If the pilot flame does not touch the thermocouple,
then the main burner is unlikely to function reliably
(FIGURE 10).
FIGURE 9. Pilot Flame
FIGURE 10. Incorrect Shape of Pilot Flame
CLEANING / SERVICING
Annual inspection and cleaning by your dealer or qualified service technician is recommended to prevent
malfunction and/or sooting.
WARNING
