adequate combustion and ventilation air must be pro-
vided. See page 8.
16. Keep room area clear and free from combustible materi-
als, gasoline and other ammable vapors and liquids.
17. Unvented gas heaters are a supplemental zone heater. They
are not intended to be a primary heating appliance.
18. Unvented gas heaters emit moisture into the living area.
In most homes of average construction, this does not pose
a problem. In houses of extremely tight construction,
addition mechanical ventilation is recommended.
19. During manufacturing, fabricating and shipping, various
components of this appliance are treated with certain
oils, lms or bonding agents. These chemicals are not
harmful but may produce annoying smoke and smells
as they are burned off during the initial operation of the
appliance; possibly causing headaches or eye or lung
irritation. This is a normal and temporary occurrence.
The initial break-in operation should last two to three
hours with the burner at the highest setting. Provide
maximum ventilation by opening windows or doors to
allow odors to dissipate. Any odors remaining after this
initial break-in period will be slight and will disappear
with continued use.
20. Input ratings are shown in BTU per hour and are for
elevations up to 2,000 feet. For elevations above 2,000
feet, input ratings should be reduced 4 percent for each
1,000 feet above sea level. Refer to the National Fuel
Gas Code.
21. The appliance and its appliance main gas valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in

GENERAL INSTALLATION INFORMATION
ADEQUATE COMBUSTION AND VENTILATION AIR
This heater shall not be installed in a conned space or unusually tight construction unless provisions are provided for
adequate combustion and ventilation air.
The National Fuel Gas Code, (ANSI Z223.1/NFPA54), denes a conned space as a space whose volume is less than 50
cubic feet per 1,000 BTU per hour (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space and
an unconned space as a space whose volume is not less than 50 cubic feet per 1,000 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 unconned space.
UNUSUALLY TIGHT CONSTRUCTION IS DEFINED AS CONSTRUCTION WHERE…
a) walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of 1 perm
(6 x 1011 kg per pa-sec-m2) or less with openings gasketed or sealed;
b) weather striping 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
oors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and at
other openings.
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.

The following formula can be used to determine the maximum heater rating per the denition of unconned space:
BTU/Hr = (L1 + L2) Ft x (W) Ft x (H) Ft
50
Consider two connecting rooms with an open area between, with the following dimensions:
L1 = 151/2 Ft., L2 = 12 Ft., W = 12 Ft., H = 8 Ft.
BTU/Hr = (151/2 + 12) x (12) x (8)
50
If there were a door between the two rooms the calculation would be based only on the room with the heater.
BTU/Hr = (151/2) x (12) x (8)

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, NFPA54, Section 5.3 or applicable local codes.

CHECKING BURNER FLAME
In normal operation at full rate after 15 minutes, the follow-
ing flame appearances should be observed:
The left and right rear ames should be yellow and extend 1"-2" above
the log top surfaces. The yellow ames should not contact the logs.
There should be glowing embers on the front surface of the middle
log. Note: The flames and embers will be an opaque orange
color during the burn off time.
OPERATING INSTRUCTIONS
Avoid any drafts that alter burner flame patterns. Do not allow
fans to blow directly into the stove. Do not place a blower inside the
burn area of the stove. Ceiling fans may create drafts that alter ame
patterns. Sooting and improper burning will result.
During manufacturing, fabricating and shipping, various components of this appliance are treated with certain oils, lms or
bonding agents. These chemicals are not harmful, but may produce annoying smoke and smells as they are burned off during
the initial operation of the appliance, possibly causing headaches or eye or lung irritation. This is a normal and temporary
occurrence.
The initial break-in operation should last two to three hours with the burner at the highest setting. Provide maximum ventila-
tion by opening windows or doors to allow odors to dissipate. Any odors remaining after this initial break-in will be slight
and will disappear with continued use.

A. This appliance is equipped with an ignition device which automatically lights the pilot. If the piezo is not
working properly, see “Match Lighting Instructions,” page 20.
B. BEFORE OPERATING smell all around the appliance area for gas. Be sure to smell next to the oor
because some gas is heavier than air and will settle on the oor.
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 re 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 qualied service technician. Force or attempted repair may result
in a re or explosion.
D. Do not use this appliance if any part of it has been under water. Immediately call a qualied service tech-
nician to inspect the appliance and to replace any part of the control system and any gas control that has
been under water.
OPERATING INSTRUCTIONS
If you do not follow these instruction
exactly, a fire or explosion may result
causing property damage, personal
injury or loss of life.

OPERATING INSTRUCTIONS
1. STOP! Read the safety information label.
2. Make sure the manual shutoff valve is fully open.
3. This gas log set is equipped with an ignition device (piezo) which automatically lights the pilot. If piezo
ignitor does not light the pilot, refer to instructions for “Match Lighting Instructions”, page 20.
4. Turn gas control knob clockwise to the OFF position, set the thermostat to the lowest setting and
turn ON/OFF switch to OFF position.
5. Wait (5) minutes to clear out any gas. Then smell for gas, including near the oor. If you smell gas, STOP!
Follow the instructions under “What To Do if You Smell Gas,” page 18. If you don't smell gas, go to
next step.
6. From OFF position, turn the gas control knob counterclockwise to IGN position. Push in control
knob for 5 seconds. NOTE: If you are running the heater for the first time, it will be neces-
sary to press in the control knob for 30 seconds or longer to allow air to bleed out of the
gas piping.
7. With the control knob pushed in, the battery powered ignition will light the pilot.
8. Continue pushing the control knob in for a further 10 seconds to prevent the ame detector from shutting
off the gas while the probe is warming up. Release the control knob.
9. Turn gas control knob counterclockwise to the ON position.
10. After the pilot has been lit for one minute, the burners can be turned on. Turn the ON/OFF switch to ON
position or adjust thermostat to desired setting. NOTE: To use the optional thermostat function (if
installed), the control knob must be set to “ON” and the ON/OFF Switch must be in the “OFF”
position.
11. If the gas logs will not operate, follow the instructions “To Turn Off Gas To Heater” below and call your
service technician or gas supplier.
