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
excess of 1/2 psig (3.5 kPa).

ADEQUATE 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 National Fuel Gas Code, (ANSI Z223.1/NFPA54), defines a confined space as a space whose volume is less than 50
cubic feet per 1,000 BTU per hour (4.8 m
an unconfined space as a space whose volume is not less than 50 cubic feet per 1,000 BTU per hour (4.8 m
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) 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 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, and gas lines, and at other

GENERAL INSTALLATION INFORMATION
Figure 3 - Example of a Large Room with 1/2 Wall Divider
Counter
Cast Iron Stove
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:
L1 = 151/2 Ft., L2 = 12 Ft., W = 12 Ft., H = 8 Ft.
BTU/Hr = (151/2 + 12) x (12) x (8)
x 1000 = 52800 BTU/Hr
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)
x 1000 = 29760 BTU/Hr
50
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
10 58D6002

mocouple tip for natural. See Figure 19 for correct pilot flame.
If the pilot flame does not touch the thermocouple, then the burners cannot function reliably. See Figure 20 for incorrect
shape of pilot flame.

CHECKING BURNER FLAME
In normal operation at full rate after 15 minutes, the following flame appearances should be observed:
The left and right rear flames should be yellow and extend 1"-2" above middle logs. The yellow flames 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 flame patterns. Sooting and improper
burning will result.
During manufacturing, fabricating and shipping, various components of this appliance are treated with certain oils, films 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.

FOR YOUR SAFETY READ BEFORE LIGHTING
If you do not follow these instruction
exactly, a fire or explosion may result
causing property damage, personal
injury or loss of life.
WARNING
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 24.
B. BEFORE OPERATING 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. Do not use this appliance if any part of it has been under water. Immediately call a qualified 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.
