materials, gasoline and other fl ammable vapors and
liquids.
18. Unvented gas heaters are a supplemental zone heater.
They are not intended to be the primary heating appliance.
19. 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, additional mechanical ventilation is
recommended.
20. During manufacturing, fabricating and shipping, various
components of this appliance are treated with certain
oils, fi 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.

IMPORTANT SAFETY INFORMATION
The initial break-in operation should last four 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.
21. 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.
22. The appliance must be isolated from the gas supply
piping system by closing its equipment shutoff valve
during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 psig
(3.5 kPa).
23. Do not use this room heater if any part has been under
water. Immediately call a qualifi ed service technician
to inspect the room heater and to replace any part of
the control system and any gas control which has been

IGNITION CONTROLS
Piezo ignitor allows ignition of the pilot without the use of
matches or batteries.
Millivolt and EcoLogic® 2.0 controls have four (4)
positions:
OFF - All gas to the gas logs is shut off at the
valve.
IGN - Valve position to light/maintain a standing
pilot.
ON - Valve position to turn ON/OFF log set with
remote switch/thermostat.
LOW/HI - Variable position to control fl ame height (heat output). Both front and rear burners
are in operation to provide realistic glow
and yellow fl ame.
PILOT
The gas log heater is fi tted with a specially designed safety
pilot light (ODS assembly) which senses the amount of
oxygen available in the room and shuts the gas log heater
off if the oxygen level begins to drop below a satisfactory
level. The pilot can only be re-lit when adequate fresh air
is available.
THERMAL GENERATOR
The millivolt gas log pilot is fi tted with a millivolt generator
to provide power for remote activation.
COLD CLIMATE OPTION (IPI Models Only)
NOTE: If you live in a cold climate, seal all cracks around
your appliance and wherever cold air could enter the room,
with noncombustible material. It is especially important to
insulate the outside chase cavity between the studs and
under the fl oor on which the appliance rests, if the fl oor is
above ground level.
Your fi replace is equipped with an intermittent pilot ignition
(IPI) control. An IPI control with a standing pilot option
provides the dual benefi t of an economical and environ-
mentally responsible product and one which lights easily
even in the coldest climates. When in intermittent pilot

mode (as it comes from the factory), your pilot remains
unlit until needed, saving you fuel. Standing pilot mode,
by comparison, is characterized by a continuously burning
pilot. The benefi t of a pilot which lights only when needed
is fuel savings. However, with no pilot burning in your fi re-
place, units operating in colder climates may experience
delayed start up or lock out. Because colder air is heavier
than milder air and there is no pilot burning to maintain
a warm stable temperature in your fi rebox, establishing
a draft to aid ignition becomes diffi cult. This is perfectly
normal but can be somewhat frustrating.

T o remedy this issue, your fi replace has been designed with
a cold climate pilot option, which, when active, maintains
a warmer temperature inside your fi rebox to make ignition
faster and more effi cient. Operating your appliance in cold
climate (aka standing) pilot mode will prohibit the need for
multiple ignition attempts and will prevent the system from
delaying start up or locking out.
To activate the cold climate option, simply move the cold
climate toggle switch located on the right side of the black
control center to the “On” (left) position. (Figure 3) Y ou can
operate your appliance in this mode regardless of whether
you are using a remote control, wall switch or thermostat.

OPERATING INSTRUCTIONS
Avoid any drafts that alter burner fl ame patterns. Do
not allow fans to blow directly into the fi replace. Do not
place a blower inside the burn area of the fi rebox. Ceiling
fans may create drafts that alter fl ame patterns. Sooting
and improper burning will result.
During manufacturing, fabricating and shipping, various
components of this appliance are treated with certain oils,
fi 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 four 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 will be slight
and will disappear with continued use.
