5. Any safety screen or guard removed for servicing
an appliance, must be replaced prior to operating the heater.
6. Installation and repair should be done by a qualifi ed
service person.
7. T o prevent malfunction and/or sooting, an unvented
gas heater should be cleaned before use and at least annually by a professional service person. More frequent cleaning may be required due to excessive lint from carpeting, bedding materials, etc. It is imperative that control compartments, burners and circulating air passageways be kept clean.
8. CARBON MONOXIDE POISONING: Early signs of carbon monoxide poisoning are similar to the fl u with headaches, dizziness and/or nausea. If you have these signs, obtain fresh air immediately. Have the heater serviced as it may not be operating properly.
9. The installation must conform with local codes or, in the absence of local codes, with the National Fuel
Gas Code, ANSI Z223.l/NFPA54.
10. This unit complies with the latest edition of ANSI Z21.11.2, Unvented Heaters.
11. Do not install the heaters in a bathroom or bedroom.
12. Correct installation of the ceramic fi ber logs, proper location of the heater, and annual cleaning are neces­sary to avoid potential problems with sooting. Sooting, resulting from improper installation or operation, can settle on surfaces outside the fi replace. See log place- ment instructions for proper installation.
20307670
13. Avoid any drafts that alter burner fl ame patterns. Do not allow fans to blow directly into fi replace. Do not place a blower inside burn area of fi rebox. Ceiling fans may create drafts that alter burner fl ame patterns. Sooting and improper burning will occur.
14. CAUTION: Candles, incense, oil lamps, etc. produce combustion byproducts including soot. Vent-free appliances will not fi lter or clean soot produced by these types of products. In addition, the smoke and/or aromatics (scents) may be reburned in the vent-free appliance which can produce odors. It is recommended to minimize the use of candles, incense, etc. while the vent-free appliance is in operation.

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.
