1.This appliance is only for use with the type of gas indicated on the rating plate. This appliance is not convertible for use with other gases.

2.This heater shall not be installed in a bedroom or bathroom, unless installed as a vented appliance (Variable Manually-Con- trolled Models Only). See Installing Damper Clamp Acces- sory for Vented Operation, page 10.

3.If you smell gas

•shut off gas supply

•do not try to light any appliance

•do not touch any electrical 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

4.Before installing in a solid fuel burning fireplace, the chimney flue and firebox must be cleaned of soot, creosote, ashes, and loose paint by a qualified chimney cleaner. Creosote will ig- nite if highly heated. Inspect chimney flue for damage. If dam- aged, operate heater with flue damper closed.

5.If fireplace has glass doors, never operate this heater with glass doors closed. If you operate heater with doors closed, heat buildup inside fireplace will cause glass to burst. Also if fire- place opening has vents at the bottom, you must open the vents before operating heater.

6.This log heater is designed to be smokeless. If logs ever appear to smoke, turn off heater and call a qualified service person. Note: During initial operation, slight smoking could occur due to log curing and heater burning manufacturing residues.

7.To prevent the creation of soot, follow the instructions in Clean- ing and Maintenance, page 20.

8.Before using furniture polish, wax, carpet cleaner, or similar products, turn heater off. If heated, the vapors from these prod- ucts may create a white powder residue within burner box or on adjacent walls or furniture.

9.This heater needs fresh, outside air ventilation to run properly. This heater has an Oxygen Depletion Sensing (ODS) safety shutoff system. The ODS shuts down the heater if not enough fresh air is available. See Air for Combustion and Ventilation, pages 4 through 6. If heater keeps shutting off, see Trouble- shooting, pages 22 through 24.

10.Do not run heater

•where flammable liquids or vapors are used or stored

•under dusty conditions

11.Do not use this heater to cook food or burn paper or other objects.

12.Do not use heater if any part has been exposed to or under water. Immediately call a qualified service technician to in- spect the room heater and to replace any part of the control system and any gas control which has been under water.

13.Do not operate heater if any log is broken. Do not operate heater if a log is chipped (dime-sized or larger).

14.Turn heater off and let cool before servicing. Only a qualified service person should service and repair heater.
