convertible for use with other gases. 

2. Do not place propane/LP supply tank(s) inside any

structure. Locate propane/LP supply tank(s) outdoors
(propane/LP units only). 

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

4. This appliance shall not be installed in a bedroom or

bathroom.

5. Do not use this appliance as a wood-burning

Use only the logs provided with the appliance.

6. Do not add extra logs or ornaments such as pine cones,

vermiculite or rock wool. Using these added items can
cause sooting and poor combustion. Do not add lava
rock around base. Rock and debris could fall into the
control area of heater. 

7. This appliance is designed to be smokeless. If logs ever

appear to smoke, turn off appliance and call a qual

d

service person. Note: During initial operation, slight
smoking could occur due to log curing and
burning manufacturing residues. 

8. To prevent the creation of soot, follow the instructions

in

Cleaning and Maintenance

 section.

Keep the appliance area clear and free from
combustible materials, gasoline and other

ble vapors and liquids.

9. Before using furniture polish, wax, carpet cleaner, or

similar products, turn heater off. If heated, the vapors
from these products may create a white powder residue
within burner box or on adjacent walls or furniture.

10. This appliance needs fresh air ventilation to run prop-

erly. This appliance has an Oxygen Depletion Sensing
(ODS) safety shutoff system. The ODS shuts down the

if not enough fresh air is available. See

Air

for Combustion and Ventilation

, pages 4 through 6.

If appliance keeps shutting off, see

Troubleshooting,

pages 17 through 20.

part of the control system and any gas control which
has been under water. 

15. Turn appliance off and let cool before servicing. Only

a

service person should service and repair

appliance.

16. Operating appliance above elevations of 4,500 feet

could cause pilot outage. 

17. To prevent performance problems, do not use propane/

LP fuel tanks of less than 100 lbs. capacity.

18. Provide adequate clearances around air openings.
