Keep the log set area clear and 

free from combustible materials, 

gasoline  and  other  flammable 

vapors and liquids.

Children  and  adults  should  be 

alerted to the hazard of high tem-

perature and should stay away to 

avoid burns or clothing ignition.

1.  Do not place propane/LP supply tank(s) in

-

side any structure. Locate propane/LP supply 

tank(s) outdoors (propane/LP units only).

2.  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

3.  Never install the log set

• in a recreational vehicle

• where curtains, furniture, clothing or other 

flammable objects are less than 42" from the 

front, top or sides of the log set.

• in high traffic areas

• in windy or drafty areas 

4.  Before installing in a solid fuel burning fire

-

place, the chimney flue and firebox must be 

cleaned of soot, creosote, ashes and loose paint 

by a qualified chimney cleaner. Creosote will 

ignite if highly heated. Inspect chimney flue 

for damage. If damaged, repair flue before 

operating appliance.

5.  Do not operate heater if any log is broken. Do 

not operate heater if a log is chipped (dime-

sized or larger).

6.  This log set is designed to be smokeless. If 

logs ever appear to smoke, turn off appliance 

and call a qualified service person. 

Note:

 

During initial operation, slight smoking could 

occur due to log curing and the burning of 

manufacturing residues. You may wish to add 

more ventilation by opening a window.

7.  To reduce the creation of soot, follow the instruc

-

tions in 

Cleaning and Maintenance

, page 12.

use propane/LP fuel tank of less than 100 lb. 

capacity (propane/LP units only).

any gas control which has been under water.

installing or repairing. Only a qualified service 

person should install, service or repair log set.

openings.
