  WARNING:  Do  not  place 

clothing  or  other  flammable 

material  on  or  near  the  appli-

ance. Never place any objects 

in the heater.

 WARNING: Due to high tem-

peratures, the appliance should 

be located out of traffic and away 

from furniture and draperies.

 WARNING: Heater becomes 

very  hot  when  running.  Keep 

children and adults away from 

hot surfaces to avoid burns or 

clothing ignition. Heater will re-

main hot for a time after shutoff. 

Allow  surfaces  to  cool  before 

touching.

 WARNING: Carefully super-

vise young children when they 

are in the room with the heater.

 WARNING: Make sure a fire-

place screen is in place before 

running heater.

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

inside any structure. Propane/LP supply 

tank(s) must be placed outdoors.

2.  This heater should not be installed in a 

bedroom or bathroom unless installed as 

a vented appliance.

3.  This heater needs fresh 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 

6 through 8. If heater keeps shutting off, 

see 

Troubleshooting

, page 24.

4.  Do not add extra logs or ornaments such 

as pine cones, vermiculite, or rock wool. 

Using these added items can cause soot-

ing. Do not add lava rock around base. 

Rock and debris could fall into the control 

area  of  heater. After  servicing,  always 

replace screen before operating heater.

SAFETY

5.  If fireplace has glass doors, never operate 

this heater with glass doors closed. If you 

operate heater with doors closed, heat will 

build-up inside fireplace and cause glass 

to  burst.  If  fireplace  opening  has  vents 

at the bottom, you must open the vents 

before operating log set. Always operate 

heater with glass doors fully open.

6.  This log heater is designed to be smoke-

less. If logs ever appear to be smoking, 

turn off heater and call a qualified service 

technician. 

NOTE: During initial operating, 

slight smoking could occur due to log cur-

ing and heater burning off manufacturing 

residues.

7.  To prevent the creation of soot, follow the 

instructions under 

Care and Maintenance 

page 23.

8.  Do not run heater:

• Where flammable liquids or vapors are 

used or stored.

• Under dusty conditions.

9.  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.

10. Do not use heater if any part has been 

under water. Immediately call a qualified 

service  technician  to  inspect  the  room 

heater  and  to  replace  any  part  of  the 

control system and any gas control which 

has been under water.

11. Turn off and unplug heater and let cool 

before servicing. Only a qualified service 

person should service and repair heater.

12. Operating  heater  above  elevations  of 

4,500 feet could cause pilot outage.

13. Do not use this heater if any log is broken. 

Do not operate heater if a log is chipped 

(dime-size or larger).

14. To  prevent  performance  problems,  do 

not use propane/LP fuel tank of less than 

100 lbs. capacity.

15. Solid  fuels  should  not  be  burned  in 

fireplace  in  which  a  vent-free  log  set  is 

installed. Do not use this heater to cook 

food or burn paper or other objects.
