VENTED NATURAL GAS LOGS

SAFETY
INFORMATION

Carbon Monoxide Poisoning:

 Early

signs of carbon monoxide poisoning re-
semble the flu, with headaches, dizziness,
or nausea. If you have these signs, the log set
may not be working properly. Get fresh air
at once!
 Have log set serviced. Some people
are more affected by carbon monoxide than
others. These include pregnant women,
people with heart or lung disease or anemia,
those under the influence of alcohol, and
those at high altitudes.

Natural Gas:

 Natural gas is odorless. An

odor-making agent is added to the gas. The
odor helps you detect a gas leak. However,
the odor added to the gas can fade. Gas may
be present even though no odor exists.

Make certain you read and understand all
Warnings. Keep this manual for reference.
It is your guide to safe and proper operation
of this log set.

 WARNINGS

IMPORTANT: Read this owner’s
manual carefully and completely
before trying to assemble, oper-
ate, or service this log set. Im-
proper use of this log set can cause

 WARNING: Any change to this

log set or its controls can be
dangerous.

1.

This appliance, as supplied, is only for
use with the type of gas indicated on
the rating plate. This appliance is con-
vertible for use with propane/LP, using
the GA9053 or GA9153 pilot kit.

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 inches 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 burn-
ing fireplace, the chimney flue and fire-
box 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.

5.

You must operate this log set with a fire-
place screen in place. Make sure fireplace
screen is closed before running log set.

6.

This log set is designed to be smoke-
less. If logs ever appear to smoke, turn
off appliance and call a qualified ser-
vice person. 

Note:

 During initial op-

eration, slight smoking could occur due
to log curing and the burning of manu-
facturing residues. You may wish to add
more ventilation by opening a window.

7.

To reduce the creation of soot, follow
the instructions in Cleaning and Main-
tenance
, page 17.

8.

Do not allow fans to blow directly into
the fireplace. Avoid any drafts that al-
ter burner flame patterns. Ceiling fans
can create drafts that alter burner flame
patterns. Altered burner patterns can
increase sooting.

9.

Do not use a blower insert, heat ex-
changer insert or other accessory not
approved for use with this log set.

10. This log set needs fresh, outside air ven-

tilation to run properly. See Air for
Combustion and Ventilation
, pages 4
through 6.

11. Do not run log set

• where flammable liquids or vapors

are used or stored

• under dusty conditions

12. Do not burn solid fuel in the fireplace

after installing the log set. Do not use
this log set to cook food or burn paper
or other objects.

13. Log set becomes very hot when in use.

Keep children and adults away from hot
surface to avoid burns or clothing igni-
tion.  Log set will remain hot for a time
after shutdown. Allow surface to cool
before touching.

14. Carefully supervise young children

when they are in the room with log set.

15. Do not use appliance if any part has been

exposed to or under water. Immediately
call a qualified service technician to in-
spect the room appliance and to replace
any part of the control system (if using
GA9053 or GA9153) and any gas con-
trol which has been under water.

16. To help prevent breakage, new logs

must be broken-in (see Curing logs
page 13).

17. Turn log set off and let cool before ser-

vicing, installing, or repairing. Only a
qualified service person should install,
service, or repair log set.

 WARNING: Keep flue open

when operating unit.
