13. Correct installation of the ceramic fiber logs, proper
location of the heater, and annual cleaning are neces-
sary to avoid potential problems with sooting. Sooting,
resulting from improper installation or operation, can
settle on surfaces outside the fireplace. -See log place-
.ment instructions for proper installation.
14. Avoid any drafts that alter burner flame patterns. Do not
allow -fans to blow directly into fireplace. Do not place
a blower inside burn area of firebox. Ceiling fans may
create drafts that alter burner flame patterns. Sooting
and improper burning will occur.
15. CAUTION:. Candies, incense, oil lamps, etc. produce
combustion byproducts including soot. Vent -free appli-
ances will not filter or clean soot produced by these
types of products. In addition, the smoke and/or aro-
matics (scents) may be reburnt in the vent -free appli
ance which can produce odors. It recommended to
minimize the use of candles, incense, etc. while, the
vent -free appliance is in operation.
16. An unvented gas -fired heater uses air (oxygen) from
the room in which it is installed. Provisions for adequate
combustion and ventilation air must be provided. See
installation guidelines. .
17. Keep room area clear and free from combustible
materials, gasoline and other flammable vapors and
liquids.
.8. Unvented gas heaters are a supplemental zone heater.
They are not intended to be a primary heating appli-
ance.
19. Unvented gas heaters emit moisture into the .living
area. In most homes of average construction, this
does not pose a problem. In houses of extremely
tight construction, additional mechanical ventilation is
recommended.
20. During manufacturing, fabricating and shipping, various
components of this appliance are treated with certain
oils, films or bonding agents. These chemicals are not
harmful but may produce annoying smoke and smells
as they are burned off during the initial operation of the
appliance; possibly causing headaches, or eye or lung
irritation. This is a normal and temporary occurrence.

The 1 /2" gas line may enter either from the left side or right
side of the firebox. Gas access.holes are. provided on both_
sides of the firebox'.
A listed manual shutoff valve must be installed upstream
of the appliance. A union tee and.plugged 1/8 NPT pres-
sure tapping point should be.installed upstream of hte.
appliance.
IMPORTANT. Install main gas valve (equipment shutoff
Valve) in an accessible location. The main gas valve is
for turning on or shutting off the -gas to the fireplace.
A sediment trap may be upstream of the heater to prevent
moisture and contaminants from passing through trap to
the heater controls -and burners. Failure to do so could
prevent the heater from operating reliably. Consult appli-
cable codes.
An external regulator must be used on all propane/L.RG:
heaters, in addition to the regulator fitted to.the heater, to
reduce the supply tank pressure to 13" w.c. (maximum).
Any copper tubing used to supply propane / L.P.G. from
the tank must be internally tinned.
NOTE: When connecting propane / L.P.G. vent -free
room heaters, you must use pipe sealant resistant to
propane / L.P.G.
IMPORTANT: Hold heater regulator with a.wrench to
prevent movement when connecting to inlet.piping.
Check gas type: The -gas supply must be the same as
stated on the heater's rating plate. If the gas supply.
is different, DO NOT INSTALL -THE HEATER. Contact
your dealer for the correct model.. .
61D1013
Connecting directly to an unregulated
propane / L.P.G. tank can cause an
explosion.
Do not connect directly to natural gas 1/2
PSI or 2 PSI systems. Always make sure
natural gas pressure is regulated 10.5 w.c.
(maximum before operating the unit)-.
After completing connection, test all gas joints from the
.gas meter to the gas heater regulator for leaks. Using
soap and water solution or a gas sniffer. DO NOT USE

COMBUSTION AIR
1. Locate combustion air assembly at an exterior location
which is not likely to be accidentally blocked in any man-
ner. Locate assembly a min. of 12"above the snow line
to prevent blockage by snow accumulation.
I Never mount the combustion air inlet assembly in a
garage or storage area where combustible. fumes such
as gasoline might be drawn into the fireplace.
3.. Combustion air can be drawn from the crawl space un-
der a house when an adequate supply, of air is provided
by open ventilation. .
4. CAUTION: Do not take combustion air from attic
space or garage space.
5. Locate air supply inlet at least 3' away from any appli-
ance vent terminal.
6. Avoidextremely long runs and numerous turns in the
duct leading from the fireplace to the combustion air
assembly. These conditions increase the resistance to:
the free flow of air through the duct. Refer to Figures
