COMBUSTION AND VENTILATION AIR
• Test gage connections are provided on the
front of the gas control valve (identified A for
the manifold side and E for inlet pressure).
These heaters shall not be installed in a con-
fined space. The heater may be located in
unusually tight construction provided the
space is unconfined, or if confined, is pro-
vided with two permanent openings commu-
nicating directly with an additional room(s)
of sufficient volume so that the combined
volume of all connected spaces meets the
criteria for an unconfined space, (National
Fuel Gas Code ANSI Z223.1 (latest edition),
Section 5.3). Generally 50 ft 3 per 1,000 BTU
input of all operating appliances in the space.
• Due to high temperatures, the heater should
belocatedoutoftrafficandawayfromfurniture
and draperies.
• Input ratings are shown in BTU per hour and
are for elevations up to 7,000 feet. Operating
heateraboveelevationsof7,000feetmaycause
ODS pilot outage.
• Children and adults should be alerted to the
hazardofhighsurfacetemperaturesandshould
stay away to avoid burns or clothing ignition.
• Ensure that the heater is clean when operat-
ing.Excessivedustaccumulationontheburner
and logs will increase the amount of carbon
monoxide formation and could lead to carbon
monoxide poisoning and death.
• Youngchildrenshouldbecarefullysupervised
when they are in the same room with the heater.
• Do not place clothing or other flammable
material on or near the heater for the purpose
of drying.
The National Fuel Gas Code defines a con-
fined space as a space whose volume is less
than 50 ft 3 per 1,000 BTU/Hr (4.8 m3 per kw)
of the aggregate input rating of all appliances
installed in that space and an unconfined
space as a space whose volume is not less
than 50 ft 3 per 1,000 BTU/Hr (4.8 m3 per kw)
of the aggregate input rating of all appliances
installed in that space. Rooms communicat-
ing directly with the space in which the appli-
ances are installed, through openings not
furnishedwithdoors,areconsideredapart of
the unconfined space.
CODES
• Installation and repair should be done by a
qualified service person. The heater should be
inspected before use and at least annually by a
professionalserviceperson.Morefrequentclean-
ing may be required due to excessive lint from
carpeting, bedding material, etc. It is important
that control compartments, burners and circulat-
ing air passageways of the heater be kept clean.

(Maximum BTU/Hr the space can support)
To provide for the lowest possible shelf sur-
face, combustible materials used to support a
utility shelf directly above these appliances
should be positioned just above the appliance
top spacers. The minimum height from the
base of the appliance to the underside of com-
bustible materials used to construct a utility
shelf is 43-1/4” (1099 mm).
Example: 3072 ft 3 / 50 ft 3 = 40.96
or 40,960 BTU/Hr the space can support.
b. Vent room directly to the outdoors. Refer to
National Fuel Gas Code, ANSI Z223.1 1992,
Section 5.3.
3. Add the BTU/Hr of all the fuel burning appli-
ances in the space.
If the actual BTU/Hr used is less than the
maximumBTU/Hrthespacecansupport, then
the space is an unconfined space. You will
need no additional fresh air ventilation for an
unconfined space.

ommended to prevent the fibers from pricking
your skin. If the skin is pricked, wash gently
with soap and water. Replace the logs as de-
tailed in Step 8 Assembling the Logs.
3. When lit for the first time, the appliance will
emit a slight odor for an hour or two. This is
due to the “burn-in” of the internal paints and
lubricants used in the manufacturing process.
Additionally, when lit for the first time, this
appliance may produce smoke, this is normal
and should be expected. For the first few
hours, operate the appliance with doors and
windows open to encourage the dissipation of
smoke and fumes.
If, after a period of use, the flames start to
exhibit unusual shapes and behavior, or the
burners fail to ignite smoothly, then the burner
holes may require some cleaning. If this hap-
pens, it is preferable to contact your nearest
dealer to get the appliance serviced.
