IMPORTANT SAFETY INFORMATION
INSTALLER: Please leave these instructions with the owner.
OWNER: Please retain these instructions for future reference.
IMPORTANT: Read these instructions carefully before installing or trying to operate this heater.
WARNING: Any change to this heater or its controls can be dangerous.
Improper installation or use of the heater can cause serious injury or
death from fire, burns, explosion or carbon monoxide poisoning.
1.
2.
CARBON MONOXIDE POISONING: Early signs of carbon monoxide poisoning are similar to the
flu with headaches, dizziness and/or nausea. If you have these signs, obtain fresh air immediately.
Have the heater serviced as it may not be operating properly.
The installation must conform with local codes or, in the absence of local codes, with the National
Fuel Gas Code, ANSI Z223.1.
3.
4.
5.
The 9830N/9830L vent-free gas heater system cannot be installed in a bedroom.
Do not install the heaters in a bathroom.
WARNING: Improper installation, adjustment, alteration, service or maintenance can cause injury
or property damage. Refer to this owner's manual. Installation and service must be performed by

Topreventmalfunctionand/orsooting, anunventedgasheatershouldbecleanedatleastannually
byaprofessionalserviceperson.Morefrequentcleaningmayberequiredduetoexcessivelintfrom
carpeting, etc. It is imperative that control compartments, burners and circulating air passageways
be kept clean.
7.
8.
Correct placement of the ceramic fiber logs is necessary to avoid problems with sooting. Sooting
can settle on surfaces outside the heater and cause discoloration. See the appropriate sections of
this manual for instructions.
WARNING: Do not allow fans to blow directly into the fireplace. Avoid any drafts that alter burner
flame patterns. 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.

IMPORTANT SAFETY INFORMATION
12.
13.
Do not place clothing or other flammable material near the appliance.
Keep appliance area clear and free from combustible materials, gasoline and other flammable
vapors and liquids.
14.
15.
Any safety screen or guard removed for servicing must be replaced prior to operating the heater.

four hours of operation.
16.
Input ratings are shown in BTU per hour and are for elevations up to 2,000 feet. For elevations
above 2,000 feet, input ratings should be reduced 4 percent for each 1,000 feet above sea level.
Refer to the National Fuel Gas Code.
17.
18.
Theheateranditsindividualshutoffvalvemustbedisconnectedfromthegassupplypipingsystem
during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).
The heater must be isolated from the gas supply piping system by closing its individual manual
shutoff valve during any pressure testing of the gas supply piping system at test pressures equal
to or less than 1/2 psig (3.5 kPa).

ITEMS REQUIRED FOR INSTALLATION
ITEMS REQUIRED FOR INSTALLATION
Ensure that the following items are available before proceeding with installation:
• External regulator (for propane/LPG only)
• Piping which complies with local codes
• Pipe sealant approved for use with
• Manual shutoff valve
• Sediment trap
• Pipe wrench
propane/LPG (resistant to sulfur compounds)
CODES
Adhere to all local codes or in their absence, the latest edition of THE NATIONAL FUEL GAS CODE ANSI
Z223.1 or NFPA54 which can be obtained from:
American National Standards Institute, Inc.
1430 Broadway
National Fire Protection Association, Inc.
Batterymarch Park
or
New York, NY 10018
Quincy, MA 02269
Due to high temperatures, do not install the heater:
• Where curtains, furniture, clothing or other flammable objects are less than 42"
from the front of the heater.
• In high traffic areas.
• In windy or drafty areas.
DO NOT PLACE CLOTHING OR OTHER FLAMMABLE MATERIAL ON OR NEAR THE
APPLIANCE.
ADEQUATE COMBUSTION AND VENTILATION AIR
This heater shall not be installed in a confined space or unusually tight construction unless provisions are
provided for adequate combustion and ventilation air.
Unusually tight construction is defined as construction where:
(a) Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder
with a rating of 1 perm (6 x 10½11kg per pa-sec-m ) or less with openings gasketed or sealed, and
(b) Weather stripping has been added on openable windows and doors, and
(c) Caulking or sealants are applied to areas such as joints around window and door frames,
between soleplates and floors, between wall-ceiling joints, between wall panels, at penetrations
for plumbing, electrical, and gas lines, and at other openings.
The National Fuel Gas Code defines a confined space as a space whose volume is less than 50 cubic
feet per 1,000 BTU per hour (4.8m3per kw) of the aggregate input rating of all appliances installed in that
space and an unconfined space is defined as a space whose volume is not less than 50 cubic feet per
1,000 BTU per hour (4.8m3per kw) of the aggregate input rating of all appliances installed in that space.
Rooms communicating directly with the space in which the appliances are installed, through openings not
furnished with doors, are considered a part of the unconfined space.

When installing the appliance directly on carpeting, tile or other combustible
material, other than wood flooring, the appliance must be installed on a metal or
wood panel extending the full width and depth of the appliance.
If the area in which the heater may be operated is smaller than that defined as an
unconfined space or if the building is of unusually tight construction, provide
adequate combustion and ventilation air by one of the methods described in the
National Fuel Gas Code, ANSI Z223.1, Section 5.3, or applicable local codes.
Ensure the minimum clearances shown in FIGURE 3 are maintained for accessibility
for purposes of servicing and proper operation. Left and right clearances are
determined when facing the front of the heater.
Maintain
these
clearances to ensure
adequate space around
air opening for proper
operation.

GAS CONNECTION
A qualified gas appliance installer must connect the fireplace to the gas supply.
Consult all local codes.
Use new black iron or steel pipe only. Internally tinned copper tubing can be used
in some areas when permitted by local codes. Only use pipe of 1/2" or greater
diameter to allow full gas volume to heater. Excessive pressure loss will occur if the
pipe is too small.
A manual shutoff valve, union and plugged 1/8" NPT pressure tapping point must be
installed upstream of the heater (FIGURE 4).
A sediment trap must be installed upstream of the heater to prevent moisture and
contaminants from passing through the pipe to the heater controls and burners.
Failure to do so could prevent the heater from operating reliably (FIGURE 4).
