QUALIFIED INSTALLING AGENCY
Only a qualied agency should install and
replace gas piping, gas utilization equipment
or accessories, and repair and equipment ser-
vicing. The term “qualied agency” means any
individual, rm, corporation, or company that
either in person or through a representative
is engaged in and is responsible for:
a) Installing, testing, or replacing gas piping
or
b) Connecting, installing, testing, repairing,
or servicing equipment; that is experienced
in such work; that is familiar with all precau-
tions required; and that has complied with
all the requirement of the authority having
jurisdiction.
In areas that prohibit the use of vent-free
heaters, the log set has been tested and
approved to the ANSI Z21.60 standard for
Vented Decorative Logs. When used as a
vented log set refer to additional instructions
on page 11.
WATER VAPOR: A BY-PRODUCT OF
UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combus-
tion. An unvented room heater produces ap-
proximately one (1) ounce (30 mL) of water
for every 1,000 BTUs (0.3 KWs) of gas input
per hour. Unvented room heaters are recom-
mended as supplemental heat (a room) rather
than a primary heat source (an entire house).
In most supplemental heat applications, the
water vapor does not create a problem. In
most applications, the water vapor enhances
the low humidity atmosphere experienced
during cold weather.
The following steps will help ensure that water
vapor does not become a problem.
1. Be sure the heater is sized properly for the
application, including ample combustion
air and circulation air.
2. If high humidity is experienced, a dehu-
midier may be used to help lower the
water vapor content of the air.
3. Do not use an unvented room heater as
the primary heat source.
AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall
not be installed in a conned
space or unusually tight con-
struction unless provisions are
provided for adequate combus-
tion and ventilation air. Read the
following instructions to insure
proper fresh air for this and
other fuel-burning appliances
in your home.
Today’s homes are built more energy e󰀩cient
than ever. New materials, increased insulation
and new construction methods help reduce
heat loss in homes. Home owners weather
strip and caulk around windows and doors
to keep the cold air out and the warm air in.
During heating months, home owners want
their homes as airtight as possible.
While it is good to make your home energy
e󰀩cient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning ap-
pliances need fresh air for proper combustion
and ventilation.
Exhaust fans, replaces, clothes dryers and
fuel burning appliances draw air from the
house to operate. You must provide adequate
fresh air for these appliances. This will insure
proper venting of vented fuel-burning appli-
ances.
WARNING: This heater
shall not be installed in a room
or space unless the required
volume of indoor combustion
air is provided by the method
described in the National Fuel
Gas Code, ANSI Z223.1/NFPA
54, the International Fuel Gas
Code, or applicable local codes.

adjoining unconned space, you must provide
two permanent openings: one within 12" of the
ceiling and one within 12" of the oor on the
wall connecting the two spaces (see options
1 and 2, Figure 2). You can also remove door
into adjoining room (see option 3, Figure 2).
Follow the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, Air for Combustion and
Ventilation for required size of ventilation
grills or ducts.
Ventilation Air From Outdoors
WARNING: If the area in which the heater may be operated does
not meet the required volume for indoor combustion air, combus-
tion and ventilation air shall be provided by one of the methods
described in the National Fuel Gas Code, ANSI Z223.1/NFPA 54, the
International Fuel Gas Code, or applicable local codes.
Provide extra fresh air by using ventilation
grills or ducts. You must provide two perma-
nent openings: one within 12" of the ceiling
and one within 12" of the oor. Connect these
items directly to the outdoors or spaces open
to the outdoors. These spaces include attics
and crawl spaces. Follow the National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation for required size
of ventilation grills or ducts.
IMPORTANT: Do not provide openings
for inlet or outlet air into attic if attic has a
thermostat-controlled power vent. Heated air
entering the attic will activate the power vent.
Rework worksheet, adding the space of the
adjoining unconned space. The combined
spaces must have enough fresh air to supply
all appliances in both spaces.

INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED
OPERATION
When used as a vented heater, appliance
must be installed only in a solid-fuel burning
replace with a working ue constructed of
noncombustible material. You may use this
heater as a vented product. There are three
reasons for operating your heater as a vented
model:
1. The replace does not meet the clearance
requirements for vent-free operation.
2. State or local codes do not permit vent-
free operation.
3. You prefer vented operation.
If reasons number 1 or 2 above apply, you
must permanently open chimney ue damper.
You must install the damper clamp accessory
(not provided). This will insure vented opera-
tion (see Figure 10). The damper clamp will
keep damper open. Installation instructions
are included with clamp accessory.
See chart below for the minimum permanent
ue opening you must provide. Attach damper
clamp so the minimum permanent opening will
be maintained at all times.

CONNECTING TO GAS SUPPLY
CAUTION: For natural gas,
check your gas line pressure
before connecting heater to gas
line. Gas line pressure must be
no greater than 10.5" WC. If gas
line pressure is higher, heater
regulator damage could occur.
CAUTION: Avoid damage to
regulator. Hold gas regulator
with wrench when connecting
into gas piping and/or ttings.
CAUTION: Use pipe joint
sealant that is resistant to gas
(Propane or Natural Gas).
Before installing heater, make sure you have
the items listed below:
• external regulator for propane unit only
(supplied by installer)
• piping (check local codes)
• sealant (resistant to natural gas and pro-
pane gas)
• equipment shuto󰀨 valve*
• test gauge connection*
• sediment trap
• tee joint
• pipe wrench
• exible gas hose (check local codes)
* A CSA design-certied equipment shuto󰀨
valve with 1/8" NPT tap is an acceptable al-
ternative to test gauge connection. Purchase
the optional CSA design certied equipment
shuto󰀨 valve from your dealer.
WARNING: A qualied ser-
vice technician must connect
heater to gas supply. Follow all
local codes.
WARNING: This appliance
requires a 3/8" NPT (National
Pipe Thread) inlet connection to
the pressure regulator.
WARNING: Do not over-
tighten gas connections.
WARNING: For natural gas,
Never connect heater to private
(non-utility) gas wells. This gas
is commonly known as wellhead
gas.
CAUTION: For propane gas,
never connect heater directly
to the gas supply. This heater
requires an external regulator
(not supplied). Install the exter-
nal regulator between the heater
and propane supply. Gas sup-
plier provides external regulator
for natural gas. The installer
provides the external regulator
for propane gas.
CAUTION: Use only new,
black iron or steel pipe. Inter-
nally tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of
1/2" diameter or greater to allow
proper gas volume to heater. If
pipe is too small, undue loss of
pressure will occur.

Figure 14 - Gas Connection
Figure 13 - Attaching Flexible Gas Hose
to Heater Gas Regulator
* Purchase the optional CSA design-certied equipment

Typical Inlet Pipe Diameters
Use 1/2" black iron pipe or greater. Installa-
tion must include an equipment shuto󰀨 valve,
union, and plugged 1/8" NPT tap. Locate
NPT tap within reach for test gauge hook up.
NPT tap must be upstream from heater (see
Figure 14).
IMPORTANT: Install an equipment shuto
valve in an accessible location. The equip-
ment shuto valve is for turning on or shutting
o the gas to the appliance.
For propane installations, apply pipe joint
sealant lightly to male threads. This will
prevent excess sealant from going into pipe.
Excess sealant in pipe could result in clogged
heater valves.
The installer must supply an external regula-
tor. The external regulator will reduce incom-
ing gas pressure. You must reduce incoming
gas pressure to between 11" WC and 14" WC.
If you do not reduce incoming gas pressure,
heater regulator damage could occur. Install
external regulator with the vent pointing down
as shown in Figure 15. Pointing the vent down
protects it from freezing rain or sleet.

OPERATION
Avoid any drafts that alter burner ame
patterns. Do not allow fans to blow directly
into the replace. Do not place a blower inside
the burn area of the rebox. Ceiling fans may
create drafts that alter ame patterns. Sooting
and improper burning will result.
During manufacturing, fabricating and ship-
ping, various components of this appliance
are treated with certain oils, lms or bonding
agents. These chemicals are not harmful but
may produce annoying smoke and smells as
they are burned o󰀨 during the initial operation
of the appliance, possibly causing headaches
or eye or lung irritation. This is a normal and
temporary occurrence.
The initial break-in operation should last two
to three hours with the burner at the high-
est setting. Provide maximum ventilation by
opening windows or doors to allow odors to
dissipate. Any odors remaining after this initial
break-in will be slight and will disappear with
continued use.
This appliance must not be used with glass
doors in the closed position. This can lead
to pilot outages and severe sooting outside
the replace.
Always operate heater with glass doors fully
open.

INSPECTING BURNERS
IMPORTANT: Owner’s should check pilot ame pattern and burner ame pattern often.
Incorrect ame patterns indicate the need for cleaning (see Care and Maintenance,
page 20) or service.
WARNING: Only a qualied service person should service and
repair heater. This includes maintenance requiring replacement or
alteration of components.
PILOT FLAME PATTERN
Figure 22 shows a correct pilot ame pattern.
Figure 23 shows an incorrect pilot ame pat-
tern. The incorrect pilot ame is not touching
the thermocouple. This will cause the ther-
mocouple to cool, which shuts the heater o󰀨.
If pilot ame pattern is incorrect, as shown
in Figure 23
• turn heater o󰀨 (see To Turn O Gas to Ap-
pliance, page 18)
• see Troubleshooting pages 21 through 23.
WARNING: If yellow tipping
occurs, your heater could pro-
duce increased levels of carbon
monoxide. If the burner ame
pattern shows yellow tipping,
follow instructions at bottom of
this page.
Notice: Do not mistake orange ames with
yellow tipping. Dirt or other ne particles enter
the heater and burn causing brief patches of
orange ame.

Use a vacuum cleaner, pressurized air, or a
small, soft bristled brush to clean.
A yellow tip on the pilot ame indicates dust
and dirt in the pilot assembly. There is a small
pilot air inlet hole about 2" from where the
pilot ame comes out of the pilot assembly
(see Figure 27). With the unit o󰀨, lightly blow
air through the air inlet hole. You may blow
through a drinking straw if compressed air is
not available. Figure 27 - Pilot Inlet Air Hole

We recommend that you clean the unit ev-
ery 2,500 hours of operation or every three
months. We also recommend that you keep
the burner tube and pilot assembly clean
and free of dust and dirt. To clean these
parts we recommend using compressed air
no greater than 30 PSl. Your local computer
store, hardware store, or home center may
carry compressed air in a can. You can use
a vacuum cleaner in the blow position. If us-
ing compressed air in a can, please follow
the directions on the can. If you don’t follow
directions on the can, you could damage the
pilot assembly.
1. Shut o󰀨 the unit, including the pilot. Allow
the unit to cool for at least thirty minutes.
2. Inspect burner, pilot and primary air inlet
holes on injector for dust and dirt (see
Figure 26).
3. Blow air through the ports/slots and holes
in the burner. Also clean the pilot assembly.
4. Check the injector holder located at the
end of the burner tube again. Remove any
large particles of dust, dirt, lint, or pet hair
with a soft cloth or vacuum cleaner nozzle.
5. Blow air into the primary air holes on the
injector holder.
6. In case any large clumps of dust have
now been pushed into the burner. Repeat
steps 3 and 4.
CARE AND MAINTENANCE
WARNING: Turn o󰀨 heater and let cool before servicing.
CAUTION: You must keep control areas, burner, and circulating
air passageways of heater clean. Inspect these areas of heater before
each use. Have heater inspected yearly by a qualied service techni-
cian. Heater may need more frequent cleaning due to excessive lint
from carpeting, bedding material, pet hair, etc.
WARNING: Failure to keep the primary air opening(s) of the
burner(s) clean may result in sooting and property damage.
MAIN BURNER
Periodically inspect all burner ame holes with
the heater running. All slotted burner ame
holes should be open with yellow ame pres-
ent. All round burner ame holes should be
open with a small blue ame present. Some
burner ame holes may become blocked by
debris or rust, with no ame present. If so,
turn o󰀨 the heater and let it cool, and remove
blockage or replace burner. Blocked burner
ame holes will create soot.
