PRODUCT FEATURES

OPERATION

This heater is clean burning. It requires no outside venting. There is
no heat loss out a vent or up a chimney. Heat is generated by both
realistic fl ames and glowing coals. This heater is designed for vent-free
operation with fl ue damper closed. It has been tested and approved
to the ANSI Z21.11.2 standard for unvented heaters. State and local
codes in some areas prohibit the use of vent-free heaters. This heater
may also be operated as a vented decorative (ANSI Z21.60) product
by opening the fl ue damper.

AIR FOR COMBUSTION AND VENTILATION

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. Read the following instructions to ensure proper
fresh air for this and other fuel-burning appliances in
your home.

Today’s homes are built more energy effi cient than ever. New materials,
increased insulation and new construction methods help reduce heat
loss in homes. Homeowners weather strip and caulk around windows
and doors to keep the cold air out and the warm air in. During heating
months, Homeowners want their homes as airtight as possible.

While it is good to make your home energy effi cient, your home
needs to breathe. Fresh air must enter your home. All fuel-burning
appliances need fresh air for proper combustion and ventilation.

Exhaust fans, some fi replaces, clothes dryers and some fuel-burning
appliances draw air from the house to operate. You must provide ad­equate fresh air for these appliances. That will ensure proper venting
of vented fuel-burning appliances.

PROVIDING ADEQUATE VENTILATION

The following are excerpts from National Fuel Gas Code, ANSI Z223.1/
NFPA 54, Air for Combustion and Ventilation.

All spaces in homes fall into one of the three following ventilation
classifi cations:

1. Unusually Tight Construction

2. Unconfi ned Space

3. Confi ned Space

The information on pages 5-7 will help you classify your space and
provide adequate ventilation.

• hand-held thermostat remote
See Accessories, page 32.
The wall thermostat or hand-held thermostat may not be used where

vented decorative listing is required.

SAFETY DEVICE

This heater has a pilot with an Oxygen Depletion Sensing (ODS)
safety shutoff system. The ODS/pilot is a required feature for vent­free room heaters. The ODS/pilot shuts off the heater if there is not
enough fresh air.

ELECTRONIC IGNITION SYSTEM

This heater has an electronic igniter to light heater fuel supply.

Unusually Tight Construction

The air that leaks around doors and windows may provide enough
fresh air for combustion and ventilation. However, in buildings of
unusually tight construction, you must provide additional fresh air.

Unusually tight construction is defi ned as construction where:
a. walls and ceilings exposed to the outside atmosphere have a

continuous water vapor retarder with a rating of one perm (6 x

-11

10

kg per pa-sec-m2) 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 sole plates and fl oors, be­tween wall-ceiling joints, between wall panels, at penetrations
for plumbing, electrical and gas lines and at other openings.

If your home meets all three criteria above, you must provide ad­ditional fresh air. See Ventilation Air From Outdoors, page 7.

If your home does not meet all three criteria above, proceed to De-
termining Fresh-Air Flow For Heater Location, page 6.

Confi ned and Unconfi ned Space

The National Fuel Gas Code, ANSI Z223.1/NFPA54 allows two meth­ods for determining whether the space in which the heater is being
installed is confi ned or unconfi ned space. The standard method de­fi nes a confi ned space as a space whose volume is less than 50 cubic
feet per 1,000 Btu/hr (4.8 m
all appliances installed in that space and an unconfi ned space as a
space whose volume is not less than 50 cubic feet per 1,000 Btu/hr

3

(4.8 m

per 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 unconfi ned space.

Where the air infi ltration rate of a structure is known, the Known Air
Infi ltration Rate Method may be used. Follow The National Fuel Gas
Code, ANSI Z223.1/NFPA 54 to use this method to determine if the
space is confi ned or unconfi ned.

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

Determining if You Have a Confi ned or Unconfi ned Space Using
the Standard Method

Use this work sheet to determine if you have a confi ned or uncon­fi ned space.

Space: Includes the room in which you will install fi replace plus
any adjoining rooms with doorless passageways or ventilation grills
between the rooms.

1. Determine the volume of the space (length x width x height).
Length x Width x Height =__________cu. ft. (volume of space)
Example: Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling

height) = 2560 cu. ft. (volume of space)

If additional ventilation to adjoining room is supplied with grills

or openings, add the volume of these rooms to the total volume
of the space.

2. Multiply the space volume by 20 to determine the maximum Btu/Hr
the space can support.

_______ (volume of space) x 20 = (Maximum Btu/Hr the space

can support)
Example: 2560 cu. ft. (volume of space) x 20 = 51,200 (maximum

Btu/Hr the space can support)

3. Add the Btu/Hr of all fuel-burning appliances in the space.

Vent-free fi replace ________Btu/Hr
Gas water heater* ________Btu/Hr
Gas furnace ________Btu/Hr
Vented gas heater ________Btu/Hr
Gas fi replace logs ________Btu/Hr
Other gas appliances* __________ + Btu/Hr
Total =_______Btu/Hr
* Do not include direct-vent gas appliances. Direct-vent draws

combustion air from the outdoors and vents to the outdoors.

Example:
Gas water heater 40,000 Btu/Hr
Vent-free fi replace + 33,000 Btu/Hr
Total = 73,000 Btu/Hr

4. Compare the maximum Btu/Hr the space can support with the
actual amount of Btu/Hr used.

_____ Btu/Hr (maximum the space can support)
_____ Btu/Hr (actual amount used)
Example:51,200 Btu/Hr (maximum the space can support)
73,000 Btu/Hr (actual amount of Btu/Hr used)

The space in the above example is a confi ned space because the actual
Btu/Hr used is more than the maximum Btu/Hr the space can support.
You must provide additional fresh air. Your options are as follows:

A. Rework worksheet, adding the space of an adjoining room. If the

extra space provides an unconfi ned space, remove door to adjoin­ing room or add ventilation grills between rooms. See Ventilation

Air From Inside Building, page 6.

B. Vent room directly to the outdoors. See Ventilation Air From

Outdoors, page 7.

C. Install a lower Btu/Hr fi replace, if lower Btu/Hr size makes room

unconfi ned.

If the actual Btu/Hr used is less than the maximum Btu/Hr the space
can support, the space is an unconfi ned space. You will need no
additional fresh air ventilation.

WARNING: If the area in which the heater may
be operated does not meet the required volume for
indoor combustion air, combustion 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.

VENTILATION AIR
Ventilation Air From Inside Building

This fresh air would come from an adjoining unconfi ned space. When
ventilating to an adjoining unconfi ned space, you must provide two
permanent openings: one within 12" of the ceiling and one within
12" of the fl 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.

need a hood.

Determining Minimum Mantel Clearance

If you meet minimum clearance between mantel shelf and top of
fi replace opening, a hood is not required (see Figure 6).

Determining Minimum Mantel Clearance When Using a Hood

If minimum clearances in Figure 6, are not met, you must have a
hood. When using a hood there are still certain minimum mantel
clearances required. Follow minimum clearances shown in Figure

INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED
OPERATION

NOTE: When used as a vented heater, appliance must be installed only
in a solid-fuel-burning fi replace with a working fl ue and constructed
of noncombustible material.

For Massachusetts Residents Only: Installation of this gas log
set as a vented appliance in the Commonwealth of Massachusetts
requires the damper be permanently removed or welded in the fully
open position.

If your heater is a manually-controlled model, you may use this
heater as a vented product. There are three reasons for operating
your heater in the vented mode.

1. The fi replace does not meet the clearance to combustibles 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 to you, you must permanently
open chimney fl ue damper. You must install the damper clamp ac­cessory (to order, see Accessories, page 32). This will ensure vented
operation (see Figure 10). The damper clamp will keep damper open.
Installation instructions are included with clamp accessory.

ComfortFlame.US.com 900559-00 NC10

WARNING: You must secure this heater to fi re­place fl oor. If not, heater will move when you adjust
controls. Moving heater may cause a gas leak or
log misplacement.

WARNING: If installing in a sunken fi replace,
special care is needed. You must raise the fi replace
fl oor to allow access to heater control panel. This will
ensure adequate air fl ow and guard against sooting
and controls being damaged. Raise fi replace fl oor
with noncombustible material. Make sure material
is secure.

CAUTION: Do not pick up heater base assembly
by burners. This could damage heater. Only handle
base assembly by grates.

IMPORTANT: Make sure the heater burners are level. If
heater is not level, heater will not work properly.

Installation Items Needed

• hardware package (provided with heater)

• approved flexible gas hose and fittings (only provided with
TrueFlame™ burner system series) (if allowed by local codes)

• sealant (resistant to propane/LP gas, not provided)

• electric drill with 3/16” masonry drill bit

NOTE: Install optional receiver and hand-held remote control kit (see
Accessories, page 32) before installing gas log heater. See installation
instructions included with the kit.

1. Apply pipe joint sealant lightly to male threads of the 1/2 NPT

side of gas fi tting elbow (provided) and connect to inlet side of

INSTALLATION

Continued

Installation Items Needed

Before installing heater, make sure you have the items listed below.

• external regulator (supplied by installer)

• piping (check local codes)

• sealant (resistant to propane/LP gas)

• equipment shutoff valve *

• test gauge connection *

• sediment trap

• tee joint

• pipe wrench

• approved fl exible gas line with gas connector (if allowed by local
codes) (not provided)

* An equipment shutoff valve with 1/8" NPT tap is an acceptable al­ternative to test gauge connection. Purchase the optional equipment
shutoff valve from your dealer.

For propane/LP units, the installer must supply an external regulator.
The external regulator will reduce incoming gas pressure. You must
reduce incoming gas pressure to between 11" and 14" of water. 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 13. Pointing the vent down protects it from freezing
rain or sleet.

CAUTION: Use only new, black iron or steel
pipe. Internally-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 volume will occur.

Propane/LP
Supply Tank

External Regulator
with Vent Pointing
Down

IMPORTANT: Install equipment shutoff valve in an accessible loca­tion. The equipment shutoff valve is for turning on or shutting off
the gas to the appliance.

Check your building codes for any special requirements for locating
equipment shutoff valve to appliances.

Apply pipe joint sealant lightly to male NPT threads. This will prevent
excess sealant from going into pipe. Excess sealant in pipe could
result in clogged heater valves.

WARNING: Use pipe joint sealant that is resistant

to liquid petroleum (LP) gas.

We recommend that you install a sediment trap in supply line as
shown in Figure 14, page 12. Locate sediment trap where it is within
reach for cleaning. Install in piping system between fuel supply and
heater. Locate sediment trap where trapped matter is not likely to
freeze. A sediment trap traps moisture and contaminants. This keeps
them from going into heater controls. If sediment trap is not installed
or is installed wrong, heater may not run properly.

CAUTION: Avoid damage to gas control. Hold
gas fi tting with wrench when connecting it to gas
piping and/or fi ttings.

OPERATION

FOR YOUR SAFETY

READ BEFORE LIGHTING

WARNING: If you do not follow these instruc­tions exactly, a fi re or explosion may result causing
property damage, personal injury or loss of life.

A. This appliance has a pilot which must be lighted by hand. When

lighting the pilot, follow these instructions exactly.

B. BEFORE LIGHTING smell all around the appliance area for gas.

Be sure to smell next to the fl oor because some gas is heavier
than air and will settle on the fl oor.

WHAT TO DO IF YOU SMELL GAS

• Do not try to light any appliance.

• Do not touch any electric 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 fi re department.

C. Use only your hand to push in or turn the gas control knob. Never

use tools. If the knob will not push in or turn by hand, don’t try to
repair it, call a qualifi ed service technician or gas supplier. Force
or attempted repair may result in a fi re or explosion.

D. Do not use this appliance if any part has been under water. Imme-

diately call a qualifi ed service technician to inspect the appliance
and to replace any part of the control system and any gas control
which has been under water.

NOTE: Homeowners generally prefer to operate their heater with the
chimney damper closed. This will put all the heat into the room. However,
there may be times you will desire the full fl ames of the HI heat setting but
will fi nd the heat output excessive. You can open the chimney damper (if
you have one) fully or partially to release some of the heat.

INSPECTING BURNERS

Check pilot fl ame pattern and burner fl ame patterns often.

PILOT FLAME PATTERN

Figure 43 shows a correct pilot fl ame pattern. Figure 44 shows an
incorrect pilot fl ame pattern. The incorrect pilot fl ame is not touching
the thermocouple. This will cause the thermocouple to cool. When
the thermocouple cools, the heater will shut down.

If pilot fl ame pattern is incorrect, as shown in Figure 44

• turn heater off (see To Turn Off Gas to Appliance, page 21

• see Troubleshooting, page 24

NOTE: The pilot fl ame on natural gas units will have a slight curve,
but fl ame should be blue and have no yellow or orange color.

CLEANING AND MAINTENANCE

WARNING: Turn off heater and let cool before

cleaning.

CAUTION: You must keep control areas, burners and
circulating air passageways of heater clean. Inspect
these areas of heater before each use. Have heater
inspected yearly by a qualifi ed service person. Heater
may need more frequent cleaning due to excessive
lint from carpeting, pet hair, bedding material, etc.

WARNING: Failure to keep the primary air
opening(s) of the burner(s) clean may result in
sooting and property damage.

BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE

The primary air inlet holes allow the proper amount of air to mix with
the gas. This provides a clean burning fl ame. Keep these holes clear
of dust, dirt, lint and pet hair. Clean these air inlet holes prior to each
heating season. Blocked air holes will create soot. We recommend
that you clean the unit every three months during operation and have
heater inspected yearly by a qualifi ed service person.

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 PSI. Your local computer
store, hardware store or home center may carry compressed air in a
can. If using 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 off unit, including pilot. Allow unit to cool for at least thirty
minutes.

2. Inspect burner, pilot and primary air inlet holes on injector holder
for dust and dirt (see Figure 45).

3. Blow air through the ports/slots and holes in the burner.

4. Check injector holder located at end of 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.

Clean pilot assembly also. Additional cleaning may be needed for
proper pilot operation based on use/lack of use. A yellow tip on the
pilot fl ame may indicate dust and dirt in the pilot assembly. There is
a small pilot air inlet hole about from where the pilot fl ame comes
out of pilot assembly (see Figure 46). With unit off, lightly blow
air through air inlet hole. You may blow through a drinking straw if
compressed air is not available.

Holder

• If you remove logs for cleaning, refer to Installing Logs, Embers

and Volcanic stone, page 15, to properly replace logs.

• Replace log(s) if broken or chipped (dime-sized or larger).

MAIN BURNER

Periodically inspect all burner fl ame holes with heater running. All slotted
burner fl ame holes should be open with fl ame present. All round burner
fl ame holes should be open with a small blue fl ame present. Some burner
fl ame holes may become blocked by debris or rust, with no fl ame present.
If so, turn off heater and let cool. Remove blockage, blocked burner fl ame
holes will create soot.
