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.
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/NFP A 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 apply
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 fuelburning appliances.
PROVIDING ADEQUA TE

SAFETY DEVICE
This heater has a pilot with an Oxygen Depletion Sensing (ODS) safety shutoff system. The
ODS/pilot is a required feature for vent-free
room heaters. The ODS/pilot shuts off the
heater if there is not enough fresh air.
PIEZO IGNITION SYSTEM
This heater has a piezo igniter. This system requires no matches, batteries or other sources
to light heater.
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 6 through 8 will
help you classify your space and provide
adequate ventilation.
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 out-
side atmosphere have a continuous
water vapor retarder with a rating of
one perm (6 x 10
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 8.

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
3
feet per 1,000 Btu per hour (4.8 m
per kw)
of the aggregate input rating of all appliances
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/HrGas water heater* __________Btu/Hr
Gas furnace __________ Btu/Hr
Vented gas heater __________Btu/Hr
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 per hour (4.8
3
per kw) of the aggregate input rating of
m
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.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation
grills between them.
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 heater 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 = (Maxi-
mum Btu/Hr the space can support)

Example: 51,200 Btu/Hr (maximum the
73,000 Btu/Hr (actual amount of
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 adjoin-
ing room or add ventilation grills between
rooms. See Ventilation Air From Inside
Building, Page 8.
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors, Page 8.
C. Install a lower Btu/Hr appliance, if lower Btu/
Hr size makes room unconfi ned.
If the actual Btu/Hr used is less than the maxi-
mum Btu/Hr the space can support, the space is
an unconfi ned space. You will need no additional
fresh air ventilation.

CONNECTING TO GAS SUPPLY
WARNING: This appliance
requires a 1/2" NPT (National
Pipe Thread) inlet connection
to the pressure regulator.
WARNING: A qualifi ed ser-
vice person must connect appliance to gas supply. Follow
all local codes.
CAUTION: Never connect
propane/LP fi replace directly to
the propane/LP supply. This appliance requires an external regulator (not supplied). Install the
external regulator between the
heater and propane/LP supply.
WARNING: Never connect
natural gas appliance to private
(non-utility) gas wells. This
gas is commonly known as
wellhead gas.
with the vent pointing down as shown in
Figure 12. 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.

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
* A 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 1 1" and 14" of water. If you do not reduce incoming gas pressure, heater regulator
damage could occur. Install external regulator
ComfortFlame.US.com
Installation must include an equipment shutoff
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
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 fi replaces.
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 13. 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 .

INSPECTING BURNERS
Check pilot fl ame pattern and burner fl ame
patterns often.
PILOT FLAME PATTERN
Figure 22 shows a correct pilot fl ame pattern.
Figure 23 shows an incorrect pilot fl ame pat-
tern. 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 23.
• turn heater off (see To Turn Off Gas to Ap-
pliance, Page 19)
• see Troubleshooting, Page 23
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.
BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes
in the fi tting at the burner entrance. These
holes may become blocked with dust or lint.
Periodically inspect these holes for any blockage and clean if needed. Blocked air holes
will create soot.

MAIN BURNER
Periodically inspect all burner fl ame holes with
the heater running. All slotted burner fl ame
holes should be open with yellow fl ame pres-
ent. 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.
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 ORIFICE 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.

CLEANING AND MAINTENANCE
Continued
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 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 orifi ce holder for dust and dirt
(see Figures 24 and 25).

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
orifi ce holder .
6. In case any large clumps of dust have now
been pushed into the burner repeat steps
3 and 4.
Clean the pilot assembly also. A yellow tip
on the pilot fl ame indicates dust and dirt in
the pilot assembly. There is a small pilot air
inlet hole about two inches from where the
pilot fl ame comes out of the pilot assembly (see Figure 25). With the unit off, lightly blow
air through the air inlet hole. You may blow
through a drinking straw if compressed air is
not available.
