Today’s homes are built more energy efficient 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.
Quincy, MA 02269
Note: Where listed vented decorative logs are required, thermostat
models are not permitted.
UNPACKING
While it is good to make your home energy efficient, your home
needs to breathe. Fresh air must enter your home. All fuel-burning
appliances need fresh air for proper combustion and ventilation.
CAUTION: Do not remove the data plates from the
grate assembly. The data plates contain important
product and safety information.

air for these appliances. This will insure proper venting of vented
fuel-burning appliances.
1. Remove logs and heater base assembly from carton. Note: Do
not pick up heater base assembly by burners. This could dam-
age heater. Always handle base assembly by grate.

All spaces in homes fall into one of the three following ventilation
classifications:
PRODUCT FEATURES
OPERATION
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
This heater is clean burning. It requires no outside venting. There is
noheatlossoutaventorupachimney.Heatisgeneratedbyrealistic,
dancing yellow flames. This heater is designed for vent-free opera-
tion with flue damper closed. It has been tested and approved to
ANSI Z21.11.2 standard for unvented heaters. State and local codes
in some areas prohibit the use of vent-free heaters. Non-thermostat
models may also be operated as a vented decorative (ANSI Z21.60)
product by opening flue damper.
The information on pages 4 through 6 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.
SAFETY PILOT
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 ignitor. This system requires no matches,
batteries, or other sources to light heater.

Confined Space and Unconfined Space
The National Fuel Gas Code ANSI Z223.1/NFPA 54 defines a
confined space as a space whose volume is less than 50 cubic feet
per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating
of all appliances installed in that space and an unconfined space as
aspacewhosevolumeisnotlessthan50cubicfeetper1,000Btuper
hour (4.8 m3 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 unconfined space.
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 of Btu/Hr used)
Example: 51,200 Btu/Hr (maximum the space can support)
71,500 Btu/Hr (actual amount of Btu/Hr used)
The space in the above example is a confined 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:
* Adjoining rooms are communicating only if there are doorless
passageways or ventilation grills between them.
DETERMINING FRESH-AIR FLOW FOR
HEATER LOCATION
A. Rework worksheet, adding the space of an adjoining room. If the
extra space provides an unconfined space, remove door to adjoining
room or add ventilation grills between rooms. See Ventilation Air From
Inside Building, page 6.
Determining if You Have a Confined or
Unconfined Space
B. Vent room directly to the outdoors. See Ventilation Air From Out-
doors, page 6.
Use this work sheet to determine if you have a confined or unconfined space.
C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room unconfined.
Space:Includestheroominwhichyouwillinstallheaterplusanyadjoining
If the actual Btu/Hr used is less than the maximum Btu/Hr the space can
support, the space is an unconfined space. You will need no additional fresh
air ventilation.
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)
WARNING: If the area in which the heater may be
operated is smaller than that defined as an uncon-
fined space or if the building is of unusually tight
construction,provideadequatecombustionandven-
tilation air by one of the methods described in the
National Fuel Gas Code, ANSI Z223.1/NFPA 54 Sec-
tion 5.3 or applicable local codes.
If additional ventilation to adjoining room is supplied with grills or open-
ings, add the volume of these rooms to the total volume of the space.

CAUTION:Donotremovethedataplatesattached
to the heater base assembly. The data plates contain
important warranty and safety information.
Note: When used as a vented heater, appliance must be installed
only in a solid-fuel burning fireplace with a working flue and
constructed of noncombustible material.
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.
WARNING: You must secure this heater to fire-
place floor. If not, heater will move when you adjust
controls. Moving heater may cause a gas leak.
1. The fireplace does not meet the clearance to combustibles re-
quirements for vent-free operation.
2. State or local codes do not permit vent-free operation.
3. You prefer vented operation.
WARNING:Ifinstallinginasunkenfireplace,special
care is needed. You must raise the fireplace floor to
allow access to heater control panel. This will insure
adequate air flow and guard against sooting and con-
trols being damaged. Raise fireplace floor with non-
combustible material. Make sure material is secure.
If reasons number 1 or 2 above apply to you, you must permanently
open chimney flue damper. You must install the damper clamp
accessory(toorder,seeAccessories,page32).Thiswillinsurevented
operation (see Figure 10). The damper clamp will keep damper open.
Installation instructions are included with clamp accessory.
See chart below for minimum permanent flue opening you must
provide. Attach damper clamp so the minimum permanent flue
opening will be maintained at all times.

locations in mortar joint of bricks.
WARNING: For natural gas units, never connect
heater to private (non-utility) gas wells. This gas is
commonly known as wellhead gas.
8. Remove heater base from fireplace.
9. Drill holes at marked locations using 3/16" drill bit.
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 *
10. Attach base assembly to fireplace floor using two masonry
screws (in hardware package) (see Figure 12).

Installation must include a 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 Figure 14).
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections
forleaksafterinstallingorservicing. Correctallleaks
at once.
IMPORTANT: Install equipment shutoff valve in an accessible
location. The main gas valve is for turning on or shutting off the gas
to the appliance.
Checkyourbuildingcodesforanyspecialrequirementsforlocating
equipment shutoff valve to fireplaces.
WARNING: Never use an open flame to check for
a leak. Apply a commercial leak detection solution to
all joints. Bubbles forming show a leak. Correct all
leaks at once.
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.
CAUTION: For propane/LP units, make sure ex-
ternal regulator has been installed between propane/
LPsupplyandheater. SeeguidelinesunderConnect-
ing to Gas Supply, page 11.
WARNING: Use pipe joint sealant that is resistant
to liquid petroleum (LP) gas.
We recommend that you install sediment trap in supply line as
showninFigure14.Locatesedimenttrapwhereitiswithinreachfor
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.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1. Disconnect appliance with its appliance main gas valve (control
valve) and equipment shutoff valve from gas supply piping. Pres-
sures in excess of 1/2 psig will damage heater regulator.
2. Cap off open end of gas pipe where equipment shutoff valve
was connected.
CAUTION: Avoid damage to regulator. Hold gas
regulator with wrench when connecting it to gas
piping and/or fittings.
3. Pressurize supply piping system by either opening propane/LP
supply tank valve for propane/LP gas or opening main gas valve
located on or near gas meter for natural gas, or using com-
pressed air.

Figure 29 shows a correct pilot flame pattern. Figure 30 shows an
incorrect pilot flame pattern. The incorrect pilot flame is not
touching the thermocouple. This will cause the thermocouple to
cool. When the thermocouple cools, the heater will shut down.
CAUTION: You must keep control areas, burner,
and circulating air passageways of heater clean. In-
spect these areas of heater before each use. Have
heater inspected yearly by a qualified service person.

Note: Do not remove the screw. Make sure you tighten the
screw after removing the thermostat sensing bulb.
IMPORTANT: Do not force or bend the thermostat sensing
bulb or capillary.
3. The thermostat sensing bulb may be located to the lower right
front side of fireplace. Determine location of sensing bulb, but
do not mount sensing bulb until step 5. If you have a masonry
fireplace, see Figure 36 for location. If you have a factory-
built metal fireplace, see Figure 37 for location. If your fire-
place has glass doors, position sensing bulb directly behind
door gap on right bottom side (see Figure 38).

4. The mounting clip must be a minimum of 3" from bottom of
fireplace to prevent crimping of capillary. Once you have de-
cided on a location, clean the area thoroughly. Remove the pa-
per backing from the adhesive on back of mounting clip. Press
the clip into the new location so that the thermostat sensing bulb
will be positioned vertically with the capillary at the bottom
(see Figure 39). Slide the thermostat sensing bulb into the clip.
