WATER VAPOR:ABY-PRODUCT OF UNVENTED
ROOM HEATERS
Water vapor is a by-product of gas combustion. An
unvented room heaterproduces approximately one (1)
ounce (30ml) of water for every 1,000 BTU's (.3KW's)
of gas input per hour. Refer to page 11.
This appliance may be installed in an aftermarket,
permanently located, manufactured (mobile) home,
where not prohibited by local codes.
This appliance is only for use with the type of gas
indicated on the rating plate. This appliance is not
convertible for use with other gases.

When used without adequate combustion and ventilation air,
heater may give off CARBON MONOXIDE, an odorless, poi-
sonous gas.
Do not install heater until all necessary provisions are
made for combustion and ventilation air. Consult the writ-
ten instructions provided with the heater for information
concerning combustion and ventilation air. In the absence
of instructions, refer to the National Fuel Gas Code,ANSI
Z223.1/NFPA 54, Air for Combustion and Ventilation, or
applicable local codes.
This heater is equipped with a PILOT LIGHT SAFETY SYS-
TEM designed to turn off the heater if not enough fresh air
is available.
DO NOT TAMPER WITH PILOT LIGHT SAFETY
SYSTEM!
If heater shuts off, do not relight until you provide fresh air.
If heater keeps shutting off, have it serviced. Keep burner and
control compartment clean.
CARBON MONOXIDE POISONING MAY LEAD TO
DEATH.

The pilot light safety system senses the depletion of oxygen at its
location. If this heater is installed in a structure having a high
vertical dimension, the possibility exists that the oxygen supply
at the higher levels will be less than that at the heater. In this type
of application, a fan to circulate the structure air will minimize
this effect. The use of this fan will also improve the comfort level
in the structure. When a fan is used to circulate air, it should be

can smell the odorant in propane. Smoking can decrease your
ability to smell. Being around an odor for a time can affect your
sensitivity or ability to detect that odor. Sometimes other odors
in the area mask the gas odor. People may not smell the gas odor
or their minds are on something else. Thinking about smelling a
gas odor can make it easier to smell.
The odorant in LP-gas is colorless, and it can fade under some
circumstances. For example, if there is an underground leak, the
movement of the gas through soil can lter the odorant. Odorants
in LP-Gas also are subject to oxidation. This fading can occur if
there is rust inside the storage tank or in iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into walls,
masonry and other materials and fabrics in a room. That will take
some of the odorant out of the gas, reducing its odor intensity.
LP-Gas may stratify in a closed area, and the odor intensity could
vary at different levels. Since it is heavier than air, there may be
more odor at lower levels. Always be sensitive to the slightest gas
odor. If you detect any odor, treat it as a serious leak. Immediately
go into action as instructed earlier.

and explosions. In its natural state, propane is odorless and
colorless. You may not know all the following safety precau-
tions which can protect both you and your family from an
accident. Read them carefully now, then review them point
by point with the members of your household. Someday when
there may not be a minute to lose, everyone's safety will depend
on knowing exactly what to do. If, after reading the following
information, you feel you still need more information, please
contact your gas supplier.
• Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it
to nd out what the propane odor smells like. If you suspect
that your LP-Gas has a weak or abnormal odor, call your
LP-Gas Dealer.
• If you are not qualied, do not light pilot lights, perform
service, or make adjustments to appliances on the LP-Gas
system. If you are qualied, consciously think about the odor
of LP-Gas prior to and while lighting pilot lights or perform-
ing service or making adjustments.
• Sometimes a basement or a closed-up house has a musty
smell that can cover up the LP-Gas odor. Do not try to light
pilot lights, perform service, or make adjustments in an area
where the conditions are such that you may not detect the
odor if there has been a leak of LP-Gas.
• Odor fade, due to oxidation by rust or adsorption on walls of
new cylinders and tanks, is possible. Therefore, people should
be particularly alert and careful when new tanks or cylinders
are placed in service. Odor fade can occur in new tanks, or
reinstalled old tanks, if they are lled and allowed to set too
long before relling. Cylinders and tanks which have been
out of service for a time may develop internal rust which will
cause odor fade. If such conditions are suspected to exist, a
periodic sniff test of the gas is advisable. If you have any
question about the gas odor, call your LP-gas dealer. A
periodic sniff test of the LP-gas is a good safety measure
under any condition.
• If, at any time, you do not smell the LP-Gas odorant and you
think you should, assume you have a leak. Then take the same
immediate action recommended above for the occasion when
you do detect the odorized LP-Gas.
• If you experience a complete "gas out," (the container is un-
der no vapor pressure), turn the tank valve off immediately.
If the container valve is left on, the container may draw in
some air through openings such as pilot light orices. If this
occurs, some new internal rusting could occur. If the valve is
left open, then treat the container as a new tank. Always be
sure your container is under vapor pressure by turning it off
at the container before it goes completely empty or having it
relled before it is completely empty.
• Do not operate electric switches, light matches, use your
phone. Do not do anything that could ignite the gas.
• Get everyone out of the building, vehicle, trailer, or area. Do
that IMMEDIATELY.
• Close all gas tank or cylinder supply valves.
• LP-Gas is heavier than air and may settle in low areas such
as basements. When you have reason to suspect a gas leak,
keep out of basements and other low areas. Stay out until
reghters declare them to be safe.
• Use your neighbor's phone and call a trained LP-Gas service
person and the re department. Even though you may not
continue to smell gas, do not turn on the gas again. Do not
re-enter the building, vehicle, trailer, or area.
• Finally, let the service man and reghters check for escaped
gas. Have them air out the area before you return. Properly
trained LP-Gas service people should repair the leak, then
check and relight the gas appliance for you.
SOME POINTS TO REMEMBER
NO ODOR DETECTED - ODOR FADE
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
That's your signal to go into immediate action!

Proper Log Placement
Log placement is critical to proper burner performance. Logs must
be correctly positioned onto the burner. The photos in this manual
show the proper pinned position for logs on this set. Owners need
to be shown proper log placement and instructed not to move the
logs.
Logs must t rmly onto the burner when positioned as shown in
the photos. Malformed logs or logs with sloppy pin holes must be
replaced.
Proper Placement of Rock Wool and Decorative Lava Rock
Rock wool can be added to burners for a glowing ember effect.
It must be positioned only on the front portion of the burner. The
photos in this manual show the proper placement of rock wool.
Decorative lava rock or small wood pieces should never be placed
on the burner. These items are only for placement on the oor of
the replace or rebox.

For proper burner operation and ame appearance, the ow of
primary air into the venturi tube, located on the rear of the burner,
must not be reduced. This ow of air is reduced if dirt, lint or
other obstructions build-up around or inside the venturi. Any
obstruction in the venturi tube area must be removed. The ow of
air into the venturi is also reduced if the gas orice isn’t centered
in the venturi inlet and/or is not aligned with the venturi. Any
misalignment of the burner orice may be corrected by bending
the shutter cap holding the orice to the inlet of the venturi tube.
Ceiling Fans, Portable Fans or Logs Installed Near Cold Air
Returns
Ceiling fans or oscillating oor type fans need to be monitored
during the operation of vent-free logs. If the air blows directly
into the ame causing it to impinge on the log set, or rebox, it
should be turned off or redirected. Ceiling fans could be reversed
to possibly eliminate ame impingement, and the oor fan could
be redirected. Upon installation, be aware of any cold air returns
or vents in the proximity of the log set. Any draft created around
a vent-free log set can cause the ame to impinge on the log and
create a sooting situation.
WARNING: Do not allow fans to blow directly into the replace.
Avoid any drafts that alter burner ame patterns.
WARNING: Do not use a blower insert, heat exchanger insert or
other accessory not approved for use with this heater.
Candles
Avoid the use of scented or decorative candles while the log set
is in operation. Candles produce a residue in the air that creates a
soot like substance. Burning candles while the log set is operating
magnies the problem. It should be noted that candles, in general,
produce soot. The amount of time burned and the quantity of
candles burned will determine the amount of soot produced and
deposited.
Make Owners Aware of Proper Log Set Operation
Properly installed and properly maintained log sets do not deposit
soot on the logs. If users see soot appear on a log, call for service.
Do not continue to operate the log set.

750 Millivolt System
When you ignite the pilot, the thermocouple produces millivolts
(electrical current) which energizes the magnet in the gas valve.
After 30 seconds to 1 minute time period you can release the gas
control knob and the pilot will stay ON. Allow your pilot ame to
operate an additional one (1) to two (2) minutes before you turn the
gas control knob from the PILOT position to the ON position. This
time period allows the millivolts (electrical energy) to build-up to
a sufcient level allowing the gas control to operate properly.

INSTALLATION IN A FIREPLACE
1. Before beginning, remove door and log package from unit.
Also check to make sure there is no hidden damage to the
unit. Take a minute and plan out the gas and electrical route.
It is best to start with the gas line rst, followed by the electri-
cal supply requirements.
2. Minimum replace opening requirements are shown in
Figure 2 of this installation manual. The rebrick (refrac-
tory), glass doors, screen rails, screen mesh and log grates
can be removed from a factory built replace in order to gain
minimum gas insert opening requirements prior to installing
the gas replace insert.
3. This insert requires no hearth extensions. Combustible ma-
terial on the oor may be installed up to the insert. Do not
obstruct the lower louver of the insert. The original replace
cannot be returned to solid fuel in this condition.
4. The metal oor of the solid fuel rebox may be removed to
facilitate the installation of the insert. The side walls and top
structure of the rebox may not be altered with the exception
of removable bafes and dampers. Smoke shields, shelves
and bafes may be removed if attached with mechanical fas-
teners. The original replace cannot be returned to solid fuel
in this condition.
5. The insert surround is tested and approved with this gas insert
and may cover existing air circulation vents or grills on the
solid fuel replace it is installed into. If the surround does
not cover the entire ventilation grill surface, the exposed grill
area should be left open.

the surround panel kit.
Ensure there are no obstructions to side air passages of
decorative trim once installed on insert.
Positioning, Leveling and Securing Insert
1. Place the insert into position
Note: The front anges of the insert (without surround panels)
should be set at approximately 1" in front of the face of
the replace.
2. Level the insert from side to side and front to back.
3. If necessary, use the leveling bolts included in the instruction
pack. Screw the legs into the nuts installed in the bottom of
the insert. Turn legs in until insert is level.
NOTE: The best way to access the leveling bolt locations is
to remove the burner and rebox bottom.

In planning the installation for the replace, it is necessary to
determine where the unit is to be installed and whether optional
accessories are desired. Gas supply piping should also be planned
at this time.
The replace can be mounted on any of these surfaces:
1. A at hard combustible or non-combustible surface.
2. A raised platform of combustible or non-combustible
material.
3. Four (4) corners of the replace so contact is made on all four
perimeter edges on the bottom of the unit.
(Example: Four (4) concrete masonry blocks.)
If the replace is installed directly on carpeting, tile or other
combustible material other than wood ooring, it should be installed
on a metal or wood panel extending the full width and depth of
the unit.
At this point, you should have decided what components to include
in your installation, and where the replace is to be located. If this
has not been done, stop and consult your dealer for assistance with
this planning.
BUILT-IN FIREPLACE INSTALLATION
This unit is designed to be installed in a zero-clearance enclosure.
This means the combustible material can come in contact with
the rebox.
Built-In Fireplace Installation
Built-in installation of this replace involves installing the
replace into a framed-in enclosure. This makes the front of
the replace ush with a wall. If installing a mantel above the
replace, you must follow the clearances shown in Figures 9 and
10. Follow the instructions below to install the replace in this
manner.
Frame in rough opening. Use dimensions show in Figure 3 for a
conventional rough opening. Use dimensions shown in Figure 4
for corner rough opening. Be sure to provide gas line for replace
and electrical power for optional blower assembly.
1. Gas line connections must be made at this time. When
facing the appliance, the gas supply will enter on the right-
hand side. See "Gas Supply" page 13.
2. Insert replace into enclosure.
3. Level rebox. See "Positioning, Leveling and Securing In-
sert" on Page 8.
4. Finished wall surface will be ush to the leading edge of re-
place top and sides.
5. If used, the surround panel assembly is installed after the re-
place has been installed with all the gas and electrical connec-
tion completed. See Page 17. Refer to instructions included
with the surround panel kit.
6. Installation of built-in replace is completed.

Water vapor is a by-product of gas combustion. An unvented room
heater produces approximately one (1) ounce (30ml) of water for
every 1,000 BTU's (.3KW's) of gas input per hour.
Unvented room heaters are recommended 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 insure 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 dehumidi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.
This heater shall not be installed in a conned space or unusually
tight construction unless provisions are provided for adequate
combustion and ventilation air.
The National Fuel Gas Code, ANSI Z223.1 denes a conned 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 unconned space as a space whose
volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8m3
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 unconned space.
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.

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 16 ft. (length) x 10 ft. (width) x 8 ft. (ceiling
height) = 1,280 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. Divide the space volume by 50 cubic feet to determine the
maximum BTU/Hr the space can support.
(volume of space) ÷ 50 cu. ft. = (maximum
BTU/Hr the space can support)
Example: 1,280 cu. ft. (volume of space) ÷ 50 cu. ft. = 25.6 or
25,600 (maximum BTU/Hr the space can support)
3. Add the BTU/Hr of all fuel burning appliances in the space.
Vent-free heater BTU/Hr
Gas water heater BTU/Hr
Gas furnace BTU/Hr
Vented gas heater BTU/Hr
Gas replace logs BTU/Hr
Other gas appliances* + BTU/Hr
Total = BTU/Hr
Example: Vented gas heater 20,000 BTU/Hr
Vent-free heater + 18,000 BTU/Hr
Total = 38,000 BTU/Hr
*Do not include direct-vent gas appliances. Direct vent draws
combustion air from the outdoors and vents to the outdoors.
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:
25,600 BTU/Hr (maximum the space can support)
38,000 BTU/Hr (actual amount of BTU/Hr used)
Warning: If the area in which the heater may be operated is smaller
than that dened as an unconned 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/NFPA 54, Air for Combustion and
Ventilation, or applicable local codes.

The space in the above example is a con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 unconned space, remove door to
adjoining room or add ventilation grills between rooms. See
Ventilation Air From Inside Building.
B. Vent room directly to the outdoors. See Ventilation Air From
Outdoors.
C. Install a lower BTU/Hr heater, if lower BTU/Hr size makes
room unconned.
If the actual BTU/Hr used is less than the maximum BTU/Hr the
space can support, the space is an unconned space. You will need
no additional fresh air ventilation.

This fresh air would come from an adjoining unconned space.
When ventilating to an 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 5). You can also remove door
into adjoining room (see option 3, Figure 5). Each ventilation grill
or opening shall have a minimum free area of one square inch per
1,000 BTUH of the total input rating of the gas equipment in the
conned space.

enough fresh air to supply all appliances in both spaces.
Ventilation Air From Outdoors (Figure 6)
Provide extra fresh air by using ventilation grills or ducts. You must
provide two permanent openings: one within 12" of the ceiling
and one with 12" of the oor. Connect these items directly to the
outdoors or spaces open to the outdoors. These spaces include
attics and crawl spaces. In most cases for direct communication
with the outdoors or direct communication through a vertical duct
a free area opening of one square inch per 4,000 BTU/Hr of heater
input rating for each grill. If a horizontal duct is used, a grill free
area or duct opening shall have a free area opening of one square
inch per 2,000 BTU/Hr for each grill. Follow the National Fuel
Code ANSI Z223.1/NFPA54, 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.

The gas pipeline can be brought in through the right or left side of
the appliance. The insert has a Flexline with shutoff valve located
on the right side when facing the unit. See Figures 7 and 8. Consult
the current National Fuel Gas Code,ANSI Z223.1 CAN/CGA-B149
(.1 or .2) installation code.
Installing the Main Gas Cock
Each appliance should have its own manual gas cock.
A manual main gas cock should be located in the vicinity of the
unit. Where none exists, or where its size or location is not ad-
equate, contact your local authorized installer for installation or
relocation.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liqueed petroleum gases. The gas lines must be
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.

NOTE: The millivolt gas controls are equipped with a captured
screw type pressure test point, therefore it is not necessary to provide
a 1/8" test point up stream of the control.
When using copper or ex connector use only approved ttings.
The appliance and it’s individual shut off valve must be disconnected
from supply piping system during any pressure testing of that system
at test pressures in excess of 1/2 psig (3.5kPa).
The appliance must be isolated from the gas supply piping system
by closing its individual manual shut off valve during any pressure
testing of the gas supply piping system at test pressures equal to or
less than 1/2 psig (3.5kPa).
Attention! If one of the procedures results in pressures in excess
of 1/2 psig (14" w.c.) (3.5 kPa) on the replace gas valve, it will
result in a hazardous condition.
Note: Never use plastic pipe. Check to conrm whether your
local codes allow copper tubing or galvanized.
Note: Since some municipalities have additional local codes, it is
always best to consult your local authority and installation code.
The use of the following gas connectors is recommended:
— ANSZ21.24ApplianceConnectors ofCorrugatedMetalTubing
and Fittings.
— ANS Z21.45 Assembled Flexible Appliance Connectors of
Other Than All-Metal Construction
The above connectors may be used if acceptable by the authority
having jurisdiction. The state of Massachusetts requires that a exible
appliance connector cannot exceed three feet in length.

National Electrical Code, ANSI/NFPA No. 70.
Should this blower require servicing, the power supply
must be disconnected. For rewiring of any replacement
components, refer to Figures 18 and 19 and the parts list
on pages 30 through 33.
BLOWER ACCESSORY
Operation
The replace insert is equipped with a factory installed blower
accessory that includes a fan control switch, plus a rheostat (speed
control).
The speed control knob is located behind the lower louver at the
right side of the insert.
From a cold start, the temperature activated fan control switch will
normally take 5-10 minutes to heat up and energize the blower.
Start the blower in the "High" setting.
Once the blower is energized, adjust the blower speed control as
desired, then replace the lower louver.
When the insert is shut off, it may take 30-40 minutes for the
heated unit to dissipate (cool down) enough for the blower to shut
off automatically. Note: The blower shut off times will vary on
blower speed and BTU input level setting control by adjustment
of the HI/LO knob located on the gas valve.
Blower removal instructions
Servicing or removal of the blower system must be performed by
a qualied service person.
If the blower assembly must be replaced, the following steps are
recommended for removal:
1. Turn off gas and disconnect the electrical supply.
2. Remove the screen door assembly.
3. Remove the log set.
4. Remove the front surround panel assembly by lifting upward
and outward to detach.
6. Remove the insert from the replace cavity by pulling forward
on the insert.
7. As the insert is moved outward, the gas line may need to be
disconnected at the insert shut off valve. If so, make sure the
main gas line is shut off that supplies gas to the insert.
8. Once the insert is pulled out, the blower assembly can be
removed by locating the (6) screws on the lower back of the
insert that retains the blower base plate.
9. When the screws are removed, gently pull the blower
assembly outward.
10. Disconnect the two ¼” wire terminals from the motor.
