Why does my fireplace or stove give off odour?
It is normal for your fireplace to give off some odour. This is due to the curing of the paint, adhesives,
silicones and any undetected oil from the manufacturing process as well as the finishing materials used
with the installations (e.g. marble, tile and the adhesives used to adhere this product to the walls can react
with heat and cause odours).
It is recommended that you burn your gas fireplace or stove for a minimum of four hours at a time with
the fan off after the curing of the paint has been completed. These odours can last upward to 40 hours of
burn time, keep burning at a minimum of four hours per use until odours dissipate.
About curing of the paint
Your stove or fireplace has been painted with the highest quality silicone stove paint. This paint dries
quickly in 15-20 minutes when first applied at the factory. However, due to the high temperature silicone
components, the paint will cure when heat is applied to the appliance as it is first used.
The following information applies to the curing process to get the paint fully hard and durable.
Fire the appliance four successive times for 10 minutes each firing and a 5 minute cool down between
each. Be aware during log and firebox paint curing that a white deposit may be developing on the inside
of the glass doors. It is important to remove this white deposit from the glass doors with an appropriate
cleaner to prevent build-up (such as Windex or a commercial fireplace glass cleaner).
• Babies, small children, pregnant women and pets should leave the area during the cure phase.
• Ventilate well, open doors and windows.
• Do not touch during curing.
Noise coming from the fireplace?
• Noise caused by metal expanding and contracting as it heats up and cools down, similar to the sound
produced by a furnace or heating duct. This noise does not affect the operation or longevity of your
fireplace.

AIR FOR COMBUSTION AND VENTILATION
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.
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.
Exhaust fans, fireboxes, clothes dryers, and fuel burning
appliances draw air form the house to operate. You must
provide adequate fresh air for these appliances. This will
insure proper venting of vented fuel-burning appliances.
PROVIDING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code. NFPA 54/ANSI Z223.1, Section 5.3, Air for Combustion and
Ventilation:
All spaces in homes fall into one of the three following ventilation classifications:
1. Unusually Tight Construction 2. Unconfined Space 3. Confined Space.
The information on pages 9 through 11 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
building of usually tight construction, you must provide additional fresh air.
Unusually tight construction is defined 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 10-11 per pasec-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
floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and
at other openings.
If your home meets all of the three criteria above, you must provide additional fresh air.
See Ventilation Air From Outdoors, page 11.
Confined and Unconfined Space
The National Fuel Gas Code (ANSIZ223.1, 1992 Section 5.3) 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.
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.
*Adjoining rooms are communicating only if there are doorless passageways or ventilation grills between them.
DETERMINING AIR FLOW FOR FIREBOX LOCATION
Determining if You Have a Confined or Unconfined Space
Use the work sheet on the next page to determine if you have a confined or unconfined space.
Space: Includes the room in which you will install firebox plus any adjoining rooms with doorless
passageways or ventilation grills between the rooms.
WARNING
This firebox shall not be installed in a confined space
unless provisions are provided for adequate combustion
and ventilation air. Read the following instructions to
insure proper fresh air for this and other fuel-burning
appliances in your home.

9
AIR FOR COMBUSTION AND VENTILATION Cont.
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 22ft. (length) x 18 ft. (width) x 8 ft. (ceiling height) = 3168 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. = 63.3 or 63,300 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free firebox __________________ Btu/Hr
Gas water heater* __________________ Btu/Hr
Gas furnace __________________ Btu/Hr
Vented gas heater __________________ Btu/Hr
Gas firebox logs __________________ Btu/Hr
Other gas appliances* + __________________ Btu/Hr
Total = __________________ Btu/Hr
Example: Gas water heater 40,000 Btu/Hr
Vent-free firebox with log heater + 39,000 Btu/Hr
Total = 79,000Btu/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: 63,300 Btu/Hr (maximum the space can support)
79,000 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 a follows:
A. Rework work sheet, adding the space of an adjoining room. If the extra space provides and unconfined space, remove
door to adjoining room or add ventilation grills between rooms, See Ventilation Air from Inside Building, page 10.
B. Vent room directly to the outdoors. See ventilation Air
from Outdoors, page 11.
C. Install a lower Btu/Hr firebox, if lower Btu/Hr size
makes room unconfined.
If the actual Btu/Hr used is less than the maximum Btu/Hr
the space can support, the space is an unconfined fined
space. You will need no additional fresh air ventilation.
WARNING
If the area in which the firebox and gas log heater may be
operated is smaller than that defined as an unconfined
space, provide adequate combustion and ventilation air by
one of the methods described in the National Fuel Gas
Code, ANSI Z223.1, 1992, Section 5.3.

10
AIR FOR COMBUSTION AND VENTILATION Cont.
VENTILATION AIR FROM INSIDE BUILDING
This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining unconfined space, you
must provide two permanent openings: one within 12” of the ceiling and one within 12” of the floor on the wall connecting
the two spaces. You can also remove door into adjoining
room. Follow the National Fuel Gas Code NFPA
54/ANSIZ223.1, Section 5.3, Air for Combustion and
Ventilation for required size of ventilation for required size
of ventilation grills or ducts.
FIGURE 5 - Ventilation Air from Inside Building
WARNING
Rework worksheet, adding the space of the adjoining
unconfined space. The combined spaces must have
enough fresh air to supply all appliances in both spaces.

11
AIR FOR COMBUSTION AND VENTILATION Cont.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent openings: one within 12” of the
ceiling and one within 12” of the floor. Connect these items directly to the outdoors or spaces open to the outdoors. These
spaces include attics and crawl spaces.
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.
FIGURE 6 - Ventilation Air from Outdoors
Vertical Venting in Cold Climates
In cold climate conditions where temperatures go below -10 degrees Celsius or 14
degrees Fahrenheit, we recommend that the chase be insulated and where the vent
pipe enters into the attic space that the pipe be wrapped with an insulated mylar
sleeve. This will increase the temperature of the vent and help the appliance to
vent properly in cold weather conditions.
It is also important in vertical vented direct vent appliances that the appliance be
operated daily during the winter months as this will help stop the Termination
from freezing up. We recommend using a thermostat set at room temperature to
allow the unit to cycle.

12
INSTALLING – Clearances
IMPORTANT: Vent-free gas log heaters add moisture to
the air. Although this is beneficial, installing firebox in
rooms without enough ventilation air may cause mildew to
form from too much moisture. See Air for Combustion and
Ventilation, pages 8 through 11.
IMPORTANT: Make sure the firebox is level. If firebox is
not level, log set will not work properly.
INSTALLATION CLEARANCES
Carefully follow the instructions below. This will ensure
safe installation.
Minimum Wall and Ceiling Clearances
A. Clearances from the firebox to adjacent wall should
not be less than 6 inches.
B. Clearance from the back of the stove to the
rear wall should not be less than 3 inches.
C. Clearance from the side of unit in corner (45 degree
installation) is 3” inches.
D. Clearance from top of stove is 41 inches.
NOTICE
A qualified service person must install firebox. Follow
all local codes.
WARNING
Never install the firebox
• in a bedroom or bathroom
• in a recreational vehicle
• where curtains, furniture, clothing, or other
flammable objects are less than 36 inches from the
front, top, or sides of the firebox
• in high traffic areas
• in windy or drafty areas
WARNING

INSTALLING
CAUTION
Log heaters installed in this firebox create warm air
currents. These currents move heat to wall surfaces next
to firebox. Installing firebox next to vinyl or cloth wall
coverings or operating firebox where impurities in the
air (such as tobacco smoke) exist, may discolor walls.
WARNING
Never modify or cover the louvered slots on the front
of the firebox.
NOTICE
A qualified service person must install firebox. Follow
all local codes.
NOTICE
Installation and repair should be done by a qualified
service person well trained in the installation of such
appliances. You will also need a building permit from
your local Building Commissioner before installing this
appliance, otherwise your insurance company may not
cover this appliance.
DANGER
CARBON MONOXIDE POISONING
MAY LEAD TO DEATH!
WARNING
Any changes to this heater or its controls can be
dangerous.
CAUTION
Use new black pipe only. Internally tinned copper
tubing can be used in some areas when permitted by
local codes. Only use pipe of 1/2” or greater diameter
to allow full gas volume to heater. Excessive pressure
loss will occur if the pipe is too small.
A manual shutoff valve, union and plugged 1⁄8” NPT
pressure tap pointer must be installed upstream of the
heater.
A sediment trap must be installed upstream of the heater
to prevent moisture and contaminants from passing
through the pipe to the heater controls and burners. Failure
to do so could prevent the heater from operating
reliably.

14
INSTALLING – Gas Line
INSTALLING GAS LINE
Early signs of carbon monoxide poisoning resemble the flu,
with headaches, dizziness, and / or nausea. If you have these
signs, the heater may not be working properly. Get fresh air
at once! Turn off gas appliance. Have appliance serviced.
Some people (such as pregnant women, persons with heart or
lung disease, persons with anemia and those at high altitudes)
are more affected by carbon monoxide than others. Make
certain you read and understand all warnings. Place Burner
Base or Grate Assembly in center of firebox and connect
flexible gas line to incoming black iron pipe gas line.
Do not connect appliance before pressure testing gas piping.
Damage to gas valve may result and an unsafe condition
may be caused.
Prepare incoming black iron gas line with Teflon tape or pipe
joint compound (check with local codes about the use of
Teflon tape). Compounds used on threaded joints of gas piping shall be resistant to the action of Liquefied Petroleum (LP or
Propane) and should be applied lightly to ensure excess sealant does not enter the gas line.
Complete your gas installation by connecting incoming gas line to regulator. Secure all joints tightly with wrench but do not
over-tighten. If a flexible gas line is used, take care not to kink connector. The burner pressure is controlled by the
regulator. Check pressure at the pressure test point, which is located on the side of the gas control near the pilot outlet. Make
sure that the pressure tap is completely closed after checking gas pressure. The pressure should be checked with the
appliance burning and the control set on high.
IMPORTANT: Loosen the pipe adapter on the flex tube
before installing to the system piping.
CHECK GAS TYPE: The gas supply must be the same as
stated on the heater’s rating plate. If the gas supply is
different, Do Not Install the heater. Contact your dealer for the
correct model.
For the state of Massachusetts a T-handle gas shut-off valve must be used on a gas appliance. This T-handle gas shut-
off valve must be listed and approved by the state of Massachusetts. This is in reference to the state of Massachusetts
state code CMR238.
CAUTION
All gas piping and connections must be tested for leaks
after installation is completed. To test, turn gas valve on,
then apply a soap and water solution to all connections
and joints. If bubbles appear, leak can be detected and
corrected. Never use an open flame for leak testing.
Never operate any appliance if a leak is detected!
CAUTION
Any safety screen or guard removed for servicing an
appliance must be replaced prior to operating the heater.

FVF300 Burner System Installation
1. If installed, remove the top grill plates, the top casting, and front casting by simply lifting upwards.
2. Remove front control panel from the base of the stove by loosening the two screws on either side of the control panel and
remove the four hex screws located on the front face of the control panel.
3. Remove the two hex screws from the back edge of the false bottom and then remove the false bottom from the stove. False
bottom may need to be rotated slightly for removal.
4. Place the burner assembly into the stove by slightly rotating it towards yourself. Be careful not to disturb any of the pilot or
valve tubing. Secure the burner to the stove using the four hex screws that are supplied. There is one hole on each side and
two along the back.
5. Use the two hex screws removed in Step 3 and re-install false bottom to its original position.
6. After the burner assembly and false bottom are secure, it is recommended to install the gas line (see gas line instructions in
manual).
7. Once the gas line is connected, the piezo wire can be attached. This is done by locating the single wire lead from the pilot
system and attaching it to the piezo ignitor. For the on/off switch, locate the two wires leading down the back corner of the
unit. Route the two on/off switch wires through the right side panel grommet. Connect one wire to the TP terminal on the valve
and the other to the TPTH terminal (see installation manual for more info). Please note, if fan kit option has been purchased
see fan kit installation instructions at this time to install the fan kit. Once all wiring is connected, line up control panel and
install using the four hex screws that you removed in Step 2. Secure in place.
8. Install the extension knobs by matching the symbol on the knobs to the corresponding one on the valve (on/off goes on on/off
knob on valve).
