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.
• Different types and thicknesses of steel will expand and contract at different rates resulting in
“cracking” and “ticking” sounds throughout the heating and cooling periods.
• You should also be aware that as temperatures change within the unit these sounds will likely re-
occur. Again this is normal for steel fireboxes, and is not a defect.
Cleaning the Glass
During the first few fires, a white film may develop on the glass front, as part of the curing process. The
glass should be cleaned after the unit has cooled down or the film can bake on and become very difficult
to remove. Use a non-abrasive cleaner and do not attempt to clean the glass while it is hot.

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 (ANSI Z223.1, 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/ANSI
Z223.1, 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.

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.

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.

Installation of Burner Systems
INSTALLING BURNER ASSEMBLY INTO FVF350 FIREBOX
1) You will find that the control panel is secured in place with 2 screws. Remove them in order to install
accessories. The control panel is located behind the front door (ashpan door).
2) Before installing the burner assembly, the bottom pan must be removed (bottom pan comes pre-installed)
Remove the 4 hex screws that hold the bottom pan in place. There are 2 along the back and 1 on each
side.
3) Once the bottom pan is removed, place the burner assembly in by slightly rotating it towards yourself.
Being careful not to disturb any of the pilot/valve tubing, rest it in place. Secure the assembly in place by
using the 4 hex screws that were supplied. There is 1 hole on each side and 2 along the back.
4) Once the burner assembly is secure, the bottom pan must be inserted and screwed down. Use the 4 hex
screws to secure. These should be installed the same way they were taken out. 2 in the back and 1 on
each side.
5) After the burner assembly and pan are secure, it’s recommended to install gas line. (See gas line
instructions.) NOTE: For ease of installation, the fan kit option, if purchased, should be installed now. See
page 20.
6) Once the gas line is properly
connected, the control panel
should be re-installed. Find the
white wire leading off the pilot
system and connect it to the piêzo-
igniter. On the on/off switch, you
will see 2 wires leading off the
back. The wires will have
connectors on them which will
connect onto the terminal block. In
no arrangement, connect the wires
to the terminals marked TH and
TPTH. Once all wiring is
connected properly, line up the
control panel with the holes on
either side. Use the 2 hex screws
that you removed previous to
secure in place. NOTE: If you have
a variable speed control switch for
a fan, you should see fan
installation, before securing control
panel.
7) The 2 extension knobs are for the
valve. Place like kind over the other
ON/OFF and HI/LO knobs. NOTE:
These should be put on after the
burner assembly is in place.
