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 8 through 10 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 unusually 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 10.
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.

8
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)x8ft.(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 9.
B. Vent room directly to the outdoors. See ventilation Air
from Outdoors, page 10.
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.

9
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 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.

10
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.

This firebox may be installed using a cabinet mantel accessory against a wall in your home. The firebox and cabinet mantel
can be installed directly on the floor.
1. Assemble cabinet mantel. Assembly
instructions are included with each accessory.
2. Install gas piping to firebox location. See
Installing Gas Line, page 17. You may have
to cut an access hole in the floor or wall to
run gas line to firebox. Make sure to locate
access hole so cabinet mantel will cover it
when installed (see Figure 9).
3. Place cabinet mantel on floor in desired
location. Make sure mantel is flush against
wall. Nailing tabs may be removed.
4. Carefully insert firebox into cabinet mantel.
Be careful not to scratch firebox, cabinet
mantel, flooring, etc. when installing.
5. Install and properly test gas log heater. Follow
installation instructions included with the
vent-free gas log heater that is being installed.
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.

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.

CLEANING AND SERVICING OF BURNER/ODS PILOT
It is recommended to annually inspect and clean the unit to prevent malfunction and / or sooting. This operation
should be performed by your dealer or a qualified technician.
Remove log set, handling carefully by holding gently at each end.
(Refer to Log Placement, page 20.) Gloves are recommended to
prevent skin irritation from ceramic.
Annual Cleaning / Inspection
• Do not use cleaning fluids to clean logs or any part of the heater.
• Use a soft bristle brush or a vacuum with brush attachment.
• Vacuum loose particles and dust from burner ports, valve and
blower compartments.
• Vacuum any accumulation of lint from primary mixing tube.
• Inspect ODS pilot for operation, accumulation of lint at the air inlet
holes.
• Verify flame pattern and log placement for proper operation.
• Verify that all ports ignite and cross over smoothly from rear
to front burner.
