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. Homeowners apply 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, some fireplaces, clothes dryers and
some fuel-burning appliances draw air from the
house to operate. You must provide adequate fresh
air for these appliances. This will ensure proper
venting of vented fuel-burning appliances.
PROVIDING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas
Code ANS Z223.1/NFPA 54,Air for Combustion
and Ventilation.
All spaces in homes fall into one of the three fol-
lowing ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on Pages 7 Through 9 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.
Unusually tight construction is defined as con-
struction 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 kg
per pa-sec-m2) or less with openings gasketed
or sealed and
b. weather stripping has been added on open-
able 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 Ventila-
tion Air From Outdoors, Page 9.
If your home does not meet all of the three criteria
above, proceed to Determining Fresh-Air Flow for
Firebox Location, Page 8.
Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1/ NFPA54
allows two methods for determining whether the
space in which the heater is being installed is con-
fined or unconfined space. The standard method
defines a confined space as a space whose volume
is less than 50 cubic feet per 1,000 Btu/hr (4.8 m3
per kw) of the aggregate input rating of all appli-
ances installed in that space and an unconfined
space as a space whose volume is not less than
50 cubic feet per 1,000 Btu/hr (4.8 m3per 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.
This appliance shall not be installed in a confined
space or unusually tight construction unless provi-
sions are provided for adequate combustion and
ventilation air.
Where the air infiltration rate of a structure is
known, the Known Air Infiltration Rate Method may
be used. Follow The National Fuel Gas Code, ANSI
Z223.1/NFPA 54 to use this method to determine
if the space is confined or unconfined.
* Adjoining rooms are communicating only if there
are doorless passageways or ventilation grills
between them.

DETERMINING FRESH-AIR FLOW FOR
FIREBOX LOCATION
Determining if You Have a Confined or Unconfined
Space Using the Standard Method
Use this work sheet to determine if you have a
confined or unconfined space.
Space: Includes the room in which you will install
appliance plus any adjoining 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 22 ft. (length) x 18 ft. (width)
x 8 ft. (ceiling height) = 3168 cu. ft. (volume of
space)
If additional ventilation to adjoining room is sup-
plied with grills or openings, add the volume of
these rooms to the total volume of the space.
2. Multiply the space volume by 20 to determine the
maximum Btu/Hr the space can support.
__________ (volume of space) x 20 = (Maximum
Btu/Hr the space can support)
Example:3168 cu. ft. (volume of space) x 20 =
63,360 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in
the space.
Gas water appliance* ____________ Btu/Hr
Gas furnace ____________ Btu/Hr
Vented gas appliance ____________ Btu/Hr
Gas fireplace logs ____________ Btu/Hr
Other gas appliances* + ___________ Btu/Hr
Total = ___________ Btu/Hr
* Do not include direct-vent gas appliances. Direct-
vent draws combustion air from the outdoors and
vents to the outdoors.
Example:
Gas water appliance ____________ Btu/Hr
Gas firebox logs + ___________ Btu/Hr
Total = ___________ Btu/Hr
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:35,840 Btu/Hr (maximum the space
can support)
40,000 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
as follows:
A. Rework work sheet, 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
9.
B. Vent room directly to the outdoors. See Ventila-
tion Air from Outdoors, Page 9.
C. Install a lower Btu/Hr gas log appliance, 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 un-
confined space. You will need no additional fresh
air ventilation.
WARNING: If the area in which
the appliance may be operated does
not meet the required volume for
indoor combustion air, combustion
and ventilation air shall be provided
by one of the methods described in
the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, the International
Fuel Gas Code, or applicable local
codes.

SuperiorFireplaces.us.com
126872-01C 9
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining un-
confined 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 (see options 1 and 2, Figure 4). You can
also remove door into adjoining room (see option 3,
Figure 4). Follow the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, Air for Combustion and Ventila-
tion for required size of ventilation grills or ducts.
AIR FOR COMBUSTION AND VENTILATION
Continued
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills
or ducts. You must provide two permanent open-
ings: 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. Follow the
National Fuel Gas Code, ANSI Z223.1/NFPA 54, 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.

WARNING: Use pipe joint sealant
that is resistant to liquid petroleum
(LP) gas.
CAUTION: Use only new, black
iron or steel pipe. Internally-tinned
copper tubing may be used in certain
areas. Check your local codes. Use
pipe of 1/2" diameter or greater to
allow proper gas volume to heater.
If pipe is too small, undue loss of
volume will occur.
Installation must include an 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
22, Page 19).
IMPORTANT: Install equipment shutoff valve in
an accessible location. The equipment shutoff
valve is for turning on or shutting off the gas to
the appliance.
Check your building codes for any special require-
ments for locating equipment shutoff valve to
fireplaces.
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
fireplace valves.
CONNECTING TO GAS SUPPLY
WARNING:Thisappliancerequiresa
45°maleflarefitting5/8"-18UNF(Unified
National Fine Thread) inlet connection
and the flexible gas line provided.
WARNING: A qualified service
person must connect appliance to gas
supply. Follow all local codes.
IMPORTANT:For natural gas, check gas line pres-
sure before connecting fireplace to gas line. Gas line
pressure must be no greater than 14" of water. If
gas line pressure is higher, heater regulator dam-
age could occur.
CAUTION:Neverconnectpropane/
LP fireplace directly to the propane/
LP supply. This heater requires an
external regulator (not supplied).
Install the external regulator between
the heater and propane/LP supply.
For propane/LP units, the installer must supply an
external regulator. The external regulator will reduce
incoming gas pressure. You must reduce incoming
gas pressure to between 11" and 14" of water. If
you do not reduce incoming gas pressure, fireplace
regulator damage could occur. Install external
regulator with the vent pointing down as shown in
Figure 21. Pointing the vent down protects it from
freezing rain or sleet.
WARNING: Never connect this appli-
ance to private (non-utility) gas wells. This
gas is commonly known as wellhead gas
and does not have odorants and may have
impurities, and variations in BTU content.
The use of well-head gas will void the
manufacturer’s warranty to this appliance.

We recommend that you install a sediment trap in
supply line as shown in Figure 22. Locate sediment
trap where it is within reach for 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
fireplace controls. If sediment trap is not installed
or is installed wrong, fireplace may not run properly.
