AIR FOR COMBUSTION AND VENTILATION
Today’s homes are built more energy efficient
thanever. Newmaterials,increased insulation
and new construction methods help reduce
heat loss in homes. Homeowners apply
weather strip and caulk around windows and
doors to keepthe cold air out andthe warm air
in. During heating months, homeowners 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 ap-
pliancesneedfreshair 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. That
willensureproperventingofventedfuel-burning
appliances.
PROVIDING ADEQUATE
VENTILATION
Thefollowingareexcerpts from National Fuel
Gas Code, ANSI Z223.1/NFPA 54, 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 Pages6-8 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 un-
usually tight construction, you must provide
additional fresh air.
Unusually tight construction is defined as
construction where:
a. walls and ceilings exposed to the out-
side 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
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 three criteria above,
you must provide additional fresh air. See
Ventilation Air From Outdoors, Page 8.
If your home does not meet all three criteria
above,proceedtoDeterminingFresh-AirFlow
For Heater Location, Page 7.
Confined and Unconfined Space

WARNING: This heater shall not
be installed in a room or space un-
less the required volume of indoor
combustion air is provided by the
method described in the National
Fuel Gas Code, ANSI Z223.1/NFPA

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 sup-
port. 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
anunconfined space,remove doortoadjoin-
ing room or add ventilation grills between
rooms. See Ventilation Air From Inside
Building, Page 8.
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors, Page 8.
C. Install a lower Btu/Hr heater, if lower Btu/Hr
size makes room unconfined.
If the actual Btu/Hr used is less than the maxi-
mum Btu/Hr the space can support, the space is

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: Includesthe roomin whichyou willinstall
fireplace plus any adjoining rooms with door-
less passageways or ventilation grills between
the rooms.
1. Determine the volume of the space (length
x width x height).
LengthxWidth x Height=__________cu. ft.
(volume of space)
Example: Space size 20 ft. (length) x 16 ft.
(width) x 8 ft. (ceiling height) = 2560 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. Multiply the space volume by 20 to determine
the maximum Btu/Hr the space can support.
________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)

MANTEL CLEARANCES
In addition to meeting noncombustible mate-
rial clearances, you must also meet required
clearances between fireplace opening and
mantelshelf.Ifyoudo notmeetthe clearances
listed below, you will need a hood.
Determining Minimum Mantel Clearance
If you meet minimum clearance between
mantel shelf and top of fireplace opening, a
hood is not required (see Figure 6).

Determining Minimum Mantel Clearance
When Using a Hood
If minimum clearances in Figure 6 are not
met, you must have a hood. When using a
hood there are still certain minimum mantel
clearances required. Follow minimum clear-
ances shown in Figure 7, when using hood.
Minimum clearance requirements include any projections such
as shelves, window sills, mantels, etc. above the appliance.
NOTICE: Surface temperatures
ofadjacentwallsandmantelsbe-
comehotduringoperation.Walls
and mantels above the firebox
may become hot to the touch.
If installed properly, these tem-
peratures meet the requirement
ofthenationalproductstandard.
Follow all minimum clearances
shown in this manual.
NOTICE:Ifyourinstallationdoes
not meet the minimum clear-
ances shown, you must do one
of the following:
• operate the logs only with the
flue damper open
• raise the mantel to an accept-
able height
• remove the mantel
FLOOR CLEARANCES
A. If installing appliance on the floor level,
you must maintain the minimum distance
of 14" to combustibles (see Figure 8).
B. If combustible materials are less than
14" to the fireplace, you must install ap-
pliance at least 5" above the top surface
of combustible flooring including tile and
carpet (see Figure 9).

Installation Items Needed
Before installing appliance, make sure you
have the items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approvedflexiblegas line with gasconnec-
tor(ifallowed bylocalcodes)(not provided)
* An equipment shutoff valve with 1/8" NPT
tap is an acceptable alternative to test gauge
connection.
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, appliance
regulator damage could occur. Install exter-
nal regulator with the vent pointing down as
shown in Figure 12. Pointing the vent down
protects it from freezing rain or sleet.

We recommend that you install a sediment
trap in supply line as shown in Figure 13.
Locate sediment trap where it is within reach
for cleaning. Install in piping system between
fuel supply and appliance. Locate sediment
trap where trapped matter is not likely to
freeze. A sediment trap traps moisture and
contaminants. This keeps them from going
intoappliancecontrols.Ifsedimenttrapisnot
installed or is installed wrong, appliance may
not run properly.
