PRODUCT FEATURES

OPERATION

This appliance is clean burning. It requires
no outside venting. There is no heat loss out
a vent or up a chimney. Heat is generated by
both realistic fl ames and glowing coals. This
appliance is designed for vent-free operation
with fl ue damper closed. It has been tested
and approved to the ANSI Z21.11.2 standard
for unvented appliances. State and local codes
in some areas prohibit the use of vent-free ap­pliances. This appliance may also be operated
as a vented decorative (ANSI Z21.60) product
by opening the fl ue damper.

AIR FOR COMBUSTION AND VENTILATION

WARNING: This heater shall not
be installed in a room or space un­less the required volume of indoor
combustion air is provided by the
method described in the National
Fuel Gas Code, ANSI Z223.1/NFPA
54, the International Fuel Gas Code,
or applicable local codes. Read the
following instructions to ensure
proper fresh air for this and other fuel­burning appliances in your home.

Today’s homes are built more energy effi cient
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, homeowners want
their homes as airtight as possible.

While it is good to make your home energy
effi cient, 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 fi replaces, clothes dryers
and some fuel-burning appliances draw air
from the house to operate. You must provide
adequate fresh air for these appliances. That
will ensure proper venting of vented fuel-burning
appliances.

SAFETY DEVICE

This appliance has a pilot with an Oxygen
Depletion Sensing (ODS) safety shutoff

following ventilation classifi cations:

1. Unusually Tight Construction

2. Unconfi ned Space

3. Confi ned Space
The information on Pages 6 through 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 un­usually tight construction, you must provide
additional fresh air.

Unusually tight construction is defi ned 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
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 fl oors, 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, proceed to Determining Fresh-Air Flow
For Heater Location, Page 7.

Confi ned and Unconfi ned Space

The National Fuel Gas Code, ANSI Z223.1/
NFP A54 allows two methods for determining

whether the space in which the heater is being
installed is confi ned or unconfi ned space. The
standard method defi nes a confi ned space as
a space whose volume is less than 50 cubic

3

feet per 1,000 Btu/hr (4.8 m

per kw) of the ag­gregate input rating of all appliances installed
in that space and an unconfi ned space as
a space whose volume is not less than 50

3

cubic feet per 1,000 Btu/hr (4.8 m

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 un­confi ned space.

Where the air infi ltration rate of a structure is
known, the Known Air Infi ltration 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 confi ned
or unconfi ned.

* Adjoining rooms are communicating only if
there are doorless passageways or ventilation
grills between them.

DETERMINING FRESH-AIR FLOW
FOR HEATER LOCATION

Determining if You Have a Confi ned or
Unconfi ned Space Using the Standard
Method

Use this work sheet to determine if you have
a confi ned or unconfi ned space.

Space: Includes the room in which you will install
fi replace 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 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)
Example: 2560 cu. ft. (volume of space) x 20 =

51,200 (maximum Btu/Hr the space can sup­port)

3. Add the Btu/Hr of all fuel-burning appliances

in the space.

900463-01A 7

SuperiorFireplaces.us.com

Vent-free fi replace __________Btu/Hr
Gas water heater* __________Btu/Hr
Gas furnace __________Btu/Hr
Vented gas heater __________Btu/Hr
Gas fi replace 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 heater __________Btu/Hr
Vent-free fi replace + _________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 used)
Example: 51,200 Btu/Hr (maximum the

space can support)

73,000 Btu/Hr (actual amount of

Btu/Hr used)

The space in the above example is a confi ned
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 worksheet, adding the space of an

adjoining room. If the extra space provides

an unconfi ned space, remove door to adjoin-

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 appliance, if lower Btu/

Hr size makes room unconfi ned.
If the actual Btu/Hr used is less than the maxi-

mum Btu/Hr the space can support, the space is
an unconfi ned space. Y ou 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

INSTALLING DAMPER CLAMP
ACCESSORY FOR VENTED
OPERATION

NOTE: When used as a vented appliance,
appliance must be installed only in a solid­fuel-burning fi replace with a working fl ue and
constructed of noncombustible material.

For Massachusetts Residents Only: Instal­lation of this gas log set as a vented appliance
in the Commonwealth of Massachusetts re­quires the damper be permanently removed
or welded in the fully open position.

If your appliance is a manually-controlled
model, you may use this appliance as a
vented product. There are three reasons for
operating your appliance in the vented mode.

1. The fi replace does not meet the clearance
to combustibles requirements for vent­free operation.

2. State or local codes do not permit vent­free operation.

3. You prefer vented operation.

If reasons number 1 or 2 above apply to you,
you must permanently open chimney fl ue
damper. You must install the damper clamp
accessory (to order, see Accessories, Page

41). This will ensure vented operation (see

Figure 10). The damper clamp will keep

damper open. Installation instructions are
included with clamp accessory.

See chart below for minimum permanent fl ue
opening you must provide. Attach damper
clamp so the minimum permanent fl ue open-
ing will be maintained at all times.

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

• approved fl exible gas line with gas connec-
tor (if allowed by local codes) (not provided)

* An equipment shutoff valve with 1/8" NPT
tap is an acceptable alternative to test gauge
connection. Purchase the optional equipment
shutoff valve from your dealer.

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 exter­nal regulator with the vent pointing down as
shown in Figure 13. Pointing the vent down
protects it from freezing rain or sleet.

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 appliance valves.

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
appliance. 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 appliance

(see Figure 14).
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
requirements for locating equipment shutoff
valve to appliances.
