PRODUCT IDENTIFICATION

Figure1 - FULL SIZE VENT-FREE FIREPLACE

WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS

Water vapor is a by-product of gas combustion. An unvented room heater produces approximately one(1) ounce
(30ml) of water for every 1,000 BTU’s(3KW’s)of gas input per hour.
Unvented room heaters are recommended as supplemental heater(a room). Rather than a primary heat source
(an entire house). In most supplemental heat applications, the water vapor does not create a problem. In most
applications,the water vapor enhances the low humidity atmosphere experienced during cold weather.The folling
steps will help insure that water vapor does not become a problem.

1.Be sure the heater is a sized properly for the application, including ample combustion air and circulation air.

2.If high humidity is experienced,dehumidifier may be used to help lower the water vapor content of the air.

3.Do not use an unvented room heater as the primary heat source.

AIR FOR COMBUSTION AND VENTILATION

WARNING: This fireplace

shall not be installed in a confined
space or unusually tight construc­tion 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.

PROVIDING ADEQUATE
VENTILATION

The following are excerpts from
National Fuel Gas Code, NFPA 54/
ANS 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 4 through
5 will help you classify your space
and provide adequate ventilation.

Confined and Unconfined Space

The National Fuel Gas Code, ANS
Z223.1 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.An
unconfining space is defined as a
space whose volume is not 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.

This fireplace shall not be installed
in a confined space or unusually
tight construction unless provisions
are provided for adequate com­bustion and ventilation air.

* Adjoining rooms are communi­cating only if there are door-less
passage ways or ventilation grills
between them.

Unusually Tight Construction

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

Determining if You Have a Confined or Unconfined Space

Use this worksheet to determine if you have a confined or unconfined space.
Space: Includes the room in which you will install heater plus any adjoining rooms with doorless passageways
or ventilation grills between the rooms.

1. Determine the volume of the space (length×width×height).
Length×Width×Height= cu.ft. (volume of space)
Example: Space size 20ft. (length)×16ft. ( width)×8ft. (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. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space can support.

(volume of space)÷50 cu. ft.=(Maximum Btu/Hr the space can support)

Example: 2560 cu. ft. (volume of space)÷50 cu.ft.=51.2 or 51,200(maximum Btu/Hr the space can support)

AIR FOR COMBUSTION AND VENTILATION

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 construction where:

a) walls and ceilings exposed to
the outside atmosphere have a
continuous water vapor retarder with
a rating of one perm ( 6×10

-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 wall­ceiling 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 Inside Building, page

5.
If your home does not meet all of the
three criteria above, proceed to

Determining Fresh-Air Flow For
Heater Location, page 4.

5

WARNING: Rework the worksheet, adding the space of the adjoining unconfined space.

The combined spaces must have enough fresh air to supply all appliances in both spaces.

If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an
unconfined space. You will need no additional fresh air ventilation.

3. Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free heater Btu/Hr
Gas water heater* Btu/Hr
Gas furnace Btu/Hr
Vented gas heater Btu/Hr
Gas heater 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.

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

56,000 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 the worksheet by 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 6.
B. Install a lower Btu/Hr heater, if lower Btu/Hr size makes the room unconfined.

Figure 2 -Ventilation Air From Inside Building

Example:
Gas water heater 30,000 Btu/Hr
Vent-free heater + 26,000 Btu/Hr
Total = 56,000 Btu/Hr

WARNING: If the area in which the fireplace may be operated is smaller than that
defined as an unconfined space or if the building is of unusually tight construction,
provide adequate combustion and ventilation air by one of the methods described in

the National Fuel Gas Code, ANS Z223.1, Section 5.3 or applicable local codes.

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 (see options 1 and 2, Figure 2).
You can also remove door into adjoining room
(see option 3, Figure 2). Follow the National Fuel
Gas Code. NFPA 54/ANS Z223.1. Section 5.3, Air
for Combustion and Ventilation for required size of
ventilation grills or ducts.

Ventilation Air From lnside Building

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. Follow the National Fuel
Gas Code, NFPA 54/ANS Z223.1, Section 5.3. 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 thermostat­controlled power vent. Heated air entering the
attic will activate the power vent.

NOTICE: This fireplace is
intended for use as supplemental

fireplace. Use this fireplace along

with your primary heating system.
Do not install this fireplace as your
primary heat source. If you have a
central heating system, you may
run the system's circulating blower
while using the fireplace. This will
help circulate the heat throughout
the house . In the event of a power
outage, you can use this fireplace
as your primary heat source.

INSTALLATION

WARNING: A qualified service
person must install fireplace. Fol­low all local codes.

WARNING: Never install the

fireplace:

l in a bedroom or bathroom
l in a recreational vehicle
l where curtains, furniture, clothing,

or other flammable objects are
less than 36 inches from the
front, top or sides of the heater

l in high traffic areas
l in windy or drafty areas

WARNING: Maintain the
minimum clearances. If you can,
provide greater clearances from
floor, ceiling, and adjoining side and
back walls.

CAUTION: This fireplace cre­ates warm air currents. These cur­rents move heat to wall surfaces
next to fireplace. Installing fireplace
next to vinyl or cloth wall coverings or
operating fireplace where impurities
(such as tobacco smoke, aromatic
candles,cleaning fluids, oil or
kerosenelamps, etc.) in the air exist,
may discolor walls.

CHECK GAS TYPE

Use only the type of gas indicated on
the plate. If your gas supply can not
meet that requirement, do not install

fireplace. Call dealer where you bought
fireplace for proper type fireplace.

Figure 4 -Minimum Clearance to Wall

CLEARANCES TO COMBUSTIBLES
(Vent-Free Operation Only)

Carefully follow the instructions below.
This fireplace is a freestanding unit
designed to set directly on the floor.

IMPORTANT: You must maintain
minimum wall and ceiling clearances
during installation. The minimum
clearances are shown in Figure 4.
Measure from outermost point of fire­place top.

Minimum Wall and Ceiling
Clearances(see Figure 4)

A. Clearances from outermost point
of fireplace top to any combustible
side wall should not be less than
12 inches.
B. Clearances from the fireplace top
to the ceiling should not be less
than 48 inches.

IMPORTANT: Vent-free fireplace add
moisture to the air. Although this is
beneficial, installing fireplace in rooms
without enough ventilation air may
cause mildew to form from too much
moisture. See Air for Combustion and
Ventilation, pages 4 through 5.

CONNECTING TO GAS SUPPLY

WARNING: A qualified service per­son must connect fireplace to gas
supply. Follow all local codes.

CAUTION: Never connect fireplace
directly to the gas supply. This fireplace
requires an external regulator (not
supplied). lnstall the external regulator
between the fireplace and gas supply.

INSTALLATION ITEMS NEEDED

Before installing fireplace, make sure you
have the items listed below.

l piping (check local codes)
l sealant (resistant to natural or propane/

LP gas)

l equipment shutoff valve*
l test gauge connection**
l sediment trap
l see joint
l pipe wrench
l Flixible gas hose(check local codes)

* A CSA design-certified equipment shutoff
valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Pur­chase the optional CSA design-certified
equipment shutoff valve from your dealer.
See Accessories, page 14.

Figure 7 -Gas Connection

The installer must supply an external
regulator. The external regulator will re­duce incoming gas pressure. You must
reduce incoming gas pressure to be­tween 11 to 14 inches of water. If you do
not reduce incoming gas pressure,fire-

place regulator damage could occur. lnstall

external regulator with the vent pointing
down as shown in Figure 6. Pointing the
vent down protects it from freezing rain
or sleet.

* Purchase the optional CSA design-certified equipment shutoff valve from

your dealer. See Accessories, page 14.

** 11” W.C. pressure is the minimum inlet pressure for purpose of input adjustment.

INSTALLATION

Continued

WARNING: Never connect fireplace
to private (non-utility) gas wells. This gas
is commonly known as wellhead 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 fireplace. If pipe

is too small, undue loss of pressure
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 fireplace (see Figure 7).

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.
Apply pipe joint sealant lightly to threads.
This will prevent excess sealant from
going into pipe. Excess sealant in pipe
could result in clogged fireplace valves.

CAUTION: Use pipe joint sealant
that is resistant to liquid petroleum(LP)
gas.

We recommend that you install a sedi­ment trap in supply line as shown in
Figure 7. 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.

CAUTION: Avoid damage to
regulator. Hold gas regulator with wrench
when connecting into gas piping and/or
fittings.

NG MODELS:
