UNVENTED PROPANE/LP GAS FIREPLACE

PRODUCT
FEATURES

OPERATION

This vent-free fireplace 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 flames and glow­ing embers. When used without the blower,
the fireplace requires no electricity making
it ideal for emergency backup heat.

SAFETY DEVICE

This fireplace has a pilot with an Oxygen
Depletion Sensing (ODS) safety shutoff sys­tem. The ODS/pilot is a required feature for
vent-free room heaters. The ODS system shuts
off the fireplace if there is not enough fresh air.

PIEZO IGNITION SYSTEM

This fireplace has a piezo ignitor. This sys­tem requires no matches, batteries, or other
sources to light fireplace.

BLOWER ASSEMBLY

(VSGF28PTC)

This fireplace has a blower assembly. The
blower operates thermostatically and has a
variable speed control. The blower circulates
heated air from the fireplace into the room.
Use of blower is optional. Optional blower
accessories are available for model
VSGF28PVA.

THERMOSTAT CONTROL
(VSGF28PTC)

This f ireplace has a thermostat sensing bulb
and a control valve. The thermostat controls
the heat output and flame height. This main­tains a consistent room temperature. Even the
lowest setting provides realistic flames and
glowing embers from two burners. Selecting
higher comfort settings allows fireplace to run
longer, producing greater heat output. At lower
comfort settings, the fireplace will run less.
This results in increased heating comfort. This
can also result in lower gas bills.

VARIABLE MANUAL
CONTROL (VSGF28PVA)

This fireplace has a variable manual control
valve which allows the user to choose the
heat setting that best suits his needs. Any
setting between low and high may be se­lected by simply turning the control knob.

AIR FOR
COMBUSTION AND
VENTILATION

WARNING: This heater 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.

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, fireplaces, clothes dryers, and
fuel burning appliances draw air from the
house to operate. You must provide ad­equate fresh air for these appliances. This
will insure proper venting of vented fuel­burning appliances.

PROVIDING ADEQUATE
VENTILATION

The following are excerpts from National
Fuel Gas Code, ANSI Z223.1/NFPA 54, 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 6 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 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
per pa-sec-m
ings gasketed or sealed

b. weather stripping has been

added on openable windows and
doors

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

From Outdoors

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

Confined Space and Unconfined
Space

The National Fuel Gas Code, ANSI
Z223.1/NFPA 54 defines a confined space

as a space whose volume is less than 50
cubic feet per 1,000 Btu per hour (4.8 m
per kw) of the aggregate input rating of
all appliances installed in that space and
an unconfined space 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 heater 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 doorless passageways or ventila­tion grills between them.

DETERMINING FRESH-AIR FLOW FOR FIREPLACE LOCATION

Determining if You Have a Confined or Unconfined Space

Use this work sheet to determine if you have a confined or unconfined space.
Space: Includes the room in which you will install fireplace 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:

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 = (Maximum Btu/Hr the space can support)

Example:

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

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:

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 adjoin-

ing room or add ventilation grills between rooms. See Ventilation Air from Inside Building, page 6.

B. Vent room directly to the outdoors. See Ventilation Air from Outdoors, page 6.
C. Install a lower Btu/Hr fireplace, 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 space. You will need no
additional fresh air ventilation.

Space size 22 ft. (length) x 18 ft. (width) x 8 ft. (ceiling height) = 3168 cu. ft. (volume of space)

3168 cu. ft. (volume of space) x 20 = 63,360 (maximum Btu/Hr the space can suppor t)

Example:

Gas water heater
Vent-free fireplace +
Total =

63,300 Btu/Hr (maximum the space can support)

INSTALLING GAS PIPING TO
FIREPLACE LOCATION

WARNING: This appliance re­quires a 1/2" NPT (National Pipe
Thread) inlet connection to the
pressure regulator.

Installation Items Needed

Before installing fireplace, 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 (optional)

• tee joint

• pipe wrench
* 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, pages 22 and 23.

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
inches of water. If you do not reduce incom­ing gas pressure, heater regulator damage
could occur. Install external regulator with
the vent pointing down as shown in Figure

17. Pointing the vent down protects it from
freezing rain or sleet.

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
volume will occur.
