PARTICLES OR OTHER COMBUSTIBLE
MATERIALS THAT COME IN CONTACT WITH
IT WHICH CAN RESULT IN AN EXPLOSION
OR FIRE.

To determine the safest and most efficient
location for your Vent Free Fireplace, you
must take into consideration the following
guidelines:

1. The location must allow for proper clearances for
accessibility of servicing and proper operation (See section
on Fireplace Clearances – page 4).

2. Consider a location where heat output would not be
affected by drafts, air conditioning ducts, windows or doors.

3. Inspect area surrounding the location chosen for the
fireplace for possible air drafts that may affect the flames
and possibly cause sooting. Air drafts may be caused by a
ceiling fan near the fireplace, a hot furnace, or an open
door.

WARNING: DO NOT ALLOW FANS TO
BLOW DIRECTLY INTO THE FIREPLACE.
AVOID ANY DRAFTS THAT ALTER BURNER
FLAME PATTERNS.

4. Due to high temperatures, the appliance should be
located out of traffic and away from furniture and
draperies. Young children should be carefully supervised
when they are in the same room with the appliance.

5. Children and adults should be alerted to the hazards
of high surface temperatures and should stay away to
avoid burns or clothing ignition.

6. Install in an area providing adequate combustion and
ventilation air (see section on adequate combustion and
ventilation air requirements – page 2).

7. Do not install in a building that is of unusually tight
construction. Unusually tight construction is defined as
construction where:

a. Walls and ceilings exposed to the outside

atmosphere have a continuous wall vapor
retarder with a rating of 1 perm or less with
openings gasketed or sealed, and

b. Weather striping 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 penetration for plumbing,
electrical, and gas lines, and at other
openings.

8. Do not install this heater in bedrooms, bathrooms, or
or recreational vehicles.

9. This appliance may be installed in an aftermarket*
manufactured (mobile) home, where not prohibited by
state or local codes.

10. Maintain adequate clearances around air openings.

11. Young children should be carefully supervised when
they are in the same room as the appliance.

12. Keep appliance area clear and free from combustible
materials, gasoline, and other flammable vapors and
liquids.

WARNING: DO NOT ALLOW CLOTHING OR
FLAMMABLE MATERIALS ON OR NEAR THE
FIRPLACE.

PRE-INSTALLATION REQUIREMENTS

WARNING: IF THE AREA IN WHICH THE HEATER MAY BE OPERATED IS SMALLER THAN THAT

DEFINED AS 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, ANSI Z223.1 SECTION 5.3 OR
APPLICABLE LOCAL CODES.

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

The following formula can be used to determine the maximum BTU rating per the definition of unconfined space:
STEP ONE: DETERMINE THE VOLUME OF SPACE IN CUBIC FEET.

LENGTH X WIDTH X HEIGHT = ________________ cu. Ft.
(Include adjoining rooms with doorless passageways or ventilation grills between rooms.)

Example: 24’ (L) X 16’ (W) X 8’ (H) = 3,072. cu. Ft.

STEP TWO: MULTIPLY THE VOLUME OF SPACE BY 20 BTU/Hr. TO DETERMINE THE MAXIMUM BTU/Hr.
THE SPACE CAN SUPPORT.

Example: 3,072 cu. Ft. X 20 BTU/Hr. = 61,440 BTU/Hr.
(Maximum BTU/Hr. the room can support)

STEP THREE: ADD THE BTU/Hr. OF ALL THE FUEL BURNING APPLIANCES IN THE SPACE.
VENT FREE HEATER_________________BTU/Hr.

GAS APPLIANCE #1 _________________BTU/Hr.
GAS APPLIANCE #2 _________________BTU/Hr.
Example: VENT FREE HEATER 26,000 BTU/Hr.

GAS APPLIANCE #1 35,000 BTU/Hr.
TOTAL 61,000 BTU/Hr.

NOTE: DO NOT INCLUDE DIRECT-VENT GAS APPLIANCES. DIRECT VENT IS SEALED
COMBUSTION AND DRAWS COMBUSTION AIR FROM THE OUTDOORS.

THE SPACE IN THE ABOVE EXAMPLE IS AN UNCONFINED SPACE BECAUSE THE 61,000 BTU’S AN HOUR USAGE IS
LESS THATN THE 61,440 BTU’S AN HOUR AVAILABLE. IF THE TOTAL BTU’S AN HOUR USAGE IS GREATER THAN
61,440 BTU’S AN HOUR THEN THE SPACE WOULD BE A CONFINED SPACE AND ADDITIONAL AIR MUST BE

PROVIDED.

The National Fuel Gas Code 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 and 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.

Fireplace Dimensions and Clearances

Refer to the following charts to determine the proper size set for your fireplace.

INSTALLATION SPECIFICATIONS

IMPORTANT: To insure a safe installation into a

masonry or factory built fireplace, the following
instructions must be carefully observed. If installing in a
pre-manufactured fireplace follow the clearance
requirements accompanying that fireplace.

Note: Clearances to Combustible Materials and

Mantle Clearances are in place to provide adequate
spacing to prevent a fireplace mantle or facing from
catching fire. In most cases they should also be
adequate to prevent any discoloration or warping due to
heat. However, each Gas Log installation will present
unique circumstances creating many variables beyond
the control of the Gas Log Manufacturer, including paint
or finish composition, previous heat exposure, quality of
construction, air flow patterns etc. Because of these
variables we cannot guarantee that heat warping or
discoloration will never occur. The possibility of heat
damage exists whether burning wood or gas logs.

Refer to Fig. 1 for the following dimensions:

A. Minimum left and right clearance to combustible walls =

15”.

B. Minimum clearance to combustible ceiling = 42”.
C. Minimum left and right side clearances to mantle = 6”.

Minimum Clearances to Combustible Materials (Vent Free only)

Mantle Clearances (Vent Free only)

DAMPER STOP (Vented Only)

Attach the damper stop clamp to the fireplace damper
blade. Position the clamp to prevent full closure of the
fireplace damper blade.

If the damper stop provided does not fit, the installer shall
install a permanent damper stop that will keep the damper
open to a minimum of 3”.

INSTALLATION SPECIFICATIONS

Woodwork such as mantles and other combustible material
must be installed as tested per Fig. 3 or Fig. 4.

NOTE: Heat Resistant Material as shown in Fig. 3 are

materials such as gypsum board, sheetrock, slate, tile,
marble etc.

If mantle and wall are both non-combustible,
mantle clearances are not applicable.

FIREPLACE HOOD (CANOPY)

A hood (canopy) as shown in Fig. 5 is used to
deflect heat away from the fireplace face and
mantle, reducing the chances of heat damage or
discoloration. If using a hood, it must project a

minimum of 4” from the face of the firebox.

Contact your dealer to purchase a fireplace
hood.

INSTALLER: Please leave these instructions with
the homeowner.
HOMEOWNER: Please retain these instructions for
future reference.

State or local codes may only allow operation of this unit in a
vented application. Check your state and local codes.

All Hargrove vent free room heaters comply with
IAS U.S. Requirement 5-95.

The installation must conform with state and local
codes or, in absence of local codes, to the National
Fuel Gas Code, ANSI Z223.1

IMPORTANT: Before installing in a solid fuel-burning

fireplace, the chimney flue and firebox must be cleaned of
soot, creosote, ashes, and loose paint by a qualified chimney
cleaner.

1. Turn the gas supply to OFF.

2. Turn OFF all electrical power to blower (if applicable)
before installing, servicing, or removing.

3. Clean the fireplace floor, walls, and chimney (if used)
of any ashes, soot creosote, or obstruction. This will
minimize any smell from the fireplace. We recommend
cleaning by a chimney sweep.

4. Any outside air ducts and/or ash dumps in the
fireplace must be permanently closed at the time of
appliance installation.

5. A mesh fireplace screen must be in place when the
appliance is operating unless other provision for

combustion air are provided, the screen shall have an
opening(s) for introduction of combustion air.

IMPORTANT: Read these instructions carefully

before installing or trying to operate this vent free gas
heater.

WARNING: GLASS DOORS MUST BE OPEN

WHEN APPLIANCE IS IN OPERATION.

WARNING: ANY MODIFICATION TO THIS

UNVENTED GAS HEATER OR IT’S CONTROLS

CAN BE DANGEROUS. IMPROPER
INSTALLATION OR USE OF THE HEATER CAN
CAUSE SERIOUS INJURY OR DEATH FROM FIRE,
BURNS, EXPLOSION OR CARBON MONOXIDE
POISONING.
