FEATURES

Operation

This heater 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 coals.
This heater is designed for vent-free opera­tion with flue damper closed. State and local
codes in some areas prohibit the use of vent­free heaters. You can operate heater as a
vented product by opening flue damper.

Safety Device

This heater has a pilot with an Oxygen
Depletion Sensor Shutoff System (ODS).
The ODS/pilot is a required feature for vent­free room heaters. The ODS/pilot shuts off
the heater if there is not enough fresh air.

Piezo Ignition System

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

UNVENTED NATURAL GAS LOG HEATER

AIR FOR
COMBUSTION AND
VENTILATION

WARNING: This heater shall
not be installed in a confined
space 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 is exerpts from National Fuel
Gas Code. NFPA 54/ANSI 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 and 5 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
less with openings gasketed or
sealed

b.weather stripping has been

added on openable windows
and doors

c.caulking or sealants are ap-

plied 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

Deter-

mining Air Flow For Heater Location

Confined and Unconfined Space

The National Fuel Gas Code (ANSIZ2123.1,
1992 Section 5.3) 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 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.

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

DETERMINING AIR FLOW
FOR HEATER 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 heater 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:

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. 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:

space) ÷ 50 cu. ft. = 51.2 or 51,200

.

(maximum Btu/Hr the space can sup­port)

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 fireplace logs ________ Btu/Hr
Other gas appliances* + ___ Btu/Hr
Total = __ Btu/Hr

Example:

Gas water heater

Vent-free heater + 33,000 Btu/Hr
Total = 73,000 Btu/Hr
* Do not include direct-vent gas appli-

ances. 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 worksheet, 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 Ventila-
tion Air From Inside Building.

B. Vent room directly to the outdoors. See

Ventilation Air From Outdoors.

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

the space can support)

73,000 Btu/Hr (actual
amount of Btu/Hr used)

VENTILATION AIR

Ventilation Air From Inside Building

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

WARNING: Rework worksheet, adding the space of the adjoining
unconfined space. The combined spaces must have enough fresh air to
supply all appliances in both spaces.

CONNECTING TO GAS
SUPPLY

NOTICE: A qualified service per­son must connect heater to gas
supply. Follow all local codes.

Installation Items Needed

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

• piping (check local codes)

• sealant (resistant to LP gas)

• manual shutoff valve *

• test gauge connection *

• sediment trap

• tee joint

• pipe wrench

* An A.G.A. design-certified manual shutoff
valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Pur­chase the optional A.G.A. design-certified
manual shutoff valve from your dealer. See
Accessories, page 23.

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

Install sediment trap in supply line as shown
in Figure 14. Locate sediment trap where it
is within reach for cleaning. Locate sedi­ment trap where trapped matter is not likely
to freeze. A sediment trap traps moisture
and contaminants. This keeps them from
going into heater controls. If sediment trap
is not installed or is installed wrong, heater
may not run properly.

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

WARNING: Never connect
heater 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 heater. If
pipe is too small, undue loss of
pressure will occur.

Installation must include a manual 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
heater (see Figure 14).

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

POSITIONING OF
THERMOSTAT
SENSING BULB

For Masonry and Factory­built Metal Fireplace

If your log set cycles to pilot, but
the room temperature drops to a
lower than ideal comfort level
before the log set comes back on,
you may want to reposition the
thermostat sensing bulb.

The thermostat sensing bulb is located on
the gas valve assembly. This location
allows the thermostat to keep the room
temperature at an ideal comfort level for
most fireplace applications. For position­ing the thermostat sensing bulb elsewhere,
an adhesive-backed mounting clip has
been provided.

Tools needed: 5/16" hex driver or socket

1. Locate the gas valve assembly and ther­mostat sensing bulb (see Figure 34).

Gas Valve
Assembly

Thermostat
Sensing Bulb

Figure 34 - Location of Gas Valve
Assembly and Thermostat Sensing Bulb

2. The adhesive-backed mounting clip
(see Figure 35) is attached to the ther­mostat sensing bulb. Remove the ad­hesive-backed mounting clip.

3. With 5/16" hex driver or socket, loosen
the thermostat screw. Carefully slide
the thermostat sensing bulb out of the
retaining clamp (see Figure 36).

Note:

Do not remove the screw . Make
sure you tighten the screw after remov­ing the thermostat sensing bulb.

IMPORTANT:

Do not force or bend

the thermostat sensing bulb or capillary .

4. The thermostat sensing bulb may be
located to the lower right front side of
fireplace. Determine location of sens­ing bulb, but do not mount sensing bulb
until step 5. If you have a masonry fire­place, see Figure 37 for location.

5. The mounting clip must be a minimum
of 3" from bottom of fireplace to pre­vent crimping of capillary. Once you
have decided on a location, clean the
area thoroughly. Remove the paper
backing from the adhesive on back of
mounting clip. Press the clip into the
new location so that the thermostat
sensing bulb will be positioned verti­cally with the capillary at the bottom
(see Figure 40). Slide the thermostat
sensing bulb into the clip.

Date Purchased

Always specify model and serial numbers when communicating with the factory.

We reserve the right to amend these specifications at any time without notice. The only warranty applicable is our
standard written warranty. We make no other warranty, expressed or implied.

LIMITED WARRANTY

VENT-FREE NATURAL GAS LOG HEATERS

DESA International warrants this product to be free from defects in materials and components for three (3) years and five
(5) years on stainless steel burners from the date of first purchase, provided that the product has been properly installed,
operated and maintained in accordance with all applicable instructions. To make a claim under this warranty the Bill of
Sale or cancelled check must be presented.

This warranty is extended only to the original retail purchaser. This warranty covers the cost of part(s) required to restore
this heater to proper operating condition and an allowance for labor when provided by a DESA Authorized Service Center.
Warranty part(s) MUST be obtained through authorized dealers of this product and/or DESA International who will
provide original factory replacement parts. Failure to use original factory replacement parts voids this warranty. The heater
MUST be installed by a qualified installer in accordance with all local codes and instructions furnished with the unit.

This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts that fail
or become damaged as a result of misuse, accidents, lack of proper maintenance or defects caused by improper installation.
Travel, diagnostic cost, labor, transportation and any and all such other costs related to repairing a defective heater will
be the responsibility of the owner.

TO THE FULL EXTENT ALLOWED BY THE LAW OF THE JURISDICTION THAT GOVERNS THE SALE OF THE
PRODUCT; THIS EXPRESS WARRANTY EXCLUDES ANY AND ALL OTHER EXPRESSED WARRANTIES
AND LIMITS THE DURATION OF ANY AND ALL IMPLIED WARRANTIES, INCLUDING WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE TO THREE (3) YEARS ON ALL COMPO­NENTS AND FIVE (5) YEARS ON STAINLESS STEEL BURNERS FROM THE DATE OF FIRST PURCHASE; AND
DESA INTERNATIONAL’S LIABILITY IS HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT
AND DESA INTERNATIONAL SHALL NOT BE LIABLE FOR ANY OTHER DAMAGES WHATSOEVER
INCLUDING INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES.

Some states do not allow a limitation on how long an implied warranty lasts or an exclusion or limitation of incidental or
consequential damages, so the above limitation on implied warranties, or exclusion or limitation on damages may not apply
to you.

This warranty gives you specific legal rights, and you may also have other rights that vary from state to state.
