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 Contruction; 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
per-pa-sec-m2) or less with openings 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

Determining 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 40,000 Btu/Hr
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. V ent 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.
51,200 Btu/Hr (maximum
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.
CAUTION: Never connect
heater directly to the propane
supply. This heater requires an
external regulator (not supplied).
Install the external regulator between the heater and propane
supply.
Installation Items Needed
Before installing heater, make sure you have
the items listed below.
• external regulator (supplied by installer,
see 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.
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
14. Pointing the vent down protects it from
freezing rain or sleet.

Regulator
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 15).
Apply pipe joint sealant lightly to male
threads. This will prevent excess sealant
from going into pipe. Excess sealant in pipe

CAUTION: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.
Install sediment trap in supply line as shown
in Figure 15. 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

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 35).
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 37).
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 38 for location.
If your fireplace has glass doors, position
sensing bulb directly behind door gap on
right bottom side (see Figure 40).

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 41). Slide the thermostat
sensing bulb into the clip.
IMPORTANT:
Do not crimp capillary .

WARRANTY INFORMATION
KEEP THIS WARRANTY
Model

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 PROPANE 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.
