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 excerpts 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 3 through 5 will
help you classify your space and provide
adequate ventilation.
3
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 (6x10
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 page 4.

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
unconfining 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 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 x width x height).
Length x Width x Height =
___________cu. ft. (volume of space)
Example:
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
Space size 20 ft. (length) x
2560 cu. ft. (volume of
Example:
Gas water heater 40,000 Btu/Hr
Vent-free heater + 20,000 Btu/Hr
Total = 60,000 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 can support)
60,000 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 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 V entila-
tion Air From Inside Building.
B. Vent room directly to the outdoors. See
V entilation Air From Outdoors, page 5.
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.
WARNING: If the area in
which the heater may be operated is smaller than that defined
as an unconfined space, provide
adequate combustion and ventilation air by one of the methods
described in the
Gas Code, ANSI Z223.1, 1992,
Section 5.3
codes.

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/LP
supply. This heater requires an
external regulator (not supplied).
Install the external regulator between the heater and propane/LP
supply.
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
12. 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 heater. If
pipe is too small, undue loss of
pressure will occur.
Typical Inlet Pipe Diameters
20,000 Btu/Hr models 3/8" or greater
30,000 Btu/Hr models 1/2" or greater
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 13, page 9).
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.
CAUTION: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.
Install sediment trap in supply line as shown
in Figure 13, page 9. 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.

• turn heater off (see To Turn Off Gas to
Appliance,)
•
see Troubleshooting, pages 12 through 14
BURNER FLAME PATTERN
Figure 20 shows a correct burner flame
pattern. Figure 21 shows an incorrect burner
flame pattern. The incorrect burner flame
pattern shows yellow tipping of the flame. It
also shows the flame higher than 1/2 the

occurs, your heater could produce increased levels of carbon
monoxide. If burner flame pattern shows yellow tipping, follow
instructions at bottom of this
page.
NOTICE: Do not mistake orange
flames with yellow tipping. Dirt
or other fine particles enter the
heater and burn causing brief
patches of orange flame.

DESA International warrants this product to be free from defects in materials and components for two (2) years 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 only the cost of part(s) required to restore
this heater to proper operating condition. 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 TWO (2) YEARS 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.
