Unusually Tight Construction
AIR FOR COMBUSTION
AND VENTILATION
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.
WARNING: This heater shall
not be installed in a confined
space or unusually tight con-
struction unless provisions are
provided for adequate combus-
tionandventilationair. Readthe
following instructions to insure
proper fresh air for this and
other fuel-burning appliances
in your home.
Unusually tight construction is defined as
construction where:
a. walls and ceilings exposed to the out-
side atmosphere have a continuous
water vapor retarder with a rating of
one perm (6 x 10-11 kg per pa-sec-m2) or
less with openings gasketed or sealed
and
b. weather stripping has been added on
openable windows and doors and
Todayʼs 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.
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.
While it is good to make your home energy effi-
cient, your home needs to breathe. Fresh air must
enter your home.All fuel-burning appliances need
fresh air for proper combustion and ventilation.
If your home meets all of these three cri-
teria, you must provide additional fresh
air. See Ventilation Air From Outdoors,
page 7.
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 fuel-burning appliances.
If your home does not meet all of the
three criteria above, proceed to Determin-
ing Fresh-Air Flow For Heater Location,
page 6.
Confined and Unconfined Space
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.
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 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 com-
municating directly with the space in which the
appliances are installed*, through openings not
furnished with doors, are considered a part of the
unconfined space.
All spaces in homes fall into one of the three fol-
lowing ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 5 through 7 will help
you classify your space and provide adequate
ventilation.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation grills
between them.
117001-01A

The space in the above example is a confined space
because the actual Btu/Hr used is more than the maxi-
mum Btu/Hr the space can support. You must provide
additional fresh air. Your options are as follows:

confined or unconfined space.
C. Install a lower Btu/Hr heater, if lower Btu/Hr size
makes room unconfined.
Space: Includes the room in which you will install
heater plus any adjoining rooms with doorless pas-
sageways or ventilation grills between the rooms.
If the actual Btu/Hr used is less than the maximum
Btu/Hr the space can support, the space is an un-
confined space. You will need no additional fresh
air ventilation.
1. Determine the volume of the space (length x
width x height).
Length x Width x Height =__________cu. ft.
(volume of space)
Example: Space size 20 ft. (6.1 m) (length) x 16
ft. (4.88 m) (width) x 8 ft. (2.44 m) (ceiling height)
= 2560 cu. ft. (72.49 m3) (volume of space)
WARNING: If the area in
which the heater may be oper-
ated is smaller than that defined
as an unconfined space or if the
building is of unusually tight
construction, provide adequate
combustion and ventilation air
byoneofthemethodsdescribed
in the National Fuel Gas Code,
ANSIZ223.1/NFPA54Section5.3
or applicable local codes.
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 = (Maxi-
mum Btu/Hr the space can support)
Example: 2,560 cu. ft. (72.49 m3) (volume of
space) x 20 = 51,200 (maximum Btu/Hr the space
can support)
3. Add the Btu/Hr of all fuel burning appliances in
the space.

Installing Bottom Mounting Screw
1. Locate bottom mounting hole. This hole is
near bottom on back panel of heater (see
Figure 11).
2. Mark screw location on wall.
3. Remove heater from wall.
IMPORTANT: For natural gas, check gas line
pressure before connecting heater to gas line. Gas
line pressure must be no greater than 10.5 inches of
water. If gas line pressure is higher, heater regula-
tor damage could occur.
4. If installing bottom mounting screw into hol-
low or solid wall, install wall anchor. Follow
steps 1 through 5 under Attaching To Wall
Anchor Method, page 9. If installing bottom
mounting screw into wall stud, drill hole at
marked location using 9/64" drill bit.
CAUTION: For propane/LP
gas, never connect heater di-
rectly to the propane/LP supply.
This heater requires an external
regulator (not supplied). Install
theexternalregulatorbetweenthe
heater and propane/LP supply.
5. Replace heater on wall.
6. Insert bottom anchor screw through back
panel into bottom anchor or drilled hole (see
Figure 11).
7. Tighten screw until heater is firmly secured to
wall. Do not over tighten.
Note: Do not replace front panel at this time.
Replace front panel after making gas connec-
tions and checking for leaks (see pages 10
through 12).
For propane/LP gas, 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 pres-
sure, heater regulator damage could occur. Install
the 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. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of
large enough diameter to allow
proper gas volume to heater. If
pipe is too small, undue loss of
volume will occur.

Installation must include equipment 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).
CHECKING GAS CONNECTIONS
WARNING:Testallgaspiping
and connections, internal and
external to unit, for leaks after
installing or servicing. Correct
all leaks at once.
IMPORTANT: Install an equipment shutoff valve
in an accessible location. The equipment shutoff
valve is for turning on or shutting off the gas to
the appliance.
Apply pipe joint sealant lightly to male NPT
threads. This will prevent excess sealant from
going into pipe. Excess sealant in pipe could result
in clogged heater valves.
WARNING: Never use an
open flame to check for a leak.
Applyanoncorrosiveleakdetec-
tion fluid to all joints. Bubbles
forming show a leak. Correct all
leaks at once.
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.
Install sediment trap in supply line as shown in
Figure 13. 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: For propane/LP
gas, make sure external regula-
tor has been installed between
propane/LP supply and heater.

THERMOSTAT CONTROL
OPERATION
Blue Flame
Pilot Burner
The thermostatic control used on these models
differs from standard thermostats. Standard
thermostats simply turn on and off the burner.
The thermostat used on this heater senses the
room temperature. At times the room may
exceed the set temperature. If so, the burner
will shut off. The burner will cycle back on
when room temperature drops below the set
temperature. The control knob can be set to
any heat level between 1 and 5. This adjusts the
amount of gas flow to the burner that increases
or decreases the burner flame height.
Thermocouple

Thermocouple
Note: The thermostat sensing bulb measures
the temperature of air near the heater cabinet.
This may not always agree with room tem-
perature (depending on housing construction,
installation location, room size, open air tem-
peratures, etc.) Frequent use of your heater will
let you determine your own comfort levels.

MANUAL LIGHTING
PROCEDURE
1. Remove front panel (see Figure 10, page 9).
2. Follow steps 1 through 7 under Lighting
Instructions, page 13.
WARNING: If yellow tipping
occurs, your heater could pro-
duce increased levels of car-
bon monoxide. If burner flame
pattern shows yellow tipping,
proceed with the following in-
structions.
3. With control knob pressed in, strike match.
Hold match to pilot until pilot lights.
4. Keep control knob pressed in for30 seconds
after lighting pilot.After 30 seconds, release
control knob. Now follow step 9, under
Lighting Instructions, page 13.
5. Replace front panel.
NOTICE: Do not mistake orange
flames with yellow tipping. Dust
or other fine particles enter the
heater and burn causing brief
patches of orange flame.
INSPECTING HEATER
Check pilot flame pattern and burner flame pat-
tern often.
PILOT FLAME PATTERN
Figure 20 shows a correct pilot flame pattern.
Figure 21 shows an incorrect pilot flame pattern.
The incorrect pilot flame is not touching the
thermocouple. This will cause the thermocouple
to cool. When the thermocouple cools, the heater
will shut down.
If burner flame pattern is incorrect, as shown in
Figure 23, page 15,

BURNER PILOT AIR INLET
INSPECTING HEATER
The primary air inlet holes allow the proper
amount of air to mix with the gas. This provides a
clean burning flame. Keep these holes clear of dust,
dirt and lint. Clean these air inlet holes prior to each
heating season. Blocked air holes will create soot.
We recommend that you clean the unit every three
months during operation and have heater inspected
yearly by a qualified service person.
Continued
1/2 GLASS HEIGHT
(Models GWN6 and GWP6 will be lower due to
lower input rating)
We also recommend that you keep the burner
tube and pilot assembly clean and free of dust and
dirt. To clean these parts we recommend using
compressed air no greater than 30 PSI. Your local
computer store, hardware store or home center
may carry compressed air in a can. You can use a
vacuum cleaner in the blow position. If using com-
pressed air in a can, please follow the directions on
the can. If you don't follow directions on the can,
you could damage the pilot assembly.

1. Shut off the unit, including the pilot. Allow
the unit to cool for at least thirty minutes.
2. Inspect burner, pilot for dust and dirt.
CLEANING AND
MAINTENANCE
3. Blow air through the ports/slots and holes in
the burner.
4. Never insert objects into the pilot tube.
WARNING: Turn off heater
and let cool before cleaning.
Clean the pilot assembly also. A yellow tip on the
pilot flame indicates dust and dirt in the pilot as-
sembly. There is a small pilot air inlet about two
inches from where the pilot flame comes out of
the pilot assembly (see Figure 24). With the unit
off, lightly blow air through the air inlet. You may
blow through a drinking straw if compressed air
is not available.
CAUTION: You must keep
control areas, burner and circu-
latingairpassagewaysofheater
clean. Inspect these areas of
heater before each use. Have
heater inspected yearly by a
qualifiedserviceperson. Heater
may need more frequent clean-
ing due to excessive lint from
carpeting, beddingmaterial, pet
hair, etc.

LIMITED WARRANTIES FOR NEW AND FACTORY
RECONDITIONED PRODUCTS
New Products: DESAHeating Products warrants this heater and any parts thereof, to be free of defects in materials
and workmanship for two (2) years from the date of first purchase, when operated and maintained in accordance
with the manufacturer's instructions. These warranties are extended only to the original retail purchaser, when
proof of purchase is provided.
Factory Reconditioned Heaters: DESAHeating Products warrants this factory reconditioned heater and any parts
thereof, to be free of defects in materials and workmanship for thirty (30) days from the date of first purchase,
when operated and maintained in accordance with the manufacturer's instructions. These warranties are extended
only to the original retail purchaser, when proof of purchase is provided.
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 Heating Products 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, INCLUD-
ING WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE TO TWO
(2) YEARS FROM THE DATE OF FIRST PURCHASE; AND DESA HEATING PRODUCTSʼ LIABILITY IS
HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND DESA HEATING PRODUCTS
SHALL NOT BE LIABLE FOR ANY OTHER DAMAGES WHATSOEVER INCLUDING INDIRECT, INCI-
DENTAL 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.
