AIR FOR
COMBUSTION AND
VENTILATION

WARNING: This heater shall
not be installed in a confined space
or unusually tight construction
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 are excerpts from National
Fuel Gas Code. NFPA 54/ANS 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 through 6 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

De-

Confined and Unconfined Space

The National Fuel Gas Code ANS Z223.1

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.

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

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

DETERMINING FRESH-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:

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:

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
* Do not include direct-vent gas appliances. 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 adjoin-

ing room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 6.

B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 6.
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.

Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) =2560 cu. ft. (volume of space)

2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (maximum Btu/Hr the space can support)

Example:

Gas water heater 40,000 Btu/Hr
Vent-free heater + 20,000 Btu/Hr
Total = 60,000 Btu/Hr

51,200 Btu/Hr (maximum the space can support)
60,000 Btu/Hr (actual amount of Btu/Hr used)

WARNING: If the area in which the heater may be operated is smaller than that defined as an 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

104332

CONNECTING TO GAS
SUPPLY

WARNING: This appliance re­quires a 3/8" NPT (National Pipe
Thread) inlet connection to the
pressure regulator.

WARNING: 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.

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 large
enough diameter 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 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 14).

IMPORTANT:

Install an equipment shutoff

valve in an accessible location. The equip-

ment shutoff valve is for turning on or
shutting off the gas to the appliance.

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 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.

IMPORTANT:

Hold pressure regulator with
wrench when connecting it to gas piping
and/or fittings.

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

13. Pointing the vent down protects it from
freezing rain or sleet.

THERMOSTAT

CONTROL

OPERATION

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. The thermostat adjusts the
amount of gas flow to the burner. This
increases or decreases the burner flame
height. 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 HI and LO.

Note:

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

MANUAL LIGHTING

PROCEDURE

1. Remove front panel (see Figure 7,

page 8).

2. Follow steps 1 through 5 under Light-

ing Instructions.

3. With control knob pressed in, strike

INSPECTING
BURNER

Check pilot flame pattern and burner flame
pattern often.

PILOT FLAME PATTERN

Figure 19 shows a correct pilot flame pattern.
Figure 20 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 pilot flame pattern is incorrect, as shown
in Figure 20

• turn heater off (see To Turn Off Gas to
Appliance, page 12)

• see Troubleshooting, pages 14 through 16

CLEANING AND
MAINTENANCE

WARNING: Turn off heater

and let cool before cleaning.

CLEANING BURNER
PILOT AIR INLET HOLE

We recommend that you clean the unit ev­ery 2,500 hours of operation or every three
months.

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 compressed 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.

3. Blow air through the ports/slots and
holes in the burner.

Clean the pilot assembly also. A yellow tip on
the pilot flame indicates dust and dirt in the pilot
assembly. There is a small pilot air inlet hole
about two inches from where the pilot flame
comes out of the pilot assembly (see Figure 23).
With the unit off, lightly blow air through the air
inlet hole. You may blow through a drinking
straw if compressed air is not available.

Pilot Air Inlet
Hole

Figure 20 - Incorrect Pilot Flame Pattern

BURNER FLAME PATTERN

Figure 21 shows a correct burner flame
pattern. Figure 22 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
glass panel height.

WARNING: If yellow tipping
occurs, your heater could pro­duce increased levels of carbon
monoxide. If burner flame pattern
shows yellow tipping, follow in­structions at bottom of this page.

104332

CAUTION: You must keep
control areas, burner, and circu­lating air passageways of heater
clean. Inspect these areas of
heater before each use. Have
heater inspected yearly by a quali­fied service person. Heater may
need more frequent cleaning due
to excessive lint from carpeting,
bedding material, pet hair, etc.

ODS/PILOT AND BURNER

LIMITED WARRANTY

COMFORT GLOW VENT-FREE PROPANE/LP GAS HEATERS

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 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 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.
