AIR FOR

COMBUSTION

AND

WARNING

WARNING ICON

001

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.

VENTILATION

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 fuel-burning 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 5 through 7 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 continu-

ous water vapor retarder with a rating of one perm or less with open-

ings gasketed or sealed and

b. weather stripping has been added on openable windows and doors and

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 addi-

tional fresh air. See Ventilation Air From Outdoors, page 7.

If your home does not meet all of the three criteria above, proceed to page 6.

Unconfined Space

The National Fuel Gas Code, ANSIZ223.1, 1992, Section 5.3 defines uncon-

fined space as having a minimum air volume of 50 cubic feet (127 cubic cm) for

each 1000 Btu/Hr input rating of all appliances in the space (cubic feet equals

length x width x height of space). Include adjoining rooms only if there are

doorless passageways or ventilation grills between the rooms.

Confined Space

The National Fuel Gas Code, ANSIZ223.1, 1992, Section 5.3 defines confined

space as having an air volume of less than 50 cubic feet (127 cubic cm) for each

1000 Btu/Hr input rating of all appliances in the space (cubic feet equals length

x width x height of space). Include adjoining rooms only if there are doorless

passageways or ventilation grills between the rooms.

DETERMINING AIR FLOW FOR HEATER LOCATION

AIR FOR

COMBUSTION

AND

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.

VENTILATION

1. Determine the volume of the space (length x width x height).

Continued

Length x Width x Height =

___________________

cu. ft. (volume of space)

Example: Space size 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: 2560 cu. ft. (volume of 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

Gas water heater*

Vented gas heater

Gas fireplace logs

Other gas appliances*

Total

___________________ Btu/Hr

= ___________________ Btu/Hr

Example: Gas water heater

Vent-free heater

Total

40,000

39,000

79,000

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: 51,200 Btu/Hr (maximum the space can support)

79,000 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 Ventilation Air From Inside Building, page 7.

B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 7.

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.

AND

WARNING

If the area in which the heater may be operated is smaller than

that defined as an unconfined space, provide adequate combus-

tion and ventilation air by one of the methods described in the

National Fuel Gas Code, ANSI Z223.1, 1992, Section 5.3.

VENTILATION

Continued

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 2). You can also remove door into adjoining room (see option 3, Figure 2).

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.

Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream

from heater (see Figure 14, page 17).

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, page 17. Locate sedi-

ment 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.

C. Use only your hand to push in or turn the gas control knob. Never use tools. If the

knob will not push in or turn by hand, don’t try to repair it, call a qualified service

technician or gas supplier. Force or attempted repair may result in a fire or

explosion.

D. Do not use this appliance if any part has been under water. Immediately call a

qualified service technician to inspect the appliance and to replace any part of the

control system and any gas control which has been under water.

LIGHTING INSTRUCTIONS

WARNING

• If fireplace has glass doors, never operate this heater with glass doors

closed. If you operate heater with doors closed, heat buildup inside

fireplace will cause glass to burst. Also if fireplace opening has vents at

the bottom, you must open the vents before operating heater.

• You must operate this heater with a fireplace screen in place. Make sure

fireplace screen is closed before running heater.

NOTICE

During initial operation of new heater, burning logs will give off a paper-

burning smell. Orange flame will also be present. Open damper or

window to vent smell. This will only last a few hours.

Note: Homeowners generally prefer to operate their heater with the chimney damper

closed. This will put all the heat into the room. However there may be times you will

desire the full flames of the Hi heat setting but will find the heat output excessive. You

can open the chimney damper (if you have one) fully or partially to release some of

the heat. WARNING: Damper handle will be hot if heater has been running.

THERMOSTAT CONTROL OPERATION

(Thermostat-Controlled Models Only)

The thermostat control knob can be set to any comfort level between Hi and Lo. The

thermostat will gradually modulate the heat output and flame height from higher to

lower settings, or pilot, in order to maintain the comfort level you select. The ideal

comfort setting will vary by household depending upon the amount of space to be

heated, the output of the central heating system, etc.

Note: Selecting the Hi setting with the control knob will cause the burner to remain

fully on, without modulating down in most cases.

MANUAL LIGHTING PROCEDURE

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

COMFORT GLOW VENT-FREE PROPANE GAS LOG HEATERS

DESA International warrants this product to be free from defects in materials and components for one (1) year 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 MER-

CHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE TO ONE (1) YEAR ON ALL COMPONENTS

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.
