Confined and Unconfined Space

PROVIDING ADEQUATE

VENTILATION

PRODUCT

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 m³per kw) of the aggre-

gate 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 m³per

kw) of the aggregate input rating of all

appliances installed in that space. Rooms

communicating directly with the space in

whichtheappliancesareinstalled*,through

openings not furnished with doors, are con-

sidered a part of the unconfined space.

FEATURES

The following are excerpts from National

Fuel Gas Code, NFPA 54/ANS Z223.1, Sec-

tion5.3, AirforCombustionandVentilation.

OPTIONAL REMOTE

CONTROL ACCESSORIES

All spaces in homes fall into one of the three

following ventilation classifications:

There are four optional remote controls that

canbepurchasedseparatelyforthislogheater:

1. Unusually Tight Construction

2. Unconfined Space

• wall switch

3. Confined Space

• wall thermostat

The information on pages 4 through 6 will

help you classify your space and provide

adequate ventilation.

• hand-held ON/OFF remote

• hand-held thermostat remote

See Accessories, page 24.

This heater shall not be installed in a con-

fined space or unusually tight construction

unless provisions are provided for adequate

combustion and ventilation air.

Unusually Tight Construction

The wall thermostat or hand-held thermo-

stat control may not be used where vented

decorative listing is required.

The air that leaks around doors and win-

dows may provide enough fresh air for

combustion and ventilation. However, in

buildings of unusually tight construction,

you must provide additional fresh air.

* Adjoining rooms are communicating only

iftherearedoorlesspassagewaysorventila-

tion grills between them.

AIR FOR

COMBUSTION AND

VENTILATION

Unusually tight construction is de-

fined as construction where:

a. walls and ceilings exposed to the

outside atmosphere have a con-

tinuous water vapor retarder with

a rating of one perm (6 x 10^-11kg

per pa-sec-m²) or less with open-

ings gasketed or sealed and

or unusually tight construction

unless provisions are provided

foradequatecombustionandven-

tilation air. Read the following in-

structions to insure proper fresh

air for this and other fuel-burning

appliances in your home.

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, be-

tween sole plates and floors, be-

tween wall-ceiling joints, be-

tween wall panels, at penetra-

tions for plumbing, electrical, and

gas lines, and at other openings.

Today’s homes are built more energy effi-

cient than ever. New materials, increased

insulation, and new construction methods

helpreduceheatlossinhomes.Homeowners

weather strip and caulk around windows and

doorstokeepthecoldairoutandthewarmair

in. During heating months, home owners

want their homes as airtight as possible.

If your home meets all of the three

criteria above, you must provide ad-

ditional fresh air. See Ventilation Air

From Outdoors, page 6.

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 com-

bustion and ventilation.

If your home does not meet all of the

threecriteriaabove,proceedtoDeter-

mining Fresh-Air Flow for Heater Lo-

cation, page 5.

Exhaustfans, fireplaces, clothesdryers, and

fuel burning appliances draw air from the

house to operate. You must provide ad-

equate fresh air for these appliances. This

will insure proper venting of vented fuel-

burning appliances.

DETERMINING FRESH-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:Includestheroominwhichyouwillinstallheaterplusanyadjoiningroomswithdoorlesspassagewaysorventilationgrillsbetween

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: 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.

73,000

Btu/Hr

Vented gas heater

Gas fireplace logs

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

73,000 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 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.

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 National Fuel Gas Code, ANS Z223.1, Section 5.3 or applicable local codes.

product. There are three reasons for operat-

ing your heater in the vented mode.

Figure 10 - Attaching Damper Clamp

Note: Install optional FHRC or FHRCT

Receiver and Hand-Held Remote Control

Kit (see Accessories, page 24) before in-

stalling gas log heater. See installation in-

structions included with the kit.

INSTALLING HEATER BASE

ASSEMBLY

1. The fireplace does not meet the clear-

ance to combustibles requirements for

vent-free operation.

CAUTION: Do not remove the

metal data plates attached to the

heater base assembly. The data

platescontainimportantwarranty

information.

1. Apply pipe joint sealant lightly to male

threads of gas fitting. Connect approved

flexible gas hose to inlet side of gas

control (see Figure 11).

2. State or local codes do not permit vent-

free operation.

3. You prefer vented operation.

Ifreasons number 1 or 2 above apply toyou,

you must permanently open chimney flue

damper. You must install the damper clamp

accessory (to order, see Accessories, page

24). This will insure vented operation (see

Figure 10). The damper clamp will keep

damper open. Installation instructions are

included with clamp accessory.

2. Locate two masonry screws in the hard-

ware package.

WARNING: You must secure

this heater to fireplace floor. If

not, heater will move when you

adjust controls. Moving heater

may cause a gas leak.

3. Position heater base assembly in fireplace.

4. Place logs in their proper position on

heater base.

5. Center heater base and logs, front-to-

back and side-to-side in fireplace.

WARNING: If installing in a

sunken fireplace, special care is

needed. You must raise the fire-

place floor to allow access to

heater control panel. This will in-

sure adequate air flow and guard

against sooting. Raise fireplace

floor with noncombustible mate-

rial. Make sure material is secure.

6. Carefully remove logs without moving

heater base.

See chart below for minimum permanent

flue opening you must provide. Attach

damper clamp so the minimum permanent

flue opening will be maintained at all times.

7. Mark screw locations through holes in

front panel of base (see Figure 12, page

11). If installing in a brick-bottom fire-

place, mark screw locations in mortar

joint of bricks.

from going into pipe. Excess sealant in pipe

could result in clogged heater valves.

WARNING: Never connect

CAUTION: Use only new,

black iron or steel pipe. Inter-

nally-tinned copper tubing may

be used in certain areas. Check

yourlocalcodes. Usepipeof1/2"

STOP! Follow “B” in the safety in-

formation above. If you don’t smell

gas, go to the next step.

B. BEFORE LIGHTING smell all

plier, call the fire department.

Note: You may be running this

heater for the first time after hook-

ing up to gas supply. If so, the con-

trol knob may need to be pressed in

for 30 seconds or less. This will allow

air to bleed from the gas system.

Note: Home owners 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 chim-

ney damper (if you have one) fully or

partially to release some of the heat.

7. With control knob pressed in, press

and release ignitor button. This will

light pilot. The pilot is attached to the

front burner. If needed, keep press-

ing ignitor button until pilot lights.

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.

Note: If pilot does not stay lit, con-

tact a qualified service person or gas

supplier for repairs. Until repairs are

made, light pilot with match. To light

pilot with match, see Manual Light-

ing Procedure, page 15.

DESA International warrants this product to be free from defects in materials and components for one (1) year from the date of first

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 International 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 DURA-

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.
