carbon monoxide poisoning resemble the u,

with headaches, dizziness or nausea. If you

have these signs, the replace may not be

working properly. Get fresh air at once! Have

replace serviced. Some people are more af-

fected by carbon monoxide than others. These

include pregnant women, people with heart or

lung disease or anemia, those under the inu-

odor added to the gas can fade. Gas may be

present even though no odor exists.

Make certain you read and understand all

warnings. Keep this manual for reference. It

is your guide to safe and proper operation of

this replace.

Today’s homes are built more energy efcient

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

efcient, your home needs to breathe. Fresh

air must enter your home. All fuel-burning ap-

pliances need fresh air for proper combustion

and ventilation.

Exhaust fans, replaces, 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 appli-

ances.

The following are excerpts from National Fuel

Gas Code. ANSI Z223.1/NFPA 54, Section

5.3, Air for Combustion and Ventilation.

All spaces in homes fall into one of the three

following ventilation classications:

1. Unusually Tight Construction

2. Unconned Space

3. Conned Space

The information on pages 6 through 8 will help

you classify your space and provide adequate

ventilation.

4. Check installation of brick liners. Brick

liners are in four pieces: 2 sides, 1 back

and 1 top.

5. Place hood under top edge of rebox

opening. Use 3 screws from hardware kit

to mount hood to rebox (see Figure 3).

The air that leaks around doors and windows

may provide enough fresh air for combus-

tion and ventilation. However, in buildings of

unusually tight construction, you must provide

additional fresh air.

The National Fuel Gas Code, ANSI Z223.1/

NFPA 54 defines a confined space as a

space whose volume is less than 50 ft

per

1,000 Btu/hr (4.8 m

/kw) of the aggregate

input rating of all appliances installed in that

space and an unconned space as a space

whose volume is not less than 50 ft

per

1,000 Btu/hr (4.8 m

/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

unconned space.

* Adjoining rooms are communicating only if

there are doorless passageways or ventilation

grills between them.

Use this work sheet to determine if you have

a conned or unconned space.

 Includes the room in which you will install

replace plus any adjoining rooms with door-

less 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: Space size 16 ft. (length) x 14 ft.

(width) x 8 ft. (ceiling height) = 1792 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. 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: 1792 cu. ft. (volume of space) x 20

= 35,840 (maximum Btu/Hr the space can

support)

3. Add the Btu/Hr of all fuel burning appliances

in the space.

Vent-free replace _________ Btu/Hr

Gas water heater* _________ Btu/Hr

Gas furnace _________ Btu/Hr

Vented gas heater _________ Btu/Hr

Gas replace 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.

Example:

Gas water heater _________ Btu/Hr

Vent-free replace + _________ Btu/Hr

Total = _________ Btu/Hr

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: 35,840 Btu/Hr (maximum the

space can support)

40,000 Btu/Hr (actual amount of

Btu/Hr used)

30,000

10,000

40,000

www.desatech.com

119315-01C8

The space in the example is a conned 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

unconned space, remove door to adjoining

room or add ventilation grills between rooms.

See Ventilation Air From Inside Building.

B. Vent room directly to the outdoors. See

Ventilation Air From Outdoors.

C. Install a lower Btu/Hr replace, if lower Btu/Hr

size makes room unconned.

If the actual Btu/Hr used is less than the maximum

Btu/Hr the space can support, the space is an

unconned space. You will need no additional

fresh air ventilation.

IMPORTANT: Vent-free replaces add mois-

ture to the air. Although this is benecial,

installing replace in rooms without enough

ventilation air may cause mildew to form from

too much moisture. See Air for Combustion

Note: Your replace is designed to be used in

zero clearance installations. Wall or framing ma-

terial can be placed directly against any exterior

surface on the rear, sides or top of your replace,

except where standoff spacers are integrally at-

tached. If standoff spacers are attached to your

replace, these spacers can be placed directly

against wall or framing materials.

Note: When installing replace directly on

carpeting, tile or other combustible material,

other than wood ooring, the replace shall be

installed on a metal or wood panel extending

the full width and depth of the replace.

Use the dimensions shown for rough openings

to create the easiest installation (see Built-In

Fireplace Installation, page 10).

For propane/LP units, 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" of water. If you do not reduce

incoming gas pressure, replace regulator

damage could occur. Install external regula-

tor with the vent pointing down as shown in

Installation must include an 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, page 14).

IMPORTANT: Install equipment shutoff valve

in an accessible location. The equipment

shutoff valve is for turning on or shutting off

the gas to the appliance.

Check your building codes for any special

requirements for locating equipment shutoff

valve to replaces.

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 replace valves.

INSTALLATION

Continued

We recommend that you install a sediment

trap in supply line as shown in Figure 14. Lo-

cate sediment trap where it is within reach for

cleaning. Install in piping system between fuel

supply and heater. Locate sediment trap where

trapped matter is not likely to freeze. A sediment

trap traps moisture and contaminants. This

keeps them from going into replace controls.

If sediment trap is not installed or is installed

wrong, replace may not run properly.

* Purchase the optional CSA design-certied

equipment shutoff valve from your dealer. See

Accessories, page 34.
