AIR FOR COMBUSTION

AND VENTILATION

WARNING: This heater shall

not be installed in a conned 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 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 appliances 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.

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.

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 5 through 7 will help you classify your space and provide adequate ventilation.

113896-01D 5

AIR FOR COMBUSTION

AND VENTILATION

Continued

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 dened 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 less with openings 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 oors, 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 Ventilation Air From Outdoors, page 7.

If your home does not meet all of the three

criteria above, proceed to Determining Fresh-Air Flow For Fireplace Location.

Conned and Unconned Space

The National Fuel Gas Code, ANSI Z223.1 denes a conned 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 unconning 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 unconned space.

* Adjoining rooms are communicating only if

there are doorless

DETERMINING FRESH-AIR FLOW FOR FIREPLACE LOCATION

Determining if You Have a Conned or Unconned Space

Use this work sheet to determine if you have a conned or unconned 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: 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. 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: 2560 cu. ft. (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.

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. Di-

rect-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.

_________

_________ Example: 51,200 Btu/Hr (maximum the space

56,000 Btu/Hr (actual amount of

Btu/Hr (maximum the space can support)

AND VENTILATION

Continued

The space in the above example is a conned 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:

A. Rework worksheet, adding the space of an adjoin-

ing 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 Ventila-

tion 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 un-

conned space. You will need no additional fresh

air ventilation.

WARNING: If the area in

which the heater may be operated is smaller than that dened as an unconned 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, ANSI Z223.1/NFPA 54 Section 5.3

or applicable local codes.

Figure 2 - Ventilation Air from Inside

Building Shown with Optional Mantel

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent openings: one within 12" of the ceiling and one within 12" of the oor. Connect these items directly to the

outdoors or spaces open to the outdoors. These

spaces include attics and crawl spaces. Follow the

National Fuel Gas Code ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation for

required size of ventilation grills or ducts. IMPORTANT: Do not provide openings for inlet

or outlet air into attic if attic has a thermostatcontrolled power vent. Heated air entering the attic will activate the power vent.

VENTILATION AIR

Ventilation Air From Inside Building

This fresh air would come from an adjoining un-

conned space. When ventilating to an adjoining

unconned space, you must provide two perma-

nent openings: one within 12" of the ceiling and

one within 12" of the oor 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 ANSI Z223.1/NFPA 54, Section 5.3, Air for

Combustion and Ventilation for required size of

ventilation grills or ducts.

CONNECTING TO GAS SUPPLY

WARNING: This appliance requires a 1/2" NPT (National Pipe Thread) inlet connection to the pressure regulator.

WARNING: A qualied service person must connect heater to gas supply. Follow all local codes.

CAUTION: Never connect propane/LP replace directly to the propane/LP supply. This replace requires an external regulator (not supplied). Install the external regulator between the replace and propane/LP supply.

Installation Items Needed

Before installing replace, make sure you have the items listed below.

• external regulator (supplied by installer)

• piping (check local codes)

• sealant (resistant to propane/LP gas)

• equipment shutoff valve *

• ground joint union

• sediment trap

• tee joint

• pipe wrench

• test gauge connection *

* A CSA design-certied equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the optional CSA design-certied equipment shutoff valve from your dealer. See Accessories, page 27.

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, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 19. Pointing the vent down protects it from freezing rain or sleet.

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 1/2" diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of volume will occur.

WARNING: Never connect

natural gas replace to private (non-utility) gas wells. This gas is commonly known as

Propane/LP Supply Tank

External Regulator

wellhead gas.

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 20).

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 heater valves.

WARNING: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.

We recommend that you install a sediment trap in

supply line as shown in Figure 20. Locate 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 heater controls. If sediment trap is not installed or is installed wrong, heater may not run properly.

BURNER PRIMARY AIR HOLES

Air is drawn into the burner through the holes in the tting at the burner entrance. These holes may become blocked with dust or lint. Periodically inspect these holes for any blockage and clean if needed. Blocked air holes will create soot.

MAIN BURNER

Periodically inspect all burner ame holes with the heater running. All slotted burner ame holes should be open with yellow ame present. All round burner ame holes should be open with a small blue ame present. Some burner ame holes may become blocked by debris or rust, with no ame present. If so, turn off heater and let cool. Remove blockage. Blocked burner ame holes will create soot.

CLEANING AND

MAINTENANCE

WARNING: Turn off heater

and let cool before cleaning.

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 qualied service person. Heater may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.

WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property damage.

BURNER INjECTOR HOLDER AND PILOT AIR INLET HOLE

The primary air inlet holes allow the proper amount of air to mix with the gas. This provides a clean burning ame. Keep these holes clear of dust, dirt, lint and pet hair. 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 qualied service person.

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 and primary air inlet holes on injector holder for dust and dirt (see Figure 34).

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

the burner.

4. Check the injector holder located at the end of the burner tube again. Remove any large particles of dust, dirt, lint or pet hair with a soft cloth or vacuum cleaner nozzle.

5. Blow air into the primary air holes on the

injector holder.

6. In case any large clumps of dust have now been pushed into the burner repeat steps 3 and 4.

VENT-FREE GAS BAY FRONT FIREPLACE

DESA Heating Products warrants this product to be free from defects in materials and components for two (2) years from the date of rst purchase, provided that the product has been properly installed, operated and maintained in accordance with all applicable instructions.

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 replace MUST be installed by a qualied 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 replace 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 ON ALL COMPONENTS FROM THE DATE OF FIRST PURCHASE; AND DESA HEATING PRODUCTS’ 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, INCIDENTAL OR CONSEQUENTIAL DAMAGES.

damages may not apply to you.

This warranty gives you specic legal rights and you may also have other rights that vary from state to state.
