AIR FOR COMBUSTION

AND VENTILATION

WARNING: This heater shall not be installed in a conﬁned space or unusually tight con struction unless provisions are provided for adequate combus tion and ventilation air. Read the following instructions to insure proper fresh air for this and other fuel-burning appliances in your home.

Todayʼs 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 efﬁ 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, 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 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 fol lowing ventilation classiﬁcations:

1. Unusually Tight Construction

2. Unconﬁned Space

3. Conﬁned Space

The information on pages 5 through 7 will help you classify your space and provide adequate ventilation.

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 deﬁned 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 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 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.

Conﬁned and Unconﬁned Space

The National Fuel Gas Code, ANSI 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 m per kw) of the aggregate input rating of all appliances installed in that space and an unconﬁning 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.

* Adjoining rooms are communicating only if there are doorless

DETERMINING FRESH-AIR FLOW FOR FIREPLACE 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: Includes the room in which you will install heater 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 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.

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 adjoin

ing 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.

B. Vent room directly to the outdoors. See Ventila

tion Air From Outdoors.

C. Install a lower Btu/Hr ﬁreplace, 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, conﬁned 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, ANSI Z223.1/NFPA 54 Section 5.3 or applicable local codes.

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 ﬂoor. 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 conﬁned space. When ventilating to an adjoining unconﬁned space, you must provide two perma nent 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 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 qualiﬁed service person must connect heater to gas supply. Follow all local codes.

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

Installation Items Needed

Before installing ﬁreplace, 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-certiﬁed equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the optional CSA design-certiﬁed equipment shutoff valve from your dealer. See

Accessories, page 32.

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 inches of water. If you do not reduce incoming gas pres sure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 20. 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 ﬁreplace to private (non-utility) gas wells. This gas is commonly known as 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 21).

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 re quirements for locating equipment shutoff valve to ﬁreplaces.

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 21. 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 ﬁtting 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 ﬂame holes with the heater running. All slotted burner ﬂame holes should be open with yellow ﬂame present. All round burner ﬂame holes should be open with a small blue ﬂame present. Some burner ﬂame holes may become blocked by debris or rust, with no ﬂame present. If so, turn off heater and let cool. Remove blockage. Blocked burner ﬂame 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 qualiﬁed 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 ﬂame. 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 qualiﬁed 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 com pressed air in a can, please follow the directions on the can. If you donʼt follow directions on the can, you could damage the pilot assembly.

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.

Failure to use original factory replacement parts voids this warranty. The ﬁreplace 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.

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 INTERNATIONALʼS LIABILITY IS HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND DESA INTERNA TIONAL SHALL NOT BE LIABLE FOR ANY OTHER DAMAGES WHATSOEVER INCLUDING INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES.
