AIR FOR COMBUSTION

AND VENTILATION

WARNING: This heater shall not be installed in confined 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.

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 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 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 classifications:

1. Unusually Tight Construction

2. Unconfined Space

3. Confined Space

The information on pages 6 through 8 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 continuous water vapor retarder with a rating of one perm (6 x 10-11 kg per pa-sec-m2) or 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 6.

If your home does not meet all of the three criteria above, proceed to Determining

Fresh-Air Flow For Appliance Location.

Confined and Unconfined Space

The National Fuel Gas Code, ANSI Z223.1/NFPA

54 defines a confined space as a space whose vol ume is less than 50 cubic feet per 1,000 Btu per hour

(4.8 m 3 per kw) of the aggregate 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 m 3 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 odorless passageways or ventilation grills between them.

DETERMINING FRESH-AIR FLOW

FOR APPLIANCE 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 appliance plus any adjoining rooms with doorless passageways or ventilation grills between the rooms.

114744-01B

AIR FOR COMBUSTION

AND VENTILATION

Continued

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 =

(Maximum 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 appliance _________Btu/Hr

Gas water appliance* _________Btu/Hr

Gas furnace _________Btu/Hr

Vented gas appliance _________Btu/Hr

Gas fireplace 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 appliance

Vent-free appliance

Total

_________Btu/Hr

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

73,000 Btu/Hr (actual amount of

Btu/Hr used)

The space in the previous 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.

B. Vent room directly to the outdoors. See Ven- tilation Air From Outdoors, page 8.

C. Install a lower Btu/Hr appliance, 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 appliance 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.

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 on page 8). 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.

ACCESSORY FOR VENTED

OPERATION

Note: When used as a vented decorative, appliance must be installed only in a solid-fuel burning fireplace with a working flue and constructed of noncombustible material.

If your heater is a non-thermostatically-controlled model, you may use this heater as a vented product.

There are three reasons for operating your heater in the vented mode.

1. The fireplace does not meet the clearance to combustibles requirements for vent-free operation.

2. State or local codes do not permit vent-free operation.

3. You prefer vented operation.

If reasons number 1 or 2 above apply to you, you must permanently open chimney flue damper. You must install the damper clamp accessory (to order, see Accessories, page 27). This will insure vented operation (see Figure 10). The damper clamp will keep damper open. Installation instructions are included with clamp accessory.

WARNING: If installing in a sunken fireplace, special care is needed. You must raise the fireplace floor to allow access to heater control panel. This will insure adequate air flow and guard against sooting. Raise fireplace floor with noncombustible material. Make sure material is secure.

CONNECTING TO GAS SUPPLY

WARNING: This appliance requires a 3/8" 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: Do not pick up heater assembly by logs. This could damage unit. Only handle assembly by grates.

IMPORTANT: Make sure the heater burner is level. If heater is not level, heater will not work properly.

Installation Items Needed

• control cover kit (optional - see Accessories, page 27)

• approved flexible gas hose and fittings (provided with heater) (if allowed by local codes)

• sealant (resistant to propane/LP gas, not provided)

Note: Install optional GHRCTB Receiver and

Hand-Held Remote Control Kit (see Accessories, page 27) before installing gas log heater. See installation instructions included with the kit.

1. Apply pipe joint sealant lightly to male threads of gas fitting (not provided). Connect approved flexible gas hose to inlet side of gas control (see Figure 12).

2. Position heater assembly in fireplace.

3. Connect to gas supply. See Connecting To

Gas Supply.

Gas Control Valve

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

WARNING: Never connect natural gas fireplace to private

(non-utility) gas wells. This gas is commonly known as wellhead gas.

Installation Items Needed

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

• external regulator (supplied by installer for propane/LP models only)

• piping (check local codes)

• sealant (resistant to propane/LP gas)

• equipment shutoff valve *

• test gauge connection *

• sediment trap

• tee joint

• pipe wrench

• approved flexible gas line with gas connector

(if allowed by local codes) (provided)

* 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 27.

Flexible Gas Hose

(if allowed by local codes)

INSTALLATION

Continued

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 pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 13. 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.

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).

IMPORTANT: Install equipment shutoff valve in an accessible location within 6 feet of the appliance. The equipment shutoff valve is for turning on or shutting off the gas to the appliance.

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.

INSPECTING BURNER

Check pilot flame pattern and burner flame patterns often.

PILOT FLAME PATTERN

Figure 23 shows a correct pilot flame pattern.

Figure 24 shows an incorrect pilot flame pattern.

The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.

If pilot flame pattern is incorrect, as shown in

Figure 24

• turn heater off (see To Turn Off Gas to Appli-

ance, page 18)

• see Troubleshooting, page 22

Note: The pilot flame on natural gas units will have a slight curve, but flame should be blue and have no yellow or orange color.

Pilot Burner

If burner flame pattern is incorrect, as shown in

Figure 26

• turn heater off (see To Turn Off Gas to Appli-

ance, page 18)

• see Troubleshooting, page 22

The flames from the burner travel horizontally through the log set and emerge at the middle and rear of the set against the back logs.

The flames are blue off the burner and as they progress through the log set, change to a light yellow color, yellow decorative flames are visible as the flames exit the log set.

The base of the log set and the underside of the top logs glow red. Natural gas models will burn with more blue flame, while propane gas model will burn with bright yellow flame.

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, pet hair, bedding material, etc.

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 opening on the injector holder.

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

Clean the pilot assembly also. A yellow tip on the pilot flame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about two inches from where the pilot flame comes out of the pilot assembly (see Figure 29). With the unit off, lightly blow air through the air inlet hole in the same direction as gas flow. You may blow through a drinking straw if compressed air is not available.

Ports

Slots

Injector

Holder

WARNING: Failure to keep the primary air openings of the burner clean may result in sooting and property damage.

BURNER INJECTOR HOLDER AND

PILOT AIR INLET HOLE

The primary air inlet openings 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 openings prior to each heating season. Blocked air openings 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 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 opening on injector holder for dust and dirt

(see Figure 28).

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

LIMITED WARRANTY

VENT-FREE GAS LOG HEATERS

DESA warrants this product to be free from defects in materials and components for four (4) years 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.

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 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE TO FOUR (4)

HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND DESA SHALL NOT BE LIABLE

FOR ANY OTHER DAMAGES WHATSOEVER INCLUDING INDIRECT, INCIDENTAL OR CONSE-

QUENTIAL 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.
