AIR FOR COMBUSTION

AND VENTILATION

WARNING: This ﬁreplace shall not be installed in a conﬁned space or unusually tight

construction unless provisions are provided for adequate com bustion 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.

AIR FOR COMBUSTION

AND VENTILATION

Continued

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 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 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 these three

criteria, you must provide additional fresh air. See Ventilation Air From Outdoors, page 8.

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

www.desatech.com

Conﬁned and Unconﬁned Space

The National Fuel Gas Code, ANSI Z223.1/NFPA 54 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 unconﬁned space as a space whose volume is not 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. Rooms com

municating 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 passageways or ventilation grills between them.

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 ﬁreplace 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 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.

Example: 35,840 Btu/Hr (maximum the space

can support)

40,000 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 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 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 ﬁreplace 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

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 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 4). You can also remove door into adjoining room (see option 3, Figure 4). 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.

Figure 4 - Ventilation Air from Inside

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 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.

CONNECTING TO GAS SUPPLY

WARNING: This appliance requires a 45° male ﬂare ﬁtting 5/8”-18 UNF (Uniﬁed National Fine Thread) inlet connection and the ﬂexible gas line provided.

WARNING: A qualiﬁed service person must connect ﬁreplace to gas supply. Follow all local codes.

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:

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 ﬁreplace valves.

Install equipment shutoff valve

WARNING: Never connect natural gas ﬁreplace to private (non-utility) gas wells. This gas is commonly known as wellhead gas.

IMPORTANT: For natural gas, check gas line pressure before connecting ﬁreplace to gas line. Gas line pressure must be no greater than 14 inches of water. If gas line pressure is higher, heater regulator damage could occur.

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.

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, ﬁreplace 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 cer

tain areas. Check your local codes. Use pipe of 1/2" or greater diameter to allow proper gas volume to ﬁre

place. If pipe is too small, undue loss of volume will occur.

OPERATING FIREPLACE

Continued

Note: Do not leave the hand-held remote in the

AUTO mode close to the ﬁreplace. The radiant heat from the ﬁreplace will turn off the ﬁreplace. Ideally, place the hand-held remote in the center of the room facing towards the ﬁreplace.

Note: Do not hold the hand-held remote for a long time. Body temperature will affect its operation in the AUTO mode.

Safety Features

When away from home for an extended period of time or as a child safety feature to prevent accidental ignition of the ﬁreplace, the receiver ON/OFF/REMOTE switch should be in the OFF position.

Auto Shutoff Feature

1. If the average room temperature exceeds 82 degrees Fahrenheit (28 degrees Centi grade), the hand-held remote control will perform a safety override and shut the ﬁreplace off. This feature is not available in the MANU mode.

2. The receiver continuously receives signals from the hand-held remote to control the room temperature. If the hand-held remote is misplaced, obstructed or for any reason cannot transmit to the receiver, the receiver will shut off the ﬁreplace after 8 minutes.

Key Pad Lock Feature

This feature allows the user to lock/unlock the keypad on the hand-held remote in the MANU or AUTO mode to prevent inadvertent operation (i.e. children operating the hand-held remote control, etc.). The keypad is locked in either on or off. Press the POWER and LOCK buttons together to turn the unit on or off.

OPTIONAL GWMT1 WALL

MOUNTED THERMOSTAT

Make sure the heater switch is on AUTO and set the temperature adjustment on wall thermostat to the desired setting. The thermostat has been electronically calibrated at the factory and re quires no adjustment or leveling.

Upon installation, the thermostat must be al lowed to stabilize at room temperature for a minimum of 30 minutes for proper operation. See installation instructions on pages 19 and 20.

OPTIONAL GWMS2 WALL

MOUNTED SWITCH

Make sure the heater switch is on AUTO. This wall switch works just like the conventional light switch. Flip the switch up for on and down for off.

Note: Make sure that this switch is not in a posi tion to be mistaken for a light switch. This may result in the ﬁreplace being inadvertently turned on without the proper precautions being taken. See installation instructions on page 19.

OPERATING

BLOWER

Note: Your ﬁreplace and thermostat blower

will not turn on and off at the same time. The

ﬁreplace may run for several minutes before the blower turns on. After the heater modulates to the pilot position, the blower will continue to run. The blower will shut off after the ﬁrebox temperature decreases.

It is safe to operate ﬁreplace with blower

Note:

turned off. However, the blower helps distribute heated air from the ﬁreplace.

INSPECTING BURNERS

Check pilot ﬂame pattern and burner ﬂame patterns often.

PILOT FLAME PATTERN

Figure 46 shows a correct pilot ﬂame pattern. Figure 47 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 ﬁreplace will shut down.

If pilot ﬂame pattern is incorrect, as shown in Figure 47

• turn ﬁreplace off (see To Turn Off Gas to Appli ance, page 22 for Thermostat-Controlled Mod els or page 24 for Remote-Ready Models)

• see Troubleshooting

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.

BURNER FLAME PATTERN

Figure 48 shows a correct burner ﬂame pattern. Figure 49 shows an incorrect burner ﬂame pattern. The incorrect burner ﬂame pattern shows sporadic, irregular ﬂame tipping. The ﬂame should not be dark or have an orange/reddish tinge.

Note: When using the ﬁreplace the ﬁrst time, the ﬂame will be orange for approximately one hour until the log cures.

If burner ﬂame pattern is incorrect, as shown in Figure 49

• turn ﬁreplace off (see To Turn Off Gas to Appli ance, page 22 for Thermostat-Controlled Mod els or page 24 for Remote-Ready Models)

CLEANING AND

MAINTENANCE

WARNING: Turn off ﬁreplace

and let cool before cleaning.

CAUTION: You must keep control areas, burner and cir culating air passageways of ﬁreplace clean. Inspect these areas of ﬁreplace before each use. Have ﬁreplace inspected yearly by a qualiﬁed service person. Fireplace may need more frequent cleaning due to excessive lint from carpeting, pet hair, bedding material, 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 ﬁreplace 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.

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 50).

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.

Clean the pilot assembly also. A yellow tip on the pilot ﬂame indicates dust and dirt in the pilot as sembly. There is a small pilot air inlet hole about two inches from where the pilot ﬂame comes out of the pilot assembly (see Figures 51 or 52 depending on model). With the unit off, lightly blow air through the air inlet hole. You may blow through a drinking straw if compressed air is not available.

LOG SET

• If you remove one-piece log set for cleaning, refer to Installing Log Set and Screen, page 21, for placement instructions.

• Replace log set if broken or chipped (dime-sized or larger).

CABINET

Air Passageways

• Use a vacuum cleaner or pressurized air to clean.

Exterior

• Use a soft cloth dampened with a mild soap and water mixture. Wipe the cabinet to remove dust.
