AIR FOR COMBUSTION

AND VENTILATION

WARNING: This heater shall not be installed in a 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 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 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

Fresh-Air Flow For Fireplace Location.

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 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.

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 18 ft.

(width) x 8 ft. (ceiling height) = 2880 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: 2880 cu. ft. (volume of space) x 20 =

57,600 (maximum Btu/Hr the space can support)

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

Vent-free ﬁreplace ___________ Gas water heater* ___________ Gas furnace ___________ Vented gas heater ___________ Gas ﬁreplace logs ___________ Other gas appliances* + ___________ Total = ___________ * Do not include direct-vent gas appliances. Di

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,

the space is an unconﬁned 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 or applicable local codes.

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 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 3). You can also remove door into adjoining room (see

option 3, Figure 3). 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.

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: 57,600 Btu/Hr (maximum the space

can support)

73,000 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, page 8.

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.

WARNING: Failure to position the parts in accordance with supplied diagrams or failure to use only parts speciﬁcally approved with this heater may result in damage or personal injury.

WARNIN G : A qu a li f ie d service person must connect ﬁreplace to gas supply. Follow all local codes.

If any of the original wire as supplied with the appliance must be replaced, it must be replaced with 105˚C wire or it's equivalent.

Operating the Blower

After ﬁnal installation of your ﬁreplace, light your gas appliance with the blower off. After about 15 minutes, turn the blower on to deliver heated air at the top louvers. The blower features a variable control which allows you to select the speed you desire. In the OFF position, the blower will not operate. In the ON position, the blower will start when the thermostat senses a sufﬁcient increase in ﬁrebox temperature (approximately 10 to 20 minutes depending on heat setting).

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

Note: Periodically check the louvers of the ﬁrebox and remove any dust, dirt or other obstructions.

INSTALLING GAS PIPING TO FIREPLACE LOCATION

WARNIN G : A qu a li f ie d service person must connect ﬁreplace to gas supply. Follow

all local codes.

WARNING: For propane/LP units, never connect ﬁreplace directly to propane/LP supply. This ﬁreplace requires an external regulator (not supplied). Install the external regulator between the heater and propane/LP supply.

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

Installation Items Needed

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

• external regulator (supplied by installer, for propane/LP units 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) (not 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

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 24, page 18. Pointing the vent down protects it from freezing rain or sleet.

Accessories, page 40.

INSTALLATION

Continued

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 ﬁreplace. 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 ﬁreplace (see Figure 24).

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 ﬁreplace valves. Never use sealant on ﬂare threads.

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

Propane/LP Supply Tank

We recommend that you install a sediment trap in supply line as shown in Figure 25. Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and ﬁreplace. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into ﬁre place gas controls. If sediment trap is not installed or is installed wrong, ﬁreplace may not run properly.

OUTAGE

WARNING: You must operate this heater with the ﬁreplace screen in place. Make sure ﬁre place screen is in place before running heater.

Because this ﬁreplace has an electronic ignition system, in the event there is a loss of power, it will be necessary to manually light the pilot with the piezo ignitor. After the pilot is lit, the main burner will light automatically.

1. Follow steps 1 through 3 under Normal Lighting Instructions, page 26.

2. Set manual ignition bypass switch on con trol panel to ON position (manual ignition position). See Figure 50.

3. The pilot is attached to the rear of the front burner. You will be able to see the pilot and spark electrode without removing the screen or logs.

4. Place the magnetic manual override handle, provided with this unit, on the end of the gas valve stem (see Figure 50).

5. Turn the override handle fully counter clockwise to the PILOT position. The handle will not stop but will begin to slip when you have fully turned to the PILOT position.

6. While holding the valv e hand le in the PILOT position, press and release piezo ignitor button (see Figure 50). This will light the pilot. If needed, keep pressing ignitor button until pilot lights.

7. When pilot ﬂame is lit, hold manual over ride handle until thermocouple heats (ap proximately 5 to 15 seconds). If pilot goes

out, repeat process. If several attempts to light the pilot fail, contact a qualiﬁed service person or gas supplier for repairs.

Shutting Off Heater When Manually Lit

Set manual ignition bypass switch on control panel to OFF (automatic ignition position). This will cause the controls to shut down the ﬁreplace.

OPTIONAL BLOWER

OPERATION

Locate the blower switch by opening lower louver on ﬁreplace. Blower switch is located at lower right inside louver door.

The GA3650T/GA3700T Series thermostatcontrolled blower has a variable speed control with an ON/OFF switch. The blower will start when the thermostat senses a sufﬁcient increase in ﬁrebox temperature. The GA3700/GA3750 Series vari ab le speed blow er also has an ON/OFF switch built into the variable speed control.

Note for GA3650T/GA3700T Series Only: If you are using this series blower, your ﬁreplace and 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.

Note: It is safe to operate ﬁreplace with blower turned off. However, the blower helps distribute heated air from the ﬁreplace.

Follow installation instructions included with the blower accessory.

INSPECTING BURNERS

Check pilot ﬂame pattern and burner ﬂame patterns often.

PILOT FLAME PATTERN

Figure 51 shows a correct pilot ﬂame pattern. Figure 52 shows an incorrect pilot ﬂame pattern. The incorrect pilot ﬂame is not properly heating the thermocouple. When the thermocouple cools, the heater will shut down.

If pilot ﬂame pattern is incorrect, as shown in Figure 52

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

ance, page 27 or 28 depending on situation)

• 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.

MAIN BURNER

Periodically inspect all burner ﬂame holes with the heater running. All slotted burner ﬂame holes should be open with 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 may create soot.

CLEANING AND

MAINTENANCE

WARNING: Turn off ﬁreplace

and let cool before cleaning.

CAUTION: You must keep control areas, burners and circulating 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, bedding material, pet hair, etc.

BURNER INJECTOR HOLDER

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 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

53).

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.

PILOT AIR INLET HOLE

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 Figure 54). 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. You may also clean the pilot air inlet hole by pushing a common pipe cleaner completely through the air inlet hole once.
