AIR FOR COMBUSTION
VENTILATION
WARNING: This fireplace 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.
Today’s 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 7 through 9 will help you classify your space and provide adequate ventilation.
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 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 ar-
eas 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
doors
, page 8
If your home does not meet all of the three criteria above, proceed to
mining Fresh-Air Flow For Fireplace Lo­cation,
page 8.
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 m3 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 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 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:
(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:
35,840 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free fireplace _________ Btu/Hr
Gas water heater* _________ Btu/Hr
Gas furnace _________ Btu/Hr
Vented gas heater _________ 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 heater _________ Btu/Hr
Vent-free fireplace + _________ Btu/Hr
Total = _________ Btu/Hr
4. Compare the maximum Btu/Hr the space can sup­port with the actual amount of Btu/Hr used.
________
________
Example:
Space size 16 ft. (length) x 14 ft.
1792 cu. ft. (volume of space) x 20 =
30,000 10,000 40,000
Btu/Hr (maximum the space can support)
Btu/Hr (actual amount of Btu/Hr used)
35,840 Btu/Hr (maximum the space can support)
40,000 Btu/Hr (actual amount of Btu/Hr used)
The space in the 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, the space is an unconfined 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
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 4, page 9). You can also remove door into adjoining room (see option 3, Fig­ure 4, page 9). Follow the National Fuel Gas Code,
ANSI Z223.1/NFPA 54, Section 5.3, Air for Com­bustion and Ventilation for required size of ventila-
tion grills or ducts.
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:
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 21. Pointing the vent down protects it from freezing rain or sleet.
For natural gas, check gas line
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 22, page 18. 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 fireplace controls. If sediment trap is not installed or is installed wrong, fireplace may not run properly.
Propane/LP Supply Tank
External Regulator
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" or greater diame­ter 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 heater (see Figures 22).
IMPORTANT:
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 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.

OPERATING
BLOWER
This blower has three settings: ON, OFF, and AUTO. In the ON position, the blower will op­erate constantly. In the OFF position, the blower will not operate. In the AUTO position, the blower will start when the thermostat senses a sufficient increase in firebox temperature.
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.
Note:
It is safe to operate fireplace with blower 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 47 shows a correct pilot flame pattern. Figure 48 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 48
turn fireplace off (see To Turn Off Gas to Appli-
ance, page 25 for Thermostat-Controlled Mod­els or page 27 for Remote-Ready Models)
see Troubleshooting, page 31
Note:
The correct pilot flame on natural gas units will have a slight curve, but flame should be blue and have no yellow or orange color.

CLEANING AND
MAINTENANCE
WARNING: Turn off fireplace
and let cool before cleaning.
CAUTION: You must keep control areas, burner, 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, 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 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 as­sembly. There is a small pilot air inlet hole about two inches from where the pilot flame comes out of the pilot assembly (see Figures 52 or 53 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.
Ports/Slots
Injector Holder
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 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 51).
3. Blow air through the ports/slots and holes in the burner.
