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.
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 fuel­burning 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 4 through 6 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 per pa-sec-m2) or less with open­ings gasketed or sealed
b. weather stripping has been
added on openable windows and doors
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
From Outdoors
If your home does not meet all of the three criteria above, proceed to

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 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 HEATER 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 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:
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:
3. Add the Btu/Hr of all fuel burning appliances in the space. Vent-free heater _____________ 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.
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:
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 adjoining room. If the extra space provides an unconfined space, remove door to adjoin-
ing room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 6.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 6. C. Install a lower Btu/Hr heater, 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.
Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) = 2560 cu. ft. (volume of space)
2560 cu. ft. (volume of space) x 20 = 51,200 (maximum Btu/Hr the space can support)
Example:
Gas water heater 40,000 Btu/Hr Vent-free heater + 31,500 Btu/Hr Total = 71,500 Btu/Hr
51,200 Btu/Hr (maximum the space can support) 71,500 Btu/Hr (actual amount of Btu/Hr used)
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
105194

INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED OPERATION
Note:
When used as a vented heater, 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 manually-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 clear-
ance 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
21). This will insure vented operation (see Figure 10). The damper clamp will keep damper open. Installation instructions are included with clamp accessory.
See chart below for minimum permanent flue opening you must provide. Attach damper clamp so the minimum permanent flue opening will be maintained at all times.

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 heater 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.
Installation Items Needed
Before installing heater, make sure you have the items listed below.
• external regulator (supplied by installer, see above)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
* A CSA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection.
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, page 12).
IMPORTANT:
Install an 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 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 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 14, page 12. 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.
CAUTION: Avoid damage to control. Hold fitting with wrench when connecting it to gas piping and/or fittings.

LIGHTING
INSTRUCTIONS
WARNING:
If fireplace has glass doors, never operate this heater with glass doors closed. If you op­erate heater with doors closed, heat buildup inside fireplace will cause glass to burst. Also if fireplace opening has vents at the bottom, you must open the vents before operating heater.
You must operate this heater with a fireplace screen in place. Make sure fireplace screen is closed before running heater.
NOTICE: During initial operation of new heater, burning logs will give off a paper-burning smell. Open damper or window to vent smell. This will only last a few hours.
Note:
Home owners generally prefer to operate their heater with the chimney damper closed. This will put all the heat into the room. However, there may be times you will desire the full flames of the HI heat setting but will find the heat output excessive. You can open the chim­ney damper (if you have one) fully or partially to release some of the heat.
WARNING: Damper handle will be hot if heater has been running.
1. STOP! Read the safety information in column 1.
2. Make sure equipment shutoff valve is fully open.
3. Set switch in OFF position.
WARNING: Burner will come on automatically within one minute when the remote selector switch is in the ON position after the pilot is lit.
4. Press in and turn control knob clock­wise to the OFF position.
5. Wait f ive (5) minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow “B” in the safety in­formation, column 1. If you don’t smell gas, go to the next step.
6. Press in and turn control knob coun­terclockwise to the PILOT position. Press in control knob for five (5) seconds (see Figure 20).
Note:
You may be running this heater for the first time after hook­ing up to gas supply. If so, the con­trol knob may need to be pressed in for 30 seconds or more. This will al­low air to bleed from the gas system.

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.
CLEANING 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 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 26).
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 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 27). 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.

Always specify model and serial numbers when communicating with the factory. We reserve the right to amend these specifications at any time without notice. The only warranty applicable is our standard written warranty.
We make no other warranty, expressed or implied.
LIMITED WARRANTY
VENT-FREE PROPANE/LP GAS LOG HEATERS
Fireplace Manufacturers Incorporated 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.
This warranty is extended only to the original retail purchaser. This warranty covers the cost of part(s) required to restore this heater to proper operating condition and an allowance for labor when provided by a Fireplace Manufacturers Incorporated Authorized Service Center. Warranty part(s) MUST be obtained through authorized dealers of this product and/or Fireplace Manufacturers Incorporated who will provide original factory replacement parts. 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) YEARS ON ALL COMPONENTS AND FROM THE DATE OF FIRST PURCHASE; AND FIREPLACE MANUFACTURERS INCORPORATED’S LIABILITY IS HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND FIREPLACE MANUFACTURERS INCORPORATED SHALL NOT BE LIABLE FOR ANY OTHER DAMAGES WHATSOEVER INCLUDING INDIRECT, INCIDENTAL OR CONSEQUENTIAL 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. For information about this warranty write:
