OPERATION
This heater is clean burning. It requires no outside venting. There is no heat loss out a vent or up a chimney. Heat is generated by both realistic flames and glowing coals. This heater is designed for vent­free operation with flue damper closed. It has been tested and approved to ANSI Z21.11.2 standard for unvented heaters. State and local codes in some areas prohibit the use of vent-free heaters. This heater may also be operated as a vented decorative (ANSI Z21.60) product by opening the flue damper (Non-Thermostat Models Only).
SAFETY DEVICE
This heater has a pilot with an Oxygen Depletion Sensing (ODS) safety shutoff system. The ODS/pilot is a required feature for vent­free room heaters. The ODS/pilot shuts off the heater if there is not enough fresh air.
PIEZO IGNITION SYSTEM
This heater has a piezo ignitor. This system requires no matches, batteries, or other sources to light heater.
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 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 5 through 7 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 e xposed to the outside atmosphere
have a continuous water vapor retar der with a rating of one perm (6 x 10 openings gasketed or sealed
b. weather stripping has been added on openable win-
dows 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 pro vide additional fresh air . See
Air From Outdoors
If your home does not meet all of the three criteria above, proceed to
tion,
Determining Fresh-Air Flow For Heater Loca-
page 6.
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:
height) = 2560 cu. ft. (volume of space) If additional ventilation to adjoining room is supplied with grills or open-
ings, 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
Example:
Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.
* 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:
Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling
can support)
2560 cu. ft. (volume of space) x 20 = 51,200 (maximum
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
Example:
Gas water heater _____________ Btu/Hr Vent-free heater + _____________ Btu/Hr Total = _____________ Btu/Hr
51,200 Btu/Hr (maximum the space can support) 73,000 Btu/Hr (actual amount of Btu/Hr used)
40,000 33,000 73,000
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 ex-
tra space provides an unconfined space, remove door to adjoining room or add ventilation grills between rooms. See V entilation Air Fr om Inside Building, page 7.
B. Vent room directly to the outdoors. See Ventilation Air From Out-
doors, page 7.
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.
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

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 clearance to combustibles re-
quirements 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 31). This will insure vented operation (see Figure 10). The damper clamp will keep damper open. Installation instructions are included with clamp accessory.

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 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)
• 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. Purchase the optional CSA design-certified equipment shutoff valve from your dealer. See Accessories, page 31.
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 16. Pointing the vent down protects it from freezing rain or sleet.
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 17 or 18 page 14, depending on your model).
IMPORTANT:
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 Figures 17 or 18 page 14, depending on your model. 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 regulator. Hold gas regulator with wrench when connecting it to gas piping and/or fittings (Variable Manually-Controlled and Thermostat-Controlled Models Only).
CAUTION: Avoid damage to gas control. Hold gas fitting with wrench when connecting it to gas piping and/or fittings (Remote-Ready Models Only).
Install equipment shutoff valve in an accessible
External Regulator Propane/LP Supply Tank
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.
