PRODUCT FEATURES

OPERATION

This vent-free ﬁreplace 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 embers. When used without the optional blower, the ﬁreplace requires no electricity making it ideal for emergency backup heat.

SAFETY DEVICE

This ﬁreplace has a pilot with an Oxygen Depletion Sensing (ODS) safety shutoff system. The ODS/ pilot is a required feature for vent-free room heaters. The ODS/pilot system shuts off the ﬁreplace if there is not enough fresh air.

PIEZO IGNITION SYSTEM

This ﬁreplace has a piezo ignitor. This system requires no matches, batteries or other sources to light ﬁreplace.

WIRELESS REMOTE CONTROL

This ﬁreplace features an infrared wireless remote control. This control system can be used to auto matically light the pilot and adjust the burner ﬂame height at the push of a button.

WIRED WALL-MOUNTED REMOTE CONTROL

This ﬁreplace features a two-button wall switch assembly with glowing LEDʼs. The wall switch performs the same functions as the wireless handheld remote control with the added feature of LEDʼs for visual feedback of operation and status.

BLOWER ASSEMBLY

This ﬁreplace includes a blower assembly. The blower operates thermostatically. The blower circu lates heated air from the ﬁreplace into the room.

AIR FOR COMBUSTION

AND VENTILATION

WARNING: This heater shall not be installed in a conﬁned space or unusually tight construc tion 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.

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 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 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 the three criteria above, you must provide additional fresh air. See Ventilation Air From Outdoors page 7.

If your home does not meet all of the three criteria above, proceed to Determining Fresh-Air Flow for Fireplace Location.

Conﬁned Space 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 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 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 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.

Example: 57,600 Btu/Hr (maximum the space

can support)

73,000 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 ad ditional 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 heater may be oper ated 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,

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.

and tape paper template vertically onto mantel wall at preferred location. Pierce the paper at the centers of the 2 holes with a nail or sharp pencil, leaving a mark on the wall. Do the same at centers of the four circles near the corners of the rectangle.

8. Remove paper template from mantel wall.

9. Drill 1/8" pilot holes at each mark for top and bottom screw holes. Drill 3/8" holes at each mark for centers of four circles near corners of rectangle.

10. Using a straight edge and pencil, connect the outer edges of the 4 holes for the rectangle (see Figure 10, page 11). This will give you cutting lines for the rectangle you will cut in the mantel wall.

12. Carefully pass wall switch assembly through rectangular opening from inside mantel (see Figure 13).

13. Position wall switch assembly vertically over opening with decal lettering upright. Make sure wires freely pass through wall without binding. Align holes in wall plate with 1/8” pilot holes in mantel wall.

14. Drive mounting screws, removed in step 2 of Relocating Wall Switch Assembly on pages 10 and 11, through wall plate holes and into pilot holes in mantel wall.

15. Tighten screws until wall switch assembly is ﬁrmly attached to mantel. Do not over tighten.

INSTALLING GAS PIPING TO FIREPLACE LOCATION

WARNI N 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

Accessories, page 36.

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 14. 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 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 14).

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.

Continued

Apply pipe joint sealant lightly to male NPT threads. This will prevent excess sealant from go ing 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.

We recommend that you install a sediment trap in supply line as shown in Figure 15. 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 ﬁreplace gas controls. If sediment trap is not installed or is installed wrong, ﬁreplace may not run properly.

CAUTION: You must keep control areas, burners 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, 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 HOLDERS AND

PILOT AIR INLET HOLES

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 tubes 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 burners, pilot and primary air inlet holes on injector holder for dust and dirt (see Figures 45 and 46, page 26).

CLEANING AND

MAINTENANCE

Continued

3. Blow air through the ports/slots and holes in the burners.

4. Check the injector holders located at the end of the burner tubes 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 holders.

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 Figure 47). With the unit off, lightly blow air through the air inlet hole. The access hole for propane/LP pilot is on the front of the burner carriange as shown in Figure 47. The ac cess hole for natural pilot is behind the pilot bracket on the top of burner carriage (see Figure 47). You may blow through a drinking straw if compressed air is not available.
