PLANNING

Plan where you will install the rebox. This will save time and money later when you install the rebox. Before installation, consider the following:

1. Where the rebox will be located. Allow for wall and ceiling clearances (see Installa- tion Clearances, page 9).

Everything needed to complete installation.

3. This model CANNOT be installed in a bedroom or bathroom.

4. Proper air for combustion and ventilation.

5. Consider a location where heat output would not be affected by drafts, air condition ducts, windows or doors.

6. A location that minimizes modications on existing framing will make installation

easier.

Projected installations can extend any

distance into the room. A projection may be ideal as a partition between two otherwise common areas when added to an existing, nished wall (see Figure 2).

AIR FOR COMBUSTION AND VENTILATION

WARNING: This heater shall not be installed in a room or space unless the required volume of indoor combustion air is provided by the method described in the National Fuel Gas

Code, ANSI Z223.1/NFPA 54, the International Fuel Gas Code, or

applicable local codes. 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 efcient 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

efcient, your home needs to breathe. Fresh air must enter your home. All fuel-burning ap-

pliances need fresh air for proper combustion and ventilation.

Exhaust fans, reboxes, 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 ANS Z223.1/NFPA 54,Air for Combustion and Ventilation.

All spaces in homes fall into one of the three

following ventilation classications:

1. Unusually Tight Construction

2. Unconned Space

3. Conned 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 dened 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 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 oors, 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 8.

If your home does not meet all of the three

criteria above, proceed to Determining Fresh-Air Flow for Firebox Location,

page 7.

Conned and Unconned Space

The National Fuel Gas Code ANS Z223.1/ NFPA 54 denes a conned space as a space

whose volume is less than 50 cubic feet per 1,000 Btu/hr (4.8 m

input rating of all appliances installed in that

space and an unconned space as a space whose volume is not less than 50 cubic feet per 1,000 Btu/hr (4.8 m3 per kw) of the ag-

gregate 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 unconned space.

This heater shall not be installed in a conned

space or unusually tight construction unless

provisions are provided for adequate combus-

tion and ventilation air.

* Adjoining rooms are communicating only if there are doorless passageways or ventilation grills between them.

DETERMINING FRESH-AIR FLOW FOR FIREBOX LOCATION

Determining if You Have a Conned or Unconned Space

Use this work sheet to determine if you have a conned or unconned 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: Space size 22 ft. (length) x 18 ft.

(width) x 8 ft. (ceiling height) = 3168 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: 3168 cu. ft. (volume of space) x 20

= 63,360 (maximum Btu/Hr the space can

support)

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

Gas water heater* __________ Btu/Hr Gas furnace __________ Btu/Hr Vented gas heater __________ Btu/Hr Gas replace 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 Gas rebox logs + _________ Btu/Hr

Total = _________ Btu/Hr

40,000 39,000 79,000

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: 63,36 0 Btu/Hr (maximu m the

space can support)

79,000 Btu/Hr (actual amount of

Btu/Hr used)

The space in the above example is a conned

space because the actual Btu/Hr used is more than the maximum Btu/Hr the space can sup-

port. You must provide additional fresh air. Your options are as follows:

A. Rework work sheet, adding the space

of an adjoining room. If the extra space provides an unconned space, remove door to adjoining room or add ventilation grills between rooms. See Ventilation Air from Inside Building, page 8.

B. Vent room directly to the outdoors. See

Ventilation Air from Outdoors, page 8.

C. Install a lower Btu/Hr gas log heater, if

lower Btu/Hr size makes room unconned.

If the actual Btu/Hr used is less than the

maximum Btu/Hr the space can support, the space is an unconned space. You will need

no additional fresh air ventilation.

WARNING: If the area in which

the heater may be operated does not meet the required volume for

indoor combustion air, combustion and ventilation air shall be

provided by one of the methods

described in the National Fuel Gas Code, ANSI Z223.1/NFPA 54, the International Fuel Gas Code,

or applicable local codes.

Ventilation Air From Inside Building

This fresh air would come from an adjoining unconned space. When ventilating to an adjoining unconned space, you must provide two permanent openings: one within 12" of the ceiling and one within 12" of the oor on the wall connecting the two spaces (see option 1, Figure 3). You can also remove door into adjoining room (see option 2, Figure 3). Follow the National Fuel Gas Code ANS Z223.1/

NFPA 54 Air for Combustion and Ventilation

for required size of ventilation grills or ducts.

Figure 3 - Ventilation Air from Inside

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 oor. Connect these

items directly to the outdoors or spaces open to the outdoors. These spaces include at-

tics and crawl spaces. Follow the National Fuel Gas Code ANS Z223.1/NFPA 54 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 thermo-

stat-controlled power vent. Heated air entering the attic will activate the power vent.

CAUTION: Log heaters in-

stalled in this rebox create warm air currents. These currents move heat to wall surfaces next to rebox. Installing rebox next to vinyl or cloth wall coverings or operating rebox where impurities (such

as, but not limited to, tobacco smoke, aromatic candles, clean-

ing uids, oil or kerosene lamps, etc.) in the air exist, may discolor walls or cause odors.

IMPORTANT: Vent-free gas log heaters add moisture to the air. Although this is benecial, installing rebox in rooms without enough ventilation air may cause mildew to form from

too much moisture. See Air for Combustion and Ventilation, page 6.

IMPORTANT: Make sure the rebox is level.

If rebox is not level, log set will not work

properly.

Note: Your rebox is designed to be used in

zero clearance installations. Wall or framing material can be placed against any exterior surface on the rear, sides or top of your

rebox, except where standoff spacers are

integrally attached. If standoff spacers are

attached to your rebox, these spacers can be placed directly against wall or framing

materials.

Use dimensions shown for rough openings

to create the easiest installation (see Built-In Firebox Installation, page 9).

Mantel Clearances for Built-In Installation

If placing custom mantel above built-in rebox, you must meet the minimum allowable clearance between mantel shelf and top of rebox opening shown in Figure 7. These are the minimum allowable mantel clearances

for a safe installation. Use larger clearances

wherever possible to minimize the heating of objects and materials placed on the mantel.

CAUTION: Do not allow the

vent-free gas log heater to touch

or extend beyond the rebox screen.

If your installation does not meet the above

minimum clearances in Figure 7, you must:

• raise the mantel to an acceptable height,

• remove the mantel.

BUILT-IN FIREBOX INSTALLATION

Built-in installation of this rebox involves installing rebox into a framed-in enclosure. This makes the front of rebox ush with wall. Optional perimeter brass trim accessories are available (see Accessories, page

17). The brass trim will extend past sides of rebox approximately 1/2". This will cover the rough edges of the wall opening. If installing a mantel above the rebox, you must follow the clearances shown in Figure 7. Follow the instructions below to install the rebox in this

manner.

1. Frame in rough opening. The firebox framing should be constructed of 2 x 4 lumber or heavier. Construct framing

using dimensions shown in Figure 8 and 9, page 11. It is recommended that the framing be constructed rst and the unit

be placed in position by removing the

nailing anges from one side. After sliding the unit into place, the outer most anges

may be replaced and nailed to the framing

on all sides before applying the wallboard

to the exterior framing.

2. If the vent-free rebox is to be installed directly on carpeting, tile (other than ce-

ramic) or any combustible material other

than wood ooring; the vent-free rebox must be installed upon a metal or wood panel extending the full width and depth of the vent-free rebox.

3. If a raised platform is to be constructed,

ceiling clearances must be maintained.

WARNING: A qualied service person must connect heater to gas supply. Follow all local codes.

IMPORTANT: See Connecting to Gas Supply

in your log set owner’s manual for details on

gas hookup.

You may run the gas line from either side of the rebox (see Figure 11, page 12). When you have determined how the gas line will run,

locate one of the recessed knockouts in the

rebrick oor (see Figure 12, page 12). Firmly tap the center of the knockout with a chisel

until it is released. Carefully chisel the rough edges of the hole you have made to smooth

edges. This hole will line up with the hole in the metal oor.

INSTALLATION

Continued

CAUTION: Do not use exces-

sive force to remove the knock-

out. Too much force may damage the rebrick concrete insert.

A manual shutoff valve, complying with the

National Fuel Gas code, ANS Z223.1/NFPA 54, must be included within 6' of the vent-

free rebox gas supply system. It may be

convenient to install the gas shutoff outside

the vent-free rebox enclosure where it can be accessed with a key through a wall as shown in Figure 13. Depending on the type of installation, some local codes may require

you to install 2 manual shutoff valves independently accessible from both rooms. Check your local codes for applicable installation

requirements. A 36" long 1/2" NPT SCHD 40 exible gas

connector line complying with the National Fuel Gas code ANS Z223.1/NFPA 54, may

be run from the regulator to the incoming 1/2"

NPT black iron gas line. You may also route

the incoming 1/2" NPT black iron gas line directly to the appliance regulator.

The incoming gas line may be routed into the

vent-free rebox either from the left or right

hand sides (see Figure 11). Remove the gas

line cover plate from the vent-free rebox’s

outer surround at the location to be used. If a sediment trap is not incorporated as a part

of the gas utilization equipment, one shall be installed as close to the inlet of the equipment as practical at the time of installation, as per

ANS Z223.1/NFPA 54. See Figure 14.

INSTALLATION

Continued

Prepare incoming black iron gas line with Teon tape or pipe joint compound (check with local codes as to the use of Teon tape). Compounds used on threaded joints of gas piping

shall be resistant to the action of propane/LP and should be applied lightly to ensure excess sealant does not enter the gas line.

Complete your gas installation by connecting the incoming gas line to the appliance regula-

tor. Secure all joints tightly with wrench but do not overtighten. If a exible gas line is used,

take care not to kink the connector.

WARNING: All gas piping

and connections must be tested for leaks after the installation is

completed. After ensuring that

the manual shutoff gas valve is

open, apply a soap and water

solution to all connections and

joints. If bubbles appear, leaks can be detected and corrected.

DO NOT USE OPEN FLAME FOR

LEAK TESTING AND DO NOT

OPERATE ANY APPLIANCE IF

A LEAK IS DETECTED.

GAS SUPPLY TESTING

Note: This section is intended as a guide for

qualied technicians installing gas to this vent-free rebox.

CAUTION: Do not connect

vent-free heater before pressure testing gas piping. Damage to

gas valve may result and an un-

safe condition may be caused.

The appliance and its’ individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).

The appliance must be isolated from the gas supply piping system by closing manual shutoff valve during any pressure testing of the gas

supply piping system at test pressures equal

to or less than 1/2 psig (3.5 kPa).

HARD-WIRING FIREBOX

Model UVC-ST only can be hard-wired to the duplex outlet located inside the rebox bottom if desired. This allows the blower accessory to

be plugged into the duplex outlet.

NOTICE: A qualied electrician

must connect electrical wiring to

duplex outlet for built-in installation. Follow all local codes. In

absence of local codes follow The National Electric Code ANS/

NFPA 70.

ELECTRICAL INSTALLATION

A model blower system assembly is available for use with the UVC-ST only vent-free rebox as an optional accessory. This blower

is designed to be installed on either side of

the UVC-ST only rebox, when provisions

for a 120 VAC supply connection are made

at either end of the cabinet. Use of a blower

system other than those manufactured by FMI

PRODUCTS, LLC voids the warranty. Electrical connections are made within the

receptacle with wires that are routed through

the bushing provided (see Figure 15). The

receptacle may be relocated to either side, when necessary. However, the cover plate

must be replaced over the unused access

point. Be certain to properly ground the ventfree rebox using the green grounding wire

(see Figure 17 on page 14).

INSTALLATION

Continued

Note: A 120V supply connection to the leads to the receptacle must be provided for use

with the optional blower kit whether installed during or after initial rebox installation. You

may not be able to install a supply connection

after the nal installation is completed. Refer to Optional Blower Assembly Installation for specics.

OPTIONAL BLOWER ASSEMBLY INSTALLATION

Proper installation of the blower system is required to insure that the maximum discharge

of air can be delivered through the louvers on

each side of the replace.

Note: You may perform this installation from

either side of the replace within either room. The lower door panels are removable from both sides of the rebox for better access.

1. Remove blower assembly from packaging and inspect fan and wiring for damage. If any wiring is loose or damaged, return

assembly for exchange to your dealer or distributor.

2. Remove bottom louver by pulling both spring latches (located in each end of

louver) toward center of appliance at the

same time until disengaged from locating

holes in rebox (see Figure 16).

3. Locate 2 strips of hook and loop mounting

strips on one side of base of lower compartment. Align mounting strips on blower with mounting strips on base of rebox.

4. Install blower housing with exhaust outlet ports directed upwards along inner side wall of lower compartment. The blower outlets must be installed ush to the outer

cabinet for air to ow properly.

5. Apply gentle force between hook and loop mounting strips to seat blower.

6. Remove control knob and lock nut from

blower speed control shaft.

7. Place speed control shaft through 3/8"

hole provided in right side of lower door

panel removed in step 2.

8. While supporting speed control housing, secure shaft in panel hole with lock nut.

Place control knob on shaft.

9. Plug blower power cord into receptacle located in lower rebox compartment.

Check to make sure there are no foreign

objects in blower wheel.

WARNING: Never touch blow-

er wheel while in operation.

10. Turn blower on and check for proper

operation.

11. Turn blower off before continuing.

12. Replace lower door panel by inserting tabs

on bottom of panel into locating slots on

rebox. Push door panel into an upright position and secure with screws removed

in step 2.

OPERATING GUIDELINES AND MAINTENANCE

INSTRUCTIONS

When lit for the rst time, a vent-free log heater will emit a slight odor for about an hour or two. This is a normal occurrence which is due to the “curing” of the logs and the “burn-in”

of internal paints and lubricants used in the manufacturing process.

Keep control compartments, logs, burners

and areas surrounding the logs clean by

vacuuming or brushing at least twice a year.

Temporary removal of the log set may ease the cleaning of the burner and pilot assembly.

In cleaning, take care not to alter the settings

on the pilot assembly. See the operating

instructions supplied with your vent-free log

heater for additional cleaning instructions.

WARNING: Logs can be very

hot! Allow logs to cool before

handling.

IMPORTANT: Turn off the gas supply at the external shutoff valve before servicing appliance. Any safety screen or guard removed for servicing must be replaced prior to operating the appliance.

Installation and repair should be done by a

qualied person. The appliance should be

inspected before use and at least annually by

a professional service person. More frequent cleaning may be required due to excessive lint from carpeting, pet hair, etc. It is imperative that the control compartments, burners and circulating air passageways of the appliance

be kept clean.

WARNING: Children and adults should be alerted to the hazards of high surface temperatures and to stay away to avoid

burns or clothing ignition. Young

children should be carefully

supervised when they are in the same room as the appliance.

For lighting and operating this vent -free rebox, please refer to the vent-free gas logs

manufacturer’s instruction manual.
