PRODUCT FEATURES

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 ames and glowing coals. This

heater is designed for vent-free operation

with ue 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 ue damper.

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 appliances need fresh air for proper combustion and ventilation.

Exhaust fans, replaces, 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, Air for Combustion and Ventilation.

SAFETY DEVICE

This heater 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 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.

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 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 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 Heater Location, page 7.

Conned and Unconned Space

The National Fuel Gas Code, ANSI 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 per hour (4.8 m3 per kw) of the ag-

gregate 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 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 unconned 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 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 20 ft. (length) x 16 ft.

(width) x 8 ft. (ceiling height) = 2560 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: 2560 cu. ft. (volume of space) x 20

= 51,200 (maximum Btu/Hr the space can

support)

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

Vent-free replace __________ Btu/Hr 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 Vent-free replace + ________ Btu/Hr

Total _________ = Btu/

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) ______ Example: 51,200 Btu/Hr (maximum the

73,000 Btu/Hr (actual amount of

2. State or local codes do not permit ventfree operation.

3. You prefer vented operation.

If reasons number 1 or 2 apply to you, you must permanently open chimney ue damper. You must install the damper clamp accessory (to order, see Accessories, page

30). This will insure vented operation (see Fig-

ure 10). The damper clamp will keep damper

open. Installation instructions are included

with clamp accessory. See chart for minimum permanent ue open-

ing you must provide. Attach damper clamp so

the minimum permanent ue opening will be

maintained at all times.

Note: When used as a vented heater, appliance must be installed only in a solid-fuel burning replace with a working ue and constructed of noncombustible material.

For Massachusetts Residents Only: Installation of this vented gas log set in the Com-

monwealth of Massachusetts requires the damper be permanently removed or welded

in the fully open position.

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 replace does not meet the clearance

to combustibles requirements for vent-free operation.

adjust controls. Moving heater may cause a gas leak or log misplacement.

WARNING: If installing in a sunken replace, special care is needed. You must raise the replace oor to allow access to heater control panel. This will insure adequate air ow and guard against sooting and controls being damaged. Raise replace oor with noncombustible material. Make sure material is secure.

CAUTION: Do not pick up heater base assembly by burners. This could damage heater. Only handle base assembly by grates.

IMPORTANT: Make sure the heater burners

are level. If heater is not level, heater will not work properly.

Installation Items Needed

• hardware package (provided with heater)

• approved exible gas hose and ttings (not provided) (if allowed by local codes)

• sealant (resistant to propane/LP gas, not

provided)

• electric drill with 3/16" drill bit (metal or

masonry as applicable)

• athead screwdriver

• pipe wrench

1. Connect approved exible gas hose to gas

control tting in heater (see Figure 11).

IMPORTANT: Hold gas tting with wrench

when connecting exible gas hose.

2. Locate two masonry screws in hardware

package.

3. Place heater base in replace.

4. Place logs in their proper position on heater base (see Installing Logs, page 17).

5. Center heater base and logs front-to-back

and side-to-side in replace.

6. Carefully remove logs without moving

heater base.

7. Mark screw locations through one hole on

each side of the mounting bracket (see

Figure 12, page 14). If installing in a brickbottom replace, mark screw locations in

mortar joint of bricks.

8. Remove heater base from replace. If installing optional control accessories, do so at this time. Follow all directions provided with accessory.

CONNECTING TO GAS SUPPLY

WARNING: This appliance requires a 3/8" NPT (National Pipe Thread) inlet connection to the pressure regulator.

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

CAUTION: Never connect

propane/LP replace 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 replace to private (non-utility) gas wells. This gas is commonly known as wellhead gas.

Continued

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 equipment shutoff valve with 1/8" NPT

tap is an acceptable alternative to test gauge connection. Purchase the optional equipment shutoff valve from your dealer.

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" 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

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 heater. If pipe is too small, undue loss of volume will occur.

INSTALLATION

Continued

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).

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 requirements for locating equipment shutoff

valve to replaces.

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. 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 gas control. Hold gas tting with wrench when connecting it to gas piping and/or ttings.

WARNING: Failure to keep

Burner Tube

the primary air opening(s) of the burner(s) clean may result in sooting and property damage.

BURNER ORIFICE 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 ame. Keep these holes clear of dust, dirt, lint and pet hair. Clean these air in-

let 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 qualied 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. 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 dam-

age 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 orice holder for dust and dirt

(see Figures 26 and 27).

3. Blow air through the ports/slots and holes

in the burner.

4. Check the orice 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 orice 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 ame indicates dust and dirt in

the pilot assembly. There is a small pilot air

inlet hole about two inches from where the pilot ame 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.
