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 ﬂ ames and glowing ceramic logs/coals. This heater is designed for vent-free op er a tion with ﬂ ue damper closed. It has been tested and approved to ANSI Z21.11.2 stan dard for unvented heaters. State and local codes in some areas pro hib it the use of ventfree heaters. This heater may also be op er at ed as a vented decorative (ANSI Z21.60) product by opening the ﬂ ue damper (Non-Thermostat Mod els Only).

SAFETY DEVICE

This heater has a pilot with an Oxygen Depletion Sensing (ODS) safety shutoff sys tem. The ODS/pilot is a re quired fea ture for ventfree room heat ers. 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 sourc es to light heater.

AIR FOR COMBUSTION AND VENTILATION

WARNING: This heater shall not be installed in a conﬁ ned space or unusually tight con struc tion un less pro vi sions are pro vid ed for ad e quate com bus tion and ven ti la tion air. Read the fol low ing in struc tions to in sure prop er fresh air for this and other fuel-burning ap pli anc es in your home.

Today’s homes are built more energy ef ﬁ cient than ever. New ma te ri als, increased in su la tion, and new construction methods help reduce heat loss in homes. Home own ers 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 pos si ble.

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 com bus tion and ven ti la tion.

Exhaust fans, ﬁ replaces, clothes dryers, and fuel burning appliances draw air from the house to operate. You must provide ad e quate fresh air for these ap pli anc es. 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, Sec tion 5.3, Air for Combustion and Ven ti la tion.

All spaces in homes fall into one of the three following ventilation classiﬁ cations:

1. Unusually Tight Construction

2. Unconﬁ ned Space

3. Conﬁ ned Space

The information on pages 4 through 6 will help you classify your space and provide ad e quate ven ti la tion.

Unusually Tight Construction

The air that leaks around doors and win dows may provide enough fresh air for combustion and ventilation. However, in buildings of unusually tight construction, you must provide additional fresh air.

AIR FOR COMBUSTION AND VENTILATION

Providing Adequate Ventilation (Cont.)

Determining Fresh-Air Flow for Heater Location

AIR FOR COMBUSTION AND VENTILATION

Continued

Unusually tight construction is de ﬁ ned as construction where:

a. walls and ceilings exposed to the outside at mo sphere

have a con tin u ous water vapor retarder with a rating of one perm (6 x 10 open ings gasketed or sealed and

b. weather stripping has been add ed on openable win-

dows and doors and

c. caulking or sealants are applied to areas such as

joints around window and door frames, be tween sole plates and ﬂ oors, be tween wall-ceiling joints, be tween wall panels, at pen e tra tions for plumb ing, electrical, and gas lines, and at other openings.

If your home meets all of the three criteria above, you

must pro vide ad di tion al fresh air. See Ventilation Air From Outdoors, page 6.

If your home does not meet all of the three criteria above, proceed to De ter min ing Fresh-Air Flow For Heater Lo- ca tion, below.

Conﬁ ned and Unconﬁ ned Space

The National Fuel Gas Code, ANSI Z223.1/NFPA 54 deﬁ nes a con ﬁ 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 gre gate input rating of all ap pli anc es in stalled in that space and an un con ﬁ ned space as a space whose vol ume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the ag gre gate input rating of all appliances in stalled in that space. Rooms com mu ni cat ing di rect ly with the space in which the ap pli anc es are in stalled*, through openings not fur nished with doors, are con sid ered a part of the unconﬁ ned space.

* Adjoining rooms are communicating only if there are doorless passageways or ven ti la tion grills between them.

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

Determining if You Have a Conﬁ ned or Unconﬁ ned Space

Use this work sheet to determine if you have a conﬁ ned or un con ﬁ 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. (vol ume of space)

Example: Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceil ing

height) = 2560 cu. ft. (vol ume of space)

-11

kg per pa-sec-m2) or less with

If additional ventilation to adjoining room is supplied with grills or open-

ings, add the volume of these rooms to the total vol ume 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 sup port)

Example: 2560 cu. ft. (volume of space) x 20 = 51,200 (max i mum

Btu/Hr the space can sup port)

3. Add the Btu/Hr of all fuel burning ap pli anc es in the space.

Vent-free heater _____________ Btu/Hr

Gas wa ter heater* _____________ Btu/Hr

Gas fur nace _____________ Btu/Hr

Vented gas heater _____________ Btu/Hr

Gas ﬁ re place logs _____________ Btu/Hr

Other gas appliances* + _____________ Btu/Hr

Total = _____________ Btu/Hr

* Do not include direct-vent gas ap pli anc es. Direct-vent draws com-

bus tion air from the outdoors and vents to the outdoors.

Example:

Gas water heater _____________ Btu/Hr

Vent-free heater + _____________ Btu/Hr

Total = _____________ Btu/Hr

4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.

____________________Btu/Hr (maximum the space can sup port)

____________________Btu/Hr (actual amount of Btu/Hr used)

Example: 51,200 Btu/Hr (max i mum the space can support)

73,000 Btu/Hr (actual amount of Btu/Hr used)

The space in the above example is a con ﬁ 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 op tions are as follows:

A. Rework worksheet, adding the space of an adjoining room. If the ex tra

space provides an unconﬁ ned space, remove door to ad join ing room or add ven ti la tion grills between rooms. See Ven ti la tion Air From Inside Building, page 6.

B. Vent room directly to the outdoors. See Ventilation Air From Out doors,

page 6.

C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room un con -

ﬁ ned.

If the actual Btu/Hr used is less than the maximum Btu/Hr the space can sup port, the space is an unconﬁ ned space. You will need no additional fresh air ven ti la tion.

40,000

33,000

73,000

WARNING: If the area in which the heater may be operated is smaller than that deﬁ ned as an un con ﬁ ned space or if the building is of unusually tight construction, provide ad e quate com bus tion and ven ti la tion air by one of the methods described in the National Fuel Gas Code, ANSI Z223.1/NFPA 54 Sec tion 5.3 or applicable local codes.

This fresh air would come from an adjoining unconﬁ ned space. When ventilating to an adjoining unconﬁ ned space, you must pro vide two permanent open ings: one within 12" of the ceiling and one within 12" of the ﬂ oor on the wall con nect ing the two spaces (see options 1 and 2, Figure 2). You can also remove door into adjoining room (see op tion 3, Figure 2). 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.

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or ducts. You must provide two per ma nent open ings: one within 12" of the ceiling and one within 12" of the ﬂ oor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. Follow the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation for required size of ven ti la tion grills or ducts.

IMPORTANT: Do not provide openings for inlet or outlet air into attic if attic has a ther mo stat-controlled power vent. Heated air entering the attic will activate the power vent.

INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED OPERATION

Note: When used as a vented decorative, ap pli ance must be installed only in a solid-fuel burning ﬁ replace with a working ﬂ ue and constructed of noncombustible material.

If your heater is a non-thermostatically-controlled mod el, you may use this heater as a vented prod uct. There are three reasons for op er at ing your heater in the vented mode.

1. The ﬁ replace does not meet the clear ance to com bus ti bles re quire ments 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 chim ney ﬂ ue damper. You must install the damper clamp accessory (to order, see Accessories, page 27). This will insure vented op er a tion (see Figure 10). The damper clamp will keep damper open. Installation instructions are included with clamp accessory.

See chart below for minimum permanent ﬂ ue opening you must provide. Attach damp er clamp so the minimum permanent ﬂ ue opening will be main tained at all times.

INSTALLING HEATER ASSEMBLY

WARNING: If installing in a sunken ﬁ re place, special care is needed. You must raise the ﬁ re place ﬂ oor to allow access to heat er control panel. This will in sure ad e quate air ﬂ ow and guard against soot ing. Raise ﬁ replace ﬂ oor with noncom bus ti ble ma te ri al. Make sure material is secure.

CAUTION: Do not pick up heat er as sem bly by logs. This could damage unit. Only handle assembly by grates.

IMPORTANT: Make sure the heater burn ers are level. If heater is not level, heater will not work properly.

Installation Items Needed

• control cover kit (provided with heater)

• approved ﬂ exible gas hose and ﬁ ttings (pro vid ed with heater) (if al lowed by lo cal codes)

• sealant (resistant to propane/LP gas, not pro vid ed)

Note: Install optional GHRCTA Receiver and Hand-Held Remote Control Kit (see Ac ces so ries, page 27) before in stall ing gas log heater (Remote-Ready Models Only). See installation in struc tions in clud ed with the kit.

1. Apply pipe joint sealant lightly to male threads of gas ﬁ tting

(not provided). Connect ap proved ﬂ exible gas hose to inlet side of gas con trol (see Figure 11).

2. Position heater assembly in ﬁ re place.

3. Connect to gas supply. See Con nect ing To Gas Supply, (see

INSTALLATION

Continued

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

WARNING: A qualiﬁ ed ser vice per son must con nect heater to gas sup ply. Follow all local codes.

CAUTION: Never connect propane/LP ﬁ replace directly to the propane/LP supply. This heater re quires an external regulator (not supplied). Install the external regu la tor be tween the heater and propane/LP supply.

WARNING: Never connect natural gas ﬁ replace to pri vate (non-utility) gas wells. This gas is com mon ly 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

• approved ﬂ exible gas line with gas con nec tor (if allowed by lo cal codes) (provided)

* A CSA design-certiﬁ ed equipment shutoff valve with 1/8" NPT tap is an ac cept able alternative to test gauge con nec tion. Pur chase the optional CSA design-certiﬁ ed equipment shutoff valve from your dealer. See Accessories, page 27.

For propane/LP units, the installer must supply an external reg u la tor. The external reg u la tor will reduce incoming gas pressure. You must reduce in com ing gas pressure to between 11 and 14 inches of water. If you do not reduce in com ing gas pressure, heater regulator damage could occur. Install external reg u la tor with the vent point ing down as shown in Figure 12. Pointing the vent down protects it from freezing rain or sleet.

Installing Heater Assembly (Cont.)

INSTALLATION

Connecting to Gas Supply

CONNECTING TO GAS SUPPLY

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 up stream from heater (see Figure 13 page 12, depending on your model).

IMPORTANT: Install equipment shutoff valve in an ac ces si ble lo ca tion. The equip ment shutoff valve is for turning on or shut ting off the gas to the appliance.

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 seal ant that is resistant

to liquid pe tro leum (LP) gas.

We recommend that you install a sediment trap in sup ply line as shown in Figure 13 page 12, depending on your model. Locate sed i ment trap where it is with in reach for cleaning. Install in piping system between fuel supply and heater. Locate sed i ment trap where trapped mat ter is not likely to freeze. A sediment trap traps mois ture and con tam i nants. This keeps them from going into heater controls. If sediment trap is not in stalled or is installed wrong, heater may not run properly.

CAUTION: Avoid damage to gas control. Hold gas control with wrench when connecting it to gas piping and/or ﬁ ttings.

External Regulator Propane/LP Supply Tank

Vent Pointing Down

CAUTION: Use only new, black iron or steel pipe. In ter nal ly-tinned copper tubing may be used in cer tain areas. Check your local codes. Use pipe of 1/2" di am e ter or greater to allow prop er gas vol ume to heater. If pipe is too small, undue loss of volume will occur.

CLEANING AND MAINTENANCE

Cleaning Burner Injector Holder and Pilot Air Inlet Hole

CLEANING AND MAINTENANCE

if com pressed air is not available.

WARNING: Turn off heater and let cool before

cleaning.

CAUTION: You must keep control areas, burners, and cir cu lat ing air pas sage ways of heat er clean. In spect these areas of heater before each use. Have heater inspected yearly by a qual i ﬁ ed service person. Heater may need more fre quent cleaning due to ex ces sive lint from car pet ing, pet hair, bedding ma te ri al, etc.

CLEANING BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE

The primary air inlet opening allow the proper amount of air to mix with the gas. This provides a clean burning ﬂ ame. Keep these holes clear of dust, dirt, lint, and pet hair. Clean these air inlet opening prior to each heating season. Blocked air opening will cre ate soot. We rec om mend that you clean the unit every three months during operation and have heater inspected yearly by a qual i ﬁ ed service person.

We also recommend that you keep the burn er tube and pilot assembly clean and free of dust and dirt. To clean these parts we rec om mend using compressed air no greater than 30 PSI. Your local computer store, hard ware store, or home center may carry com pressed 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 di rec tions on the can. If you don't follow di rec tions on the can, you could damage the pilot as sem bly.

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 opening 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 burn er tube again. Remove any large particles of dust, dirt, lint, or pet hair with a soft cloth or vacuum clean er nozzle.

5. Blow air into the primary air opening on the injector hold er.

6. In case any large clumps of dust have now been pushed into the burner re peat steps 3 and 4.

Clean the pilot assembly also. A yellow tip on the pilot ﬂ ame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about two inches from where the pilot ﬂ 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
