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 coals. This heater is designed for vent-free operation with ﬂ ue damper closed. It has been tested and approved to the ANSI Z21.11.2 standard for unvented heaters. State and local codes in some areas prohibit the use of vent-free heaters. This appliance may also be operated as a vented decorative (ANSI Z21.60) product by opening the ﬂ 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 ensure proper fresh air for this and other fuel-burning appliances in your home.

Today’s homes are built more energy efﬁ cient than ever. New materials, increased insulation and new construction methods help reduce heat loss in homes. Homeowners apply weather strip and caulk around windows and doors to keep the cold air out and the warm air in. During heating months, homeowners 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, some ﬁ replaces, clothes dryers and some fuel-burning appliances draw air from the house to operate. You must provide adequate fresh air for these appliances. That will ensure 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.

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 5 through 7 will help you classify your

space and provide adequate 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 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 Igniter. This system requires no matches, batteries or other sources to light heater.

Unusually tight construction is deﬁ ned as construction where: a. walls and ceilings exposed to the outside atmosphere have a

continuous water vapor retarder with a rating of one perm (6 x

-11

kg per pa-sec-m2) or 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 ﬂ 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 three criteria above, you must provide additional fresh air. See Ventilation Air From Outdoors, page 7.

If your home does not meet all three criteria above, proceed to De- termining Fresh-Air Flow For Heater Location, page 6.

Conﬁ ned and Unconﬁ ned Space

The National Fuel Gas Code, ANSI Z223.1/NFPA54 allows two methods for determining whether the space in which the heater is being installed is conﬁ ned or unconﬁ ned space. The standard method deﬁ nes a conﬁ ned space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m input rating of all appliances installed in that space and an unconﬁ 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 unconﬁ ned space.

Where the air inﬁ ltration rate of a structure is known, the Known Air Inﬁ ltration Rate Method may be used. Follow The National Fuel Gas Code, ANSI Z223.1/NFPA 54 to use this method to determine if the space is conﬁ ned or unconﬁ ned.

per kw) of the aggregate

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.

ComfortFlame.US.com900554-00 NC 5

* 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 Conﬁ ned or Unconﬁ ned Space Using the Standard Method

Use this work sheet to determine if you have a conﬁ ned or unconﬁ 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 = (Maximum 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 ﬁ replace ________Btu/Hr

Gas water heater* ________Btu/Hr

Gas furnace ________Btu/Hr

Vented gas heater ________Btu/Hr

Gas ﬁ 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.

The space in the above example is a conﬁ ned 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

extra space provides an unconﬁ ned space, remove door to adjoining room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 6.

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

Outdoors, page 7.

C. Install a lower Btu/Hr appliance, if lower Btu/Hr size makes room

unconﬁ ned.

If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconﬁ 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

Ventilation Air From Inside Building

This fresh air would come from an adjoining unconﬁ ned space. When ventilating to an adjoining unconﬁ ned space, you must provide two permanent openings: one within 12" of the ceiling and one within 12" of the ﬂ oor on the wall connecting the two spaces (see options

1 and 2, Figure 2). You can also remove door into adjoining room (see option 3, Figure 2). Follow the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation for required size

of ventilation grills or ducts.

Example: Gas water heater 40,000 Btu/Hr Vent-free ﬁ replace + 33,000 Btu/Hr Total = 73,000 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 support)

INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED OPERATION

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

For Massachusetts Residents Only: Installation of this vented gas log set in the Commonwealth 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 ﬁ replace does not meet the clearance to combustibles requirements 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 apply to you, you must permanently open chimney ﬂ ue damper. You must install the damper clamp accessory (to order, see Accessories, page 24). This will ensure 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 3/8" NPT (National Pipe Thread) inlet connection to the pressure regulator.

WARNING: A qualiﬁ ed service person must con-

nect appliance to gas supply. Follow all local codes.

CAUTION: Never connect propane/LP appliance 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.

INSTALLATION

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 al-

ternative 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.

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 appliances.

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 clean- ing. 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: 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.

CLEANING AND MAINTENANCE

INSPECTING BURNERS

Check pilot ﬂ ame pattern and burner ﬂ ame patterns often.

PILOT FLAME PATTERN

Figure 24 shows a correct pilot ﬂ ame pattern. Figure 25 shows an incorrect pilot ﬂ ame pattern. The incorrect pilot ﬂ ame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.

If pilot ﬂ ame pattern is incorrect, as shown in Figure 32

• turn heater off (see To Turn Off Gas to Appliance, page 16)

• see Troubleshooting, pages 20 and 21.

NOTE: The pilot ﬂ ame on natural gas units will have a slight curve, but ﬂ ame should be blue and have no yellow or orange color.

Pilot Burner

Figure 24 - Correct Pilot Flame Pattern (Your pilot may vary from pilot shown)

Thermocouple

WARNING: Turn off heater and let cool before

cleaning.

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 qualiﬁ ed 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 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 ﬂ ame. 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 qualiﬁ ed service person.

Pilot Burner

Figure 25 - Incorrect Pilot Flame Pattern (Your pilot may vary from pilots shown)

BURNER PRIMARY AIR HOLES

Air is drawn into the burner through the holes in the ﬁ tting at the burner entrance. These holes may become blocked with dust or lint. Periodically inspect these holes for any blockage and clean if needed. Blocked air holes will create soot.

MAIN BURNER

Periodically inspect all burner ﬂ ame holes with the heater running. All slotted burner ﬂ ame holes should be open with yellow ﬂ ame present. All round burner ﬂ ame holes should be open with a small blue ﬂ ame present. Some burner ﬂ ame holes may become blocked by debris or rust, with no ﬂ ame present. If so, turn off heater and let cool. Remove blockage. Blocked burner ﬂ ame holes will create soot.

Thermocouple

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 damage 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 oriﬁ ce holder for dust and dirt (see Figures 26 and 27).

ComfortFlame.US.com900554-00 NC 17

CLEANING AND MAINTENANCE

Thermopile

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

4. Check the oriﬁ 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 oriﬁ 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 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 if compressed air is not available.
