Air for Combustion and Ventilation

WARNING: This heater shall notbeinstalledinaroomorspace unless the required volume of indoorcombustionairisprovided by the method described in the

National Fuel Gas Code, ANSI Z223.1/NFPA54, the International Fuel Gas Code,or applicable local codes. Read the following instructionstoinsureproperfresh airforthisandotherfuel-burning appliances in your home.

Today’s 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 efficient, your home needs to breathe. Fresh air must enter your home. All fuel-burningappliances need fresh air for proper combustion and ventilation.

Exhaust fans, fireplaces, clothes dryers, and fuelburningappliancesdrawairfromthehouse to operate. You must provide adequate fresh air for these appliances.This will insure proper venting of vented fuel-burningappliances.

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 classifications:

1.Unusually Tight Construction

2.Unconfined Space

3.Confined 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 defined as construction where:

a.walls and ceilings exposed to the outside atmosphere have a continuous watervaporretarderwitharatingofone perm (6x10-11 kg perpa-sec-m2)or less with openings gasketed or sealedand

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-ceilingjoints, 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,youmustprovideadditionalfreshair.

See Ventilation Air From Outdoors, page 8.

If your home does not meet all of the three criteriaabove,proceedtoDetermining FreshAir Flow For Heater Location, page 7.

Confined 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/hr (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space and an unconfined space as a space whosevolumeisnotlessthan50cubicfeetper 1,000 Btu/hr (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space.Roomscommunicatingdirectlywiththe space in which the appliances are installed*, throughopeningsnotfurnishedwithdoors,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-AIRFLOW 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 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 =__________ c u . 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.

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: 51,200 Btu/Hr (maximum the space can support)

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

The space in this 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 additional fresh air. Your options are as follows:

A.Rework worksheet, adding the space of an adjoining 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

Ventilation Air From Outdoors,page 8.

C.Install a lower Btu/Hr heater, 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, the space is an unconfined space.You will need no additional fresh air ventilation.

WARNING:Iftheareainwhich theheatermaybeoperateddoes notmeettherequiredvolumefor indoorcombustionair,combustion and ventilation air shall be provided by one of the methods described in theNational Fuel GasCode,ANSIZ223.1/NFPA54, theInternational Fuel Gas Code, or applicable local codes.

VENTILATION AIR

Ventilation Air From Inside Building

This fresh air would come from an adjoining unconfined 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 2, page 8). 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.

ACCESSORY FOR VENTED

OPERATION

Note: When used as a vented heater, appliance must be installed only in a solid-fuelburning fireplace with a working flue 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 fireplace does not meet the clearance to combustibles requirements for ventfree operation

2.State or local codes do not permit ventfree operation

3.You prefer vented operation

If reasons number 1 or 2 above apply to you, you must permanently open chimney flue damper. You must install the damper clamp accessory (to order, see Accessories, page 29). This will insure vented operation (see Figure 10, page 13). The damper clamp will keep damper open. Installation instructions are included with clamp accessory.

Installation Items Needed

Before installing heater, make sure you have the items listed below.

external regulator (for propane/LP units only, 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. See Accessories, page 29.

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 withtheventpointingdownasshowninFigure 13. Pointing the vent down protects it from freezing rain or sleet.

WARNING: A qualified servicepersonmustconnectheater to gas supply. Follow all local codes.
