FRESH AIR FOR COMBUSTION AND VENTILATION

WARNING: This heater shall not be inst alled in a

confined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air. Read the following instructions to insure proper fresh air for this and other fuel-burning appliances in your home.

SAFETY DEVICE

This heater has a pilot with an Oxygen Depletion Sensor (ODS) safety shut off system. The ODS/pilot shuts off the heater if there is not enough fresh air.

IGNITION SYSTEM

PIEZO: BF10LP/ IR10LP – The heater is equipped with a

piezo manual ignitor. This system requires no matches, batteries, or other source to light heater.

Electronic: BF20LPT/BF30LPT/IR20LPT/IR30LPT – The heater is equipped with an electronic manual ignitor. This system requires no matches, or other source to light heater, but does require one AA battery to operate ignitor (AA Battery included).

To install or replace battery unscrew the ignitor cap (red button), insert battery and replace cap.

(AA Battery included)

THERMOSTATIC CONTROL ON THERMOSTAT MODELS

(BF20LPT, BF30LPT, IR20LPT and IR30LPT)

These heaters have a control valve with a thermostat sensing bulb. This results in the greatest heater comfort and may result in lower bills.

These heaters also include an electrical blower. The blower switch has three positions: MANUAL, OFF and AUTO. In AUTO, the blower will turn on and off as the heater cycles on and off. In MANUAL, the blower will run continuously . To turn blower off, use the OFF position.

LOCAL CODES

Install and use heater with care. Installation must conform to local codes or in the ab-

sences of local codes, use the latest edition of National Fuel Gas Code ANSI Z223.1/NFP A 54.

ESTABLISHING ADEQUATE VENTILA TION

The following are excerpts from National Fuel Gas Code, NFP A 54/ ANSI Z223.1, Section 5.3, Air for Combustion and Ventilation. All sp aces in homes fall

into one of the three following ventilation classifications:

1. Unusually Tight Construction

2. Unconfined Sp ace

3. Confined Space

This heater must not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air. The information on pages 3 through 5 will help you classify your space and provide adequate ventilation.

Unusually Tight Construction

If your home meets all of the three following criteria you must provide additional fresh air. See V entilation Air from Outdoors, page 5.

Unusually tight construction is defined as construction where:

a. Walls and ceilings exposed to the outside atmo-

sphere have a continuous water vapor retarder with a rating of one perm (6 x 10

-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 windows and door frames, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and at other openings.

If you home does not meet all of the three criteria above, see Determining the T ype of Heater Location Space, page 4.

Confined Space and Unconfined Space

The National Fuel Gas Code, NFP A 54/ ANSI Z223.1

defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m per kW) of the aggregate input rating of all appliances

Installation instructions and Owner’s Manual

installed in that space, and an unconfined 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 unconfined space.

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

DETERMINING THE TYPE OF HEA TER LOCATION SP ACE:

Use this method to determine if you have a confined or unconfined space.

Note: the space includes the room in which you install heater plus any adjoining rooms with doorless passageways or ventilation grilles between the rooms.

1. Find the volume of the space by multiplying room length x width x height.

Example: Space size 18f t (length) x 18ft. (width) x 8ft.

(height) = 2592

If additional ventilation to adjoining room is supplied with grilles or openings, add the volume of these rooms to the total volume of the space.

2. Divide the space volume by 50 cubic feet to determine the maximum Btu/hr the space can support.

Example: 2592 cu.ft. (volume of space) / 50 cu.ft. = 51.8

or 51,800 (maximum Btu/hr the space can support)

The space in the above example is a confined space because the actual Btu/hr used is more than the maximum Btu/hr the space can support.

Y ou must provide additional fresh air . Your options are as follows:

A. Rework worksheet, and the space of an adjoining

room. If the extra space provides an unconfined space, remove door to adjoining room or add ventilation grilles between the rooms. See Ventilation Air From Inside Building (Fig. 2)

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

From Outdoors (Fig. 3).

C.Install a lower Btu/hr heater if lower Btu/hr size makes

room unconfined.

If 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.

VENTILATION AIR Ventilation from Inside Building

This fresh air would come from an adjoining unconfined space. When ventilation 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 & 2 of fig. 2). Y ou can also remove door into adjoining room (see option3, fig 2). Follow the National Fuel Gas Code NFP A 54/ ANSI Z223.1, Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts.

WARNING: If the area in which the heater may be

operated is smaller than defined as an unconfined space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by the methods described in the National Fuel Gas Code, NFP A 54/ ANSI Z223.1, Section 5.3 or applicable local codes.

3. Add the Btu/hr of all the fuel-burning appliances in the space such as, V ent–free heater, Gas water heater , Gas furnace, Vented gas heater , Gas fireplace logs, and Other gas appliances*

*Do not include direct-vent gas appliances. Directvent draws combustion air from the outdoors and vents to the outdoors.

Example: Gas water heater 40,000 Btu/hr Vent Free Heater + 20,000 Btu/hr T otal =60,000 Btu/hr

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

Example:51,800 Btu/hr (maximum Btu/hr the space

can support)

60,000 Btu/hr (Actual amount of Btu/hr used)

Ventilation Grilles into Adjoining Room Option 1

WARNING: Rework worksheet, adding the sp ace of

the adjoining unconfined space. The combined space must have enough fresh air to supply all appliances in both spaces.

Ventilation from Outdoors

If necessary , provide extra fresh air by using ventilation grilles or ducts. Connect these items directly to the outdoors or spaces open to the outdoors. These include attics* and crawl spaces. Follow the National Fuel Gas Code NFP A 54/ ANSI Z223.1, Section 5.3, Air for Combustion and Ventilation for required size of ventilation grilles or ducts.

*IMPORTANT: Do not provide openings for inlet or outlet into attic. If attic has a thermostat-controlled power vent, heated air entering the attic will activate the power vent.

IMPORTANT: Vent-free heaters add moisture to the air. Although this is beneficial, installing heater in rooms without enough ventilation air may cause mildew to form from too much moisture. See Fresh Air for Combustion and Ventilation, p ages 3 through

CONNECTING TO GAS SUPPLY

WARNING: A qualified service person must connect

heater to gas supply . Follow all local codes.

Installation instructions and Owner’s Manual

WARNING: This appliance requires a 3/8” NPT

(National Pipe Thread) inlet connection to the pressure regulator. Use of floor mounting feet will require you to use a 3/8 NPT street elbow to make gas connection.

CAUTION: Never connect heater directly to the Propane supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and Propane/LP supply .

The installer must supply an external regulator . The external regulator will reduce the incoming gas pressure to between 1 1 and 14 inches of water. If you do not reduce incoming gas pressure heater regulator damage could occur. Inst all external regulator with the vent pointing down as shown in Figure 12. 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 large enough diameter to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.

Installation must include an equipment shutoff valve, union and plugged 1/8” NPT tap. Locate NPT tap within reach of test gauge hookup. NPT tap must be upstream from heater (see figure 12).
