IGNITION SYSTEM

PIEZO: BF6NG/BF10NG / IR10NG – The heater is equipped with a piezo manual ignitor. This system requires no matches, batteries, or other source to light heater.

Electronic: BF20NGT/BF30NGT/IR20NGT/IR30NGT

–The heater is equipped with an electronic manual ig- nitor. This system requires no matches, or other source to light heater, but does require one AA battery to oper- ate ignitor.(AA Battery included).

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

(AA Battery included)

THERMOSTATIC CONTROL ON

THERMOSTAT MODELS

(BF20NGT, BF30NGT, IR20NGT and IR30NGT)

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. On 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/NFPA 54.

UNPACKING

1.Remove heater from carton.

2.Remove all protective packaging applied to heater for shipment.

3.Check heater for any shipping damage. If heater is damaged, promptly inform dealer where you bought heater.

FRESH AIR FOR COMBUSTION AND VENTILATION

WARNING: This heater shall not be installed in a confined space or unusually tight construction un- less provisions are provided for adequate combus- tion and ventilation air. Read the following instruc- tions to insure proper fresh air for this and other fuel-burning appliances in your home.­

ESTABLISHING ADEQUATE VENTILATION

The following are excerpts from National Fuel Gas Code, NFPA 54/ ANSI Z223.1, Section 5.3, Air for Com- bustion 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

This heater must not be installed in a confined space or unusually tight construction unless provisions are pro- vided 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 Ventilation 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 10-11kg per pa-sec-m2) or less with openings gasketed or sealed and

b.Whether stripping has been added on openable win- dows 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 penetra- tions for plumbing, electrical, and gas lines, and at other openings.

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

Confined Space and Unconfined Space

The National Fuel Gas Code, NFPA 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 m3 per kW) of the aggregate input rating of all appliances
