IMPORTANT SAFETY INFORMATION

INSTALLER: Please leave these instructions with the owner.

OWNER: Please retain these instructions for future reference.

IMPORTANT: Read these instructions carefully before installing or trying to operate this heater.

WARNING

WARNING: Any change to this heater or its controls can be dangerous. Improper installation or use of the heater can cause serious injury or death from fire, burns, explosion or carbon monoxide poisoning.

1.CARBONMONOXIDEPOISONING:Early signsof carbonmonoxide poisoningaresimilar totheflu with headaches, dizziness and/or nausea. If you have these signs, obtain fresh air immediately. Have the heater serviced as it may not be operating properly.

2.The installation must conform with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1.

3.The B2045N/B2045L vent-free gas heater system cannot be installed in a bedroom.

4.Do not install the heaters in a bathroom.

5.WARNING:Improperinstallation,adjustment,alteration,serviceormaintenancecancauseinjuryorproperty damage. Refer to this owner's manual. Installation and service must be performed by a qualified installer; service agency or the gas supplier.

6.To prevent malfunction and/or sooting, an unvented gas heater should be cleaned at least annually by a professional service person. More frequent cleaning may be required due to excessive lint from carpeting, etc. It is imperative that control compartments, burners and circulating air passageways be kept clean.

7.Correct placement of the ceramic fiber logs is necessary to avoid problems with sooting. Sooting can settle on surfacesoutsidetheheaterandcausediscoloration.Seetheappropriatesectionsofthismanualforinstructions.

8.WARNING: Do not allow fans to blow directly into the fireplace. Avoid any drafts that alter burner flame patterns. Donotplaceablowerinsideburnareaoffirebox.Ceilingfansmaycreatedraftsthatalterburnerflame patterns. Sooting and improper burning will occur.

9.This is an vent-free gas-fired heater. It uses air (oxygen) from the room in which it is installed. Provisions for adequate combustion and ventilation air must be provided. Refer to installation guidelines.

10.Children and adults should be alerted to the hazard of high surface temperature and should stay away to avoid burns or clothing ignition.

11.Young children should be carefully supervised when they are in the same room with the appliance.

IMPORTANT SAFETY INFORMATION

12.Do not place clothing or other flammable material near the appliance.

13.Keep appliance area clear and free from combustible materials, gasoline and other flammable vapors and liquids.

14.Any safety screen or guard removed for servicing, must be replaced prior to operating the heater.

15.This vent-free gas heater is intended to be smokeless. If logs appear to smoke, turn off the heater and call a qualified service person. Initial burn off may cause slight smoke and odor during the first four hours of operation.

16.Input ratings are shown in BTU per hour and are for elevations up to 2,000 feet. For elevations above 2,000 feet, input ratings should be reduced 4 percent for each 1,000 feet above sea level. Refer to the National Fuel Gas Code.

ITEMS REQUIRED FOR INSTALLATION

ITEMS REQUIRED FOR INSTALLATION

Ensure that the following items are available before proceeding with installation:

• External regulator (for propane/LPG only)

• Manual shutoff valve

• Piping which complies with local codes

• Sediment trap

• Pipe sealant approved for use with

• Pipe wrench

propane/LPG (resistant to sulfur compounds)

 

CODES

Adhere to all local codes or in their absence, the latest edition of THE NATIONAL FUEL GAS CODE ANSI Z223.1 or NFPA54 which can be obtained from:

American National Standards Institute, Inc.

 

National Fire Protection Association, Inc.

1430 Broadway

or

Batterymarch Park

New York, NY 10018

 

Quincy, MA 02269

Due to high temperatures, do not install the heater:

 

WARNING

 

 

• Where curtains, furniture, clothing or other flammable objects are less than 42" from the front of the heater.

• In high traffic areas.

• In windy or drafty areas. DONOTPLACECLOTHINGOROTHERFLAMMABLEMATERIALONORNEARTHE APPLIANCE.

ADEQUATE COMBUSTION AND VENTILATION AIR

This heater shall not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air.

Unusually tight construction is defined as construction where:

(a)Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of 1 perm (6 x 1011kg 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 floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and at other openings.

The National Fuel Gas Code defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 BTU per hour (4.8m3per kw) of the aggregate input rating of all appliances installed in that space and an unconfined space is defined as a space whose volume is not less than 50 cubic feet per 1,000 BTU per hour (4.8m3per 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.

INSTALLATION

The following formula can be used to determine the maximum heater rating per the definition of unconfined space:

BTU/HR = (L1+L2) Ft x (W) Ft x (H) Ft x 1000 50

Consider two connecting rooms with an open area between,

with the following dimensions:(See Fig. 2, Example)

 

 

L1=15-1/2 Ft., L2=12 Ft., W=12 ft., H=8Ft

 

H (8')

50

 

L2 (12')

 

=52800 BTU/HR

 

 

 

 

L1 (15-1/2')

W (12')

 

 

If there were a door between the two rooms the calculation

 

 

would be based only on the room with the heater.

 

BTU/HR=(15-1/2) x (12) x (8) x 1000

FIGURE 2.

=29760 BTU/HR

 

WARNING WARNING WARNING

When installing the appliance directly on carpeting, tile or other combustible material, other than wood flooring, the appliance must be installed on a metal or wood panel extending the full width and depth of the appliance.

If the area in which the heater may be operated is smaller than that defined as an unconfined space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code, ANSI Z223.1, Section 5.3, or applicable local codes.

Ensure the minimum clearances shown in FIGURE 3 are maintained for accessibility for purposes of servicing and proper operation. Left and right clearances are determined when facing the front of the heater.

GAS CONNECTION

NOTICE

CAUTION

A qualified gas appliance installer must connect the fireplace to the gas supply. Consult all local codes.

Usenewblackironorsteelpipe only.Internallytinnedcoppertubingcanbeusedinsome areas when permitted by local codes. Only use pipe of 1/2" or greater diameter to allow full gas volume to heater. Excessive pressure loss will occur if the pipe is too small.

A manual shutoff valve, union and plugged 1/8" NPT pressure tapping point must be installed upstream of the heater (FIGURE 4).
