INSTALLER

Please leave these instructions with the appliance.

OWNER

Please retain these instructions for future reference

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 re, burns,

explosion or carbon monoxide poisoning.

• Do not allow fans to blow directly into the replace. Avoid any drafts that alter burner ame patterns.

• Do not use a blower insert, heat exchanger insert or other accessory, not approved for

use with this heater where applicable.

1. Due to high temperatures, the rebox should be

located out of trafc and away from furniture and

draperies.

2. Children and adults should be alerted to the hazard

of high surface temperature and should stay away

to avoid burns or clothing ignition.

3. Young children should be carefully supervised when

they are in the same room with the rebox.

4. Do not place clothing or other ammable material

near the replace when the rebox is in use.

5. Any safety screen or guard removed for servicing,

must be replaced prior to operating a heater within

the rebox.

6. Installation and repair should be done by a qualied

service person.

7. To prevent malfunction and/or sooting, an unvented

gas heater/rebox should be cleaned at least annu-

ally by a professional service person. More frequent

cleaning may be required due to excessive lint from

carpeting, etc. It is imperative that control compart-

ments, burners and circulating air passageways be

kept clean.

8. CARBON MONOXIDE POISONING: Early signs of

carbon monoxide poisoning are similar to the u 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.

9. The installation must conform with local codes or, in

the absence of local codes, with the National Fuel Gas

Code, ANSI Z223.l/NFPA54.

10. This unit complies with ANSI Z21.91 ventless rebox

enclosures for gas-red unvented decorative room

heaters.

11. Do not install the unvented heater in a bathroom.

12. Do not install the unvented heater in a bedroom unless

the maximum input rating is equal to or less than

10,000 Btu/hr.

13. Correct installation of the ceramic ber logs, proper

location of the heater, and annual cleaning are neces-

sary to avoid potential problems with sooting. Sooting,

resulting from improper installation or operation, can

settle on surfaces outside the replace. See log place-

ment instructions for proper installation.

14. Avoid any drafts that alter burner ame patterns. Do not

allow fans to blow directly into replace. Do not place

a blower inside burn area of rebox. Ceiling fans may

create drafts that alter burner ame patterns. Sooting

and improper burning will occur.

15. CAUTION: Candles, incense, oil lamps, etc. produce

combustion byproducts including soot. Vent-free

appliances will not lter or clean soot produced by

these types of products. In addition, the smoke and/

or aromatics (scents) may be re-burnt in the vent-free

appliance which can produce odors. It is recommended

to minimize the use of candles, incense, etc. while the

vent-free appliance is in operation.

16. An unvented gas-red heater uses air (oxygen) from

the room in which it is installed. Provisions for adequate

combustion and ventilation air must be provided. See

installation guidelines.

17. Keep room area clear and free from combustible mate-

rials, gasoline and other ammable vapors and liquids.

18. Unvented gas heaters are a supplemental zone heater.

They are not intended to be a primary heating appli-

ance.

19. Unvented gas heaters emit moisture into the living

area. In most homes of average construction, this

does not pose a problem. In houses of extremely

tight construction, additional mechanical ventilation is

recommended.

20. During manufacturing, fabricating and shipping, various

components of this appliance are treated with certain

oils, lms or bonding agents. These chemicals are not

harmful but may produce annoying smoke and smells

as they are burned off during the initial operation of the

appliance; possibly causing headaches, or eye or lung

irritation. This is a normal and temporary occurrence.

2 Important Safety and Operating Information

6Monessen • BUF36/42 Installation and Operating Manual • 4600-900 • Rev E • 09/17

WARNING!

Do not attempt to burn solid wood fuels, vented

gas log sets, or any other combustible in this

unvented rebox. Also, do not install a vent-

free gas log set in this rebox if the minimum

clearance and height requirements of the log

set are too large for the rebox.

Continued from page 6

The initial break-in operation should last two to three

hours with the burner at the highest setting. Provide

maximum ventilation by opening windows or doors to

allow odors to dissipate. Any odors remaining after this

initial break-in period will be slight and will disappear

with continued use.

21. 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.

22. The appliance and its main gas valve must be discon-

nected from the gas supply piping system during any

pressure testing of that system at test pressures in

excess of 1/2 psig (3.5 kPa).

23. The appliance must be isolated from the gas supply

piping system by closing its equipment shutoff valve

during any pressure testing of the gas supply piping

system at test pressures equal to or less than 1/2 psig

(3.5 kPa).

24. Do not use this room heater if any part has been under

water. Immediately call a qualied service technician

to inspect the room heater and to replace any part of

the control system and any gas control which has been

under water.

25. Never burn solid fuels in a replace where a unvented

room heater is installed.

26. Always have a replace screen in place when the

appliance is in operation, and unless other provisions

for combustion air are provided, the screen shall have

an opening(s) for induction of combustion air.

27. Do not ll spaces around the rebox with insulation or

other materials. These spaces must be maintained to

prevent the rebox from coming in contact with com-

bustible materials.

Notice: Illustrations shown in this manual reect

“typical” installations with nominal dimensions and

are for design and framing reference only. Actual

installations may vary due to individual design

preferences. However, always maintain minimum

clearances to combustible materials and do not

violate any specic installation requirements.

WARNING!

Never connect unit to private (non-utility)

gas wells. This gas is commonly known as

wellhead gas.

FIREBOX LOCATION

Carefully select the best location for installation of your

vent-free rebox. The following factors should be taken

into consideration:

• Clearance to side wall, ceiling, woodwork and windows.

See “Clearances/Height Requirements on page 8. Mini-

mum clearances to combustibles must be maintained.

• Location must not be affected by drafts caused by

kitchen exhaust fans, ceiling fans, return air registers for

forced air furnaces / air conditioners, windows or doors.

• Installation must provide adequate ventilation and com-

bustion air.

• Location should be out of high trafc or windy or drafty

areas.

• DO NOT INSTALL WHERE CURTAINS, FURNITURE,

CLOTHING OR OTHER FLAMMABLE OBJECTS ARE

LESS THAN 42" FROM FRONT OF HEATER.

• Never obstruct the front opening of the vent-free rebox

or restrict the ow of combustion and ventilation air.

• Minimize modications to existing construction. Refer

to Figure 5.2 for location suggestions.

• Do not install in the vicinity where gasoline or other

ammable liquids may be stored. The vent free rebox

must be kept clear and free from these combustible

materials.
