54.3 Operating instructions
 
54.3.1 The operating instructions required to be provided with each fireplace assembly are to be used as a reference during the examination and tests of a factory-built fireplace. The instructions are not required to be in final printed form for the investigation.

 
54.3.2 The operating instructions shall include particular details concerning:

a)     Operation with doors, when doors are provided with the fireplace. When the fireplace has been tested with doors, the instructions shall include the manufacturer's specific part numbers for doors that are used. When the fireplace has not been tested with doors, the instructions shall include the word "WARNING " and the following or equivalent statement: "THIS FIREPLACE HAS NOT BEEN TESTED FOR USE WITH DOORS. TO REDUCE THE RISK OF FIRE OR INJURY, DO NOT INSTALL DOORS."

b)     Operation with doors, to include a diagram and the word "WARNING " and the following or equivalent statement: "FIREPLACES EQUIPPED WITH DOORS SHOULD BE OPERATED ONLY WITH DOORS FULLY OPEN OR DOORS FULLY CLOSED. IF DOORS ARE LEFT PARTLY OPEN, GAS AND FLAME MAY BE DRAWN OUT OF THE FIREPLACE OPENING, CREATING RISKS OF BOTH FIRE AND SMOKE."

Exception: This warning shall be included unless gas and flame are determined not to be drawn out of the fireplace when the doors are in any possible opening position during the performance tests in this standard.

c)     Inspection, maintenance, and cleaning of the chimney including method of access through the top of the chimney (for example, method of removing chimney cap).

d)     Reference to the formation and removal of creosote buildup in the chimney as follows:

"Creosote - Formation and Need for Removal

When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited this creosote makes an extremely hot fire.

The chimney shall be inspected at least twice a year during the heating season to determine when a creosote buildup has occurred.

When creosote has accumulated it shall be removed to reduce the risk of a chimney fire. "

e)     Specifications on building the fire, maintaining the fire, and warnings against overfiring.

f)     Caution against the storage or use of flammable liquids, as follows:

"Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar liquids to start or 'freshen up' a fire in this fireplace. Keep all such liquids well away from the fireplace while it is in use."

g)     Clearances from the front of the fireplace to combustible materials.

h)     Disposal of ashes, including the following statement:

"Disposal of Ashes

Ashes should be placed in a metal container with a tight-fitting lid. The closed container of ashes should be placed on a noncombustible floor or on the ground, well away from all combustible materials, pending final disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all cinders have thoroughly cooled."

i)     Reference to the use or nonuse of grates, andirons, or other methods of supporting the fuel.

j)     Operation and use of manual damper controls.

k)     Operation and use of electrical assemblies.

l)     The use of fuels by including the following or equivalent statement: "Use (a) fuel only."

m)     The use of fireplace inserts and other nonspecified products by including the following or equivalent statement: "Do not use a fireplace insert or other products not specified for use with this fireplace." When the fireplace has been investigated and found to be capable of being used with a specified fireplace insert, or other specified product, the statement shall be modified as appropriate.

n)     A warning when processed solid fuel firelogs are used: "Do not poke or stir the logs while they are burning. Use only firelogs that have been evaluated for the application in fireplace and refer to firelog warnings and caution markings on packaging prior to use."

(a)Solid wood, processed solid fuel firelogs or other specified type of fuel.
