Monessen Hearth 3000 SERIES ユーザーズマニュアル

Combustible Materials - Materials made of or surfaced with wood, compressed paper, plant fibers, or other 
materials that are capable of being ignited and burned. Such materials are considered combustible even 
though flameproof, fire retardant, treated, or plastered. 
 
Non-Combustible Materials - Materials which will not ignite and burn. Such materials are those consisting 
entirely of steel, iron brick, tile, concrete, slate, glass, marble, or combination thereof, or have a UL Fire 
rating of Zero (0). 
 
High Temperature Sealant Material - Sealant that will withstand high temperature; General Electric 
RTV103 or equivalent. 

 
Finishing the fireplace flush with a wall: 
 
When finishing the face of the fireplace, combustible material may be brought up to the sides of the fireplace, but 
must never overlap onto the black metal face. The black metal face may be covered with non-combustible material 
only. However, the louvers must never be covered with finishing materials. After applying the finishing material, a 
non-combustible sealant, 1/8” minimum, must be used to close off any gaps at the top and sides between the 
fireplace and the finishing to prevent cold air leaks. Refer to Figure 7: Finishing Material section in this manual for 
allowable locations for combustible materials. 

Installation Components On Fireplace: 
 
Hood Installation 
 

 

All fireplaces come with a hood. Remove the hood 
from the top of the unit. To install, locate the three 
holes on the underside of the top outer shell, near 
the top louvers. Remove the top louver and use the 
three screws supplied to attach hood. See Figure 
26: Hood Installation.  Re-install the top louver.
