OPTIONAL EQUIPMENT
CONSIDERATIONS
Gas Line Connection
The EST-48 has been listed to accept a ¹⁄₂" gas line for an approved gas appliance. Always have the appliance installed in accordance with all local building codes.
CAUTION: ALL GAS CONNECTIONS SHOULD ONLY BE PERFORMED BY A QUALIFIED, LI- CENSED TRADESMAN. THE MAIN GAS SUP- PLY MUST BE OFF WHEN PLUMBING THE GAS LINE TO THE FIREPLACE OR WHEN PER- FORMING SERVICE WORK.
Install a ¹⁄₂" gas supply line through fireplace wall for connection to a decorative gas appli- ance inside the firebox. Outside, the gas supply line connects to a gas shut-off valve recessed flush into the wall or floor. The valve should be controlled by a removable valve key for safety.
Always plumb gas line installation per local codes. Check all connections with soap suds; leaks will bubble. Never test any gas line con- nection with a match or open flame.
This provision is intended for connection to a decorative gas appliance incorporating an au- tomatic shut-off device and complying with the Standard for Decorative Gas Appliances for installation in vented fireplaces, ANSI Z21.60 (1991) or American Gas Association draft re- quirements for Gas-Fired Log Lighters for Wood Burning Fireplaces, Draft No. 4 dated August, 1993. Install in accordance with the National Fuel Gas Code, ANSI Z223.1. This complies with the revised U.L. 127 standard.
Vent Free Appliances
These units have been tested and approved to ANSI/IAS/AGA Z21.11.2 for use with unvented gas appliances and complies with the stan- dard for Factory-Built fireplaces, UL 127.
The unit has been tested for use with any unvented gas log sets having a maximum rating of 40,000 BTU. The minimum mantle configurations are outlined in Figure 43.
These fireplaces have been marked with a maximum rating of 40,000 BTU to assure that homeowners do not exceed the allowable lim- its for all allowed installations of mantles.
NEVER INSTALL AN UNVENTED GAS LOG SET WITH A BTU GREATER THAN 40,000.
CAUTION: WHEN USING THE DECORATIVE GAS APPLIANCE, THE FIREPLACE DAMPER MUST BE SET IN THE FULLY OPEN POSITION.
CAUTION: PLUMBING CONNECTIONS SHOULD ONLY BE PERFORMED BY A QUALIFIED, LI- CENSED PLUMBER. MAIN GAS SUPPLY MUST BE OFF WHEN PLUMBING GAS LINE TO FIRE- PLACE OR PERFORMING SERVICE.
If you’re installing a gas line, connect it before the fireplace is framed and enclosed in the finished wall. The gas knockout is determined by the indentation located at the bottom and slightly off center in the side refractories. THE
KNOCKOUT IS ALWAYS REMOVED FROM IN- SIDE THE FIREPLACE. DO NOT REMOVE THE KNOCKOUT UNLESS YOU ARE INSTALLING A GAS LINE. If removal is attempted from the outer wrapper, side refractory damage may occur. With a medium-sized hammer, lightly tap the surface of the indentation. The refrac- tory material is very thin in this area and is easily removed. Once a small hole has been made, continue tapping until you have reached suffi- cient diameter for the gas line to fit through. The entire knockout does not have to be removed. Remove insulation in the gas line channel.
IMPORTANT: REPACK INSULATION MATERIAL IN SQUARE HOLE AROUND GAS LINE, INTE- RIOR AND EXTERIOR OF FIREPLACE, TO SEAL.
Glass Doors
If glass doors are to be installed on these fireplaces, refer to specific installation instruc- tions packed with the glass doors. Use only the doors that are listed for use with these fire- places. Use of other non-listed glass door on these fireplaces may constitute a potential fire hazard and is not recommended.
CAUTION: CERTAIN GLASS DOORS OVER- LAP THE BLACK METAL FACING OF THE FIRE- PLACE. IF THE FIREPLACE HAS BEEN FACED WITH NONCOMBUSTIBLE MATERIALS, THERE MIGHT NOT BE SUFFICIENT CLEAR- ANCE TO INSTALL THE GLASS DOORS OF YOUR CHOICE. ENSURE ADEQUATE CLEAR- ANCE IS MAINTAINED AT ALL TIMES SO AS NOT TO INTERFERE WITH THE INSTALLA- TION AND OPERATION OF GLASS DOORS.
COLD CLIMATE INSULATION
If you live in a cold climate, it is especially important to seal all cracks around the fire- place opening with noncombustible material and wherever cold air could enter the room.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Surrounding materials must be caulked where it meets the black metal facing of the fireplace to avoid cold air intrusion. Use noncombus- tible caulking material only on fireplace facing to seal. Also, the outside air inlet duct should be wrapped with noncombustible insulation to minimize the formation of condensation. Do not place insulation materials on top of fire- place or against chimney sections.
Note: A 2" air space must be preserved for all combustible materials extending for any con- tinuous length adjacent to the chimney.
It is especially important to insulate between the studs of an outside chase cavity and under the floor if the floor is above ground level. Do not place insulation directly against the fire- place or chimney system.
FIREPLACE FINISHES
Mantels and Trim
It is sometimes best to frame your fireplace after it is positioned and the chimney is in- stalled. Frame enclosure for chimney and fire- place with 2 x 4’s (or heavier) lumber.
Note: The header may rest on the two (2) metal top spacers on top of the unit but the header must not be notched to fit around the spacers.
These fireplaces may sit directly on a combus- tible surface. A 2" air space is required be- tween combustible framing and the chimney. Combustible mantels and trim may be in- stalled 12" above the fireplace opening as per NFPA 211, Section 7-2.3.3. and Figure 43. If a mantel is of a noncombustible material, it is exempt from these requirements as long as it does not interfere with the installation or op- eration of glass doors.
