T he nailing strips can be adjusted back up to 1-1/2" (38mm) to allow for varying thicknesses in non-combustible material & wall finishes. The non combustible board is supplied to meet the requirements for this appliance. See non combustible section in the installation manual for details. - Page 3 U900E-11 Gas Fireplace Clearances The clearances listed below are minimum distances unless otherwise stated. A major cause of chimney related fires is failure to maintain required clearances (air space) to combustible materials. It is of the greatest impor- tance that this fireplace and vent system be installed only in accordance with these instructions.

Page 4: Mantel Leg Clearances
U900E-11 Gas Fireplace Mantel Clearances Due to the extreme heat this fireplace emits, the mantel clearances are critical. Combustible mantel clearances from top of front facing are shown in the diagram on the right. Note: Ensure the paint that is used on the mantel and the facing is "high quality" or the paint may discolour. -
Page 5: Non-Combustible Requirements
U900E-11 Gas Fireplace Non-Combustible Requirements * Installation of the ON/OFF Wall Switch/Battery Holder must be completed before installing non-combustible facing. All three pieces (top, 2 sides) may be ordered separately to meet the non combustible requirements. Calcium silicate board is a high - grade material with cement, quartz, natural and selected minerals as the main raw materials. It is widely used for partitions and ceilings in buildings. It is fire proof and earthquake proof. If finishing the wall above the unit with materials such as tile, brick, marble, etc. non-combustible board available from the building supply store can be used. NOTE: A minimum thickness Note: Calcium Silicate is 1/2' thick of 1/2" non combustible facing is required. Non-Combustible Facing Installation... -

Note: When constructing the framed opening, please NOTE: Spacing of 1"around the completed surround must be adhered to. ensure there is access to install the gas lines when the unit is installed. - Page 7 U900E-11 Gas Fireplace Framing & Finishing Important: Finished Nailing Strip Determine the nailing strip position by determining the facing material being used. Material Position 1/2" 1" Examples: Finished material (13mm) (25mm) 1/2" non-combustible wall board for clean finish =1" adjustment. Steel Stud 1/2" non-combustible wall board + 1/2" tile = 1" of finished material = 1/2" adjustment. Note: Unit Depending on the material used for finishing, the nailing strips must be set ac- cordingly so that the finished material is always at the 1-1/2" edge of the flange. 1" 1/2" Finished material Note : If material such as brick, stone, etc extends past the depth of 1-1/2" when (25mm) (13mm) finishing around the faceplate ( Inner/Outer faceplate/Verona glass surround), the minimum opening dimensions around the faceplate must be adhered to ensuring Steel Stud for the removal of the faceplate and for the safe operation of this appliance. See framing and finishing in this manual for details.

Page 9: Venting Introduction
U900E-11 Gas Fireplace Venting Introduction The U900E uses the "balanced flue" technology Co-Axial system. The inner liner vents products of combustion to the outside while the outer liner draws outside combustion air into the combustion chamber thereby eliminating the need to use heated room air for combustion and losing warm room air up the chimney. Note: These flue pipes must not be connected to any other appliance. The gas appliance and vent system must be vented directly to the outside of the building, and never be attached to a chimney serving a separate solid fuel or gas burning appliance. Each direct vent gas appliance must use it's own separate vent system. Common vent systems are prohibited. Venting Arrangement for Horizontal Terminations The diagram shows all allowable combinations of vertical runs with horizontal terminations, using one 90 (two 45 elbows equal one 90 elbow). Note: Must use optional rigid pipe adapter (Part# 510-994. when using Rigid Pipe Venting Systems. -

Page 12: Vertical Termination - Co-Linear Flex System Into A Masonry Chimney
U900E-11 Gas Fireplace Vertical Termination - Co-linear Flex System into a masonry chimney THE APPLIANCE MUST NOT BE CONNECTED TO A CHIMNEY FLUE SERVING A SEPARATE SOLID FUEL BURNING APPLIANCE. This appliance is designed to be attached to two 3" (76mm) co-linear aluminium flex running the full length of the chim- ney. See the "Venting Arrangements" section for minimum and maximum heights. NOTE: Maximum flue height is 30 feet. Masonry chimneys may take various contours which the flexible liner will accommodate. However, keep the flexible liner as straight as possible, avoid unnecessary bending. - Page 13 U900E-11 Gas Fireplace Venting Arrangements - Vertical Termination with Co-linear Flex System for both Residential & Manufactured Homes into Masonry Fireplaces The shaded area in the diagrams show the allowable vertical terminations.
