User Guide 2 Operating Instructions WARNING HOT SURFACES! Glass and other surfaces are hot during operation AND cool down. Hot glass will cause burns. • DO NOT touch glass until it is cooled • NEVER allow children to touch glass • Keep children away • CAREFULLY SUPERVISE children in same room as fireplace. • Alert children and adults to hazards of high temperatures. High temperatures may ignite clothing or other flammable materials. • Keep clothing, furniture, draperies and other flammable materials away.
B. Seasoned Wood D. Grate Properly seasoned wood is important for successful operation of your fireplace. Most woodburning fireplace problems are caused by burning wet, unseasoned wood. This fireplace is designed to be used with the grate supplied with this unit or one approved by HHT. The grate will break down over time and will need occasional replacement. Seasoned firewood is wood that is cut to size, split and air dried to a moisture content of around 20%.
H. Glass Doors J. Vented Gas Log Sets & Gas Log Lighters • • • • Glass doors are optional. Refer to Figure 2.2 for how to properly use them. WARNING! Risk of Fire! Install ONLY doors approved by Hearth & Home Technologies, Inc. Optional Vented gas logs or gas log lighters can be installed in this fireplace. Follow the instructions provided with the accessory for operation. WARNING! Risk of Fire or Asphyxiation! • DO NOT install unvented gas logs. • Damper must be locked open.
M. Wood Fuel Seasoned Wood Hardwood vs Softwood • • • Your fireplace performance depends on the quality of the firewood you use. • • • • • • • Seasoned wood contains about 8,000 BTUs per pound . Hard woods are more dense than soft woods. Hard woods contain 60% more BTUs than soft woods. Hard woods require more time to season, burn slower and are harder to ignite. Soft woods require less time to dry, burn faster and are easier to ignite.
3 Maintainance and Service A. Disposal of Ashes B. Chimney Inspection/Cleaning Frequency: When they reach bottom of grate By: Homeowner Frequency: At least twice a year during heating season or as recommended by a certified chimney sweep By: Certified chimney sweep WARNING! Risk of Fire! Ashes could contain hot embers. • • • Place ashes in a metal container with a tight-fitting lid.
C. Check Firebox Refractory Frequency: After each ash removal By: Homeowner WARNING! Risk of Fire! Inspect fireplace refractory. Crumbling, deteriorated refractory can allow overheating of surrounding materials. Expansion and contraction will cause minor cracking of the refractory. This is normal. The refractory will require periodic replacement depending on use.
4 Troubleshooting Guide Start Fire Problems Possible Cause Solution Can’t get fire started Excessive smoke or spillage Burns too slowly Smolders, sizzles Not enough kindling/paper or no kindling/paper Use dry kindling, more paper. Arrange kindling & wood for air movement. Damper closed/not fully open Open damper. Not enough air for fire to ignite Check for restricted cap/shroud. Open air kit (if installed). Check for flue blockage.
Installer Guide 5 Getting Started A. Typical Fireplace System Additional lateral support for chimney above roof (or enclosed in chase) if needed (Section 8) NOTICE: • Illustrations and photos reflect typical installations and are for design purposes only. • Illustrations/diagrams are not drawn to scale. • Actual product may vary from pictures in manual.
B. Design and Installation Considerations D. Negative Pressure NOTICE: Check building codes prior to installation. WARNING! Risk of Asphyxiation! Negative pressure can cause spillage of combustion fumes and soot. Fire must draft properly for safe operation. • Installation MUST comply with local, regional, state and national codes and regulations.
E. Locating Fireplace & Chimney Location of the fireplace and chimney will affect performance. • • • • • • Install within the warm airspace enclosed by the building envelope. This helps to produce more draft, especially during lighting and die-down of the fire. Penetrate the highest part of the roof. This minimizes the effects of wind loading. Locate termination cap away from trees, adjacent structures, uneven roof lines and other obstructions. Minimize the use of chimney offsets.
F. Tools and Supplies Needed H. Inspect Fireplace and Components Before beginning the installation be sure the following tools and building supplies are available: Reciprocating saw Framing material WARNING!

Figure 7.3 Possible Outside Air Inlet Locations NO NO Outlet blocked by snow, leaves, etc.
E. Install Outside Air Kit • • • • • • Keep duct runs short and straight to minimize restriction. A small dip is acceptable for a cold air trap. The outside air kit must be installed. Locate the outside air hood in a clear area, preferably into prevailing wind during the heating season. Refer to Figure 5.2. Install as shown in Figures 7.3, 7.4 and 7.5. The air duct may be run vertically. The outside air hood must be at least 3 ft (.91 m) below the top of the uppermost chimney section.
8 Chimney Assembly NOTICE: Chimney performance may vary. • Trees, buildings, roof lines and wind conditions affect performance. • Chimney height may need adjustment if smoking or overdraft occurs.
A. Chimney Requirements Measure vertical distances from the base of the fireplace as shown in Figure 8.2. ft meters • Minimum overall straight height 14 4.27 • Minimum height with offst/return 16.5 5.03 • Maximum height 90 27.43 • Maximum chimney length bewtween an offset and return 20 6.10 • Maximum distance between chimney stabilizers 35 10.67 • Double offset/return minimum height 20 6.10 • Maximum unsupported chimney length between the offset and return 6 1.
B. Using Offsets/Returns • • Use an offset/return to bypass overhead obstructions. An offset and return can be used as a single entity or separated by chimney section(s). WARNING! Risk of Fire! DO NOT use offset/returns greater than 30°. Chimney draft will be restricted and could cause overheating and fire. • • • • Measure the shift needed to avoid the overhead obstruction. Refer to dimension A in Figure 8.3. Find the appropriate A dimension listed in Table 8.2.
C. Assemble Chimney Sections WARNING! Risk of Fire! DO NOT install substitute or damaged chimney components. • Use only those components described in this manual. Substitute or damaged chimney components could impair safe operation and cause overheating and fire. • • • Support the pipe during construction and check to be sure inadvertent loading has not dislodged the chimney section from the fireplace or at any chimney joint. Attach a straight chimney section or an offset to the top of the fireplace.
E. Install Ceiling Firestops ROOM ABOVE (non-insulated ceiling) CAUTION! Risk of Fire! Ceiling firestops must be used whenever the chimney penetrates a ceiling/floor. • • • • • • • Chase construction requires ceiling firestops at each floor or every 10 ft (3.05 m) of clear space. The ceiling firestop slows spread of fire and reduces cold air infiltration. Install a ceiling firestop whenever chimney penetrates ceiling/floor. Mark and cut an opening in ceiling as shown in Figure 8.5.
F. Install Attic Insulation Shield WARNING! Risk of Fire! You MUST install an attic insulation shield when there is any possibility of insulation or other combustible material coming into contact with the chimney. • DO NOT pack insulation between the chimney and the attic insulation shield. • Failure to keep insulation and other materials away from chimney pipe could cause fire. • DO NOT offset chimney inside insulation shield.
G. Cut out Hole in Roof • • • • • • • Refer to Figure 8.9. Plumb from roof to center of chimney. Drive a nail up through roof to mark center of pipe. Measure to either side of nail and mark the 14-1/2 in. x 14-1/2 in. (368 mm x 368 mm) opening required. Measure opening on the horizontal; actual length may be larger depending on roof pitch. Cut out and frame opening. Refer to Chapter 25 of the Uniform Building Code for roof framing details. H.
