Owner's Manual Residential Factory Built Fireplace Operation • Maintenance • Installation The ONYX AP Keep these instructions for future use.
Dear Customer, The ONYX AP fireplace incorporates technology with elegance to give you a beautiful view of the fire without compromising on heating efficiency or environmental quality. We have designed your new ONYX AP to be easy to install, operate and maintain. It is in your best interest to become familiar with it. Study your manual to be sure the installation is correct, then follow the guide for operation and maintenance.
SAFETY FIRST DO'S AND DON'TS If this fireplace is not properly installed, a house fire may result. For your safety, follow the installation directions. Contact local building or fire officials about restrictions and installation requirements in your area. NOTE: We strongly recommend installers to be WETT in Canada, and by NFI in USA. To ANYONE using this fireplace: These DO's and DO NOT's are for your safety. 1. DO read this instruction manual before lighting your first fire. 2.
GENERAL SPECIFICATIONS THE COMBUSTION CONTROL SYSTEM Since the door is sealed, all combustion air must come through a draft control. This control has a bimetal coil to allow more air when the unit is cold and less when hot, guarding against overheating. It is controlled either manually through the lever below the door handle or through an optional electric wall thermostat. To achieve a low burn, close draft control completely by moving the control all the way to the left.
CENTRAL HEAT SYSTEM (option) You have the option to heat remote rooms in your home with the heat generated by your fireplace. If this option is installed, there will be a wall thermostat installed in the main room you want to heat, away from the room which contains the fireplace. This thermostat controls the blower, which brings air to the other rooms in your home, keeping them at the temperature you desire.
should be then placed in the bottom of the firebox. The baffle for the Onyx AP is in two pieces (11.6.N) and is easily put into place at the top of the firebox. The secondary air tubes must be first removed. The two small front refractories (11.4.N & 11.5.N) are then placed in their appropriate positions. These directions should be reversed in order to remove the refractory from the Onyx AP. MAINTENANCE CLEANING The high heat paint and gold plating can be cleaned with a soft moist cloth.
GLASS In a controlled combustion firebox temperatures are not always high enough to keep the glass clean. We have supplied you with special ceramic glass, which will withstand the heat from the fireplace without cracking. A good hot fire in the morning usually cleans most of the soot accumulated during the night. You can also purchase stove glass cleaner from your local speciality fireplace retailer. Remember the drier the wood, the cleaner the glass. Be careful not to hit the glass.

Prepare the unit for installation. The holes in the side stand-offs have been elongated to allow easy alignment of the framing and the fireplace sides.
CAUTION: When running duct around corners, be sure to prevent crimping that would restrict the combustion airflow. Use an insulated duct rated at over 200° F. Our testing has shown that as long as the 5" diameter insulated duct is utilized properly, there is no restriction on the length of the run. It is recommended that the duct does not exceed 12 ft. vertical height rise above the base of the unit. The air inlet should never be less than 5 ft.
We recommend that the minimum height be increased by approximately 1 ft. for every 2000 ft. elevation above sea level. Every 30° or 45° elbow also increases the minimum height by 1 ft. For example, if you are living 6000 ft. above sea level, your chimney should terminate at least 15 ft. from the top of the fireplace (12 ft. + 3 ft. for the 6000 ft.). See Table #1 for more precise recommended flue heights.
MASONRY CHIMNEY Warning: When contemplating using an existing chimney, it must first be thoroughly inspected by an authority having jurisdiction to determine the following: 1. It is a well constructed, lined Excel liner or other liner listed to ULC-S635, ULC-S640 or UL1777 masonry chimney, fully in accordance with Local Building Codes and the National Building No comCode of Canada (NBCC) 9.21 or 12” min. to bustible combustible NFPA 211 material in ceiling 2.
to the Excel chimney with the 3 screws provided. The stainless steel liner fits inside the clay liner all the way to the top of the masonry chimney. It is not meant to replace the clay liner. After mortaring in place, the connection should not be visible. Care must be taken when cleaning to ensure that the stainless steel flex liner is not dislodged. As depicted in (Figure 9), the metal chimney is to be a minimum of 18" from the connection point at the elbow to the masonry adaptor.
NOTE: If the chase is enclosed or flashed to a roof as shown in (Figure 10), then the flashing must be vented. If required by local codes, make certain that the walls have been properly insulated, vapor sealed and sheathed with a fire rated gypsum board (See Figure 11). REMEMBER: Check local codes concerning installation requirements and restrictions in your area. RADIATION SHIELD A radiation shield must be in place where the chimney passes through each floor level overhead.
BENEATH HEARTH EXTENSION Unless raised 4” above the base of the hearth, the Onyx AP must use a 1/2” Durock ciment board with a metal sheet (0.025”) or a 3/4” Micore 160 board beneath the hearth extension (non-combustible material). If the fireplace is raised 4" or more, the area in front of the fireplace just needs to be covered with a non-combustible material, such as metal, brick, stone or slate. There is no minimum thickness required for this noncombustible hearth extension.
ONYX AP OPTIONS Just a few comments about your Onyx AP options. The size and shape of your home and how you intend to use your fireplace will determine the options you require. For a basic, high-efficiency fireplace, you won’t need any options or electricity. Automatic temperature control can be accomplished by adding the thermostat option (part FDHC4). The thermostat automatically controls the amount of combustion air to the fire, leaving your home at an even preset temperature.
chain that is beside it. Let the chain down on the same side of the inner heat shield as the existing one and attach it to the lever on the damper motor with another pendant. Push the pendant snug into the hole in the lever. Then mount the controls to the bracket. 4. Adjust the chain on the draft control lever until it is just snug and the damper is still closed. When the damper motor is energized, the damper should open all the way.
6. Slide the blower into place between the two brackets. You should be able to see the wheels of the blower. 7. Mount the thermal switch on its support as shown in (Figure 18). The thermal switch support is located just beneath the bottom of the firebox on the right hand side leg. Push the clips on to the support as far as they will go. NOTE: One thermal switch is all that is required to operate the internal blower, the central heat blower, or both. 8.

Using a plasterer or mason's trowel, apply a scratch coat that covers the wire mesh. Let the mortar set before adding another coat. This will take several hours. Afterwards, apply a thinner coat and the facing. Do not spread plaster over more than a workable area so that the mortar will not set before the facing is applied. 5.

3) Part FDHB6: a maximum 636 C.F.M. blower with a variable speed motor, 2 noise reduction collars, a blower speed control and a mounting bracket and a back draft damper. NOTE: the 3 parts FDHC6, FDHC6-1, FDHB6, must be used together for this system. Use of any substitutes will de-certify the system. The 8” back-draft damper prevents hot air from travelling into the ‘C’ vent (single wall) ducting unless the Central Heat Blower (FDHB6-1) is operating.
space and minimize cost. Maximum duct length should not exceed 50 feet from the fireplace to the furthest outlet. There is a loss of about 15% performance at 50 feet. Also: The blower automatically shuts off if the air temperature reaches 180° F inside the ducting. 5. Locate the blower in a convenient location. The blower may be installed vertically or horizontally.

Blower control central ZONE HEATING (FDHCZ1 AND FDHCZ2) For more regional heat control, the Onyx AP is ideally suited for Zone Heating. (Figure 33) shows an example of a three-zone system. The thermostat simultaneously opens the desired valve and starts the blower when heat is required.
6. Follow the instructions supplied with your gas log set concerning the installation of gas lines, shut-off valves, etc. If you have the sand pan type of gas log set that covers the air holes, place some of the firebrick, or some other suitable non-combustible material around the edges of the sand pan to raise the gas log set above the air holes. Maximum gas input: 40 000 BTU There are no minimum clearances to the sides or top of the firebox.
