If your fireplace is equipped with an outside combustion air kit, keep it open at all times when fire is burning and close when fire is out to prevent cold air intrusion. Combustion Air Control The actuator for combustion air system is standard on all fireplaces but must not be operated if the complete system is not installed. See Figure 5and refer toFigure 2. If you have reason to believe that you do not have a complete outside combustion system, contact your distributor to have your fireplace inspected for the presence of the complete system before you use the combustion air actuator. DO NOT assume that you have this system in place because you have an actuating lever present on your fireplace front face. WARNING: DO NOT OPERATE THE COMBUSTION AIR ACTUATOR UNLESS A COMPLETE OUTSIDE COMBUSTION AIR VENT SYSTEM HAS BEEN INSTALLED WITH YOUR FIREPLACE. To provide outside combustion air to your fireplace while it is in operation, locate the combustion air actuator along the right side of the fireplace opening behind the screen. To operate, push the end of the actuator to the left as shown in Figure 5, until it "pops" free of its "locked" position. Pull the actuator forward to open the combustion air door, and push it back to close. NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE. To "lock" the combustion air door closed, ensure the actuator is pushed all the way back, then push the end of the actuators to the right until the step in the actuator moves behind the fireplace front face within the slotted opening. Combustion Air Actuator Pull Forward to Open, Push Back to Close Figure 5 REFRACTORIES All fireboxes contain a furnace refractory floor, sides and back. These refractories are reinforced with steel, but can be broken by improper use. Dropping logs on the bottom refractory and building fires directly against the refractories can cause premature burnout of these components. It may easily be repaired or replaced at costs far below repair and maintenance for masonry fireplaces. Proper care and “burn-in” of the firebox will prolong the period of enjoyment without extensive maintenance. For the first few uses, build small fires – not roaring infernos. The materials used in the refractories contain and absorb moisture. It is important to “cure” the refractories by building only modest fires. Under normal usage, it is expected that hairline cracks will appear in the refractory surface. These hairline cracks do not affect the safe operation of the fireplace. Refractories should be replaced when: 1. The crack opens more than 1/4" (19 mm). 2. Pitting in the surface is extensive and pits become deeper than 3/16" (4.76 mm). 3. Any piece of refractory larger than 2" (51 mm) in radius and 3/16" deep becomes dislodged. If conditions 1, 2 or 3 occur, the refractory should be replaced. MAINTENANCE GUIDELINES MAINTENANCE GUIDELINES Your fireplace will perform better – and certainly look more attractive to family and friends – if it is cleaned before each use. Before the first seasonal use in Autumn and after the last fire in Spring, it is important to inspect the fireplace system carefully. We recommend at least two complete fireplace inspections a year. Before Each Use 1. Clean the firebox of excessive ashes. Some owners prefer to leave a small layer to insulate the cold refractory below the grate which helps fire starting. This fireplace has a factory supplied grate attached, it is permissible to remove the grate for cleaning; however, the grate must be re-attached to the fireplace before the next burn. 2. Keep the fireplace screens clean so combustion air flows freely. 3. Spot check the brick-like refractory for small cracks. Heat from the fire expands it slightly. When it cools, it contracts. TWICE A YEAR CHECK-UP Normally, twice a year, you should inspect your fireplace following this list: 1. Inspect the opening in your chimney top and remove any debris that could clog it. The cap is usually held in place by four (4) screws, which remove easily for checking or cleaning the full length of the flue from above. Remove the chimney top while wearing gloves to guard against any sharp metal edges. 2. Inspect the entire flue from the top down for...
