• Electrical Input
  The electrical input should be set at 3 1/4 inches (83 mm).

• Minimum Venting Requirements
  At least 21 inches (533 mm) of clearance is required above the vent when passing through an exterior wall when horizontally terminating. The first elbow only requires 36 inches (914 mm) of clearance. A minimum of 15 inches (381 mm) of non-combustible zone is necessary.

• Mantel Projections
  The mantel height can be adjusted between 36 and 68 inches. The mantel depth can be adjusted between 44 and 68 inches.

• Cool Surface System Framing
  The minimum framing dimensions for the Cool Surface System are 1346 mm. Option 1 involves a front discharge with a minimum gap of 53 inches by 3 inches at the top of the facing wall. Option 2 is an open chase with a minimum framing dimension and vented ceiling. Optional 3: Valance can be used in conjunction with Option 2.

• Wall Mounted Object
  A minimum clearance of 3 inches is required for any wall-mounted object.

Non-Combustible Board Placement

Minimum Venting Requirements

• This appliance uses a 11” (280 mm) exhaust / 8” (203mm) air intake vent pipe system. For safe and proper operation of the appliance follow the venting instructions exactly. Deviation from the minimum vertical length can create difficulty in burner start-up and sooting. Allow several minutes for the flame to stabalize after ignition under extreme vent configurations. It is recommended for vent lengths that pass through unheated spaces (garages, attics, crawl spaces) be insulated to minimize condensation.
• NOTE: At least 21 (533mm) of clearance is required above vent when passing through an exterior wall when horizontally terminating.

Fireplace Dimensions

Mantel Projections

Mantel graph dimensions are measured from the bottom of the fireplace, if you wish to reference the mantel height from the tiling edge subtract 45 inches (1143mm) from the mantel height depicted on the graph. If you plan to install a TV above your fireplace refer to the appropriate section of the owner’s manual for available options. It is acceptable to install a combustible mantel over top of the non-combustible board. If using the Cool Surface System, refer to the graph on the following page to determine the required mantel height.

Mantel Projections with Cool Surface System
Activating the Cool Surface System decreases the required height of the mantel. Use the graph on the right to determine the mantel height when using the Cool Surface System. Mantel graph dimensions are measured from the bottom of the fireplace, if you wish to reference the mantel height from the tiling edge subtract 45 inches (1143mm) from the mantel height depicted on the graph. If you plan to install a TV above your fireplace refer to the appropriate section of the owner’s manual for available options. It is acceptable to install a combustible mantel over top of the non-combustible board.

Cool Surface System Framing

• Framing Option 1: Front Discharge (flush wall installations)

  • Construct the framing in a way that provides a minimum 53 inch (1067mm) by 3 inch (76mm) gap at the top of the facing wall. It is essential that these dimensions are respected and not to deviate away from them when using combustible materials inside the chase (see Figure 1).
  • Note: If you wish to construct the CSS air discharge part way up a tall wall then it is essential to build a false ceiling inside the chase at the desired height to direct the rising heat out of the gap.

• Framing Option 2: Open Chase (built-out installations)

  • This could be considered the most discreet option when considering the CSS. The chase must be constructed in a way that stops short of the ceiling, leaving it totally vented above.
  • Minimum framing dimensions must be followed when constructing this option and not to deviated from them when using combustible materials. Consider Optional 3: Valance to work in conjunction with this option.

• Framing Option 3: Valance
  A valance may be desired to accentuate or hide the CSS outlet. Consider framing option 1 or 2 to utilize the valance feature. This is an optional decorative feature that covers up the CSS outlet gap. Minimum opening and valance dimensions must be followed to ensure safe heat dissipation. Combustible materiel is acceptable when constructing the valance. It is acceptable to wrap the valance around the three sides of a built out chase (Option 2).

• Framing Option 4: Side Discharge
  Construct the framing in a way that provides two gaps, one on each side of the chase as shown in Figure 7. Each gap should be a minimum of 21 inch (533mm) by 3 3/4 inch (95mm). It is essential that these dimensions are followed and not to deviated from them when using combustible materials inside the chase (see Figure 6).

• Optional: False Ceiling
  If your ceiling dimension is greater than the minimum (See Figure 1) You may want the CSS air discharge lower on the wall. This false ceiling is required to properly evacuate heat from the chase. (See Figure 8).
