CHIMNEY OFFSET 30° THROUGH FLOOR

OR CEILING

It may be necessary to assemble the chimney at 30° when passing through the floor or ceiling area. Use the F8FS30-2 firestop spacer as shown in Figures 50 and 51.

Support the chimney at floor or ceiling penetration with a FTF8 stabilizer if distance of chimney below ceiling is 10' (3 m) or more. Maintain 2" (51 mm) minimum air space to combustibles from chimney sections. The chimney must pass vertically through the attic space.

GLASS DOORS

Both the CST and CPF fireplaces require the use of glass doors. The selection of glass doors available for use with these fireplaces are: 38ABF, 38ABF-BB and 38TBA-BB. For the CPF system, end panels model 38AEP and 38AEP-BB are available. Refer to the Suggested List Price Sheet. The use of any other non-listed door on these fireplaces may result in a potential fire hazard and is not recommended.

IMPORTANT: IT IS NECESSARY TO ORDER AND INSTALL THE DOOR STYLE OF YOUR CHOICE. GLASS DOORS ARE NOT OPTIONAL.

CAUTION: REMOVE THE PLASTIC PROTECTIVE COATING FROM THE DOORS BRASS PIECES BEFORE ASSEMBLY AND INSTALLA- TION. FAILURE TO REMOVE THE COATING BEFORE FIRST USE WILL RESULT IN DAMAGE TO THE BRASS FINISH.

Make a careful inspection of all parts before installing the doors to insure they are undamaged and complete. There will be two (2) glass door assemblies for both sides of the CST-38 fireplace and two (2) glass door assemblies plus one (1) end panel for the CPF-38 fireplace.

CAUTION: DO NOT TOUCH THE DOORS WITH YOUR HANDS WHILE THE FIREPLACE IS IN USE. ALWAYS USE DOOR HANDLES. DOORS WILL BECOME VERY HOT WHEN FIREPLACE IS IN USE.

Note: Design characteristics of a dual-opening fireplace (whether masonry or factory-built) may cause it to not draft properly and smoke. For this reason, glass doors are required with Models CST-38 and CPF-38 fireplaces.

WARNING: THESE FIREPLACES SHOULD BE OPERATED ONLY WITH THE DOORS FULLY CLOSED (FIGURE 52 ).

OPTIONAL EQUIPMENTCombustion Air Kit

Use combustion air kit, Model AK-4 or AK-4LD (Figure 53 ), with these fireplace sys- tems. Refer to installation instructions packed with the air kit for specific information. Outside air drawn into the fireplace supplies air to the fire for combustion. The outside air kit must be installed before the fireplace is framed and enclosed in the finished walls.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

There is a one-hand operated shut-off valve located in the enclosed corner of the fireplace opening behind the screen. Refer to label for directions of operation. The combustion air damper should be fully open when the fireplace is in operation and fully closed when the fireplace is not in use to prevent outside air from entering your home.

If additional length of duct is necessary, purchase locally available Class 0 or Class 1 duct- ing. The duct may extend up to 50' (15.2 m) in any direction.

Combustion

Air Kit

Figure 53

Outside combustion air may be run upwards or vertically through framing and ceiling joists, with the hood installed through an outside wall and 3' (914 mm) below the termination. Ducting may also be run downward through floor joists and under the home to a ventilated crawlspace not considered part of the living area of the home.

CAUTION: NEVER LOCATE THE AIR INLET WHERE IT COULD BE BLOCKED BY SHRUBS, SNOW DRIFTS, ETC. NEVER LOCATE THE AIR INLET IN GARAGE OR ANY AREA WHERE THERE IS ANOTHER FUEL BURNING APPLIANCE OR PRODUCTS EMITTING COMBUSTIBLE GASES SUCH AS PAINT, GASOLINE, ETC. IN COLD CLIMATES, IT IS RECOMMENDED THAT THE COMBUSTION AIR DUCT BE INSULATED.

Note: Do not terminate combustion air kit in attic space under any circumstances.

CAUTION: IN NO EVENT MAY THE TOTAL DUCT FOR BRINGING IN OUTSIDE AIR EXCEED 50' (15.2 M).
