CHIMNEY HEIGHT

The total height of your completed fireplace sys- tem from the surface the fireplace rests on to the chimney top must not exceed 80' (24.4m) and must also meet minimum height requirements. Refer to the minimum system height chart.

Chase Enclosure

A chase is a vertical box-like structure con- structed to surround the fireplace and chimney. Refer to Figure 2 for a typical chase configura- tion. As with all chimney installations, avoid overhead obstructions such as trees, power lines, etc. A chase should be constructed and insulated just like any outside wall. In a cold climate, we recommend the base of the chase should also be insulated between the solid continuous floor beneath the fireplace and the chase bottom. Chase insulation in a cold cli- mate installation is not required for safety.

LOCATION OF FIREPLACE

Carefully select the proper location for heat circulation, aesthetics, chimney obstructions and clearance to side wall(s). With proper pre- planning, a slight adjustment of a few inches can save considerable time and expense later during construction and assembly.

WARNING: IF INSULATION IS USED, THE FIREPLACE MUST NOT BE PLACED DI- RECTLY AGAINST IT. INSULATION OR VAPOR BARRIERS, IF USED, MUST FIRST BE COVERED WITH GYPSUM BOARD, PLYWOOD, PARTICLE BOARD OR OTHER MATERIAL TO ASSURE INSULATION AND VAPOR BARRIERS REMAIN IN PLACE.

WARNING: DO NOT PACK OR FILL RE- QUIRED AIR SPACES WITH INSULATION OR OTHER MATERIAL. NO MATERIAL IS ALLOWED IN THESE AREAS.

Note: Local codes may not require firestopping at the ceiling levels for outside chase installa- tions. However, it is recommended for safety and the reduction of heat loss.

ASSEMBLY OUTLINE

Before You Start

Check your inventory list to be sure you have all the necessary parts supplied in good usable condition. Check also for any concealed damage.

Check the operation of the damper. The damper is controlled through the use of a control lever located within the firebox opening at the top center just behind the firebox lintel (Figure 3 ).

Push back and up (away from the front of the fireplace) to lock the damper blade in the OPEN position. To lock the damper in the CLOSED position, the damper handle needs to be pulled down and forward (towards the front of the fireplace).

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Carefully consider the position of the fireplace opening with respect to the location of adja- cent or nearby stairwells, bath or kitchen ex- haust fans and/or return air registers for forced air furnaces/air conditioners that could cause a smoking fireplace condition if the house is tightly insulated.

When locating the fireplace, consideration must be given to combustibles and final finishing. See Figure 5 and confine the final location of combustible finish materials to the "Safe Zone".
