• Adjust framing dimensions for interior sheathing (such as sheetrock) ** Fireplace may need to be elevated from the floor affecting framing height B, depending on hearth construction. See Section 3.D for hearth and combustible floor requirements. For installations with vinyl flooring, special clearance requirements apply. See Section 3.E.

Figure 3.4 Clearances to Combustibles

C. Constructing the Appliance Chase
A chase is a vertical box-like structure built to enclose the gas appliance and/or its vent system. In cooler climates the vent should be enclosed inside the chase. NOTICE: Treatment of ceiling firestops and wall shield firestops and construction of the chase may vary with the type of building. These instructions are not substitutes for the requirements of local building codes. Therefore, you MUST check local building codes to determine the requirements to these steps.
NOTICE: Where required by code, install only sprinkler heads with a sprinkler activation temperature classified as Extra High.
· Sprinklers inside of chase: Keep sprinkler head away from vent and chimney.
· Heat Management applications: Maintain 36 inches of clearance to openings from which heat is discharged such as heat zone registers, etc.
Chases should be constructed and insulated in the same manner as the thermal envelope of the home based on the code requirements for that climate zone to prevent air leakage and draft problems. The chase is an extension of

the building thermal envelope.
To further prevent drafts and air leakage, the wall shield and ceiling firestops should be caulked with caulk with a minimum of 300 ºF continuous exposure rating to seal gaps. Gas line holes and other openings should be caulked with caulk with a minimum of 300 ºF continuous exposure rating or stuffed with unfaced insulation. If the appliance is being installed on a cement surface, a layer of plywood may be placed underneath to prevent conducting cold up into the room.
NOTICE: Install appliance on hard metal or wood surfaces extending full width and depth. DO NOT install directly on carpeting, vinyl, tile or any combustible material other than wood.
WARNING! Risk of Fire! Maintain specified air space clearances to appliance and vent pipe:
· Insulation and other materials must be secured to prevent accidental contact.
· The chase must be properly blocked to prevent blown insulation or other combustibles from entering and making contact with fireplace or chimney.
· Failure to maintain airspace may cause overheating and a fire.

D. Hearth Extension
WARNING! Risk of Fire! Hearth extension required to protect combustible floors in front of appliance.
WARNING! Risk of Fire! DO NOT block ventilation slots. A minimum 1/4 in. space between the bottom of hearth refractory and top of field installed hearth extension (marble, tile, granite, etc) is required across full width of fireplace.
If the appliance is to be placed directly on the floor, the non-combustible hearth material will be limited to 3/4 in. thick, including the floor adhesive. If the hearth material will exceed 3/4 in. thick, the appliance will need to be shimmed from the floor appropriately to maintain 1/4 in. minimum space between the floor hearth and hearth refractory.
The base of the fireplace may sit on a combustible surface. The area in front of the fireplace must be protected by a noncombustible hearth extension, unless the fireplace is raised a minimum of three inches above the combustible floor or hearth. See Figures 3.5, 3.6 and 3.8.

E. Floor Protection
Vinyl Flooring
Vinyl flooring is sensitive to heat. To avoid damage to the vinyl flooring, a 12 inch minimum x 12 inch minimum hearth is recommended when using vinyl flooring up to the wall. See Figure 3.9. If no hearth is used, it is recommended to provide a minimum of 36 inches of clearance in front of the appliance to the vinyl flooring OR the bottom of the appliance should be raised a minimum of 24 inches off of the floor to allow the vinyl flooring to be installed up to the wall.
NOTICE: Clearances that do not meet the minimum guidelines could result in damage or buckling to the vinyl flooring and is done at the installer’s risk.
Hearth and Home Technologies does not recommend adhesive based vinyl flooring products due to thermal expansion during operation. Floating style flooring can be used, but will reach temperatures up to 110 °F (based on ambient temperature of 70 °F). Consult the manufacturer’s flooring specifications to ensure compatibility.

I. Mystic Ember Placement
WARNING! Risk of Explosion! Follow ember placement instructions in manual. DO NOT place embers directly over burner ports. Replace ember material annually. Improperly placed embers interfere with proper burner operation.
Ember material is shipped with this gas appliance. Use this material to give the appliance a realistic ash bed. To place the ember material:
1. Place Mystic Embers in a random pattern around the base refractory away from port holes as shown in Figure 11.23.
2. Save the remaining ember materials for use during appliance servicing. The embers provided should be enough for 3 to 5 applications.

Figure 11.20 Glass Ember Bed
2. Using TUP-GBK-12 spray paint, dust the glass ember rock to create a more natural looking ash bed. Care should be taken to avoid overspray onto refractory, stainless steel back plate, or pilot. See Figure 11.21 and Figure 11.22.
