pre-Installation preparation
selecting location
To determine the safest and most efficient location for the fireplace, you must take into consideration the following guidelines:
1.The location must allow for proper clearances (see Figures 6 and 7).
2.Consider a location where fireplace will not be af- fected by drafts, air conditioning ducts, windows or doors.
3.A location that avoids cutting of joists or roof raf- ters will make installation easier.
4.An outside air kit is available with this fireplace (see Optional Outside Air Kit on page 12).
Minimum clearance to combustibles
The distance to be maintained from the surfaces of the fireplace to combustibles must be observed.
Below is a list of the most common | combustible | |
materials to name a few: |
| |
Drywall | Wood Flooring | Plywood |
Wood Framing | Mill Board | |
Particle Board | Plywood Paneling |
|
Maintain the following clearances:
Unit sides, rear, Dome sides, rear & top.......... | 2" min. |
CombustibleFloors(MM33,39,44,49).............. | 6" min. |
Combustible Floors (MM63 only)..................... | 8" min. |
Combustible Sheathing above opening top..18" min.
Sheathing or trim to opening sides................... | 8" min. | ||||||
Mantel above opening.......................... | see Figure 5 | ||||||
Opening to sidewall............................................... | 24" | ||||||
Hearth extension beyond front............................. | 20" | ||||||
Hearth extension beyond sides............................ | 12" | ||||||
Insulation from firebox............................................ | 2" | ||||||

WARNING: Do not pack required air spaces with insulation or other materials.
Minimum/Maximum Chimney Height for Residential Installation
Minimum height of chimney, measured from base of fireplace to flue gas outlet of termination, is 14 feet for straight flue or 17 feet for a flue with one elbow set. Maximum distance between elbows is 6 feet. For systems with two elbow sets, minimum height is 22 feet. Maximum height of any system is 40 feet. This measurement includes fireplace, chimney sections and height of termination assembly at level of the flue gas outlet (see Figure 20, page 16).
Framing
1.Frame opening for fireplace using dimensions shown in Figures 6 and 7.
2.If fireplace is to be installed directly on carpeting, tile (other than ceramic) or any combustible material other than wood flooring, fireplace must be installed upon a metal extending full width and depth of fire- place.
3.Set fireplace directly in front of this opening and slide unit back until nailing flanges touch side fram- ing.
4.Check level of the fireplace and shim with sheet metal if necessary.
5.Before securing fireplace to prepared framing, ember protector (provided) must be placed between hearth extension (not supplied) and under bottom front edge of fireplace to protect against glowing em- bers falling through. If fireplace is to be installed on a raised platform, a
a minimum of 1 1/2". Ember protector should be made of galvanized sheet metal (26 gauge minimum to pre- vent corrosion.
6.Using screws or nails, secure fireplace to framing through flanges located on sides of fireplace.
