2” Min Figure 3: Wall & Ceiling Minimum Clearances Wall and Ceiling Clearance Requirements: Ensure that minimum clearance shown in Figures 3 is maintained. Left and right clearances are determined when facing the front of the appliance. Follow these instructions carefully to ensure safe installation. Failure to follow these requirements may create a fire hazard. -
Page 9: Mantel Clearances
Mantel Clearances: A hood/canopy comes with every appliance. If a combustible mantel is installed, it must meet the clearance requirements detailed in Figure 4. Floor Clearances: The fireplace may be installed on a flat, hard combustible surface (i.e. flat wood, plywood, or particleboard). Be sure that the fireplace rests on a solid continuous floor of platform with appropriate framing support. -

Horizontal Venting with Three (3) Elbows: Figure 11: Horizontal Venting with Three (3) Elbows INSTALLING VENT COMPONENTS Before You Start: Plan your installation. Set unit in place and survey how best to vent the unit. Select the appropriate pipe for the installation. - Page 15 Two 45 elbows (P/N 945) may be used in place of one 90 elbow (P/N 990). Any horizontal run must have a 1/4” rise for every one (1) foot of run towards the vent termination. Never allow the vent to run downward. This could cause high temperatures and may present a fire hazard. Always maintain minimum clearances around vent systems.
- Page 16 For Ceiling For ceiling firestops, position a plumb bob over the center of the vertical pipe; to spot a hole through which the pipe will penetrate. Drill a hole through this centerpoint and check the floor for obstructions (i.e. wiring or plumbing). Reposition the fireplace and vent system, if necessary, to accommodate ceiling joists or obstructions.

Page 17: Vent Termination
Vent Termination: For Vertical Termination Figure 15: Minimum Vent Height for Various Roof Pitches Major building codes specify a minimum vent height above the rooftop depending on the pitch of the roof. Refer to the above figure for minimum heights, provided the termination cap is at least eight (8) feet from a vertical wall, and two (2) feet below a horizontal overhang. - Page 18 For Horizontal Termination Figure 16: Horizontal Vent Termination Location A=12 inches Clearance above the grade, a veranda, porch, deck, or balcony B=12 inches Clearance to window or door that may be opened. C=12 inches Clearance to permanently closed window. Vertical clearance to ventilated soffit located above the terminal within a horizontal D*=18 inches distance of 2 feet from the centerline of the terminal.
- Page 19 Always maintain minimum clearances around vent systems. The minimum clearances to combustibles for horizontal vent pipe are 3 inches at the top and 1 inch at the sides and bottom of the vent system. For wall firestops, a 1-inch minimum clearance all around the pipe must be maintained. Do not pack the open air spaces with insulation or other materials.
