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.

Side-wall Clearance: The clearance from the front edge of the appliance to any combustible wall should not be less than 2” on both the left and right side. Ceiling Clearance: The ceiling must be at least 31” from the top of the front of the fireplace (65.5” from the bottom of the appliance). Refer to Figure 3. Back-wall Clearance: The appliance may be placed against a combustible back wall. NOTE: There are 1/4” ribs/spacers on the outer shell of the unit to maintain minimum clearance of the outer shell to combustibles.

Combustible Clearances:

The appliance is a zero clearance fireplace with ribs/spacers defining the minimum space to the sheet metal outer shell. Combustibles may be placed up against these spacers. Do NOT place combustibles (i.e., insulation, wood, etc.) closer than allowed by the spacers or a fire hazard may exist. The ribs/spacers for the sides and rear of the appliance are 1/4” and the top spacers are 3 1/4”. On the front top edge in front of the top framing spacers, a combustible wall (or drywall) may be brought up to the top edge of the unit. Refer to Figure 4.

PPRREE--IINNSSTTAALLLLAATTIIOONN IINNFFOORRMMAATTIIOONN

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.

Combustible wall or drywall to top front edge of unit

Figure 4: Mantel Clearance

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. Do NOT install appliance directly on carpeting, vinyl, or other soft floor covering. If the fireplace is to be installed on carpeting or tile, or on any combustible material other than wood flooring, the fireplace should be installed on a metal or wood panel that extends the full width and depth of the fireplace.

Minimum Vent Clearances to Combustible Materials:

The minimum clearances to combustibles for vent pipe require 3 inches at the top and 1 inch at the sides and bottom for horizontal sections of the vent system. Refer to the figure below. For wall or ceiling firestops and vertical sections of vent pipe a 1-inch minimum clearance all around the pipe must be maintained.

On some installation, if the distance between the first elbow and combustible material is three (3) inches, a heat shield is required. This part can be obtained from Monessen or constructed out of steel material to maintain halfinch (1/2”) air gap between the pipe and combustible material. The size of the part must be at least 12” wide by 12” long. Refer to figure below.
