Installation and Clearences for Vent-free Operation (cont.)

INSTALLATION

Continued

Care fully follow the instructions below. This will ensure safe installation into masonary, UL127-listaed manufactured ﬁreplace, or listed vent-free ﬁrebox.

Minimum Clearances For Side Combustible material, side wall, and ceiling

A. Clearances from the side of the ﬁreplace cabinet to any combustible material and wall should follow diagram in ﬁgure 4.

Example: The face of a mantel, bookshelf, etc.. is made of combus- tible material must be 4" from the side of the ﬁreplace to the cabinet (see ﬁgure 4).

B. Clearances from the top of the ﬁreplace opening to the ceiling should not be less than 42 inches.

Example

*Minimum 16 inches from Side Wall

Figure 4 - Minimum Clearance for Combustible to Wall

NOTICE: Non thermostat controlled heaters maybe used as a vented product. If so, you must always run heater with chimney ﬂue damper open, noncombustible material above the ﬁreplace opening is not needed. Go to Installing Damper Clamp Accessory for vented operation.

Minimum Noncombustible material Clearences

If Not Using Mantel

Note: If using a mantel proceed to If Using Mantel. If not using mantel, follow the information on this page.

You must have non-combustible material(s) above the ﬁreplace opening. Non-combustible materials (such as slate, marble, tile, etc..) Must be at least 1/2 inch thick. With sheet metal, you must have non-combustible material behind it. Non-combustible material must extend at least 8" up (for all models). If non-combustible material is less than 12", you must install the ﬁreplace hood accessory (24" and 30" Models Only). See Figure 5 for minimum clearances.

If Using Mantel

You must have non-combustible material(s) above the ﬁreplace opening. Non-combustible materials (such as slate, marble, tile, etc.) must be at least 1/2 inch thick. With sheet metal, you must have non-combustible material behind it. Non-combustible material must extend at least 8 inches up (for all models). If non-combustible material is less than 12", you must install the ﬁreplace hood accessory (24" Models Only). Even if non-combustible material is more than 12", you may need the hood accessory to deﬂect heat away from your mantel shelf. See Figure 5 and Figures 6 and 7, page 9, for minimum clearances.

IMPORTANT: If you cannot meet these minimum clearances, you must operate heater with chimney ﬂue damper open. Go to Installing Damper Clamp Accessory for Vented Operation, page 10.

Noncombustible	Requirements for
Material Distance (A)	Safe Installation
12" or more	Non-combustible material OK.
Between 8" and 12"	24" Models: Install ﬁreplace hood acces-
	sory (GA6060, see Accessories, page
	27).
	18" Model: Non-combustible material
	OK.
Less than 8"	Non-combustible material must be extend-
	ed to at least 8". See Between 8" and 12",
	above. If you cannot extend material, you
	must operate heater with ﬂue damper
	open.
