Noncombus-

tible Material

Distance (A)

Requirements for Safe

Installation

12" or more Noncombustible material

okay.

Between 8"

and 12"

24" Models: Install fireplace

hood accessory (GA6050 or

GA6053 see Accessories,

page 30).

18" Model: Noncombustible

material okay.

Less than 8" Noncombustible material

must be extended to at least

8". See Between 8" and 12",

above. If you cannot extend

material, you must operate

heater with flue damper open.

MANTEL CLEARANCES

In addition to meeting noncombustible mate-

rial clearances, you must also meet required

clearances between fireplace opening and

mantel shelf. If you do not meet the clearances

in Figure 6, page 11 you will need a hood.
Determining Minimum Mantel Clearance

If you meet minimum clearance between man-

tel shelf and top of fireplace opening, a hood

is not required (see Figure 6, page 11).
Determining Minimum Mantel Clearance

When Using a Hood

If minimum clearances in Figure 6 are not

met, you must have a hood. When using a

hood there are still certain minimum mantel

clearances required. Follow minimum clear-

ances shown in Figure 7, page 11 when

using hood.

Marble, Tile, etc.) Above Fireplace

NOTICE: Manual control heaters

may be used as a vented product.

If so, you must always run heater

with chimney flue damper open.

If running heater with damper

open, noncombustible material

above fireplace opening is not

needed. Go to Installing Damper

Clamp Accessory for Vented

Operation, page 12.

Minimum Noncombustible Material

Clearances

If Not Using Mantel

Note: If using a mantel, proceed to If Using

Mantel. If not using a mantel, follow the infor-

mation below.
You must have noncombustible material(s)

above the fireplace opening. Noncombustible

materials (such as slate, marble, tile, etc.) must

be at least 1/2" thick. With sheet metal, you

must have noncombustible material behind

it. Noncombustible material must extend at

least 8" up. If noncombustible material is less

than 12", you must install the fireplace hood

accessory (24" models only). See Figure 5 for

minimum clearances.

If Using Mantel

You must have noncombustible material(s)

above the fireplace opening. Noncombustible

materials (such as slate, marble, tile, etc.) must

be at least 1/2" thick. With sheet metal, you

must have noncombustible material behind it.

Noncombustible material must extend at least

8" up. If noncombustible material is less than

12", you must install the fireplace hood acces-

sory (24" models only). Even if noncombustible

material is more than 12", you may need the

hood accessory to deflect heat away from your

mantel shelf. See Figure 5 and Figure 6 and 7

on page 11 for minimum clearances.
