IMPORTANT: Vent-free gas log heaters add moisture to the air. Although this is beneficial, installing firebox in rooms without enough ventilation air may cause mildew to form from too much moisture. See Air for Combustion and Ventilation, page 6.

IMPORTANT: Make sure the firebox is level. If firebox is not level, log set will not work properly.

Note: Your Vanguard firebox is designed to be used in zero clearance installations. Wall or fram- ing material can be placed directly against any exterior surface on the rear, sides, or top of your firebox, except where standoff spacers are inte- grally attached. If standoff spacers are attached to your firebox, these spacers can be placed directly against wall or framing materials.

Use the dimensions shown for rough openings to create the easiest installation (see Built-In Firebox Installation, page 14).

Example

*Minimum 16 inches from Side Wall

Mantel Clearances for Built-In

Installation

If placing custom mantel above built-in firebox, you must meet the minimum allowable clearance between mantel shelf and top of firebox opening shown in Figure 8. These are the minimum allowable mantel clearances for a safe installation. Use larger clearances wherever possible to minimize the heating of objects and materials placed on the mantel.

INSTALLATION CLEARANCES

WARNING: Maintain the minimum clearances. If you can, provide greater clearances from floor, ceiling, and adjoining wall.

Carefully follow the instructions below. This will ensure safe installation.

Minimum Clearances For Side Combustible Material, Side Wall, and Ceiling

CAUTION: Close screens before operation of vent-free gas log heater. Do not allow the heater to touch or extend beyond the fireplace screen.

If your installation does not meet the minimum clearances in Figure 8, you must:

•raise the mantel to an acceptable height, OR • remove the mantel.

A.Clearances from the side of the fireplace cabinet to any combustible material and wall should follow diagram in Figure 6.

Example: The face of a mantel, bookshelf, etc. is made of combustible material and protrudes 3 1/2" from the wall. This combus- tible material must be 4" from the side of the fireplace opening (see Figure 6).

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