Combustibles may not extend to unit face.

Do not notch wallboard around standoffs.

The R90 may be placed on or near construction materials. The combustion air kit, fi re stop spacer and roof fl ashings (not chase

flashings) may be placed directly on or against normal construction materials. The chimney requires a minimum 2" (51mm) clearance. A combustible mantle (to a depth of 10", 254mm) may be installed no closer than 18" (457mm) above the warm air vent or 55-1/2" (1410mm) from bottom of unit.

The chimney must be enclosed when installed in or passing through a living area where combustible material or people may come in contact with it. This is important to prevent possible personal injury or fi re hazard.

For any further information, please call your dealer. Special restrictions apply to the front and facing of the fi replace and nearby walls.

WARNING: If insulation is used, do not place the unit against it. Insulation or vapor barriers, if used, must be secured to assure insulation and vapor barriers remain in place and do not affect the required air spaces.

WARNING: Do not pack or fi ll required air spaces with insulation or other material. No material of any kind is allowed in these areas.

NOTES:

1)Do not insulate the chase cavity with blown or fi ll type insulation materials.

2)Local codes may not require a firestop at the ceiling level for outside chase installations; however, it is recommended for safety and the reduction of heat loss.

3)We recommend that you insulate at least the first floor of the chase to prevent heat loss.

4)Some local codes require 1 hour fi re rating on one or all sides of fi re chases. Check with your local authorities.

NOTES:

1)Minimum Chase sizes must be met according to the framing directions (page 149). US Installations will require a minimum ventilation with one 30 sq. in. (194 sq. cm.) opening grill (air is drawn from within the home not outside).

2)Mantel min. Height of 18” (457mm) from top of louver opening to underneath mantel or 55 1/2” (1410mm) from bottom of unit.

3)Minimum non-combustible facing must be installed according to the table on this page. Finishing material to be installed on top of this.

4)Framing is slightly larger than unit dimensions to allow for easier installation (50 3/4”, 1289mm h x 44”, 1118mm w)

5)Must maintain a min. of 46” (1168mm) from top of louver opening to fi nished ceiling.

6)Sidewall clearances, as detailed on this page, must be maintained according to your location.

7)Hearth must be a min. 40” (1016mm) wide x 18” (457mm) deep and 1/2” (127mm) thick.
