Required Clearance to Combustibles
IMPORTANT
: “Combustibles” are defined as “normal construction materials” such as: wood framing materials, particle
board, mill board, plywood paneling, plywood sub-flooring and wood flooring.
The Maximus Linear Series Open Front
fireplaces and chimney systems are tested and listed for installation with “clearance
to combustibles” as follows:
•
Zero-inch (0”) clearance to the combustible floor; (Isokern Base Plate must be used)
•
Eight-inch (8”) clearance to combustible sheathing/ trim at opening top and sides.
•
Zero-inch (0”) clearance to combustible trim at the Isokern smoke dome front.
•
One- and one-half inches (1-1/2”) clearance at the sides of the Isokern firebox and smoke dome sides.
•
One-inch (1”) minimum air space to combustibles at all B-Vent double wall chimney components’ outer layer.
WARNING!!!
: When installing directly on carpet, tile, or other combustible material other than wood flooring, the appliance
should be installed on a metal or wood panel extending the full width and depth of the appliance.
IMPORTANT:
When installing on a combustible floor system the area in front of the fireplace must be covered with a non-
combustible hearth extension that is set tight against the fireplace front. The hearth extension shall extend at least twenty
inches (20”) beyond the finished front, and at least twelve inches (12”) beyond the finished sides of the fireplace opening.
CAUTION
: Maintain three inches (3”) clearance to insulation and vapor barriers from all firebox, smoke dome, and B-Vent
flue components.
EXCEPTION
: If insulation is used in walls surrounding the fireplace, insulation may be installed behind sheathing of gypsum
board, plywood, particle board, or other rigid fire rated material on the side facing the Isokern. The facing material cannot
be within 1-1/2” to the fireplace sidewalls.
NOTES:
1.
The fireplaces must sit upon a floor support designed to bear the total installed weight of the fireplace.
2.
All Maximus Linear installations will result in the minimum finished fire brick floor of the firebox being at least five-
and one-half inches (5-1/2”) above the combustible floor system.
Never place a Maximus Linear on a combustible
floor without the base plate!!!
