Isokern Maximus Linear Series Gas Fireplace
Flush Wall Finish Detail
Maximus Linear units are designed to be installed so that the
rough front face of the Isokern firebox and smoke dome sit flush
to the room face of the rough framing members that create the
room wall finish.
(Figure 30)
IMPORTANT:
Do not build a combustible frame wall in front of the
Maximus Linear firebox!
(Figure 31)
Clearance to Drywall:
Drywall can be placed directly in contact with the front of
the Maximus Linear smoke dome. With the Isokern firebox/smoke
dome set flush with the interior face of wall framing, drywall can
be hung on the framing members and pass across the face of the
Maximus Linear smoke dome and in contact with it.
Combustible wood sheathing such as plywood and particle
board may be used to cover the front of the Isokern smoke dome
and be in direct contact with it. Application of such combustible
sheathings must assure that the sheathing is held a minimum of
eight inches (8”) away from each side of the finished fireplace
opening and a minimum of eight inches (8”) inches above the top
of the finished fireplace opening.
(Figure 30 & 31)
If combustible wood sheathing is installed across the face
of the Isokern smoke dome front be sure that when the required
noncombustible finished facing materials are applied directly to
the front of the Maximus Linear, that no gaps or voids are left
behind the finished facing materials. Completely seal the required
noncombustible finished facing materials directly to the Isokern
unit with Earthcore Adhesive or other non-combustible grout.
IMPORTANT:
Since there is no fire brick set along the top
of the Maximus Linear firebox opening, when setting the
noncombustible facing material onto the drywall across the top
of the firebox opening there will be a gap between the back of
the noncombustible finish material and the rough front face of the
Isokern Smoke Dome.
Be sure to fill this gap with Earthcore Adhesive in conjunction
with placement of the code required noncombustible finish
facing material that is set across the top of the firebox opening.
WARNING:
Avoid false chimneys.
IMPORTANT:
Failure to seal any gaps between the front face of
the Maximus Linear and the back of the noncombustible finished
facing material will create what is known as a “false chimney” or
“secondary chimney”. A “false chimney”, in this case is the narrow
gap (mentioned above) between the back of the noncombustible
facing material at the top of the firebox opening and the rough
front of the Maximus Linear smoke dome. If left unfilled this
gap creates a “false chimney” which can cause a fire hazard by
drawing considerable heat out of the firebox and into the space
behind the noncombustible finish facing and from there up into
the wall cavity behind the drywall or other sheathing material that
houses the Isokern fireplace.
