3.0 INSTALLATION PLANNING
3.1 Fireplace Placement
Clearance Requirements
WARNING: Follow all instructions and clearances as outlined
throughout this manual.
• Location of doors and windows on all oors of the home in
relation to the replace and chimney must be considered and be
in compliance with applicable codes, if any.
• This replace must be installed on a level surface capable of
supporting the replace and venting.
• The replace must be placed directly on wood or non-
combustible surface (not linoleum or carpet) extending the
entire depth and width of the replace.
• Metal sealing strips must be used under the replace and hearth
extension. See 3.4 Hearth Extension on page 13 for more
information.
• Due to high surface temperatures, the replace should be
located out of trac and away from furniture and draperies.
• The minimum hearth extension oor area is 16” (406 mm) in
front of the replace opening and 8” (203mm) beyond each
side of the replace opening. The minimum hearth extension
must be insulated with non-combustible oor protection with a
minimum insulation R-value of 0.8.
Manufactured hearth materials have a published R value
(resistance to heat) or k value (conductivity of heat). Use the
following formula to convert a k value to a R value.
R=1/k x inches of thickness. See 3.5 Alternate Floor Protection
Material on page 14 for full equation.
• Please be aware of the large amount of heat this replace will
produce when determining a location.
