Clearances to Combustibles
The distance to be maintained from the surfaces of the
fireplace to combustibles must be observed. Below is a list
of the most common combustible materials to name a few:
Drywall Wood flooring Plywood
Sub-flooring Wood Framing Particle board
Mill board Plywood paneling
Maintain the following clearances:
•
Unit sides, rear, Dome sides, rear & top: 2” (51 mm)
•
Combustible Floors: 8” (203 mm)
•
Combustible Sheathing above opening top: 18” (203 mm)
•
Sheathing or trim to opening sides: 8” (203 mm)
•
Mantel above opening: (see fig. below)
•
Opening to sidewall: 24” (609 mm)
•
Hearth extension beyond front: 20” (508 mm)
•
Hearth extension beyond sides: 12” (305 mm)
•
Insulation from firebox: 2” (51 mm)
Understanding Clearance to Combustibles
There is a build-up of a considerable amount of radiant
heat on the outer surfaces of the Mason-Lite Fireplace. It’s
critical that proper clearances to combustibles be
maintained so that this radiant heat is maintained to safe
limits.
Combustible Floor Clearances
These Mason-Lite Fireplaces have been designed with
clearance to combustible floors as indicated in Page 18.
Cover any part of the combustible floor system left
exposed with 1” (one inch) thick ceramic fiber insulation
rated up to 2,100° F.
Attention : It is critical to abide by the clearances listed
in this manual for all components specified as it allows for
movement of hot air from the fireplace into interior areas of
the chimney chase. Also, be certain that the chimney
system be installed as stated below.
Prior to starting the
installation, check with local, regional or state codes for any
restrictions or required permits regarding your fireplace
installation.
Mason-Lite Fireplace &Chimney System
1) The Mason-Lite is designed to be installed with a listed
UL103 - Class A, Metal Chimney System.
2) This Mason-Lite fireplace is intended as a supplemental
heat source only. It is not intended as a primary heat
source.
3) It is the responsibility of the contractor installer (not the
manufacturer) to ensure that adequate combustion air
is provided for proper function of this fireplace.
Fireplaces take up a large volume of replacement air
from outside the house and if the house is of airtight
construction, smoke spillage may occur if proper draft is
not achieved.
4) There are many conditions beyond the manufacturer’s
control regarding improper fireplace operation. The
manufacturer cannot ensure “smoke free” operation,
nor can the manufacturer take on the responsibility for
problems with surrounding construction; chimneys that
have not been built at the correct heights; system drafts
caused by faulty mechanical systems; adverse weather
conditions or any other environmental situations over
which the manufacturer has no control.
5) Inspect all fireplace & chimney components for
evidence of damage prior to starting installation.
Consult your local distributor for replacement parts if
necessary.
6) Under no circumstances should you make any
adjustments or modifications to the chimney system
during the installation procedure. If you do, you are not
only liable for negating the warranty, but you could very
well cause a serious malfunction of the fireplace. You
must follow these chimney instructions.
7) Caution is urged if it is decided to add insulation
material to any part of the Mason-Lite Fireplace or
Chimney system, be certain that the insulation material
is kept at least 2” (two inches) away from any part of
the system. When using insulation or vapor barrier
materials, cover with a layer of plywood, particle board
or gypsum board to maintain the specified 2” (two inch)
clearance.
8. Air spaces around firebox must remain open. DO NOT
fill these open spaces with insulation or packing
material of any kind.
Chimney System Heights
When installed, the maximum overall height of the
chimney system from bottom of fireplace to the
top/termination chimney is 40 feet. The
minimum installed
height of the completed Chimney System is 14 feet with a
straight flue stack, 17 feet if the chimney includes one or
two offset sections.
