C. Constructing the Appliance Chase
To further prevent drafts, the wall shield and ceiling firestops should be caulked with caulk with a minimum of
300ºF continuous exposure rating to seal gaps. Gas
line holes and other openings should be caulked with
caulk with a minimum of 300ºF continuous exposure rating
or stuffed with unfaced insulation. If the appliance is being
installed on a cement surface, a layer of plywood may be
placed underneath to prevent conducting cold up into the
room.
NOTICE: Install appliance on hard metal or wood surfaces
extending full width and depth. DO NOT install directly
on carpeting, vinyl, tile or any combustible material other
than wood.
A chase is a vertical box-like structure built to enclose the
gas appliance and/or its vent system. In cooler climates
the vent should be enclosed inside the chase.
NOTICE: Treatment of ceiling firestops and wall shield
firestops and construction of the chase may vary with the
type of building. These instructions are not substitutes
for the requirements of local building codes. Therefore,
you MUST check local building codes to determine the
requirements to these steps.
Chases should be constructed in the manner of all outside walls of the home to prevent cold air drafting problems. The chase should not break the outside building
envelope in any manner.
WARNING! Risk of Fire! Maintain specified air space
clearances to appliance and vent pipe:
Walls, ceiling, base plate and cantilever floor of the chase
should be insulated. Vapor and air infiltration barriers
should be installed in the chase as per regional codes for
the rest of the home. Additionally, in regions where cold
air infiltration may be an issue, the inside surfaces may be
sheetrocked and taped for maximum air tightness.
• Insulation and other materials must be secured to prevent
accidental contact.
• The chase must be properly blocked to prevent blown
insulation or other combustibles from entering and
making contact with fireplace or chimney.
• Failure to maintain airspace may cause overheating and
a fire.

D. Hearth Extension
WARNING! Risk of Fire! Non-combustible hearth extension may be required when appliance is installed on combustible surface.
•
Hearth extension must be non-combustible and
serves to protect combustible floors in front of appliance. See Figure 3.10 and Figure 3.11.
•
The base of the fireplace may sit on a combustible
surface. See Figure 3.11. The area in front of the
appliance must be protected by a non-combustible
hearth extension, unless the appliance is raised a
minimum of three inches above the combustible floor
or hearth. See Figure 3.11 and Figure 3.12.
•
If a hearth greater than one inch in thickness is desired, the appliance must be raised by the equivalent
height to ensure that the hearth extension does not
interfere with the installation of the glass assembly
required for fireplace operation. See Figure 3.11.
NOTICE: DO NOT install a hearth that is greater than
one inch thick. Hearth will interfere with installation of
glass assembly. Total hearth height must not exceed one
inch from bottom of appliance when appliance is installed

Ember material is shipped with this gas appliance. To place
the ember material:
• Embers CANNOT be placed directly over ports. Care
should be taken not to cover the lighting trail of ports
(from back to front).
• Place dime-size pieces of Glowing Embers® just in front
of the port trail, but not on or in between the ports (see
Figure 11.10). Care should be taken so that the ports are
not covered. Failure to follow this procedure will likely
cause lighting and sooting problems.
• Save the remaining ember materials for use during
appliance servicing. The embers provided should be
enough for 3 to 5 applications.
D. Lava Rock and Mystic Ember Placement
1. Apply the lava rock and Mystic Embers as shown in
Figure 11.9. The lava rock and Mystic Embers are
to be placed around the base hearth refractory and
can be used to conceal the joints of the hearth base
refractory pieces.
