General Information
1.0 Introduction
Thank you and congratulations for choosing the Archgard I.H.E.A.T. Advantage.
The I.H.E.A.T. Advantage allows you to distribute heat from your Archgard fireplace to wherever you need it the most. It is solidly
designed using the latest technology and manufactured to the highest quality. It is our aim to provide you with a heating experience that
brings many trouble-free years of reliable service.
Some of the many features of your I.H.E.A.T. Advantage are:
• Versatility Direct the heat from your fireplace to where you need it the most with multiple configuration options
• Television orArt Installation This kit reduces the amount of heat directly above the fireplace. This allows heat sensitive objects
such as electronics or decor to be placed above the fireplace (see Section 9.2). It also allows a
lower mantel installation (see Section 9.1)
• Styling Options Many possible finishes to match any decor

8.0 I.H.E.A.T. Framing
IMPORTANT
Framing dimensions should allow for wall covering thickness and fireplace facing materials. If using a hearth, adjust rough opening
size as necessary to maintain at least minimum clearance requirements. Non–combustible facing material may be applied over (but
not directly to) fireplace face. This will prevent facing material from falling offdue to heat expansion.
Do not obstruct the flow of ventilation air.
WARNING
Provide adequate clearances around air openings into the combustion chamber. Do not obstruct upper and lower grill openings.
Room air enters through lower passage, is heated and exists through upper passage. Blocking these passages may result in
overheating, creating a potentially hazardous situation.
The layout of the framing differs from the Installation,
Operation, and Maintenance Manual included with the
fireplace to accommodate the ducting used when installing
I.H.E.A.T.
Determine exact position of your fireplace, including hearth
height, width, and depth (if applicable). If possible, place
fireplace in such a manner that vent termination will be
between two studs, eliminating the need for additional
framing.
Consider height of hearth finish material (stone, brick etc.)
when building fireplace platform.
Install fireplace on hard metal or wood surface extending
the full width and depth of fireplace.
If masonry is to be used (optional), prepare the necessary
foundation for the masonry load. When masonry
construction is used, a lintel iron must be used over top
of fireplace to support the added weight. Never use this
fireplace to support additional weight.
Build hearth to desired size and height. If a hearth
extension is desired, combustible material may be used.
See the Installation, Operation, and Maintenance Manual
included with the fireplace.

9.2 Installing a TV or hanging Artwork
WARNING
Most television manufacturers instruct the homeowner to never place a television above a heat source.
Placing heat sensitive objects such as televisions or artwork above a heat source may affect the longevity of the item and negate any
warranty the item may have. If you do place heat sensitive objects above the fireplace, please be aware of the large amount of heat
generated by the fireplace. We recommend placing the item above a mantel to reduce the amount of heat that can reach the object.
Archgard Industries does not take responsibility for any negative impact to objects placed near the fireplace.
WARNING
Never install objects over the face of the fireplace. Always maintain a 14.02" clearance from the top of the fireplace opening. Be sure
to protect any wires, cables, and other heat sensitive components from hot objects including the fireplace, ducting, discharge heads,
and venting.
