22 Getting Started
Improper installation, adjustment, alteration, service or
maintenance can cause injury or property damage. For
assistance or additional information, consult a qualied
service technician, service agency or your dealer.
A. Design and Installation Considerations
WARNING! Risk of Fire or Explosion! Read all instruc-
tions before starting the installation
Gas inserts are designed for installations into solid fuel
masonry or UL127 listed factory built replaces. No ad-
ditional outside air source is required.
Installation MUST comply with local, regional, state and na-
tional codes and regulations. Consult insurance carrier, local
building inspector, re ofcials or authorities having jurisdic-
tion over restrictions, installation inspection and permits.
Prior to installing the gas insert:
• Ensure chimney is constructed of non-combustible
materials.
• Ensure chimney is clean and in good working order.
• Ensure that all chimney cleanouts t properly to prevent
air leakage into chimney.
• Ensure combustible mantel and surround clearances
comply with insert requirements.
• Ensure all joints are properly engaged and the chimney
is properly secured.
• Determine minimum replace size. See Section 3.A and
3.B.
• Determine gas supply piping requirements.
• Determine electrical wiring requirements.
• Determine nishing details.
• Determine whether optional accessories—devices such
as a wall switch or remote control—are desired.
Installation and service of this appliance should be performed by
qualied personnel. Hearth & Home Technologies recommends
HHT Factory Trained or NFI certied professionals.
