Getting Started
A. Design and Installation Considerations
Hearth & Home Technologies direct vent gas appliances
are designed to operate with all combustion air siphoned
from outside of the building and all exhaust gases expelled
to the outside. No additional outside air source is required.
The TWILIGHT-II-MOD has been carefully engineered to
provide a unique fi replace experience. Since it is different
than any other product on the market, care must be taken
when installing this appliance so that our customer does
not experience undesirable performance or conditions.
1. Install the appliance according to this Owner’s Guide
paying particular attention to fl ashing and sealing in-
structions.
2. In the cold northern climates pay attention to exposures and prevailing wind conditions when locating the
appliance, the same as you would for locating exterior
windows and doors.
The TWILIGHT-II-MOD has the thermal characteristics of a
high quality window system. Temperatures near the appliance will be cooler than what is realized with a fully insulated
wall.
Operation of the appliance will eliminate any cool drafts
and will provide the room with a comfortable ambiance.
Installation MUST comply with local, regional, state and
national codes and regulations. Consult insurance carrier,
local building inspector, fi re offi cials or authorities having
jurisdiction over restrictions, installation inspection and
permits.
Before installing, determine the following:
• Where the appliance is to be installed.
• Gas supply piping requirements.
• Electrical wiring requirements.
• Framing and fi nishing details.
• Whether optional accessories—devices such as a fan,
wall switch, or remote control—are desired.
Installation and service of this appliance should be
performed by qualifi ed personnel. Hearth & Home
Technologies suggests NFI certifi ed or factory
trained professionals, or technicians supervised by
an NFI certifi ed professional (www.nfi certifi ed.org).
Improper installation, adjustment, alteration, service or
maintenance can cause injury or property damage. For
assistance or additional information, consult a qualifi ed
service technician, service agency or your dealer.
Outdoor Lifestyles by Hearth & Home Technologies • Installation Manual TWILIGHT-II-MOD • 2290-970 Rev. F • 11/13
B. Tools and Supplies Needed
Before beginning the installation be sure that the following
tools and building supplies are available.
Tape measure Framing material
Pliers High temperature caulking material
Hammer Phillips screwdriver
Gloves Framing square
Voltmeter Electric drill and bits (1/4 in.)
Plumb line Safety glasses
Level Reciprocating saw
Manometer Flat blade screwdriver
Non-corrosive leak check solution
1/2 - 3/4 in. length, #6 or #8 Self-drilling screws
One 1/4 in. female connection (for optional fan).
C. Inspect Appliance and Components
• Carefully remove the appliance and components from
the packaging.
• The decorative doors and fronts may be shipped in
separate packages.
• Report to your dealer any parts damaged in shipment,
particularly the condition of the glass.
• Read all of the instructions before starting the instal-
lation. Follow these instructions carefully during the
installation to ensure maximum safety and benefi t.
WARNING! Risk of Fire or Explosion! Damaged parts
could impair safe operation. DO NOT install damaged, in-
complete or substitute components. Keep appliance dry.
Hearth & Home Technologies disclaims any responsibility for,
and the warranty will be voided by, the following actions:
• Installation and use of any damaged appliance or vent
system component.
• Modifi cation of the appliance or vent system.
• Installation other than as instructed by Hearth & Home
Technologies.
• Improper positioning of the gas logs or the glass door.
• Installation and/or use of any component part not approved
by Hearth & Home Technologies.
Any such action may cause a fi re hazard.
WARNING! Risk of Fire, Explosion or Electric Shock!
DO NOT use this appliance if any part has been under
water. Call a qualifi ed service technician to inspect the
appliance and to replace any part of the control system
and/or gas control which has been under water.
