U.L. Listed gas appliances are tested and approved without
requiring changes for elevations from 0 to 2000 feet in the
U.S.A. and Canada.
When installing this appliance at an elevation above 2000
feet, it may be necessary to decrease the input rating by
changing the existing burner orifice to a smaller size. Input
rate should be reduced by 4% for each 1000 feet above a
2000 foot elevation in the U.S.A., or 10% for elevations
between 2000 and 4500 feet in Canada. If the heating value
of the gas has been reduced, these rules do not apply . To
identify the proper orifice size, check with local gas utility .
If installing this appliance at an elevation above 4500 feet
(in Canada), check with local authorities.
W ARNING
Do NOT use this appliance if any part has been under
water. Immediately call a qualified service technician to

Getting Started
A. Design and Installation Considerations
Heat & Glo 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 T wilight-II has been carefully engineered to provide a
unique fireplace 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 flashing and sealing
instructions.
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 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.
B. Tools and Supplies Needed
Before beginning the installation be sure that the following
tools and building supplies are available.
Reciprocating saw Framing material
Pliers Hi temp caulking material
Hammer Gloves
Phillips screwdriver Framing square

structure meet.
• Place a generous bead of silicone caulk into the corner
of the protective hearth strip.
• Place the metal strip onto the structure where the outer
edge of the appliance will sit (see Figure 5.1).
• Place the appliance into position. Make sure flashing
edges on the outdoor surround fit up tight to the framing.
The diagram shows how to properly position, level, and secure the appliance (see Figure 5.2). Nailing tabs are provided to secure the appliance to the framing members.
• Place the appliance into position.
• Level the appliance from side to side and front to back.
• Shim the appliance with non-combustible material, such
as sheet metal, as necessary.
• Bend out nailing tabs on each side.
• Keep nailing tabs flush with the framing.
• Secure the appliance to the framing by using nails or
screws through the nailing tabs.

being installed is compatible with the available gas type.
Any natural or propane gas conversions necessary to meet
the appliance and locality needs must be made by a qualified technician using Hearth & Home Technologies specified and listed gas conversion kit.
B. Gas Pressures
Proper input pressures are required for optimum appliance
performance. Gas line sizing requirements need to be made
following NFP A51.
WARNING
Fire Risk.
Explosion Hazard.
High pressure will damage valve.
• Disconnect gas supply piping BEFORE
pressure testing gas line at test pressures
above 1/2 psig.
• Close the manual shutoff valve BEFORE
pressure testing gas line at test pressures
equal to or less than 1/2 psig.
C. Gas Connection
NOTE: Have the gas supply line installed in accordance
with local building codes, if any. If not, follow ANSI 223.1.
Installation should be done by a qualified installer approved
and/or licensed as required by the locality. (In the
