A. Design and Installation Considerations
Heat & Glo direct vent gas appliances are designed to op-
erate 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 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 appli-
ance, the same as you would for locating exterior win-
dows 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.
