GENERAL INSTALLATION INFORMATION
Pilot
-
The gas log heater is fitted with a specially designed safety pilot light which senses the
amount of oxygen available in the room and shuts the gas log heater off if the oxygen
level begins to drop below a satisfactory level. The pilot can only be relit when adequate
fresh air is available.
Thermal
Generator
- The millivolt gas log pilot is fitted with a millivolt generator to provide power for re-
mote activation.

This heater shall not be installed in a confined space or unusually tight construction unless provisions
are provided for adequate combustion and ventilation air.
The National Fuel Gas Code ANSI Z223.1 defines a confined space as a space whose volume is less
than 50 cubic feet per 1,000 Btu per hour (4.8m
3
per kw) of the aggregate input rating of all appliances
installed in that space and an unconfined space as a space whose volume is not less than 50 cubic feet
per 1,000 Btu per hour (4.8 m
3
per kw) of the aggregate input rating of all appliances installed in that
space. Rooms communicating directly with the space in which the appliances are installed, through
openings not furnished with doors, are considered a part of the unconfined space.
Unusually tight construction is defined as construction where:
a) Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with
a rating of 1 perm (6 x 10
-11
kg per-pa-sec-m
2
) or less with openings gasketed or sealed, and
b) Weather stripping has been added on openable windows and doors, and
c) Caulking or sealant are applied to areas such as joints around windows and door frames, between
sole plates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumb-
ing, electrical, and gas lines, and at other openings.
