SAFETY DEVICE
A standard requirement for all vent-free room
heaters, this heater has a pilot with an Oxygen
Depletion Sensor(ODS) safety shutoff system.
The ODS/pilot shuts off the heater if there is
not enough fresh air.
PIEZO IGNITION SYSTEM
This heater is equipped with a piezo ignitor.
This system requires no matches, batteries, or
other sources to light heater.
THERMOSTATIC HEAT
CONTROL ON THERMOSTAT
MODELS
These heaters have a control valve with a
thermostat sensing bulb. This results in the
greatest heater comfort and may result in
lower gas bills.
WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combustion. An
unvented room heater produces approximately one (1)
ounce (30ml) of water for every 1,000 BTU's (.3KW's) of
gas input per hour.
Unvented room heaters are recommended as supplemental
heat (a room) rather than a primary heat source (an entire
house). In most supplemental heat applications, the water
vapor does not create a problem. In most applications,
the water vapor enhances the low humidity atmosphere
experience during cold weather.
