IMPORTANT INFORMATION
Do not use this appliance if any part has been submerged under water. Immediately call a qualified service
technician to inspect the appliance and to replace any part of the control system and any gas control which has
been under water.
This heater shall not be installed in a confined space unless provisions are provided for adequate combustion
and ventilation air. The National Fuel Gas Code defines a confined space as a space whose volume is less
than 50 cubic feet per 1,000 BTU per hour (4.8m3 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 that 50 cubic feet per
1,000 BTU per hour (4.8m3 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
WARNING: If the area in which the heater may be operated is smaller than that defined as an
unconfined space provide adequate combustion and ventilation air by one of the methods
described in the National Fuel Gas Code, ANSI z223.1, 1992, Section 5.3
WARNING: Before installing in a solid fuel burning fireplace, the chimney flue and firebox must be
cleaned of soot, creosote, ashes and loose paint by a qualified chimney cleaner.
This appliance is equipped with an ODS (oxygen depletion sensor) pilot light safety system that turns off the
appliance if enough fresh air is not available. Additional ventilation is obtained by opening a door to another
room or opening a window.
Always ensure that there is proper ventilation from the area the system is operating in.
Any outside air ducts and/or ash dumps in the fireplace shall be permanently closed at time of
appliance installation.
This appliance must be used with glass doors in the OPEN position.
A fireplace screen with an opening for combustion air must be in place when the appliance is operating, unless
other provisions for combustion air are provided.
IMPORTANT: During the manufacturing process this appliance is treated with certain coloring agents. These
agents are not harmful, but may produce annoying smoke and smell as they are burned off. This
is a temporary occurrence that ceases after 4 to 6 hours of use. During the “burning off” period,
provide ventilation by opening windows, doors and the chimney flue to allow odors to dissipate.
Any remaining odors will burn off with continued use.
