• This appliance must be installed only in a solid-fuel burning (woodburning) fireplace with a working flue and
constructed of noncombustible materials.
• The appliance area must be kept clear and free from combustible materials, gasoline and other flammable
vapors and liquids.
• A fireplace screen must be in place when the log set is burning and, unless other provisions for combustion
air are provided, the screen shall have an opening(s) for introduction of combustion air.
• Installation and the provisions for combustion and ventilation air must conform with the latest edition of the
national Fuel gas code ansI Z223.1
or in Canada, the current
can/cga-B149.1 and B149.2.
• Inlet and outlet taps are provided on the gas control (M Series) for a test gauge connection. Replace the plug
after the test.
• The appliance and its manual shutoff valve must be disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in excess of 1/2 PSIG.
• The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff
valve during any pressure testing of the gas supply pipe system at test pressure equal to or less than 1/2
PSIG.
• The minimum size fireplace in which the log set can be installed and the minimum permanent free opening
that must be provided by either the fireplace chimney or chimney damper to vent the flue gases must be in
accordance with the tables in Figure 1.
• Any chimney damper must be fixed so that the minimum permanent vent opening will be maintained at all
times (by screw, bolt at damper edge, or hole in damper.)
• Solid fuel shall not be burned in a fireplace where a decorative gas appliance is installed.
1. high altitude Installation
For U.S. installation, appliances are tested and approved for elevations from 0-2000 feet. When installing this Imperial
Gas Log Set at an elevation above 2000 feet, National Fuel Gas Codes require a decrease of the input rating by changing
the existing burner orifice to a smaller size. Input should be reduced 4% for each 1000 feet above sea level. Check with
the local gas utility for proper orifice size identification. The current orifice is available from your Heatilator distributor.
For Canada, appliances are certified for elevations from 0-4500 feet. When installing this Imperial Gas Log Set at an
elevation between 0-4500 feet in Canada, the input rating does not need to be reduced. When installing this log set at an
elevation above 4500 feet in Canada, check with local authorities.
