service technician to inspect the appliance and to replace any part of the control system and

any gas control which has been under water.

LOCATING GAS FIREPLACE

See ALLOWABLE TERMINATION LOCATIONS.

The fireplace may be installed in any location that maintains proper clearances to combustibles,

air conditioning ducts, electrical wiring and plumbing. Select a location that is accessible for

venting See section Allowable Termination Locations listed in this manual. When the appliance

is installed directly on carpeting, vinyl tile or other combustible materials, other than wood

flooring, the appliance must be installed on metal or wood panel extending the full width and

depth of the appliance.

GAS CONNECTIONS

Have your gas supplier or a qualified gas fitter run a gas supply line into the fireplace. The line

must be properly sized and fitted according to the installation codes. Immediately upstream of the

supply connection, the fitter shall provide an accessible manual shut-off valve and a 1/8 NPT

plugged tapping accessible for connection to a test gauge.

CAUTION: The appliance and its individual 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 (3.5 kPa). 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 piping system at test

pressures equal to or less than 1/2 psig (3.5 kPa). Failure to do so will damage the appliance’s gas

valve. Such damage is not covered by the manufacturer’s warranty.
