GV100W BOILER
INSTALLATION & OPERATING INSTRUCTIONS
The electrical connections to this boiler must be made in
accordance with all applicable local codes and the latest edition
of the National Electrical Code, ANSI/NFPA-70. Installation
should also conform with CSA C22.1 Canadian Electrical
Code Part I if installed in Canada. Install a separate 120 volt 15
amp circuit for the boiler. A shut-off switch should be located at
the boiler. The boilermust be grounded in accordance with the
authority having jurisdiction, or if none, the latest edition of the
National Electrical Code, ANSI/NFPA-70.
Line voltage field wiring of controls and other devices must
conform to the temperature limitation of type T wire at 95°F,
35°C
, above room temperature. Use copper conductors with a
minimum size of #14 awg. Low voltage wiring must not be less
than #18 awg with a neoprene, thermoplastic or other
equivalent insulation having a minimum insulation thickness of
0.012 in,
0.3 mm
.
THERMOSTAT INSTALLATION
Always follow the instructions included with the thermostat to
be used to control the boiler. Proper location of the thermostat
will ensure efficient trouble-free operation of the boiler. Mount
the thermostat to an inside wall at a height approximately five
feet above the floor. Avoid placing the thermostat in areas that
will not provide an accurate measurement of the room
temperature. Locating the thermostat behind a door, in an alcove,
close to a source of thermal radiation or in a drafty area will
cause poor or sporadic heating.
CO DETECTORS
WARNING: Installers must follow local regulations with
respect to the installation of CO detectors and follow
the manufacturer’s stated maintenance schedule for
this boiler!
ATTENTION: Observer les règlements règional à l'egard
des détecteurs de monoxyde de carbone et observer
entretien de manufacturier pour cette chaudière!
