General Information - Lennox EVB125 Installation Instructions Manual

This appliance uses a millivolt type control
system consisting of a gas control valve with
regulator (control to adjust for fl ame appear-
ance and heat output), a standing pilot burner
assembly, a thermopile, thermocouple, a
piezo igniter, and ON/OFF switch. All exhaust
gases must be vented outside the structure.
Combustion air is drawn from the room where
appliance is installed. THE GAS BURNER
SYSTEM ON THIS APPLIANCE DOES NOT
REQUIRE 120 VOLT POWER TO OPERATE.
However, the heat circulation blower requires
120 Volt power (the appliance can be safely
used with the blower turned off). The blower
operation is controlled by a variable speed
rheostat located on the left side surround
panel (if optional surround is installed)
and temperature switch located beneath of
fi rebox bottom on the front left side.

GENERAL INFORMATION

The appliance installation, repair and annual
inspection should be performed by a quali-
fi ed service person. It is imperative that the
control compartment, burners and circulat-
ing air passage ways of the appliance be
kept clean.
S'assurer que le brùleur et le compartiment
des commandes sont propres. Voir les
instructions d'installation et d'utilisation qui
accompagnent l'appareil.
Provide adequate clearances and adequate
accessibility clearance for service and proper
operation.

This appliance must be isolated from the
gas supply piping system (by closing it's
individual manual shut-off 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).
This appliance and it's individual shut-off
valve must be disconnected from the gas
supply piping system during any pressure
testing of that system at pressures greater
than 1/2 psig (3.5 kPa).
