CARBON MONOXIDE POISONING: EARLY
SIGNS OF CARBON MONOXIDE POISONING
ARE SIMILAR TO THE FLU WITH HEADACHES,
DIZZINESS AND/OR NAUSEA. IF YOU HAVE
THESE SIGNS, OBTAIN FRESH AIR IMMEDI-
ATELY. TURN OFF THE GAS SUPPLY TO THE
APPLIANCE AND HAVE IT SERVICED BY A
QUALIFIED PROFESSIONAL, AS IT MAY NOT
BE OPERATING CORRECTLY.
Do not use these appliances if any part has
been under water. Immediately call a qualifi ed,
professional service technician to inspect
the appliance and to replace any parts of the
control system and any gas controls which
have been under water.
Ne pas se servir de cet appareil s'il a été
plongé dans l'eau, complètement ou en
partie. Appeler un technicien qualifi é pour
inspecter l'appareil et remplacer toute partie
du système de contrôle et toute commande
qui ont été plongés dans l'leau.
Test gage connections are provided on
the front of the millivolt gas control valve
(identifi ed IN for the inlet and OUT for the
manifold side).
These appliances must be isolated from the
gas supply piping system (by closing their
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).
These appliances and their individual shut-off
valves must be disconnected from the gas
supply piping system during any pressure
testing of that system at pressures in excess
of 1/2 psig (3.5 kPa).
These appliances must not be connected to a
chimney or fl ue serving a separate solid fuel
burning appliance.
Control Compartment Access
The gas controls can be found behind the lower
access door. To access, pull the door open
(see Figure 2).
Millivolt appliances will be fi tted with the gas
control valve shown in Figure 3. Familiarize
yourself with the gas control valve that your
appliance uses.
OPERATION AND CARE OF YOUR
APPLIANCE
Appliance operation may be controlled through
a remotely located optional wall thermostat or
remote control.
In lieu of remote or remote wall thermostat
operation, the appliance must be operated
directly through the on/off rocker switch located
on the upper right side of the rear shield. See
Figure 1.
If your millivolt appliance is equipped with an
optional wall thermostat kit or remote control
kit and the pilot is lit, the appliance main burner
may be turned on and off with the wall thermostat
or remote control.
