Maximum manifold pressure is 3.5 in. w.c. (0.87 kPa) for natural gas and 10 in. w.c. (2.49 kPa) for LP/Propane gas.

Do not use these appliances if any part has been under water. Immediately call a qualified, professional service technician to inspect the appliance and to replace any parts of the control system and any gas control 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 qualifié 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 (identi- fied OUT for the manifold side and IN for inlet pressure. A ¹⁄₈" NPT test gage connection is provided on the electronic gas control valve adjacent to the outlet to the main burner.

Minimum inlet gas pressure to these appliances is 5.0 inches water column (1.24 kPa) for natural gas and 11 inches water column (2.74 kPa) for propane for the purpose of input adjustment.

Maximum inlet gas supply pressure to these appliances is 10.5 inches water column (2.61 kPa) for natural gas and 13.0 inches water column (3.23 kPa) for propane.

The appliance must be isolated from the gas supply piping system (by closing its 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).

The appliance and its individual shut-off valve 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 flue serving a separate solid fuel burning appliance.

Any safety guard or screen removed for servicing the appliance must be replaced prior to operating the appliance.

WARNING: FAILURE TO COMPLY WITH THE INSTALLATION AND OPERATING INSTRUCTIONS PROVIDED IN THIS DOCUMENT WILL RESULT IN AN IMPROPERLY INSTALLED AND OPERATING AP- PLIANCE, VOIDING ITS WARRANTY. ANY CHANGE TO THIS APPLIANCE AND/OR ITS OPERATING CONTROLS IS DANGER- OUS. IMPROPER INSTALLATION OR USE OF THIS APPLIANCE CAN CAUSE SERIOUS INJURY OR DEATH FROM FIRE, BURNS, EXPLOSION OR CARBON MONOXIDE POISONING.

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 profes- sional, as it may not be operating correctly.

WARNING: CHILDREN AND ADULTS SHOULD BE ALERTED TO THE HAZARDS OFHIGHSURFACETEMPERATURES.USE CAUTION AROUND THE APPLIANCE TO AVOID BURNS OR CLOTHING IGNITION. YOUNG CHILDREN SHOULD BE CAREFULLY SUPERVISED WHEN THEY ARE IN THE SAME ROOM AS THE APPLIANCE.

WARNING: DO NOT PLACE CLOTHING OR OTHER FLAMMABLE MATERIALS ON OR NEAR THIS APPLIANCE.

AVERTISSEMENT: SURVEILLER LES ENFANTS. GARDER LES VÊTEMENTS, LES MEUBLES, L'ESSENCE OU AUTRES LIQUIDES À VAPEUR INFLAMMABLES LOIN DE L'APPAREIL.

OPERATION AND CARE OF YOUR APPLIANCE

Appliance operation may be controlled through a remotely located optional wall switch. Separate switches may provide independent control for the remote controlled fireplace operation (optional equipment).

In lieu of remote or remote wall switch opera- tion, the appliance must be operated directly through the controls located on the front of the valve located within the control compartment which is located behind the control compartment access panel below the appliance front glass enclosure panel. See Figure 1.

Gas Controls/Control Compartment Access

The gas controls can be found behind the control compartment access panel.

To open the control compartment access panel, actuate the spring-loaded magnetic catches securing the panel, by gently depressing the outer top corners of the panel until the catches "pop" the door free, allowing it to swing out and down to open.

Operation of millivolt and electronic gas control systems are different. Before lighting and operating your appliance determine if you have a millivolt or electronic appliance. See Figure 1 on page 4 for access to the control compartment.

Millivolt appliances will be fitted with the gas control valve shown in Figure 3 (SIT) or Figure 4 (Honeywell) on page 4. Appliances with electronic systems will be fitted with the electronic valve shown in Figure 2 on page 4.

Familiarize yourself with the gas control valve that your appliance uses.

Millivolt Appliances -

To light millivolt appliances refer to the detailed lighting instructions found on page 12 (En- glish) and page 13 (French). Millivolt appliance lighting instructions may also be found on the pull-out lighting instruction labels attached to the gas control valve.
