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 con- trôle et toute commande qui ont été plongés dans l'leau.

Test gage connections are provided on the front of the millivolt and electronic gas control valve (identified 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 appli- ances 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

Any safety guard or screen removed for ser- vicing 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 im- properly installed and operating appliance, voiding its warranty. Any change to this appliance and/or its operating controls is dangerous. Improper instal- lation 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 andhaveitservicedbyaqualifiedprofessional, 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 care- fully 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.

Operation and care of your appliance

Appliance operation may be controlled by the following means: the factory provided unit- mounted ON-OFF control switch, a remotely located optional wall switch or optional remote control. See Figure 1.

Burn-in Period

During the first few fires of this appliance there will be some odor due to the curing of the paint and burning off of lubricants used in the manufacturing process.

Depending on your use, the burn-in period may take a few hours or a few days.

KEEP YOUR HOUSE WELL VENTILATED DURING THE CURING PROCESS. THE ODOR AND HAZE EMITTED DURING THE CURING PROCESS CAN BE QUITE NOTICEABLE AND MAY SET OFF A SMOKE DETECTOR.

If an optional blower is installed, Do not turn it on during the Burn-In period.

A white film may develop on the glass front during the first few fires as part of the curing process. The glass should be kept clean during the first two weeks of use to prevent the film from baking on (making it very difficult to remove). See Glass Cleaning on Page 4.

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 manualshut-offvalve)duringanypressuretesting 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.
