Table 1

Units are tested and approved for elevations of 0 to 4500 feet (0 to 1372 meters).

For elevations above 4500 feet (1372 meters), install the unit according to the regulations of the local authorities having jurisdiction and, in the USA, the latest edition of the National Fuel Gas Code (ANSI Z223.1) or, in Canada, the latest edition of the CAN1-B149.1 and .2 codes.

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.

The minimum manifold pressure on low is 2.2 in. w.c. (0.55 kPa) for natural gas and 6.3 in. w.c. (1.57 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.

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 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 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).

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 OPER- ATING INSTRUCTIONS PROVIDED IN THIS DOCUMENT WILL RESULT IN AN IMPROPERLY INSTALLED AND OP- ERATING APPLIANCE, VOIDING ITS WARRANTY. ANY CHANGE TO THIS APPLIANCE AND/OR ITS OPERATING CONTROLS IS DANGEROUS. IM- PROPER INSTALLATION OR USE OF THIS APPLIANCE CAN CAUSE SERI- OUS 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 immediately. Turn off the gas sup- ply to the appliance and have it serviced by a qualified professional, as it may not be operating correctly.

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

The appliance must be isolated from the gas supply piping system (by closing its individual manual shut-off valve) during any pressure test- ing of the gas supply piping system at test pres- sures equal to or less than 1/2 psig (3.5 kPa).

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

WARNING: CHILDREN AND ADULTS SHOULD BE ALERTED TO THE HAZ- ARDS OF HIGH SURFACE TEMPERA- TURES. USE CAUTION AROUND THE APPLIANCE TO AVOID BURNS OR CLOTHING IGNITION. YOUNG CHIL- DREN SHOULD BE CAREFULLY SUPER- VISED WHEN THEY ARE IN THE SAME ROOM AS THE APPLIANCE.

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 electronic gas control valve (iden- tified 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.
