WARNING

These fireplaces are vented decorative gas appliances. Do not burn wood or other material in these appliances.

These appliances are designed to operate on natural or propane gas only.

Millivolt Models -

Millivolt models come standard with the manually -modulated gas valve; flame appearance and heat output can be controlled at the gas valve.

All Models -

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.

Installations at Altitudes of 0 to 4500 ft.- Units are tested and approved for elevations of 0 to 4500 feet (0 to 1372 meters).

Installations at Altitudes above 4500 ft.- 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.Table 3 shows the units' gas orifice size for the elevations indicated.Burner Orifice SizesElevation 0-4500 feet ( 0-1372 meters)

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'lau.

This appliance may be installed in an after- market permanently located, manufactured home (USA only) or mobile home, where not prohibited by local codes. This appliance is only for use with the type of gas indicated on the rating plate. This appliance is not convertible for use with other gases, unless a certified kit is used.

Cet appareil peut être installé dans un maison préfabriquée (É.-U. seulement) ou mobile déjà installée à demeure si les réglements locaux le permettent.

Cet appareil doit être utilisé uniquement avec les types de gaz indiqués sur la plaque signalétique. Ne pas l'utiliser avec d'autres gaz sauf si un kit de conversion certifié est installé.

Millivolt appliances are fitted with a SIT millivolt gas control valve and have been tested with and approved for use with this valve and are listed accordingly.

Test gauge connections are provided on the front of the millivolt gas control valves (identified OUT for the manifold side and IN for inlet pressure side). A 1/8" NPT test gauge connection is provided on the electronic gas control valve adjacent to the outlet to the main burner.

Minimum inlet gas pressure to the appliance is

5.0inches 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 the ap- pliance is 10.5 inches water column (2.61kPa) 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 psig (3.5) kPa).

The appliance and its individual shut-off valve must be disconnected from the gas supply piping systemduringanypressuretestingofthatsystem at pressures in excess of psig (3.5 kPa).

These appliances must not be connected to a chimney or flue serving a separate solid fuel burning appliance.

Do not place clothing or other materials on or near this appliance.

WARNING

Failure to comply with the installation and operating instructions provided in this document will result in an improperly installed and operating appliance, voiding its warranty. Any change to this appliance and/or its operating controls is dangerous. Improper installation or use of this appliance can cause serious injury or death form fire, burns, explosion or carbon monoxide poisoning.
