IMPORTANT INFORMATION

Do not use this appliance if any part has been submerged under water. Immediately call a qualied service
technician to inspect the appliance and to replace any part of the control system and any gas control which has
been under water.

This heater shall not be installed in a conned space unless provisions are provided for adequate combustion
and ventilation air. The National Fuel Gas Code denes a conned space as a space whose volume is less
than 50 cubic feet per 1,000 BTU per hour (4.8m3 per kw) of the aggregate input rating of all appliances
installed in that space and an unconned space as a space whose volume is not less that 50 cubic feet per
1,000 BTU per hour (4.8m3 per kw) of the aggregate input rating of all appliances installed in that space.
Rooms communicating directly with the space in which the appliances are installed, through openings not
furnished with doors, are considered a part of the unconned space

WARNING: If the area in which the heater may be operated is smaller than that dened as an

unconned space provide adequate combustion and ventilation air by one of the methods

described in the National Fuel Gas Code, ANSI z223.1, 1992, Section 5.3

This appliance is equipped with an ODS (oxygen depletion sensor) pilot light safety system that turns off the
appliance if enough fresh air is not available. Additional ventilation is obtained by opening a door to another
room or opening a window.

Always ensure that there is proper ventilation from the area the system is operating in.

Any outside air ducts and/or ash dumps in the replace shall be permanently closed at time of
appliance installation.

This appliance must be used with glass doors in the OPEN position.

A replace screen with an opening for combustion air must be in place when the appliance is operating, unless
other provisions for combustion air are provided.

IMPORTANT: During the manufacturing process this appliance is treated with certain coloring agents. These

agents are not harmful, but may produce annoying smoke and smell as they are burned off. This
is a temporary occurrence that ceases after 4 to 6 hours of use. During the “burning off” period,
provide ventilation by opening windows, doors and the chimney ue to allow odors to dissipate.
Any remaining odors will burn off with continued use.

GAS PIPING AND GAS PRESSURE REQUIREMENTS

Check the type of gas that is supplied to your replace. Use only the gas type indicated on the heater’s rating
plate. If the gas listed on the plate is not your type of gas supply, DO NOT INSTALL THE SYSTEM. Contact
your dealer for the proper model.

All gas piping must be installed to comply with local and national fuel gas codes. Do not use exible hose
unless it is allowed by local codes. Compounds used on threaded joints of gas piping musts be resistant to the
action of LP gas.

The gas supply line to the replace should not be less than 1/2” inside dimension.

The gas supply must be of sufcient size to provide a minimum natural gas pressure of 7 inches water column
for natural gas or 11 inches for L.P. gas. The maximum inlet gas pressure to the appliance must not exceed
10 inches for natural gas and 13 inches for L.P. gas. If this appliance is to be supplied with L.P. gas the tank
or bottle supplying the gas must have a regulator that reduces gas pressure between 11 and 13 inches water
column.

Include a manual shutoff valve and union in the line so the appliance may be disconnected for servicing.
Provide a 1/8” NPT plugged tapping for pressure gauge connection between shutoff valve and the appliance.
Test for leaks using soap and water solution after completing the connection. DO NOT USE OPEN FLAME!

WARNING: The appliance and its individual shutoff valve must be disconnected from the gas supply

piping system during any pressure testing of that system at test pressures in excess of
1/2 psig (3.5 kPa). The appliance must be isolated from the gas supply piping system by
closing its individual manual shutoff valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than 1/2 psig. Pressures in excess of 1/2
psig will cause damage to the unit.

FIREPLACE CLEARANCES

To guarantee safe installation into a noncombustible replace, certain space requirements must be fullled.

1. The clearance from the side of the unit to any combustible wall should not be less than 15 1/2 inches.

2. The clearance from the ceiling to the top of the replace opening should not be less than 42 inches.

3. The minimum clearance to combustible items in front of the heat is 36 inches.

4. For any replace in which this unit is installed, there are certain mantel clearance requirements that
must be met.

Minimum Mantel Clearance Minimum Mantel Clearance with Canopy

You must have non-combustible material(s) above the replace opening. Non-combustible materials (such as
slate, marble, tile, etc.) must be at least 1/2 inch thick. Some decorative replace surrounds (cultured marble)
may get discolored from the heat produced by the system. With sheet metal, you must have non-combustible
material behind it. If non-combustible material is less than 8” you must install replace canopy
(Model AMG-100).
