All gas piping must be installed to comply with local and national fuel gas codes. Do not use flexible hose unless it is
allowed by local codes. Compounds used on threaded joints of gas piping must be resistant to the action of LP gas.
The gas supply line to the fireplace should not be less than 1/2” inside dimension.
The gas supply must be of sufficient size to provide a minimum natural gas pressure of 7 inches water column for natural
gas or 11 inches for LP gas. The maximum inlet pressure to the appliance must not exceed 10 inches water column
for Natural Gas or 13 inches water column for LP gas. If this appliance is to be supplied with LP 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 shut-off 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 the shut-off 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 shut-off 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 (3.5kPa). 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. Pressures in
excess of 1/2 PSIG will cause damage to the unit.
FIREPLACE CLEARANCES
To guarantee safe installation into a non-combustible fireplace, certain space requirements must be fulfilled.
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 fireplace opening should not be less than 42 inches.
3. The minimum clearance to combustible items in front of the heater is 36 inches.
4. For any fireplace in which this unit is installed, there are certain mantel clearance requirements that must be met.
You must have non-combustible material(s) above the fireplace opening. Non-combustible materials (such as slate, marble,
tile, etc.) must be at least 1/2 inch thick. Some decorative fireplace 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-com-
bustible material is less than 8”, you must install fireplace canopy (Model AMG-100)
