SECTION 3.

Gas Supply and Piping

3.1Gas Supply and Piping

Gas piping should be supported by suitable

hangers or floor stands, not by the appliance.

The Copper Brute II’s gas train allows the user to pipe the gas from either the right side or the left side of the unit. As shipped, the right side of the gas train is capped off, and there is a manual valve on the left side. If desired, the manual valve on the left side of the gas train may be moved to the right side, and the cap on the right side may be moved to the left.

Review the following instructions before proceeding with the installation.

1.Verify that the appliance is fitted for the proper type of gas by checking the rating plate. Copper

Brute II appliances are equipped to operate at elevations up to 10,000 feet (3050m). Copper

Brute II appliances may be adjusted to operate properly at altitudes above 2500 feet (see Section 6.5.2) and the input will be reduced if the heating value of the gas supply is below sea level values.

2.The maximum inlet gas pressure must not exceed 13" w.c. (3.2kPa). The minimum inlet gas pressure is 5" w.c. (1.2kPa).

3.Refer to Table 7, size supply.

4.Run gas supply line in accordance with all applicable codes.

5.Locate and install manual shutoff valves in accordance with state and local requirements.

6.A sediment trap must be provided upstream of the gas controls.

7.All threaded joints should be coated with piping compound resistant to action of liquefied petroleum gas.

8.The appliance and its individual shutoff valve must be disconnected from the gas supply piping during any pressure testing of that system at test pressures in excess of 1/2 PSIG (3.45kpa).

9.The unit must be isolated from the gas supply 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 (3.45kpa).

10.The appliance and its gas connection must be leak tested before placing it in operation.

11.Purge all air from gas lines.

WARNING

Do not use open flame to check for leaks. An open flame could lead to explosion, which could result in property damage, serious injury or death.

NOTE: The Copper Brute II appliance and all other gas appliances sharing the gas supply line must be firing at maximum capacity to properly measure the inlet supply pressure. The pressure can be measured at the supply pressure port on the gas valve. Low gas pressure could be an indication of an undersized gas meter, undersized gas supply lines and/or an obstructed gas supply line.

Notes:

1.These figures are based on 1/2" (0.12kPa) water column pressure drop.

2.Check supply pressure and local code requirements before proceeding with work. 3.Pipe fittings must be considered when determining gas pipe sizing.
