SECTION 3.

Gas Supply and Piping

3.1 Gas Supply and Piping

Gas piping should be supported by suitable

hangers or floor stands, not by the appliance.

The Copper Brute II 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 heaters are equipped to operate at

elevations up to 10000 feet (3050m). Copper

Brute II heaters may be adjusted to operate

properly at altitudes above 2500 feet (see Section

6.4.2) 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.

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
