Typical Gas Piping ('aMP)

25-25-02

Piping with Street Elbows

1.Screw one elbow onto gas valve with the outlet facing away from the furnace.

2.Screw second elbow onto first elbow tight enough to be leak proof. An additional 1/4 turn will be required at the end of step 2. See Figure 17 and Figure 18.

Gas Valve with Elbows ('8MP)

2.Follow steps 2 through 4 Piping with Street Elbows.

FIRE OR EXPLOSION HAZARD.

Failure to properly install metal gas connector could

result in death, personal injury and/or property damage.

A flexible corrugated metal gas connector must be properly installed, shall not extend through the side

of the furnace, and shall not be used inside the furnace.

Black iron pipe shall be installed at the furnace gas control valve and extend a minimum of 2" outside

furnace.

Additional LP Piping Requirements

•Have a licensed LP gas dealer make all connections at stor-

age tank and check all connections from tank to furnace.

•If copper tubing is used, it MUST comply with limitation set in Local Codes, or in the absence of local codes, the gas codes of the country having jurisdiction.

•Two-stage regulation of LP gas is recommended.

Gas Valve with Elbows (_8MP)

3.Gas supply line then can be run directly into opening of elbow.

Piping with Close Nipples and Standard Elbows

1.Assemble elbows and nipples similar to street elbows shown in Figure 13.

FIRE OR EXPLOSION HAZARD.

An open flame or spark could result in death, personal injury and/or property damage.

Liquefied petroleum (LP) gas is heavier than air and will settle and remain in low areas and open depressions.

Thoroughly ventilate area and dissipate gas. Do NOT use a match or open flame to test for leaks, or attempt to start up furnace before thoroughly ventilating area.

Final Check

•Test all pipe for leaks.

•If orifices were changed, make sure they are checked for leaks.

During pressure testing of gas supply piping system:

a.If test pressure does not exceed 1/2" psi, isolate the furnace from the gas supply piping system by closing the

equipment shutoff valve.

b.If test pressure exceeds 1/2" psi, the furnace and its manual

equipment shutoff valve must be disconnected from the gas supply piping system.

To check for leaks apply soap suds or a liquid detergent to each joint. Bubbles forming indicate a leak.

Do not use an open flame to test for gas leaks. Fire or explo- sion could occur.

•Correct even the smallest leak at once.
