CONNECTING THE GAS PIPING

Refer to Figure 11 for the basic fittings you will need at the furnace.

1.Use black iron or steel pipe and fittings or other pipe and fittings that are approved by local codes.

2.Use pipe joint compound that is resistant to the action of Liquefied Petroleum (L.P.) Gas or to any other chemical constituents of the gases to be conducted through the piping only on male threads.

3.Use two wrenches when making the connection to the valve to keep from bending the mounting bracket or manifold pipe. Do not overtighten as damage to the valve can occur.

4.Provide a 1/8” nominal pipe thread (NPT) plugged tapping for test gauge connection immediately upstream of the gas supply connection to the floor furnace.

5.Provide a sediment trap at least 6 inches long to trap dirt and moisture. Provide space to permit cleaning or emptying.

6.Use a ground joint union.

7.Install an approved manual shut-off valve.

ADDITIONAL L.P. GAS REQUIREMENTS

8.Have all connections made at the storage tank by a licensed L.P. Gas installer.

9.Have L.P. Installer check all lines, piping, and connections from the storage tank to the floor furnace when the floor furnace is connected to the storage tank.

10.The regulator on the storage tank should be set at 11 inches water column.

CHECKING THE GAS PIPING

All joints must be tested for leaks by applying pressure to the piping system. If the test pressure is equal to or less than ½ PSIG the floor furnace must be isolated from the gas supply piping system by closing the manual gas shut-off valve on the floor furnace. If the test pressure exceeds ½ PSIG, the floor furnace and its manual gas shut-off valve must be disconnected

from the gas piping system before testing. Failure to do so may result in damage to the pressure regulator in the gas valve resulting in overfiring. Overfiring can result in combustion chamber failure, property damage, bodily injury or death.

Use a mixture of soap and water or liquid detergent to check each joint. Leaks will be indicated by bubbles forming. Correct even the smallest leak at once. Since some soaps may cause corrosion, or stress cracking, rinse the gas piping exterior with water after testing to remove the soap.

WARNING

Never use a match, candle, open flame or other method which could provide a source of ignition to test for leaks. To do so may result in property damage, bodily injury or death.

CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.
