8. Have all connections made at the storage tank by a licensed Propane Gas installer.
9. Have Propane 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.
All joints must be tested for leaks by applying pressure to the piping system. If the test pressure is equal to or less than 1/2
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 1/2 PSIG, the floor furnace and its manual gas shut-offvalve 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. Overfrring 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 OFIGNITION 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.

CHECKING THE GAS PIPING
Refer to Figure 10 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
Propane 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.
