GAS SUPPLY AND PIPING
ADDITIONAL PROPANE GAS REQUIREMENTS
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.
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 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-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. 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 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.
When you have determined that there are no leaks in
the gas piping system you may purge the system of air.
Disconnect the pilot supply tubing from the right side of
the valve. Figure 12
Turn the knob on the gas valve to the pilot position. Press
the knob down and hold until you smell gas at the pilot
supply opening. Release the knob and tum it to the off
position. Reconnect the pilot supply tubing and check for
leaks with soap and water or liquid detergent.

GAS FIRED VENTED
FLOOR FURNACES
WARNING: When purging gas piping, the area
around the floor furnace must be well ventilated to
allow any gas to dissipate. Liquid Petroleum (Propane)
Gas is heavier than air and may puddle in low places
under the floor. Check thoroughly to determine that
no gas is present before lighting the floor furnace.
Failure to do so could result in property damage,
bodily injury or death.
