HL2-DS
Series
When connecting piping to the unit, the use of a thread joint compound is required. The thread
compound (pipe dope) shall be resistant to the action of liquefied petroleum gas or any other
chemical constituents of the gas to be conducted through the piping. Use of Teflon
®
tape is not
permitted.
WARNING
!
Always use two (2) opposing wrenches to tighten mating pipe connections
to prevent excessive torque on the gas valve and manifold pipe. Excessive
torque can damage the valve and/or misalign the orifice, resulting in fire,
explosion, serious injury, or death.
Leak Testing
Always leak test final gas assembly for gas leaks according to the procedures outlined in NFPA 54 and
all local codes and/or Standards.
For leak testing on pressures below ½” PSI
Before leak testing, close the field installed manual shut off valve shown on Figure 3.14 on the supply
line to isolate the gas valve from the pressure.
NOTE:
All factory installed gas connections have passed an approved leak test.
For leak testing on pressures above ½” PSI
When leak testing with pressures above ½” PSI (14” W.C.), the unit must be isolated from the supply
pipe. Close the field installed manual shut off valve, disconnect the supply line to the unit, and
temporarily cap the supply line for testing purposes.
WARNING
!
Use a soap solution or equivalent for leak testing. Never test for leak with an open
flame. Failure to comply could result in personal injury, property damage, or death.
WARNING
!
Gas pressures to the appliance controls must never exceed 14” W.C. (1/2” PSI). Supply
pressures greater than 14” W.C. can damage the controls, resulting in personal injury,
property damage, or death.
