CHECKING FOR GAS LEAKS
DANGER! To prevent fire or explosion, DO NOT smoke or allow any potential source of ignition (sparks, electrical
arcing, cell phones, etc.) in the area while performing a leak test. Leak tests should be conducted outdoors only.
Never conduct a leak test using fire or open flame.

Never conduct a leak test using fire or open flame.
The following leak test proceedure is to be performed on all newly installed gas pipes, fittings, and connections:
1. Create a soapy solution of 1 part dish soap and 3 parts water.
2. Turn ON the fuel supply. For Natural Gas (NG), turn the in-line manual gas shut-off lever ¼ turn so that the lever

is parallel and in-line with the pipe or hose. For Liquid Propane (LP) , open the gas cyinder knob by a minimum of
1 full turn and if connected to the Lynx LQD-EM, turn the in-line valve ¼ turn so that the lever is parallel and in-
line with the hose.

3. Apply the soap solution by squirt bottle or paint brush on all connections and fittings.
4. If bubbles appear to ‘grow’ on any of the connections, you have a gas leak. IMMEDIATELY turn OFF the gas

FIXING A GAS LEAK:
1. At the identified point of leakage, assure that the joint was sealed with gas pipe compound or Teflon sealing
tape. If either of these are missing, then the connection must be unassembled and reassembled with proper
sealing compound.
sealing compound.
2. If the connection has the proper sealing compound, then tighten the fittings further. Re-apply the soap solution
and re-test for gas leaks.
3. If gas leak still exists, then it is recommended that the entire section of pipe and fittings around the leak be
unassembled. Examine each fitting and assure that all threads are ‘true’ and that no fittings or pipe have
deformation. If so, replace them with new fittings. Once again, apply sealing compound around all joints and re-
assemble the pipes and fittings. If a flexible gas line is being used to connect the heater to the hard piping, and
the leak is at that section, then be certain the fitting attached to the heater is the proper ½” MIP fitting, and the
fitting at the other end is also a ½” MIP fitting used with a ½” coupling to join to the ½” pipe. Very often, a flex
hose such as this is created with removable fittings at the ends to create the ½” MIP thread. These removable
fittings themselves use a flare thread, and not a pipe thread. NEVER USE SEALING COMPOUND OR TEFLON
TAPE ON FLARED FITTINGS.
