Not
recommendable
but in case of
emergency
You must use a torque wrench but if you are obliged to install the unit without a torque wrench,
you may follow the installation method mentioned below.
After the work is finished, make sure to check that is no gas leak.
When you keep on tightening the flare nut with a spanner, there is a point where the tightening
torque suddenly increases. From that position, further tighten the flare nut the angle shown
below:
➈
Tighten the flare nut.
(Use a torque wrench to apply the proper
tightening force.)
➉
Check for gas leaks.
(Check at the threaded section of the flare nut for
gas leaks.)
Spray-type gas leak detecting products are
available on the market. Soap water may be used
to check for leaks, but use only neutral soap to
prevent corrosion on the flare nut.
Be sure to wipe the nut area clean after the gas
leak check.
Tighten the flare but with proper torque.
It takes a lot of experience to tighten the flare nut properly without the use of a torque wrench.
