Secure all joints tightly using appropriate tools and
sealing compounds (for propane units, be sure to use
compounds that are propane resistant). Turn on gas
supply and test for gas leaks using a soapy water
solution. Never use an open flame to check for leaks.

····· Mix a 50-50 solution of water and dish soap.
····· Light appliance - See lighting instructions on page 23
of this manual or on the rating plate.
····· Brush or spray all joints and connections with the
soapy water solution.
····· If bubbles appear at any connection or seam or a gas
odor is detected, immediately turn gas control knob
to the OFF position.
Tighten or reconnect the leaking joint and retest for any
gas leaks.
Gas Pressures
Correct gas pressure is essential for efficient and safe
operation of the Katahdin gas insert. It is important that
the correct pressure is established at the time of the
installation.
Proper gas pressure provides a consistent flow of
gas to the appliance and is instrumental in checking for
gas leaks.The gas control valve on the insert is equipped
with pressure test points for gauge connections. The
gauge connections are located on the front of the valve
under the On/Off/Pilot knob. See fig. 13.

The appliance must be isolated from the gas supply
line by closing its individual manual gas shut-off valve
(gas cock) during any pressure testing of the gas supply
piping system that is equal to or exceeds pressures
of 1/2 psig (3.5kPa).
