Battery Installation

The TESC valve requires three, AA alkaline batteries be
installed within the central battery compartment. The
batteries supplied in the stove hardware kit were used
to test the valve and burner functions at the factory,
however, these have been removed before shipping. Note
the proper battery orientation as molded into the battery
compartment.
Testing Gas Pressure
Correct gas pressure is important for the safe use of gas in
the appliance. It is important that the correct gas pressure
is set during the installation of the appliance.
The gas plumbing assembly is equipped with outlets
(taps) for the testing of gas pressure. See Fig. 16a and the
identification list below.
• Supply Inlet: See Technical Data, page 4 for supply
pressure to the valve (volume of gas to the valve).
Access to the supply tap is from the rear.
• Manifold Outlet: Access is from the left side as you face
the stove. Test the gas pressure with the valve flame
regulator set to the highest level.
Loosen the screw in the tap and attach the tube from the
manometer to the outlet. Remember to tighten the screw
when the testing is completed and test for leaks at each
location with test fluid or a digital detector.
Required gas pressure from the valve outlet is displayed
in the table below. (Note that the installer is required
to operate the appliance for at least 20 minutes before
measuring the burner pressure.

Inspection of the Pilot Flame
The pilot assembly flame should have two flames as
shown in fig. 17. The rear flame should fully engulf the
thermo-element that controls gas flow through the valve.
The forward flame ignites the burner. Each flame should
project out approximately 30 mm and be unobstructed.
The flames should be stable and the colour mainly
blue. Call for service if any of these characteristics are
evident:
• weak, lifting, or wandering flame
• yellow or dirty flame
