8. Viewing Information About the Heater
The electronic control for this water heater monitors many different aspects
of the water to ensure safe and optimal operation. Much of the information
monitored is available to view in two areas of the control. The first is the
"Heater Status" and; the second is "Heater Information." These items can be
selected through the main menu in the same fashion as described above.
In these menus, detailed information about the water heater and the current
status of specific conditions can be found.
INSTALLATION OR SERVICE OF THIS WATER HEATER REQUIRES
ABILITY EQUIVALENT TO THAT OF A LICENSED TRADESMAN IN THE
FIELD INVOLVED. PLUMBING, AIR SUPPLY, VENTING, GAS SUPPLY
AND ELECTRICAL WORK ARE REQUIRED.
Before attempting start-up, thoroughly study and familiarize yourself with
the exact sequence of operation and all other details on the specific heater
being used.
The power burner is equipped with an ignition system which automatically
sequences prepurge and ignition, senses and ignites main burner flame and
sequences burner operation. Heater is equipped with an ignition control which
locks out after three unsuccessful ignition attempts. Familiarize yourself with
the sequence of operation of this unit prior to start-up.
Be certain that the water heater is full of water, that air is purged from all lines,
there are no leaks (gas and water), and all inlet water lines are open.
The following test equipment should be on hand (all test equipment must be
acclimated to ambient temperature before calibration and use.)
– Two U-tube manometers or calibrated pressure gages that can read
0-10" (0-2.5Kpa) and 0-35" (0-8.7Kpa) W.C. pressure gauges.
• Attach a gas pressure gauge or manometer to the upstream side of
main gas cock and a gas pressure gauge or manometer to the manifold
pressure tap.
• You are now ready to begin the burner start-up procedure.
