8. Viewing Information About the Heater
The electronic control for this water heater monitors many different as-
pects 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 (see Figure 15).
•
You are now ready to begin the burner start-up procedure.
