PRIOR TO START UP
IMPORTANT
IT IS REQUIRED THAT A QUALIFIED PERSON PERFORM THE
INITIAL FIRING OF THE HEATER. AT THIS TIME THE USER
SHOULD NOT HESITATE TO ASK THE INDIVIDUAL ANY
QUESTIONS WHICH HE MAY HAVE IN REGARD TO THE
OPERATION AND MAINTENANCE OF THE UNIT.
A CHECKLIST AND SERVICE INFORMATION section is included
at the rear of this manual. By using this checklist the user may
be able to make minor operational adjustments and save himself
unnecessary service calls. However, the user should not attempt
repairs which are not listed in this section.
REQUIRED EQUIPMENT AND ABILITY
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 a direct spark ignition system
and automatically sequences prepurge and ignition, senses and
ignites main burner flame and sequences burner operation.
Heater is equipped with an ignition module which locks out after
an unsuccessful ignition attempt. Turn off electric power for ten
seconds before restarting.
Be certain that water heater is full of water, that air is purged from
all lines, 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.)
–
CO
2
indicator (Fyrite or similar) or O
2
analyzer
–
CO indicator (Monoxor or similar)
–
Stack thermometer
–
Draft Gauge or inclined manometer
–
Two U-tube manometers or calibrated 0-10" and 0-35"
w.c. pressure gauges.
–
Combination volt/ammeter.
•
Attach a gas pressure gauge or manometer to upstream side
of main gas cock and a gas pressure gauge or manometer to
the manifold pressure tapping.
•
Check voltage at disconnect switch to make certain that it
matches that shown on the burner label.
•
Apply a few drops of No. 20 SAE non-detergent oil to motor
bearings.
•
Drill max. 5/16" hole in breeching as close as possible to flue
connection on heater to install stack thermometer and
combustion analyzing equipment. (See fig. 4).
•
You are now ready to begin the burner start up procedure.
Follow the OPERATIONAL PROCEDURE in the OPERATIONAL
AND ADJUSTMENT PROCEDURE section of this manual.
PURGING
Gas line purging is required with new piping or systems in which
air has entered.
CAUTION
PURGING SHOULD BE PERFORMED BY PERSONS
EXPERIENCED IN THIS TYPE GAS SERVICE. TO AVOID RISK
OF FIRE OR EXPLOSION, PURGE DISCHARGE MUST NOT
ENTER CONFINED AREAS OR SPACES WHERE IGNITION
CAN OCCUR. THE AREA MUST BE WELL VENTILATED AND
ALL SOURCES OF IGNITION MUST BE INACTIVATED OR
REMOVED.
WATER TEMPERATURE CONTROL
DANGER
THIS WATER HEATER IS EQUIPPED WITH AN ADJUSTABLE
THERMOSTAT TO CONTROL WATER TEMPERATURE. HOT
WATER TEMPERATURES REQUIRED FOR AUTOMATIC
DISHWASHER AND LAUNDRY USE CAN CAUSE SCALD
BURNS RESULTING IN SERIOUS PERSONAL INJURY AND/
OR DEATH. THE TEMPERATURE AT WHICH INJURY OCCURS
VARIES WITH THE PERSON’S AGE AND TIME OF EXPOSURE.
THE SLOWER RESPONSE TIME OF CHILDREN, AGED OR
DISABLED PERSONS INCREASES THE HAZARDS TO THEM.
NEVER ALLOW SMALL CHILDREN TO USE A HOT WATER TAP,
OR TO DRAW THEIR OWN BATH WATER. NEVER LEAVE A
CHILD OR DISABLED PERSON UNATTENDED IN A BATHTUB
OR SHOWER.
THE WATER HEATER SHOULD BE LOCATED IN AN AREA
WHERE THE GENERAL PUBLIC DOES NOT HAVE ACCESS
TO SET TEMPERATURES.
SETTING THE WATER HEATER TEMPERATURE AT 120°F
WILL REDUCE THE RISK OF SCALDS
. Some states or provinces
require settings at specific lower temperatures.
Below you will find listed Table 5 the approximate time-to-burn
relationship for normal adult skin. Short repeated heating cycles
caused by small hot water uses can cause temperatures at the
point of use to exceed the thermostat setting by up to 20°F (11°C).
If you experience this type of use, you should consider using
lower temperature settings to reduce scald hazards.
