START UP CONDITIONS
SMOKE/ODOR
It is not uncommon to experience a small amount of smoke and odor
during the initial start-up. This is due to burning off of oil from metal
parts, and will disappear in a short while.
PRIOR TO START UP
Installation and start up of this water heater requires abilities and
skills equivalent to that of a licensed tradesman in the field involved,
see Qualifications on page 8.
DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN
EXPOSED TO FLOODING OR WATER DAMAGE. Immediately
call a qualified service technician to inspect the water heater and
to make a determination on what steps should be taken next.
Light the water heater in accordance with the Lighting and
Operation Instruction label on the water heater and in this manual
on page 46.
The water heaters covered by this manual are equipped with
an electronic control system (see page 36) which automatically
sequences the Combustion Blower, pre and post purging of the
combustion chamber, the spark transformer, the 24 Volt Gas Control
Valve, Main Burner Ignition, and flame sensing. The control system
will lock out after three unsuccessful ignition attempts.
Before attempting start up, thoroughly study and familiarize
yourself with the exact Sequence of Operation. See the Sequence
of Operation Flow Chart on page 49. Ensure the water heater is
properly grounded. Flame sensing requires an adequate earth
ground. If the water heater is not properly grounded it will cause
Ignition Failure. See Electrical Wiring on page 33.
Be certain that the water heater is full of water, that air is purged
from the gas and water lines and that there are no leaks in the gas
and water lines. Ensure all inlet water valves are open.
FILLING THE WATER HEATER
Never use this water heater unless it is completely full of water.
To prevent damage to the tank, the tank must be filled with water.
Water must flow from the hot water faucet before turning ON gas
to the water heater.
To fill the water heater with water:
1. Locate the drain valve at the base of the water heater behind
the access panel. See Features and Components beginning
on Page 11.
2. Close the water heater drain valve by turning the handle to
the right (clockwise).
3. Open the cold water supply valve to the water heater.
NOTE: The cold water supply valve must be left open when
the water heater is in use.
4. To insure complete filling of the tank, allow air to exit by
opening the nearest hot water faucet. Allow water to run until
a constant flow is obtained. This will let air out of the water
heater and piping.
5. Check all water piping and connections for leaks. Repair as
needed. See Gas Line Leak Testing on Page 32.
