Raypak 503 thru 2003 Water Heater User Manual


 
1. Control Panel
Fully enclosed controls and wiring protect
against damage or vandalism. Cabinet design
affords easy access to controls for installation
and service.
2. Temp-Tracker Mod Control
This factory-mounted multi-function control
delivers precise load-tracking with selectable
mode displays that are easy to access and read.
3. Universal Diagnostics Board
12 LEDs monitor up to 22 safety
circuits and store up to 256 fault codes.
4. Weather-Proof Jacket
Heavy gauge galvanized steel with
a UV-resistant Polytuf powder coat finish is
impervious to weather and corrosion.
5. Combustion Air Fan
Cast aluminum, non-sparking construction.
6. Vent Pressure Switch
Monitors vent pressure and provides safe shut
down if back pressure is excessive.
7. Minimum Clearance Requirements
Only one inch of side clearance is required from
combustible surfaces.
8. Vertical Heat Exchanger
Cylindrical, multi-pass heat exchanger captures
all radiant energy, eliminating the need for
heavy refractory.
9. Rugged All-Bronze Headers
The proven choice for all applications.
10. Tube Sheet Construction
Eliminates the repair & maintenance problems
associated with rolled-tube construction. Easy,
cost-effective component replacement.

Cold Water Solutions
Cold Water Start – For applications that
require reliable protection against harmful con-
densation caused by frequent, extended, cold
water start-ups. Raypak’s Cold Water Start pro-
tection system utilizes a proportional three-
way valve to bypass water from the boiler out-
let to the inlet during start-up, when the sys-
tem return water temperature is below the minimum acceptable
level. (See Cat. #1000.19)
Cold Water Run – For applications requir-
ing constant condensation protection. Raypak’s
Cold Water Run system utilizes a variable-
speed pump to inject just the right amount of
water from the main system loop into the boil-
er to maintain the optimum inlet temperature.
This approach allows the full capacity of the
boiler to be utilized to meet the system load,
while at the same time continuously maintaining the optimum inlet
water temperature to prevent condensation. (See Cat. #1000.19)
Multi Boiler Solutions
Y-200 Boiler Sequencer – Provides addi-
tional functionality for multiple-boiler installa-
tions. Controls up to 8 MVB boilers with full
PID logic. LonMarkcertified interface ensures
seamless compatibility with LonWorks
Building Management Systems (BMS)
(See Cat. #5100.22)
TempTracker Mod+ – Controls up to 16
Raypak MVBs with P or PID logic. Automatic or
manually selectable lead-lag boiler operation.
TempTracker Mod+ monitors and displays sup-
ply water temperatures on all applications
including outdoor temperature when outdoor
reset mode is selected. (See Cat. # 5100.22)
