The discharge opening[...]

(a) Seal any unused openings in the common venting system. (b) Visually inspect the venting system for proper size and horizontal pitch and determine there is no blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition. (c) Insofar as is practical, close all building doors and windows and all doors be[...]

GAS PRESSURE REGULATOR The gas pressure regulator is preset and sealed at 4 in. WC for natural gas, and 11 in. WC for propane gas. Between the gas valve and the burners is a 1/8" pipe plug. The pressure at this point, taken with a manometer, should be about 3.7 in. WC natural gas and 10.5 in. WC propane gas. If an adjustment is needed, remove [...]

When local codes permit the use of less than four feet high temperature piping or two elbows, provisions should be made to always shut the heater off a minimum of 15 minutes prior to pump shut down in order to carry away residual heat and prevent damage to the low temperature piping. A fireman switch included in the time clock may be used for this [...]

10 Raypak recommends the installation of an air bleed vent at a suitable location (usually the highest point) to remove air from the piping system. These units should be available at your local wholesale supplier. Raypak does not provide this item. CAUTION: Power to the heater should be interlocked with the main system pump to make sure the heater [...]

Note: The drawings and instructions above show only one of several acceptable ways of installing the dry well into main system loop. The use of saddle clamps and “Weld O Lets” (shown in Fig. 10) are acceptable. Follow clamp manufacturer’s instructions.

4. If the heater inlet temperature remains less than 100°F and Valve "A" is fully open, leave Valve "A" fully open and throttle Valve "B" until the heater inlet temperature rises to within the range of 100°F-105°F. 5. The resultant heater outlet temperature should be in the range of 120-130°F. 6. As the pool temper[...]

TEMPERATURE CONTROL The pool water temperature is controlled by the pool thermostat. The heater water temperature high limit is controlled by the manual reset high limit. PRESSURE SWITCH The pressure switch, or heater actuator, ensures that the heater operates only when the filter pump is in operation. It is factory set at 1.75 PSI for deck level i[...]

AFTER START-UP Pilot System Checkout Procedure 1. Turn on power to the ignition systems and turn gas supply off. 2. Check ignition module as follows: a. Set the thermostat above pool water temperature to turn heater on. b. Watch for continuous spark at the pilot burner. c. Time the spark operation. Time must be within the lockout timing period (15 [...]

SERVICING PROCEDURES TUBE CLEANING PROCEDURE (TYPICAL) Establish a regular inspection schedule, the fre- quency depending on the local water condition and severity of service. Do not let the tubes clog up solidly. Clean out deposits over 1/16" in thickness. Although the illustration shows the mechanical clean- ing procedure of a small boiler, [...]

5. Remove heat exchanger corner brackets. 6. Remove combustion chamber clips at the four corners of the heat exchanger. 7. Lift heat exchanger straight up using caution not to damage refractory.
