4 Fig. #8245 CLEARANCES ALL HEATERS For clearances from combustible surfaces, see chart below. We require a minimal vertical clearance of three feet between the upper surface of the flue outlet to a non- combustible material.
5' MIN 2' MIN 10' OR LESS 2' MIN VENT CAP VENT PIPE DRAFT HOOD HEA TER For protection against rain or blockage by snow, the vent pipe must terminate with a vent cap which complies with the local codes or, in the absence of such codes, to the latest edition of the National Fuel Gas Code, ANSI Z223.
(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.
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.
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.

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.
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.

14 EXTERNAL AUXILIARY BYPASS VALVE (Where Required) 926-1223 Models only An auxiliary bypass valve should be used when flow rates exceed 120 GPM (usually a high performance pump size larger than two HP will exceed this flow rate).
15 HIGH & LOW GAS PRESSURE SWITCHES Pressure switches sense either high or low gas pressure and automatically shut down burners if abnor- mal pressures exsist. Standard on Models 3001-4001.

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.

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.
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.
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. HEAT EXCHANGER REASSEMBLY 1. Heat exchanger header O-rings should be replaced with new ones.
CONTROL WELL REPLACEMENT Remove top, sensing bulb and clip. Collapse well tube at the open end and with a chisel, push through into the header, and remove the well through header. Insert a new well and roll into place. If a roller is not available, solder the well in place with silver solder.
