The boiler should be mounted on a level, non-combustible surface. Boiler must not be installed on carpeting. The boiler can be installed on a combustible surface only when a suitable floor shield base is provided. Raypak offers an optional floor shield base which can be factory installed on all indoor models except Model 133; the Model 133 floor shield base is shipped loose and must be installed by the contractor.
REDUCTION OF CLEARANCES TO PROTECTED SURFACES Note: The boiler shall be installed in a space large in comparison to the size of the boiler. Large space is defined as having a volume at least sixteen (16) times the total volume of the boiler.
These boilers are designed certified for outdoor installation. Boilers must not be installed under an overhang within three (3) feet from the top on the boiler. Three (3) sides must be open in the area under the overhang. Roof water drainage must be diverted away from the boilers with the use of gutters.
VENTING OUTDOOR INSTALLATIONS MODEL 133 Step 1: Remove the front (4) screws. Step 2: Line up outdoor top vent opening over heater vent opening. Step 3: Lower outdoor top onto unit lining up slots in the outdoor top with screws holes in jacket top. Step 4: Reinstall (5) screws to secure jacket top and outdoor top to unit.

WARNING: Do not use thermally actuated vent dampers on a modulating boiler. To do so, may result in asphyxiation. Use only a mechanically actuated vent damper device that is electrically interlocked with the modulating boiler operation.
Check vent damper operation as follows: 1. When the boiler is off, check that the vent damper position indicator points to the closed position. (See figure below.) 2.

We recommend that the pump be sized for 20°F Delta T. (Delta T is the temperature difference between the inlet and outlet water when the boiler is firing at full rate). For some boilers, the Delta T is more than 20°F (22°-33°F) at the recommended flow rates.

MULTIPLE-BOILER– REVERSE RETURN HOOK-UP MODELS 133 TO 4001 Fig. #9495 REVERSE RETURN PIPING IS A PROPER METHOD OF MANIFOLDING MULTIPLE BOILER HOOK-UPS TO ENSURE BALANCED FLOW THROUGH EACH BOILER. VALVES ON SUPPLY AND RETURN ARE NEEDED TO ISOLATE ANY BOILER, AS REQUIRED.
The Raytemp Economaster II is an electronic de- vice that allows the operator to set the desired time for the pump to run after the boiler shuts off. The time is factory-set at 7 minutes and it can be re-adjusted in the field anywhere from 3 to 10 minutes.
Push the reset button and set the limit(s) to 30- 40 °F above desired operating temperature. FLOW SWITCH This dual purpose control shuts off the boiler in the case of a pump failure or low water condition. It is mounted and wired in series to the main gas valve.
National Electrical Code ANSI/NFPA No 70. NOTES: 1. Field install ground to inside of junction box. 2. If any of the original wire as supplied with the boiler must be replaced, it must be replaced with 105°C wire or its equivalent.
BEFORE START-UP Safe lighting and other performance criteria were met with the gas manifold and control assembly pro- vided on the boiler when the boiler underwent tests specified in the latest edition of ANSI-Z21.13 Standard. GENERAL Before lighting up a new installation, water should be flowing through the boiler.
If the pilot will not stay lit after several tries, turn the gas control knob to “OFF” and call your service technician or gas supplier. 10. Stand to the side of the boiler and turn the gas control knob counter-clockwise 11 Replace boiler door panel.
Turn off all electrical power to the appliance. This appliance is equipped with an ignition device which automatically lights the pilot. Do not try to light the pilot by hand. Remove boiler door panel. For Robertshaw gas valve: Turn gas control knob clockwise to “OFF”.
FOR MODELS WITH AUTOMATIC GAS VALVES LIGHTING INSTRUCTIONS 1. Close all gas valves. Turn off electrical power supply. Wait five (5) minutes. 2. Open manual pilot valve. Turn on electrical power. Pilot is automatically lighted. PILOT VALVE CONTROL SHOWN IN THE "ON"...
40°F above desired operating temperature, and push reset button. Burner should light. SUGGESTED INSPECTION SCHEDULE The boiler should be inspected on the first and third months after initial start-up and then on an annual basis. If problems are found, refer to Troubleshooting Guide for additional directions.
Providing pilot is proven, blower will start running, the main gas valve will open and the boiler will operate. When the operating control is satisfied the boiler will shut down.
SERVICE LOW NOx BURNER TRAY ASSEMBLY BURNER TRAY REMOVAL 1. Shut-off main electrical power switch to heater. 2. Shut-off gas upstream of heater. 3. Remove front door. 4. Disconnect gas line from gas valve. 5. Remove (2) screws that mount burner tray to the base of the unit, and (2) screws that secure gas valve to jacket.

When boiler is turned on nothing happens. Thermostat in "ON" position causes relay and pump to operate, but boiler does not fire. Continuous shut down of manual reset high limit. Sooting CAUTION-Soot may be combustible. Wet down and exercise caution when cleaning.
Do not let the tubes clog up solidly. Clean out deposits over 1/16" in thickness. The boiler may be cleaned from the side opposite the water connections as shown, without breaking pipe connections. It is preferable, however, to remove both PUMP LOSES PRIME 1.
BURNER TRAY REMOVAL 1. Shut-off power and gas supply to the boiler. Disconnect union(s) and pilot tubing, then loosen and remove burner hold-down screws. 2. Disconnect wires at gas valve and slide burner tray out. GAS VALVE REMOVAL 1. Shut-off gas supply to the boiler. Remove gas piping to gas valve inlet.
7. Open water supply and return shut-off valves. Fill boiler and water piping system with water. Check boiler and piping system for leaks at full line pres- sure. Run system circulating pump for a minimum of 1/2 hour with boiler off.
Any part returned for replacement under standard company warranties must be properly tagged with Raypak return parts tag, completely filled in with the heater serial number, model number, etc., and shipped to Raypak freight prepaid. If determined defective by Raypak and within war- ranty, the part will be returned in kind or equal substi- tution, freight collect.
