Outdoor Water Heaters These heaters are design certified for outdoor installa- tion. Heaters must not be installed under an overhang of less than three (3) feet from the top on the heater. Three (3) sides must be open in the area under the overhang.
NOTE: If louvers, grills or screens are used on the openings, obtain the net free area from their suppli- er or manufacturer. If the design free area of a louver is not known nor available, it shall be assumed that wood louvers will have 20-25 percent free area and metal louvers will have 60-75 percent free area as specified in the National Fuel Gas Code.

If originally installed, remove "Pagoda" top from the louvered jacket top. 3. Place the inner stack adapter panel over the flue collector inside the heater.
Vent Piping WARNING: Indoor heaters require a drafthood that must be connected to a vent pipe and properly vented to the outside. Failure to follow this procedure can cause fire or fatal carbon monoxide poisoning. Vent piping of the same size as the drafthood outlet is recommended, however, when the total vent height is at least ten (10) feet (drafthood relief opening to vent terminal), the vent pipe size may be reduced as spec-...
Code, ANSI Z223.1. For special venting applications that require reduced vent sizes and through-the-wall venting, the Type D Induced Draft Assembly can be used. Consult the fac- tory or your local Raypak representative. Vent Damper Installation Models 0133 Through 0180 (Where Required)

on-off cycling heater. The valve has a remote capillary bulb immersed in a well, at the header outlet, to main- tain a constant outlet water temperature. When multiple valves are furnished, they can be staged to give greater flexibility of control. Standard factory set- ting is at position 5.
100% Pilot Safety Models 0514-4001 employ electronic devices which close the main gas valve within 8/10 of a second whenever the pilot flame is interrupted. Pilot flame is automatically lit when the device is powered. Unit per- forms its own safety check and opens the main valve only after the pilot is proven to be lit.

LIGHTING INSTRUCTIONS FOR HEATERS WITH ELECTRONIC IGNITION (IID) FOR MODELS WITH MANUAL GAS VALVES FOR YOUR SAFETY READ BEFORE OPERATING WARNING:If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. This appliance is equipped with an ignition device which automatically lights the pilot.
FOR MODELS WITH AUTOMATIC GAS VALVES 1. Close all gas valves. Turn off electric power supply. Wait five (5) minutes. 2. Open manual pilot valve. Turn on electric power. Pilot is automatically lighted. 3. Open main gas valve. 4. Set temperature controls to desired temperature. TO SHUT DOWN Close all manual gas valves.
Inspection Procedures Inspect on the first and third month after initial startup and then on an annual basis. If problems are found, refer to the Troubleshooting sections of this manual for additional directions. 1. Remove top of heater and inspect heat exchanger for soot and examine venting system.
c. Check the ignition spark operation. Time must be within the lockout timing period (15 or 90 sec- onds). d. Turn control down to end call for heat and wait 60 seconds on lockout models before beginning step 3. 3. Turn on gas supply. 4.
Main burner And Orifice Removal 1. Remove burner tray. (See Burner Tray Removal procedure on page 34.) 2. Remove (8) screws from the hold-down brackets. 3. Remove (8) screws from the left and right sides of the manifold assembly. Detach the manifold assembly from the burner tray assembly.
