IF THE UNIT IS EXPOSED TO THE FOLLOWING, DO NOT OPERATE HEATER UNTIL ALL CORRECTIVE STEPS HAVE BEEN MADE BY A QUALIFIED SERVICEMAN. 1. EXTERNAL FIRE. 2. DAMAGE. 3. FIRING WITHOUT WATER. 4. SOOTING CHEMICAL VAPOR CORROSION WARNING CORROSION OF THE FLUEWAYS AND VENT SYSTEM MAY OCCUR IF AIR FOR COMBUSTION CONTAINS CERTAIN CHEMICAL VAPORS.
IMPROPER AND INEFFICIENT OPERATION OF THE APPLIANCE RESULTING IN THE PRODUCTION OF INCREASED LEVELS OF CARBON MONOXIDE GAS IN EXCESS OF SAFE LIMITS WHICH COULD RESULT IN SERIOUS PERSONAL INJURY OR DEATH. You should contact your gas supplier for any specific changes which may be required in your area.
Continued pilot outage preceded by higher than usual water temperature is evidence of high limit switch operation. Contact your dealer or servicer to determine the reason for operation. ELECTRONIC IGNITION CONTROL Each heater is equipped with a Honeywell ignition module. The solid state ignition control, fig.
WARNING THERE IS A RISK IN USING FUEL BURNING APPLIANCES SUCH AS GAS WATER HEATERS IN ROOMS, GARAGES OR OTHER AREAS WHERE GASOLINE, OTHER FLAMMABLE LIQUIDS OR ENGINE DRIVEN EQUIPMENT OR VEHICLES ARE STORED, OPERATED OR REPAIRED. FLAMMABLE VAPORS ARE HEAVY AND TRAVEL ALONG THE FLOOR AND MAY BE IGNITED BY THE HEATER’S PILOT OR MAIN BURNER FLAMES CAUSING FIRE OR EXPLOSION.
ILLUSTRATION OF MINIMUM COMBUSTIBLE CLEARANCES IN AN ALCOVE HARD WATER Where hard water conditions exist, water softening or the threshold type of water treatment is recommended. This will protect the dishwashers, coffee urns, water heaters, water piping and other equipment. See MAINTENANCE section for details of tank cleanout procedure.
VENTING WARNING THE INSTRUCTIONS IN THIS SECTION ON VENTING MUST BE FOLLOWED TO AVOID CHOKED COMBUSTION OR RECIRCULATION OF FLUE GASES. CAUSE SOOTING OR RISKS OF FIRE AND ASPHYXIATION. Heater must be protected from freezing downdrafts. Remove all soot or other obstructions from the chimney that will retard a free draft.

ASME ratings cover pressure relief capacities. A.G.A. ratings cover release rate with temperature actuation. In addition to the appliance relief valve, each remote storage tank which may be used in conjunction with this appliance shall also be installed with a properly sized, rated and approved combination temperature (ANSI) and pressure (ASME) relief valve(s).
DISCONNECT THE HEATER AND ITS MANUAL GAS SHUTOFF VALVE FROM THE GAS SUPPLY PIPING SYSTEM DURING ANY SUPPLY PRESSURE TESTING EXCEEDING 1/2 PSIG (3.45 Kpa). GAS SUPPLY LINE MUST BE CAPPED WHEN DISCONNECTED FROM THE HEATER FOR TEST PRESSURES OF 1/2 PSIG (3.45 Kpa) OR LESS. THE APPLIANCE NEED NOT BE DISCONNECTED, BUT MUST BE ISOLATED FROM THE SUPPLY PRESSURE TEST BY CLOSING THE MANUAL GAS SHUTOFF VALVE.
For Canadian installations the electrical connections and grounding shall be done in accordance with current Canadian Electrical Code CSA C22.1, Part 1 and/or local codes. INSTALLATION DIAGRAMS-TOP INLET/OUTLET USAGE GENERAL The type, size and location of the relief valves must be in accordance with local codes.

ADJUSTMENTS ON INITIAL STARTUP SOME ADJUSTMENTS ARE NECESSARY. 1. CHECK MANIFOLD AND INLET GAS PRESSURES. 2. TO ADJUST PILOT FLAME - FOLLOW “PILOT BURNER” PROCEDURE UNDER “PREVENTIVE MAINTENANCE”. WATER TEMPERATURE CONTROL WARNING THIS WATER HEATER IS EQUIPPED WITH AN ADJUSTABLE THERMOSTAT TO CONTROL WATER TEMPERATURE.
1. Seal any unused openings in the venting system. 2. Inspect the venting system for proper size and horizontal pitch, as required in the National Fuel Gas Code, ANSI Z223.1 or the CAN/CGA B149 Installation codes and these instructions. Determine that there is no blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition.
TYPICAL PILOT AND MAIN BURNER FLAMES FIGURE 16 If the preceding burner characteristics are not evident, check for accumulation of lint or other foreign material that restricts or blocks the air openings to the burner or heater. NOTE: Cleaning of main burners. 1.
VENTING SYSTEM Examine the venting system every six months for obstructions and/or deterioration of the vent piping. Remove all soot or other obstructions from chimney which will retard free draft. REMOTE STORAGE TANK TEMPERATURE CONTROL The water temperature in the storage tank (if used) is controlled by the storage tank temperature control.
UN•LIME and the booklet may be obtained through your State ® dealer or distributor. FIGURE 18 DELIMING SOLVENTS State recommends the use of UN•LIME for deliming. UN•LIME is a patented food grade acid which is safe to handle and does not create the harmful fumes which are associated with other products.
1. With the 5 gallon Up-N-Down container in the vertical position, unscrew the plastic vent cap in the handle and pierce the plastic membrane over the vent boss under the cap to allow the container to vent. Note: If your container does not have the vent cap and vent boss, drill a 3/16"...
EFFIKAL RVGP-KSF-SERIES FLUE DAMPER TROUBLE SHOOTING GUIDE Do not turn damper open manually or motor damage will result, use the service switch. All readings are taken from harness receptacle. Do not push meter leads into harness receptacle. This opens the pins and will create connection problems. NOTE: DAMPER DISC SHOWN IN OPEN POSITION.
This checklist in conjunction with “TROUBLESHOOTING” and the “SEQUENCE OF OPERATION” should be used as an on-the-job troubleshooting guide to identify the cause of incorrect system operation and suggest a remedy for its correction. Because improper piping and wiring can result in unsatisfactory system performance, it is suggested that the installation by examined before using the checklist.
