Observe the clearances associated with the class of vent pipe used. FIGURE H Installation - Electrical 1. Route the control cable from the power venter fan along the ceiling or joists down to the gas pressure switch, taking care not to come closer than 6" to the vent pipe or any other potentially hot surface. In many cases, the gas supply piping can be used as a routing path from the ceiling down to the controls, using the supplied nylon ties to secure the cable. 2. Connect the BLUE wire from the jacketed power vent cable onto the normally open terminal of the gas pressure switch. (See Figure I) 8 FIGURE I 3. Connect the RED wire from the jacketed cable onto the common terminal of the gas pressure switch. (See Figure I) NOTE: If the distance between the power venter and the gas pressure switch is greater than the length of the cable, splice a section of 2 conductor, PVC sheathed, 105. C thermostat cable to the supplied cable. Make sure that the colored leads remain consistent. TROUBLE-SHOOTING, MAINTENANCE AND TEST PROCEDURES Vent System Maintenance The vent system must be inspected at regular 3 month intervals. Points of inspection are as follows: 1. Screened opening of the vent hood should be free from foreign material and cleaned as necessary. 2. Check all vent system connections for leakage and reseal where needed. If any vent pipe shows signs of deterioration, replace immediately and check new connections for possible leaks. Reseal using RTV Red HiTemp Silicone Sealer or equivalent. Inspect proper closure of the back draft flapper accessory, if used, and correct if it does not close properly after use. Gas Pressure Switch Test 1. Follow the water heater operating instructions to light the pilot / operate the heater. 2. Open a hot water outlet. This should energize the power vent system. Next close the hot water outlet to de-energize the venter. 3. Repeat step 2 to assure proper operation. 4. If power venter does not energize, check that the gas pressure switch tubes are properly connected and that the tube ends are not pinched closed. 5. Make sure pressure switch is mounted in such a way that the diaphragm is oriented vertically. Combustion Air Test 1. Close all doors and windows of the building. If the water heater is installed in a utility room or closet, close the entrance door to this room. Close fireplace dampers. 2. Turn on any clothes dryers. Turn on all exhaust fans, such as a range hood, bath room exhaust fans and whole house fans, to maximum speeds. (Do not turn on any fans used strictly for summer exhausting). 3. Open a hot water tap to full flow. 4. Allow all fans and the water heater to operate for five (5) minutes. 5. Tripping of the spillage switch circuit (resulting in shut down of the heater) during the 5 minute operation indicates an unsafe operating condition. Turn off gas supply to water heater and DO NOT OPERATE UNTIL UNSAFE VENTING CONDITION IS INVESTIGATED BY A PROFESSIONAL CONTRACTOR OR UTILITY SERVICE PERSONNEL. 6. Return all windows, doors and fans to their previous condition of use. 9 SAFETY INTERLOCK TEST 1. Open the gas supply to the water heater. 2. Remove the vent pipe from the vent connector on the top of the water heater. 3. Block the vent connector with sheet metal or other noncombustible material. 4. Turn on the hot water supply to allow the burner to activate. Hot flue gasses will spill from the draft diverter momentarily. In less than three (3) minutes, the linear spillage switch should trip, opening the electric circuit to the electromagnet valve and halting the flow of gas to the burner. NOTE: If spillage switch does not shut off the gas, check that you have made the proper safety circuit connections. If the switch still does not trip, contact Controlled Energy Corporation at 800 642 3111. NOTE: Models with built in flue gas sensors (mounted on draft diverter) may cut out operation of the heater before the spillage switch does. This is not an error of the spillage switch. 5. After the burners shut off, turn off hot water supply and wait 2-3 minutes...then push the reset button on the linear spillage switch. 6. Light pilot or operate heater and repeat Safety Interlock Test, (Step 1-5) 7. Reconnect the vent pipe to the venting system when complete. CAUTION: Metal vent pipe and vent blockage metal will be hot. In the Event of Pilot/Burner Outage 1. Push the reset button located in the center of the linear spillage sensing switch. 2. Verify that there is 115V power provided to the Power Venter. This can be done by checking the circuit breaker and electrical connections. 3. Visually verify that all the connections of the control cord circuit are intact. 4. Follow heater installation and operating instructions for relighting the heater. 5. Perform the operation circuit test and safety circuit check. (See Safety Interlock Test) TROUBLESHOOTING THE POWER VENTER 1. Fan Motor runs all the time: Make sure the pressure tube that connects to the heater is properly connected to...
