5) Smell for gas, including near the floor . If you smell gas, STOP! Follow “B” in the safetyinformation above on this label. If you don’t smell gas, go to the next step.6) Turn on all electric power to the appliance.7) Set thermostat to the desired setting.8) Once the system is lit, inspect the entire installation.9) Make sure the pressure in the boiler is stable.10) Test both 4006A high limits by lowering their set points below the temperature of the boiler one at a time.If either aquastat fails to shut the burner down replace it immediately.11) Simulate a loss of fuel by shutting the oil valve. Once the valve is closed the burner should go into post –purge and then lockout.12) Reset the burner before turning the oil back on to simulate ignition failure. After ignition failure theburner should go through a purge period and then lookout.13) Open the oil valve and return the burner to operation. While the burner is running, trip the breaker at thepanel, that should disable the burner and all other heating controls.14) Once it is determined that the system is operating properly, proceed to tuning up the burner using theproper instruments.

System Start-up Cont.19Recommended procedures for safety inspection of an appliance should be in accordance with theNational Fuel Gas Code, ANSI Z223.1. The following procedure will help evaluate the venting system. It isintended as a guide to aid in determining that the venting system is properly installed and is in a safe conditionfor continuous use. This procedure should be recognized as a generalized procedure which cannot anticipate allsituations. Accordingly, in some cases, deviation from this procedure may be necessary to determine safeoperation of the equipment. If it is determined that a condition exists which could result in unsafe operation,the appliance should be shut off and the owner advised of the unsafe condition. Corrections must be madebefore the appliance is put into continuous operation. The following steps should be followed in making asafety inspection.1. Visually inspect the venting system for proper size and determine that there is noflue gas spillage, blockage, restriction, leakage, corrosion, or other deficiency which could cause anunsafe operation.2. Place in operation the appliance being inspected. Follow the lighting instructions andadjust thermostat so appliance will operate continuously.3. Determine that the burner is operating properly and that the burner ignition operatessatisfactorily by interrupting and re-establishing the electrical power of the appliancein any convenient manner. Test the burner safety device to determine if it is operatingproperly by disconnecting the flame safety circuit.4. Test for smoke spillage at the burner inlet air location around the VRV after 5 minutes of operation. Usea draft gauge, flame of a match or candle, or smoke from a cigarette, cigar or pipe. Shut off appliancethermostat and check for spillage around the VRV. If a flow reversal is noticed, house depressurizationis occurring and make up air is required.Once installation is complete, check the boiler with instruments to ensure that it is working properly.6.
