Model G3B Gas burner — Instruction manualMNG3B Gas 041015145. Perform Checkout Procedures • Fill Out CertificateMake final burner adjustmentsCheck for leaks in gas piping❏ Smell around burner to make sure there is no gas leak in near-burnerpiping. Verify integrity of gas line joints between combination gasvalve and burner gas inlet tapping using soap suds mixture. Verifygas piping is fully supported, independently of burner.Check for leaks from burner components❏ Smell around burner to make sure there is no leakage from the burnerinlet air tube, blower housing or air tube. Verify burner is properlysupported and flange is securely tightened.If you detect leakage from any burner component, immediatelyclose the main manual gas valve. Use a soap suds mixture todetermine leakage location. Replace burner if leakage cannotbe corrected by properly securing components. You may haveto restart the burner several times during leakage testingsince the control will lockout when flame is not detected.Failure to correct leakage problems could result in severepersonal injury, death or substantial property damage.Check/adjust gas valve outlet pressure❏ With burner running, check manometer reading for combination gasvalve outlet pressure. Adjust valve regulator if necessary so thereading is 3.5 inches w.c. for either natural gas or propane gas.Inspect flame❏ Look at flame through appliance observation port. The flame shouldbe a soft blue with well-defined orange and yellow tips for naturalgas, or well-defined yellow tips for propane gas. (If you make air orgas pressure changes later, inspect the flame again.)Check the firing rate❏ Natural gas only — Turn off all other gas appliances connected tothe gas meter. Use a stopwatch to time the number of seconds for aflow of one cubic foot of gas (two revolutions for a one half cubic footper revolution dial, for example). You will also need to know the gasheat content in Btu per cubic foot. Determine the actual input from:INPUT = (3600 x Btu per cubic foot) ÷ (number of seconds for one cubicfoot), for firing rate in Btuh. For example, for 1050 Btu per cubic footnatural gas, with meter timed at 30.2 seconds for one cubic foot ofgas: INPUT example = (3600 x 1050) ÷ (30.2) = 125,200 Btuh. Firingrate should be within ± 5% of rated input for the appliance. Adjustthe combination gas valve pressure regulator if necessary to obtainthe correct firing rate. Valve outlet pressure must not be lower than3.2 inches w.c. nor higher than 3.8 inches w.c.❏ For propane gas, contact your propane supply for procedure to verifyfiring rate.Make final burner adjustments (continued) |
