Have a Hayward 150 natural gas, pilot will light but the flame is very large, not a typical pilot flame? I have a clicker lighter that wire broke so lit it manually, did same thing last year was fine? Any ideas what would cause flame to be so big?
Could be a couple of things...The pilot orifice could have gotten larger somehow. The line gas pressure is too high. Maybe trying to overcome a too small pipe. The gas valve may be out of adjustment somehow. You need to have someone come in and measure the water column on the gas line to verify
