My raypak rp2100 electronic seems to light the pilot light but then it takes a while to light the gas and when it does it shoots flames out the top of the heater. I'm thinking its the gas valve or the ignition. Help

It is probably something much more simple than that...Turn it on and stand back until it finally ignites, then look, using a mirror, at the burner tray from below. You will probably find a lot of the tubes, especially those near the pilot area, are not working or are burning bright orange. If that is the case, something, probably spiders, are blocking the gas from getting into the tubes. That will cause the big burst at ignition as the gas builds up for a bit before it finally reaches the pilot area.
Raypak Rp2100 lights and heats until burner turns off, but heat light remains lit. Heater does not restart. Plenty of water flow, any ideas.
