Hi,

We just tried using our heater and noticed it not kicking on. It's a Raypak P-R407A-EN-C. When I turn it on, I hear a louder click which I guess it he guess valve and then I hear a sparking sound which I believe is it trying to light. I usually smell gas after turning it on. Heater display shows SPK the whole time. I'm not sure where to look to see the pilot light and if it's lit. I'm also unsure what panel to remove to investigate the ignitor as it sounds likes that could have rust or some build up on it.

A few days ago when I was messing with it, the blower kicked on a couple times and then would shut off after 2-3 seconds.

Thoughts?
