Tim- My darkroom also houses my hot water tank and furnace. My sink is about 10 feet away from them, and my enlarger/dry side is about 8 feet away. The pilot light is behind the furnace, so it's not in eyesight of my work area, and the glow doesn't reach the work area (that should be a concern for you). It's been like this for 19 years. Haven't blown myself up, yet...
