Takes well over 30 min to get the full glow going. If you have a draft, like the door open it may not get into full glow.
The 2nd flashover is important, like "HVAC" Fred said.
Remember this is a radiant heat heater. It takes a while to get things warmed up. It does not warm the air, the objects that the radiant heat hits is what warms up the rig.
A furnace relies on heated air to warm up things.
When we want to warm up fast we use the furnace for 1 or 2 cycles and have the wave fired up....
If you are not able to get full glow going I would contact the mfg by phone... They are great folks.. The unit could be defective or your propane pressure is a bit low.
