How Much Heat Do You Need?
You can calculate the amount of BTUs required by using the following method: Measure the space’s dimension to determine cubic feet. (Length x Width x Height = Cubic Feet). Subtract the outside temperature from the desired inside temperature to determine the temperature increase. If you have measured temperature in Fahrenheit, calculate the required BTUs with this formula: (Cubic Feet x Temperature Increase x .133 = Required BTUs) If you have measured temperature in Celsius, calculate the required BTUs with this formula: (Cubic Feet x Temperature Increase x .2394 = Required BTUs).

EDIT: OK, the failure mode is not in the design but the manufacturing. Open up the heater and everything was loose. The brass nut on the main valve was complete off. Hence the not lighting problem. There are also, two screws (M4) opposite the tilt mechanism, one missing, one loose. entire head would move back and forth. Replaced the missing screw, tightened everything and it now lights easy! Tilt safety functions properly.
Oh, final note, while you have it apart, grind of the ON button and sand smooth, your thumb will love you.
