First check to make sure the isolating valve on the fridge
is open or any other valve on the line going to fridge
I know in my Boler
camper when I first turn on the gas, I will bleed the line the gas lines by lighting
the gas stove, this is right over the fridge.
Even after bleeding the line to the stove the short tee line going to the fridge will take about 6 tries before gas will finally get there.
be careful and if you smell any gas and it doesn't light
check to see if pizzo is working. before turning gas on open inspection flap and hit Pizzo to see if it sparks.
Follow instructions on lighting
