Unless you have an auto/manual-changeover regulator that swaps from empty to full duel cylinders, then any disconnection of the cylinder will introduce air into the system, that needs to be bled out before appliances function normally.
It can take a little while to bleed the system AND the particular branch pipe to the appliance! Common practice to bleed the general system is to light a cooker burner, firstly this is a high demand outlet and purges the system quickly, and you can easily see when it's working right. Things like heaters and ovens etc. protected by thermocouple 'flame out' devices often have very low flames initially until the thermocouple heats up (equalling very low gas flow, and consequent slow air purging!), this can mean it takes a little longer to purge the pipes and they will often struggle to light/stay alight initially.
The above method is a cost free way of checking if air in the system is the problem, otherwise you're into actual fault-finding on the appliance.
