I'm just refitting my kitchen and have been told i will need to update the ventilation for my heating.What size lower and higher air vents are required for my Johnson and Starley warm air heating system(GC 42-417-14) into the kitchen, and what size vent will i need from the kitchen to outside (Heating is in the middle of the house)
12.7 Kw heater & 7.9Kw water heater
I will be putting an outside vent behind the kitchen units & a vent into the opposite wall in the kitchen (into the cupboard containing the heater)

you need to tell us the kilowatt input from the data badge,
ie 16kw heater 5.39kw water heater if applicable??????
there is generally badge stuck onto side of heater inside behind grill and if water heater is installed that usually has a metal data badge attached.
how many internal doors will you be venting through
