I have a 6KW multi-fuel stove with ordinary multifuel liner. I am having
some work doing on the front of the house and I thought it might be
time to ensure that the stove has the correct amount of air supply
(according to the regs that is - its a draughty old cottage so
pragmatically...).

Table 2.1 in Part J says...

"Other appliance, such as a stove, cooker or
boiler, with no flue draught stabiliser."

needs

"A permanent air entry opening or openings with a total free area of at
least 550mm2 per kW of appliance rated output above 5kW."

This is 5.5cm2 in my case ... am I getting this right as it seems miniscule?

TIA,

Alex.
