Just got the issue through
Think this guy was trying to hurt someone,could have been trying to become a serial killer !
Out of 150 of his boiler installations checked,47 were found classed as 'at risk',immediately dangerous',or reportable under riddor !!
Anyone who has run a boiler with the flue not connected,will know you can tell straightaway by the noise and you would sense the fumes almost straight away
Think there are mental issues here,as said ,think he was trying to hurt someone,5 years is a joke,taking above into account
imho
Mr Ellis... rest in peace and sincere condolences to family and friends
