Re: Emergency switch
As Bob said it is always a local code requirement. This is also a uniquely Northeastern issue due to the prevalence of oil heat.
I was curious about this myself and discovered that the codes in some New England states require the emergency switch and Firomatic (thermal cutoff) for
oil burning equipment only because of the special hazards that oil burners present.
Nontheless, this hasn't prevented inspectors from overstepping their authority and requiring them for
everything . :roll:
As such, EC's follow suit and just install the remote switches for all types of heating systems: gas, propane, and oil.
