What Liverpool publishes about boilers, and what half the village is made of

The Village of Liverpool states that it uses the most recent edition of the New York State Uniform Code and that a building permit is required for any work which must conform to the Uniform Code, the Energy Code and the Village Zoning Ordinance. Its published list of such work names installation of any gas lines or appliance including space heaters, and installation of any new or replacement furnace, central air conditioning, boiler, gas fireplace or other heating equipment. The village publishes a separate HVAC Permit Application, Mechanical Permit Application and Heating Appliance and Chimney Application. It states that no person shall commence any work for which a building permit is required without first having obtained one from the Code Official.

Section M1801.3 of the Residential Code of New York State applies where an appliance is permanently disconnected from an existing chimney or vent, or connected to an existing chimney or vent during a new installation. M1801.3.1 requires the chimney or vent to be resized as necessary to control flue gas condensation in its interior and to provide the appliance or appliances served with the required draft, with resizing for oil-fired appliances vented to masonry chimneys done in accordance with NFPA 31. M1801.3.2 requires the flue gas passageway to be free of obstructions and combustible deposits, to be cleaned if previously used for a solid or liquid fuel-burning appliance or fireplace, and the flue liner or inner wall to comply. M1801.3.3 requires a cleanout opening in masonry chimneys and M1801.3.4 sets clearance to combustibles.

Boilers on Liverpool's own list of permitted work
Replacing a boiler usually starts with a fortnight of not knowing whether anyone official is involved. In this village the answer is printed: Liverpool's list of work requiring a building permit names installation of any new or replacement boiler alongside furnaces, central air conditioning and gas fireplaces, and adds any gas line or appliance to the same list. What that buys you is an independent inspection of the work rather than a form for its own sake, and it fixes the order of the job, because the village states that no work may begin until the Code Official has issued the permit. Ask early who is filing and when, because it decides your start date.

What a Liverpool boiler job should settle first
Half of Liverpool was built in 1939 or earlier, 675 of 1,344 units, and that is where the village's radiator housing comes from. In houses of that age the emitters have been added to, removed and boxed in over a century without anyone recording it, so the load the new appliance should answer to is a room by room survey rather than a reading of the old nameplate. The second Liverpool question is the flue: section M1801.3 of the state residential code applies the moment an appliance is disconnected from an existing chimney or connected to one, and requires it to be resized as necessary to control condensation inside and give whatever remains the draft it needs. The village prints a chimney form for exactly this.
Steam or hot water, named in the proposal
In a village half of which predates 1940 both exist, and they differ in piping, controls and venting.
The chimney has its own village form
Liverpool publishes a Heating Appliance and Chimney Application separately from its HVAC and Mechanical forms, which tells you how it views the flue.
A survey of the emitters, not the boiler room
Radiators taken out during kitchen work and added in an extension are the reason the old nameplate is a poor guide in this housing.

Boiler and radiator questions from Liverpool
Does the sizing requirement really reach an old house?
Section M1401.3 of the Residential Code of New York State covers heating and cooling equipment without distinguishing the type, and section R503.1.2 of the state energy code sends new heating systems that are part of an alteration back to the section carrying the Manual S and Manual J requirement. What any particular job has to do is the code official's determination, which is why the village office is the place to ask.
Why does Liverpool print a separate chimney application?
Because the appliance and the flue are two pieces of work. Its Heating Appliance and Chimney Application sits alongside the HVAC and Mechanical forms, and in a village where half the housing predates 1940 that separation is a useful prompt: ask what the plan for the chimney is and whether it is inside the price.
