New Yorker Boiler Parts

New Yorker Boiler parts are manufacturer-specific replacement components designed for New Yorker cast iron boilers, including the CG, PVCG, CGS, CL, AP-U, and FR series. New Yorker Boiler parts cover everything a heating contractor needs to service or restore these units to full operation, from ignition controls and boiler controls to canopy assemblies, pressure relief valves, combustion chamber liners, and burner components. New Yorker cast iron heat exchangers are built with metal or cast iron section connectors that resist petroleum-based chemicals, including antifreeze, which can deteriorate the rubber seals found in competing designs. Getting the right part starts with the model number on the unit's rating label, because New Yorker runs multiple series with distinct component specs. For a contractor servicing the New York metro area or any cold-climate market, knowing which parts fit which series is not optional. It is the difference between a same-day restore and a heating system down for days.

KEY SUBCATEGORIES / PRODUCT TYPES

Boiler Controls

A boiler control is the integrated electronic component that consolidates high-limit switching, circulator relay function, and electronic ignition into a single module. On New Yorker CG and PVCG series units, the boiler control also manages an energy-saving thermal purge sequence, circulating residual warm water through the heating system before firing the burner to extract every usable BTU from the previous cycle. The New Yorker boiler control replacement part number 106541-01 is a verified replacement component for applicable CG and PVCG models. When a boiler control fails, the unit may go into hard lockout, display status codes, or fail to advance through its ignition sequence, all of which are diagnostics a technician reads directly from the control's LED indicator. Replacing the control on the correct model is straightforward, but confirming compatibility against the unit's model number and rating label is a required first step before ordering.

Canopy Assemblies

A canopy assembly is the sheet metal top cap that seals the boiler section stack and connects to the flue collar, directing combustion gases toward the vent or chimney. On New Yorker CL series oil boilers, the canopy assembly for 3-section units with a 5-7/8-inch diameter collar carries part number 104585-03. Canopy assemblies must match the section count of the boiler, since 3-section and larger configurations use different collar dimensions. A failed or damaged canopy can allow flue gas to escape into the boiler room rather than exhaust properly, making it a replacement that cannot wait for the next scheduled maintenance visit. Always cross-reference section count and collar diameter against New Yorker service documentation for the specific model before ordering.

Pressure Relief Valves

A pressure relief valve is the primary safety device that prevents a hot water boiler from exceeding its maximum allowable working pressure. On New Yorker CL series residential hot water boilers, the factory-standard pressure relief valve is rated at 30 PSI, corresponding to part number 81660319. Steam boilers in the CL series use a different valve rated at 15 PSI, part number 81660530, because steam systems operate at significantly lower pressures than hot water systems. Mixing up a 30 PSI hot water valve with a 15 PSI steam valve is the kind of error that creates a dangerous condition rather than fixing one. Always confirm whether the system is a hot water or steam configuration before specifying a replacement pressure relief valve.

Combustion Chamber Liners

A combustion chamber liner is the refractory or insulating material that lines the interior firebox, protecting the cast iron sections from direct flame contact and maintaining the combustion geometry required for efficient burner operation. On New Yorker CL series oil boilers, the installation manual explicitly warns that if the combustion chamber liner is damaged during cleaning or service, it must be replaced immediately. A deteriorated liner can allow flame impingement on the cast iron sections, reduce combustion efficiency, and lead to carbon monoxide production if the burn geometry is distorted. New Yorker CL series liner components are referenced by section count, so a 3-section boiler uses a liner sized for a 3-section configuration. Verify against New Yorker's parts documentation for the specific model and section count before specifying a replacement.

Pilot and Ignition Components

Pilot assemblies, ignition cables, ceramic insulators, and spark gap components are the wear items most likely to require replacement during annual service on New Yorker CG and CGS series gas-fired units. New Yorker's installation documentation specifies checking the ignition cable boot for signs of melting or buckling, inspecting the ceramic insulator, and verifying the spark gap as part of standard service procedure. On intermittent ignition (EI) models, a failed pilot assembly or sensor can prevent the control from proving flame, pushing the unit into lockout without firing the main burners. Pilot assembly replacement on CG series units requires removing the main burner with the pilot, making it a straightforward field repair when the correct replacement assembly is on hand. Flame current should read within spec after any pilot component replacement, confirmed with a micro-ammeter per New Yorker service documentation.

BUYING GUIDE / HOW TO CHOOSE

Specifying New Yorker Boiler parts correctly starts with the unit's model number and serial number from the rating label on the boiler jacket. New Yorker runs multiple series, each with distinct component configurations, and a part that fits a CG series gas-fired water boiler may not be compatible with a CGS series steam boiler or a CL series oil boiler.

The first decision variable is boiler type: gas-fired or oil-fired, and water or steam. Pressure relief valves alone illustrate the stakes here. Residential hot water boilers in the CL series use a 30 PSI valve, while steam boilers in the same CL series use a 15 PSI valve. Installing the wrong rating is a safety issue, not just a performance issue.

For boiler controls on New Yorker PVCG and CG series gas-fired units, replacement part 106541-01 fits applicable models, but confirming compatibility against the specific model number is mandatory before ordering. The integrated boiler control on PVCG-C series units consolidates high-limit control, circulator relay, and electronic ignition into a single module, including the thermal purge feature. Replacing the wrong control can disrupt that entire sequence.

Section count matters for structural components. Canopy assemblies and combustion chamber liners on the CL oil boiler series are sized by section count. The 3-section CL boiler uses a canopy with a 5-7/8-inch diameter collar, part number 104585-03. A 4-section or 5-section boiler uses a different canopy. Getting section count wrong means the part does not fit.

To find the right New Yorker Boiler parts, the model number finder on SupplyHouse's boiler parts tool identifies which parts list applies to each unit. Clicking through by model number pulls the complete parts list for that specific New Yorker boiler. If the model number is not available, a part request form connects with the parts team for assistance. Photographing the rating label before the service call is worth the 10 seconds it takes.

FAQs

What New Yorker Boiler parts are needed for annual service?

Annual service on New Yorker gas-fired boilers typically involves inspecting and potentially replacing pilot assemblies, ignition cables, ceramic insulators, and burner orifices, as these are the components New Yorker's own installation and service documentation identifies as part of the yearly maintenance sequence. On CG and PVCG series units, the technician should also inspect the boiler control's LED status indicators, check the vent damper operation, and verify the high-limit setpoint. For CL series oil boilers, the combustion chamber liner and combustion target wall should be inspected at every annual service, and the liner should be replaced immediately if damaged rather than deferred to a future visit.

How do New Yorker PVCG series parts differ from CG series parts?

The difference between New Yorker PVCG series parts and CG series parts is primarily in the boiler control module and venting components, as PVCG series boilers are power-vented units that vent through the wall while CG series boilers use a traditional draft hood and chimney vent configuration. The PVCG-C series includes an integrated boiler control that combines high-limit, circulator relay, electronic ignition, and thermal purge into a single module, whereas earlier CG series configurations used separate components for some of those functions. Part numbers for controls, vent adapters, and pressure switches do not cross between the PVCG and CG series without confirming compatibility from New Yorker's engineering documentation first. Always use the model number from the rating label when sourcing replacement parts for any New Yorker boiler series.

What is the correct pressure relief valve for a New Yorker CL series boiler?

The correct pressure relief valve for a New Yorker CL series hot water boiler is rated at 30 PSI, corresponding to part number 81660319. New Yorker CL series steam boilers require a different pressure relief valve rated at 15 PSI, part number 81660530, because steam systems operate at much lower working pressures than hot water systems. Mismatching pressure ratings can result in either a valve that never relieves when it should or one that relieves constantly under normal operating pressure, both of which can create unsafe or unreliable operating conditions. Confirm whether the system is a hot water or steam configuration before specifying a replacement pressure relief valve.

How does the thermal purge feature on New Yorker PVCG-C series boilers work, and which parts support it?

The thermal purge feature on New Yorker PVCG-C series boilers works by circulating residual warm water through the heating system prior to firing the burner, extracting heat already in the boiler rather than firing immediately on a thermostat call. The integrated boiler control module manages this sequence, meaning the boiler control is the primary component to service or replace when thermal purge behavior is abnormal. Replacement boiler control part 106541-01 is the applicable module for CG and PVCG series units where confirmed compatible with the model number. Always cycle power to the control and consult New Yorker's troubleshooting documentation before replacing the control module, as fault codes displayed by the LED can narrow the diagnosis significantly.

Which New Yorker Boiler parts require section count confirmation before ordering?

New Yorker Boiler parts that require section count confirmation before ordering include canopy assemblies, combustion chamber liners, and section gaskets, as these components are sized to match the specific number of cast iron sections in the boiler. The 3-section CL series oil boiler uses a canopy assembly with a 5-7/8-inch diameter collar, part number 104585-03, which does not apply to 4-section or larger configurations. Getting the section count from the unit's model number or rating label before placing an order for structural boiler components can prevent a return and keep the job on schedule. New Yorker's model numbering convention typically encodes section count directly in the model designation for CL series units.
