IX. Service

DANGER

This boiler uses flammable gas, high voltage electricity, moving parts, and very hot water under high pressure. Assure that all gas and electric power supplies are off and that the water temperature is cool before attempting any disassembly or service.

Do not attempt any service work if gas is present in the air in the vicinity of the boiler. Never modify, remove or tamper with any control device.

WARNING

This boiler must only be serviced and repaired by skilled and experienced service technicians.

If any controls are replaced, they must be replaced with identical models.

Read, understand and follow all the instructions and warnings contained in all the sections of this manual.

If any electrical wires are disconnected during service, clearly label the wires and assure that the wires are reconnected properly.

Never jump out or bypass any safety or operating control or component of this boiler.

Read, understand and follow all the instructions and warnings contained in ALL of the component instruction manuals.

Assure that all safety and operating controls and components are operating properly before placing the boiler back in service.

A.General. Inspection and service should be conducted annually. Turn off electrical power and gas supply while conducting service or maintenance. Follow instructions TO TURN OFF GAS TO APPLIANCE. See Figure 22.

B.Low water cutoff (if so equipped).

Probe Type (Annual Service). Probe type LWCO should be removed once a year, examined and cleaned of any dirt accumulations to assure proper operations. Do not attempt to repair mechanisms in the field. Complete replacement mechanisms, including necessary gaskets and installation instructions, are available from the manufacturer.

C.Vent System. Inspect for obstructions, soot accumulation, proper support, and deterioration of pipe, fittings, and joints.

1.Clean terminal screens. Terminals must be free of obstruction, undamaged, with screens securely in place.

2.Terminal and wall thimbles (if used) must be weathertight.

3.Pipe must be full round shape, and show no damage from impact or excessive temperature.

4.Pipe must be supported at minimum five (5) foot intervals and must not sag.

5.All vent joints must be secure and watertight.

6.All joints must be secure and airtight. Horizontal vent tee drain or vertical vent tee drain (if used) must have minimum 6 inch trap and allow condensate to flow freely. To Clean:

a.Disconnect drain tube from drain fitting.

b.Flush drain tube with water. Fill trap with water.

c.Securely fasten drain tube to drain fitting, providing gas-tight and watertight seal.

7.If pipe must be disassembled for removal of obstructions or resealing of joint, see Section III, Paragraph C.

D.Boiler Flue Passages. Inspect for blockage or soot accumulation.

1.Remove Main Burners. See Figure 30.

a.Remove front door.

b.Disconnect pilot tubing and pilot lead wires at the gas valve.

c.Remove wires to Flame Roll-out Switch.

d.Remove Burner Access Panel.

PVG specifications

Burnham PVG, an innovative leader in the heating industry, presents a range of high-efficiency gas boilers that are designed specifically for residential applications. Burnham has established a solid reputation for producing reliable and durable heating solutions, with the PVG series exemplifying their commitment to quality and performance.

One of the standout features of the Burnham PVG is its advanced stainless steel heat exchanger. This design not only ensures superior heat transfer but also enhances durability and resistance to corrosion compared to traditional cast iron counterparts. The use of stainless steel contributes to the longevity of the system, allowing homeowners to enjoy efficient heating for years with less risk of breakdown.

The PVG series incorporates cutting-edge modulating technology, which adjusts the boiler’s output to match the heating demand. This modulating feature allows for more precise temperature control, optimizing energy consumption and minimizing fuel costs. Unlike conventional boilers that operate at a fixed output, the ability to modulate enables the PVG to deliver precisely the right amount of energy when needed, thus enhancing overall system efficiency.

In addition to its efficiency and performance capabilities, the Burnham PVG is designed with ease of installation and maintenance in mind. The compact design enables versatile installation options, even in tight spaces or retrofit applications. Furthermore, the accessible panel layout simplifies service and maintenance tasks, allowing HVAC professionals to perform routine checks and repairs with ease.

The PVG series also emphasizes user-friendly operations, featuring intuitive controls that allow for straightforward adjustments and monitoring. With options for direct vent and conventional venting systems, homeowners can select the best installation method for their specific needs and living environment.

Additionally, the Burnham PVG aligns with environmental considerations by meeting stringent emissions standards, contributing to reduced greenhouse gas outputs. With its energy-efficient operation and commitment to sustainability, the PVG series represents a forward-thinking choice for those looking to reduce their carbon footprint while enhancing home comfort.

In summary, Burnham PVG is characterized by its durable stainless steel construction, modulating technology, compact design, user-friendly controls, and eco-conscious performance. This series exemplifies what modern residential heating solutions should aspire to achieve: efficiency, reliability, and sustainability, making it an excellent choice for intelligent energy management in the home.
