CONNECTING TO GAS SUPPLY

NOTICE

A qualified service person must connect heater to gas supply. Follow all local codes.

WARNING

Never connect heater to private (non-utility) gas wells. This gas is commonly known as well-head gas.

IMPORTANT: Check gas line pressure before connecting heater to gas line. Gas line pressure must be no greater than 14 inches of water. If gas line pressure is higher, heater regulator damage could occur.

CAUTION

Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe 3/8" diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.

Installation must include a manual shutoff valve, ground joint union, and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Figure 12, page 14).

Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves.

CAUTION

Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.

Install sediment trap in supply line as shown in Figure 12, page 14. Locate sediment trap where it is within reach for cleaning. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into heater controls. If sediment trap is not installed or is installed wrong, heater may not run properly.

This means it can operate quietly and smoothly, offering comfort without the jarring temperature fluctuations that other systems may create.

Both models incorporate innovative safety features, including a built-in flue gas condensation sensor that ensures safe operation under varied conditions. Additionally, they include a user-friendly digital thermostat, which enables precise temperature control and can be programmed for optimal efficiency. Homeowners can easily customize their heating schedule, making it convenient to maintain a comfortable living environment while also conserving energy.

Another notable characteristic of the Vanguard VN6B and VN12A is their durable construction. Made from high-quality materials, these heating units are designed to withstand wear and tear, ensuring a long lifespan with minimal maintenance. Regular maintenance reminders are a feature, making it straightforward for homeowners to keep track of service needs.

In summary, the Vanguard Heating VN6B and VN12A models stand out in the market for their exceptional efficiency, smart technologies, and user-centric features. They are excellent choices for homeowners seeking reliable and environmentally friendly heating solutions that promise comfort year-round, all while keeping energy costs low.
