CONNECTING TO GAS SUPPLY

NOTICE: A qualified service per- son must connect heater to gas supply. Follow all local codes.

CAUTION: Never connect heater directly to the propane supply. This heater requires an

Propane

Supply

Tank

External Regulator

Installation must include a manual shutoff valve, 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 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 seal- ant that is resistant to liquid pe- troleum (LP) gas.

external regulator (not supplied).

Vent Pointing Down

Install the external regulator be- tween the heater and propane supply.

Installation Items Needed

Before installing heater, make sure you have the items listed below.

•external regulator (supplied by installer, see above)

•piping (check local codes)

•sealant (resistant to LP gas)

•manual shutoff valve *

•test gauge connection *

•sediment trap

•tee joint

•pipe wrench

CAUTION: Use only new, black iron or steel pipe. Inter- nally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2" diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.

Install sediment trap in supply line as shown in Figure 14. Locate sediment trap where it is within reach for cleaning. Locate sedi- ment 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.

CAUTION: Avoid damage to control. Hold fitting with wrench when connecting it to gas piping and/or fittings.

*An A.G.A. design-certified manual shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Pur- chase the optional A.G.A. design-certified manual shutoff valve from your dealer. See Accessories, page 25.

The installer must supply an external regu- lator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14 inches of water. If you do not reduce incoming gas pressure, heater regulator damage could occur. Install external regu- lator with the vent pointing down as shown in Figure 13. Pointing the vent down pro- tects it from freezing rain or sleet.

UNVENTED (VENT-FREE) PROPANE/LP GAS LOG HEATER specifications

The Vanguard Heating Unvented (Vent-Free) Propane/LP Gas Log Heater is a remarkable home heating solution that combines efficiency, convenience, and aesthetic appeal. Designed to deliver warmth without the need for traditional venting, this heater stands out for its innovative technology and user-friendly features.

One of the main attractions of the Vanguard unvented gas log heater is its ability to provide consistent heat while conserving energy. The unit operates using propane or LP gas, making it an excellent option for homes without access to natural gas. With a high heat output, it efficiently warms spaces while potentially reducing heating costs compared to conventional systems.

The design of the Vanguard heater incorporates advanced catalyst technology, which ensures that combustion is clean and efficient. This technology minimizes emissions, making it an environmentally friendly choice for homeowners concerned about their carbon footprint. Furthermore, the heater is equipped with an oxygen depletion sensor (ODS) that automatically shuts off the gas supply if oxygen levels fall below safe thresholds, ensuring peace of mind for users.

Aesthetically, the Vanguard model features realistic log designs that replicate the appearance of a traditional wood-burning fireplace. This adds warmth and charm to any living space. The adjustable flame height allows users to customize their heating experience to suit their needs or mood. The controls are designed for ease of use, allowing for simple operation whether the heater is used for primary warmth or supplemental heat.

Safety is a key characteristic of the Vanguard unvented gas log heater. Besides the ODS mentioned earlier, the heater is built with durable materials that ensure longevity and reliability. It can be installed in various locations, including bedrooms and living rooms, as long as the manufacturer's guidelines are followed.

Installation of the Vanguard heater is relatively straightforward, requiring minimal modifications to existing spaces. This flexibility makes it appealing for both new constructions and retrofits. Additionally, the absence of venting means that installation costs are often lower than with vented units.

In summary, the Vanguard Heating Unvented Propane/LP Gas Log Heater combines advanced technology, stylish design, and crucial safety features, making it a viable choice for those seeking efficient indoor heating solutions.
