CONNECTING TO GAS SUPPLY

WARNING: A qualified ser- vice person must connect heater to gas supply. Follow all local codes.

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

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

Installation Items Needed

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

external regulator (supplied by installer)

piping (check local codes)

sealant (resistant to propane/ LP gas)

manual shutoff valve *

test gauge connection *

sediment trap

tee joint

pipe wrench

*An CSA design-certified manual shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Pur- chase the optional CSA design-certified manual shutoff valve from your dealer. See Accessories, page 28.

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 incom- ing gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure

13.Pointing the vent down protects it from freezing rain or sleet.

WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas.

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.

Sediment Trap

 

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 regulator. Hold gas regulator with wrench when connecting it to gas piping and/or fittings.

Desa Tech CGG2618P, CGG3630P, CGG3324PT Connecting to GAS Supply, External Regulator With Vent Pointing Down

CGG2618P, CGG3630P, CGG3324PT specifications

Desa Tech is a well-known name in the realm of innovative and efficient heating solutions, and its CGG2618P, CGG3630P, and CGG3324PT models exemplify the brand's commitment to excellence in design and functionality. Each of these products is tailored to meet specific heating needs while incorporating advanced technologies for improved efficiency and user experience.

The CGG2618P is a compact yet powerful gas heater designed for smaller spaces. With a maximum output of 26,000 BTUs, it can easily warm up a room quickly and efficiently. One of its standout features is the built-in thermostat, which allows users to set their desired temperature with precision, ensuring comfort without wasteful energy use. The heater also includes an electronic ignition system, offering hassle-free startup. Its sleek design and lightweight construction make it easy to move wherever heating is needed.

On the other hand, the CGG3630P boasts a larger capacity with a maximum output of 36,000 BTUs, making it ideal for larger rooms or even garages and workshops. This model features dual heat settings, allowing users to customize their heating experience based on the size of the space and the external temperature. The innovative flame sensing technology ensures that the unit operates safely by automatically shutting off the gas supply when the flame is not detected. Additionally, it is designed with a durable casing that can withstand the wear and tear of everyday use, ensuring longevity and reliability.

The CGG3324PT combines elements from both models to cater to versatile heating needs. With an output of 33,000 BTUs, it is suitable for medium to larger-sized spaces. This model is unique for its portability, equipped with wheels that make it easy to transport from room to room. It also features a piezo ignition system, which requires no external power source, enhancing its usability in power outages or remote locations. Furthermore, the CGG3324PT is designed with safety in mind, featuring an automatic shut-off function that activates in the event of overheating.

All three models from Desa Tech share a commitment to energy efficiency. Utilizing advanced combustion technologies, they minimize fuel consumption while maximizing heat output. This means not only lower energy bills but also a smaller carbon footprint. Additionally, their sleek designs add a touch of modernity to any space while providing efficient heating solutions.

In summary, Desa Tech's CGG2618P, CGG3630P, and CGG3324PT models offer a range of features and technologies that cater to diverse heating requirements.
