VENT-FREE PROPANE/LP GAS HEATER

INSTALLATION

Continued

CONNECTING TO GAS SUPPLY

WARNING: This appliance re- quires a 3/8" NPT (National Pipe Thread) inlet connection to the pressure regulator.

WARNING: A qualified service 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 external regulator (not supplied). Install the external regulator be- tween the heater and propane/LP supply.

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 large enough diameter to allow proper gas volume to heater. If pipe is too small, undue loss of pres- sure will occur.

VP2200ITB

1/2" or greater

Installation must include equipment 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).

IMPORTANT: Install an equipment shutoff valve in an accessible location. The equip- ment shutoff valve is for turning on or shutting off the gas to the appliance.

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.

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.

IMPORTANT: Hold pressure regulator with wrench when connecting it to gas pip- ing and/or fittings.

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.

The Desa VP2200ITB and VP1600ITB are advanced portable heaters designed for efficient heating solutions in a variety of settings. Both models showcase innovative features and technologies that make them standout choices for residential and commercial use.

The VP2200ITB is a powerful unit designed to provide substantial heating output, making it suitable for larger spaces. With a robust heating capacity, it ensures rapid warmth in cold conditions. On the other hand, the VP1600ITB is a slightly smaller model, ideal for medium-sized rooms or personal areas. This makes both units versatile, catering to different space heating needs.

One of the most notable features of both models is their digital thermostat, which provides precise temperature control. Users can easily set their desired heating levels, ensuring optimal comfort and reducing energy wastage. The adjustable heat settings, ranging from low to high, allow consumers to tailor the heat intensity according to specific requirements.

Both the VP2200ITB and VP1600ITB incorporate advanced safety technologies. These include a tip-over switch that automatically shuts off the heater if it is knocked over, and an overheat protection feature that prevents the unit from reaching unsafe temperatures. These safety mechanisms make them suitable for use in homes with children or pets.

Energy efficiency is another significant characteristic of these heaters. They are designed to provide maximum heat output with minimal energy consumption, resulting in reduced electricity bills. The environmentally friendly design is complemented by quiet operation, making them perfect for use in bedrooms, offices, or any space where noise levels should be kept to a minimum.

The heaters also feature compact and portable designs, equipped with handle grips for easy transportation. This means they can be effortlessly relocated from one room to another, providing flexibility according to changing heating needs.

Additionally, their sleek aesthetics allow them to blend seamlessly into various decors, ensuring that functionality does not come at the expense of style. With a range of features and practical technologies, the Desa VP2200ITB and VP1600ITB models are ideal solutions for effective heating, delivering warmth, safety, and efficiency in one package.
