VENT-FREE PROPANE/LP GAS HEATER

AIR FOR COMBUSTION AND VENTILATION

WARNING: This heater shall not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ven- tilation air. Read the following in- structions to insure proper fresh air for this and other fuel-burning appliances in your home.

Today’s homes are built more energy effi- cient than ever. New materials, increased insulation, and new construction methods help reduce heat loss in homes. Home owners weather strip and caulk around windows and doors to keep the cold air out and the warm air in. During heating months, home owners want their homes as airtight as possible.

While it is good to make your home energy efficient, your home needs to breathe. Fresh air must enter your home. All fuel-burning appliances need fresh air for proper com- bustion and ventilation.

Exhaust fans, fireplaces, clothes dryers, and fuel burning appliances draw air from the house to operate. You must provide ad- equate fresh air for these appliances. This will insure proper venting of vented fuel- burning appliances.

PROVIDING ADEQUATE VENTILATION

The following are excerpts from National Fuel Gas Code. NFPA 54/ANS Z223.1, Sec- tion 5.3, Air for Combustion and Ventilation.

All spaces in homes fall into one of the three following ventilation classifications:

1.Unusually Tight Construction

2.Unconfined Space

3.Confined Space

The information on pages 4 through 6 will help you classify your space and provide adequate ventilation.

Unusually Tight Construction

The air that leaks around doors and win- dows may provide enough fresh air for combustion and ventilation. However, in buildings of unusually tight construction, you must provide additional fresh air.

Unusually tight construction is de- fined as construction where:

a.walls and ceilings exposed to the outside atmosphere have a con- tinuous water vapor retarder with a rating of one perm (6 x 10-11kg per pa-sec-m2) or less with open- ings gasketed or sealed and

b.weather stripping has been added on openable windows and doors and

c.caulking or sealants are applied to areas such as joints around window and door frames, be- tween sole plates and floors, be- tween wall-ceiling joints, be- tween wall panels, at penetra- tions for plumbing, electrical, and gas lines, and at other openings.

If your home meets all of the three criteria above, you must provide ad- ditional fresh air. See Ventilation Air From Outdoors, page 6.

If your home does not meet all of the three criteria above, proceed to Deter- mining Fresh-Air Flow for Heater Location, page 5.

Confined and Unconfined Space

The National Fuel Gas Code ANS Z223.1 defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggre- gate input rating of all appliances installed in that space and an unconfined space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space. Rooms communicating directly with the space in which the appliances are installed*, through openings not furnished with doors, are con- sidered a part of the unconfined space.

This heater shall not be installed in a con- fined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air.

*Adjoining rooms are communicating only if there are doorless passageways or ventila- tion grills between them.

VP1600ITB, VP2200ITB specifications

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.
